OSHA Advisory Committee for Construction Safety and Health

eLCOSH Editor's note:

The OSHA Advisory Committee for Construction Safety and Health (ACCSH) was authorized in the 1969 Construction Safety Act (US Code Title 40§3704, to advise OSHA on matters related to construction safety and health. It consists of five public representatives (one is normally from a State OSHA program, one from NIOSH, etc.), five labor representatives (normally from various Building Trades Unions) and five management representatives (primarily from contractor trade associations). The ACCSH often sets up work groups, which are open to the public, to draft positions on various topics or issues. These positions are then often voted on by the full ACCSH and those recommendations referred to OSHA for their consideration. These work products represent a lot of effort and thought by many individuals. They are posted here to make that work more easily accessible. This historical archive many serve as a resource to future regulators and safety advocates, so they don’t have to start from scratch. OSHA has removed some of these documents from their website which makes access difficult.

To the best of our knowledge this is a complete archive of ACCSH working group reports and recommendations. If you are aware of others, please contact us. For the most recent or future meetings, you can find information at http://www.osha.gov/doc/accsh .

Meeting Notes and Final Report

Engineering Workgroup Meeting, September 23, 1994
National Society of Professional Engineers
Alexandria , Virginia

The meeting was attended by Jim Lapping, William C. Rhoten Charles Worischeck, Charley Campbell, Michael Charles, Val Ericson, Lee Garrigan, Kevin Sikora, Dale Cavanaugh, Matt Burkart, Peter C. Huddleston, Don Miller, Pat Finn, J. A. Padgett, Jr.

Mr. William Rhoten served as Acting Chair.

Item 1 The commentary on the Meridian Report submitted by Charles Worischeck (NSPE) and reviewed during the July 25, 1994 meeting was approved for inclusion in the Workgroup final report.

Item 2, The definition of Engineer was approved as follows:

The term engineer is defined as a Professional Engineer, licensed or registered in the state where the work is to be performed, and who is designated and agrees to perform the required tasks as contained in this Part (1926)

Item 3 The following was also approved:

A site specific list of those operations or tasks that require the services of an engineer shall be compiled prior to the start of work. This list shall include a description of the engineering services required and shall be updated throughout the project to identify the designated engineer prior to the start of the designated operation or task and to incorporate newly identified tasks or activities requiring the services of an engineer.

Item 4 The following was approved on March 10, 1994 :

The "design professional" who is employed directly by the owner and who is not involved in the ways, means, and methods of the construction process should not be responsible for worker safety and health; and

Design work or other engineering practices required for safe construction should be performed by a qualified engineer employed by a contractor.

Item 5 The following was approved on July 25, 1994 :

Construction Employers shall notify the owner of requirements under OSHA regulations/standards to provide professional services and their intention to provide such services as required. This would include Licensed Professional Engineers, Certified Industrial Hygienist and Certified Safety Professionals.

Item 6 The following was approved on July 25, 1994 :

It is recommended that OSHA adopt the following general requirements to be applicable to all construction work:

Licensed Professional Engineer shall approve the erection (construction) sequence, the bracing and bolting procedures and sequences and design interim bracing and shoring as required.

Item 7 The following was discussed during the July 25, 1994 meeting without formal recommendations:

There was a general discussion regarding the qualifications of Competent Persons when they have been assigned duties that may require the services of a Licensed Professional Engineer. For example, inspecting shoring to determine if there is damage requiring reinforcement. 1926.703(b)(4).

In such instances the Competent Person shall be capable of determining when a Licensed Professional Engineer is required. In some instances where a Competent Person is assigned duties that may required a Licensed Professional Engineer OSHA might require that a Licensed Professional Engineer approve the Competent Person as being qualified to perform those specific duties. In other situations a Licensed Professional Engineer may be required to be immediately available to the Competent Person or the Competent Person would be required to remove employees from hazardous conditions until a determination is made by a Licensed Professional Engineer that a hazard does not exist.

There also may be conditions where Licensed Professional Engineer would be required to establish Standard Operating Procedures to be followed or monitored by a Competent Person approved by the Licensed Professional Engineer.

Item 8 The report prepared by Ernie Jorgensen (August 4, 1994) describing the duties of Competent Persons, Qualified Persons and Engineers is included for information.

Item 9 The report prepared by Kevin Sikora listing those standards that contain requirements for Qualified Persons is included for information.

Item 10 The definitions provided by NSPE are included for information.

Item 11 The Canadian Guidelines for Design and Inspection of Formwork and Falsework on Construction Projects is included for information.

Item 12 The American Society of Civil Engineers policy on Construction Site Safety is included for information.

ITEM 1

Engineering Work Group
ACCSH

Meetings of 5/9/94 & 7/25/94

Commentary on the use of the terms Professional Engineer, qualified engineer, structural engineer and similar terms in OSHA Construction Standards ( 29 CFR 1926 ) and the use of the terms "qualified person" and "competent person" as used in various sections of the Standards.

The comments are focused on the Final Report prepared by Meridian Research, Inc., dated August 9, 1993.

A-Recommended usage of description for Licensed Professional Engineer

NSPE recommends the use of the term " Licensed Professional Engineer " wherever a requirement for the signing and sealing of plans and documents is required.

The definition of Licensed Professional Engineer as used in the Standards should conform to the wording used in Subpart P - Excavations for a Registered Professional Engineer, the only change suggested being the substitution of "Licensed" for "Registered.

Since the use of many pieces of purchased equipment that meet the required specifications is common, it is recommended that the certification of these pieces be current and that the embossed seal of a Licensed Professional Engineer be applied to the documents certifying that the equipment continues to meet the Standard and has not been altered or allowed to deteriorate. My experience has been that much of this equipment is used for many years and often has defects caused by alteration or deterioration and should not be used.

B-Provisions in OSHA Construction Standards that require the services of a professional engineer.

References are to pages in the Meridian report for convenience.

1. Page 1 - Subpart L - Scaffolding

    1925.451 (b)(16) Replace qualified engineer with Licensed Professional Engineer.

    1926.451 (c)(5);(e)(9);(g)(3) make all three consistent by the use of Licensed Professional Engineer in place of registered professional engineer.

    1926.550 (a)(1) Replace qualified engineer with Licensed Professional Engineer. This change should conform to the definition in Subpart P-Excavations to provide for a Professional Engineer licensed in any state since much of this equipment is used in many localities.

Page 2 - Subpart N - Cranes, Derricks, Hoists, Elevators and Conveyors

    1926.550 (g)(4)(i) Replace qualified engineer or a qualified person with Licensed Professional Engineer.

    1926.552 (a)(1);(b)(7);(c)(17)(i) Make all three paragraphs consistent by using Licensed Professional Engineer instead of professional engineer or registered professional engineer.

    1926.552 (c)(17)(i) change last phrase to read: erected under the supervision of a Licensed Professional Engineer competent in this field.

Page 2 - Subpart P - Excavations

    1926.650 (b) Replace the term registered professional engineer with Licensed Professional Engineer. Replace the word registered with Licensed in the second paragraph.

Pages 3, 4, 5 Subpart P-Excavations

    Replace the term registered professional engineer with Licensed Professional Engineer wherever it occurs. (2)

Page 6 - Subpart Q-Concrete and Masonry Construction

    1926.703 (b)(8)(i) Replace the terms qualified engineer and engineer qualified in design with Licensed Professional Engineer.

    1926.705 (a);(k)(i);Appendix Replace the term registered professional engineer with Licensed Professional Engineer.

    C-Provisions in OSHA Construction Standards that imply or can be interpreted as implying that the expertise of a Professional Engineer is required.

Page 8 Subpart E-Personal Protective and Life Saving Equipment

    1926.104 (b) There is little question that the determination of anchorage or structural capacity to support the minimum weight would require an analysis by a structural engineer. Tie points should be determined in advance (during design) or analyzed-for capacity by a licensed engineer. There are few jobs with field personnel capable of this analysis. Needs a Licensed P. E.

Subpart F-Fire Protection and Prevention

    1926.152 (b)(4)(ii) There is considerable controversy over the design of automatic extinguishing systems by P. E.'s only or by Fire Control System Firms and state laws vary. The intent of this paragraph emphasizes the total system including adequate drains to safe location and liquid-tight wall-floor joints. The design of the total system undeniably requires the expertise of a Licensed Professional Engineer.

Page 9 - Subpart L - Scaffolding

    1926.451 (c)(1);(c)(2);(c)(3)- The use of standard 2" O.D. steel scaffolds is well defined. The use of other sizes of steel tubing or other materials which may be used calls for an engineering analysis to assure sufficient strength and stability. I suggest the use of a Licensed Professional Engineer be required for this purpose.

Page 10 - Subpart L - Scaffolding

    1926.451 (h)(1);(h)(6) Masons' adjustable multiple-point suspension scaffolds seem, in general, to be loosely specified. It is possible that providers of this equipment issue instructions with this equipment, however it seems that better definition of the criteria should be part of the Standard. The Meridian comment that a Licensed Professional Engineer may be required is correct, particularly in the instance of the provision of additional beams and the change of spacing for overhangs exceeding 6'6".

    1926.451 (w)(1) Float or ship scaffolds are generally well specified, however the Meridian comment on substitute designs is correct and the use of a Licensed Professional Engineer should be required.

Pages 11 & 12 - Subpart M-Floor and Wall Openings 1926.500 Guard Rails, Handrails and Covers

    The Standards cover common usages, however the specific details of the entire protection systems may not necessarily fulfill the basic requirements for strength. The definition of "minimum deflection" defies quantification. A particular source of trouble is the attachment of protective devices on odd shaped structures. It would appear that some method of field testing for required strength or certification by a Licensed Professional Engineer is in order.

Pages 13, 14 & 15 - Subpart N-Cranes, Derricks, Hoists, Elevators and Conveyors

    1926.550 g(2) The determination of modifying (if only temporary) of the structural integrity of a structure to provide for access by means other than crane or derrick supported platforms would certainly require the expertise of the Licensed Professional Engineer who designed the structure

    1926.550 g(5)(vi) The design of the personnel platform as well as the witnessing of the proof test and the design of modifications to correct any deficiencies should be performed by a Licensed Professional Engineer.

    1926.550 (g)(6)(vii) The body belt/harness system should be an integral part of the personnel platform design and therefore should be designed by a Licensed Professional Engineer, particularly in the attachment of the fall system to the platform if industry-standard lanyards are used.

    1926.552 (c)(16) Material Hoists, Personnel Hoists and Elevators

    The design of these devices should be performed by a Licensed Professional Engineer and recertified from job to job to insure that modifications made or possible deterioration have not affected safe use for the purpose intended. ( I did not have ANSI A10.4-1963 to refer to)

Page 15 - Subpart 0-Motor Vehicles, Mech. Equip. & Conveyors

    1926.603 - Pile Driving Equipment- (a)(12) The design of special devices, other than standard equipment provided by the manufacturer, used to support or stabilize pile driving (and other) equipment should be designed by a Licensed Professional Engineer, preferably provided by the manufacturer of the original equipment. The design of the original equipment should be performed by a Licensed Professional Engineer and recertified for use periodically.

Pages 16, 17 & 18 - Subpart P-Excavations

    1926.651 (c)(1)(i) The design of structural ramps for access or egress from excavations should be performed by a Licensed Professional Engineer.

    1926.651 (h)(1) The design of special support or shield systems should be performed by a Licensed Professional Engineer.

    1926.651 (i)(1);(i)(2);(i)(2)(i);(i)(3) A Licensed Professional Engineer should required to determine the stability of adjacent structures and to design appropriate support systems.

    1926.652 (e)(1)(iii) and(iv)(C. W. Addition). The design for the bracing and re-bracing of excavation support systems must be performed by a Licensed Professional Engineer if the system sequences do not conform with standard forms of support in the Standards. Where special designs (other than those in the Standards) are required, the sequence of removal or re-bracing of should be part of the original P. E. design or by consultation with the P. E. if changed conditions occur.

Appendix B - (c)(3)(iii) While a competent person is allowed to make such judgments, the combination of loads possible make it advisable to consult with a Licensed Professional Engineer where a combination of these factors is present.

Appendix D - Do not see this as requiring other than a competent person

Pages 19, 20, & 21 - Subpart Q-Concrete and Masonry Construction

    1926.701 - Gen'l Requirements - A Licensed Professional Engineer should be required to determine if a concrete structure is capable of supporting the loads intended to be placed on it.

    1926.702 (e)(1) Supports for concrete pumping systems where supported on the ground or on other continuous supports such as floors or roofs can be satisfactorily planned by a competent or qualified person. Where the concrete pumping system is elevated or rises vertically, the support system should be designed by a Licensed Professional Engineer with due regard for thrust created by pumping pressures as well as weight.

    1926.703 (a)(1) General Requirements for formwork - I did not have ANSI A10.9-1983 for reference (Appendix), however the loading of forms and the structural design to provide for the combination of vertical, lateral and impact loads require the expertise of a Licensed Professional Engineer both in support and in suitability of the form for the purpose intended.

    1926.703 (b)(4) Shoring equipment - Shoring equipment should be recertified for use on each job, however a Licensed Professional Engineer should be required to determine the shoring strength and to determine the required reinforcement. Deterioration or modification of shoring equipment should be assessed before erection by a Licensed Professional Engineer.

    1926.704-Requirements for Precast Concrete

    (a) It would appear that a licensed Professional Engineer should analyze and design the erection sequence and the interim bracing and shoring systems until permanent connections are completed.

Page 21- Subpart R-Steel Erection

    1926.750 (a)(1),(2)
    1926.752 (d)(4)

    A licensed Professional Engineer should analyze and design the erection sequence, the bracing and bolting procedures and sequences used on multi-story structures. (This might better be a general requirement)

    (This entire section is, I believe, being discussed by another advisory group. This item should be brought to their attention.)

Page 22 and 23- Subpart S-Underground Construction, Caissons, Cofferdams and Compressed Air

    1926.800-Underground Construction

    (c) There is little question that a licensed Professional Engineer should determine the structural integrity of underground facilities during all phases of construction.

(o)(1),(2),(3)(i)(A,B),(iii),(v),(vi),(vii),(viii),(4)(i), (iiA)

All supports, temporary or permanent, should be designed by a licensed Professional Engineer experienced in underground work.

(o)(3)(iv)(A),(B)

Normally the design provided by the owner provides for the use of torque wrenches, the necessary torque and the testing frequency. If this is not the case, a licensed Professional Engineer should determine such requirements.

    1926.803 (b)(10) The medical lock should be designed by a licensed Professional Engineer, and,in addition, should be certified for use at the beginning of construction and recertified periodically during construction on long projects.(1 yr.or more)

    1926.801 Caissons
    1926.802 Cofferdams

    Caissons and Cofferdams should be designed by a licensed Professional Engineer. (addendum to the Meridian report)

Subpart T-Demolition

    1926.850 - Preparatory Operations

    (a) For multiple story buildings, a licensed Professional Engineer should make this survey. For single story buildings a competent person shall determine if a Licensed Professional Engineer is required to analyze demolition procedures. Competent persons making these inspections should have immediate access to a licensed Professional Engineer qualified to determine stability and to design support systems as required.

    (b) The shoring and bracing of walls and floors in damaged multiple story buildings should be designed by a licensed Professional Engineer. (Addenda to Meridian report)

    (k) Sidewalk sheds or canopies should be designed by a licensed Professional Engineer for all loading conditions expected. (Addenda to Meridian report)

    1926.857- A licensed Professional Engineer should be required to analyze the stability of the structure.

    1926.858- A licensed Professional Engineer should determine if demolition procedures will overstress structural members. (steel or any other material)

    1926.859- Competent persons making these inspections should have immediate access to a licensed Professional Engineer qualified to determine stability and to design support systems as required.

Subpart W-Rollover Protection Structures

    1926.1001(a) 1926.1003(a)(1)

    A licensed Professional Engineer should be required to design these structures.

Subpart X-Stairways and Ladders

    1926.1053(a)(22),(23) - A licensed Professional Engineer should design employer-built or installed safety devices to conform with these standards.

INTRODUCTION

The Occupational Satiety and HEalth SUbcommittee of the Environment, Safety and Health Advisory Committee (ESHAC), Department of Energy (DOE) requested that Meridian Research, Inc., under the terms of Meridian's subcontract with Pacific Northwest Laboratories' contract with the DOE, identify and interpret all provisions in OSHA's Construction Industry standards (29 CFR 1926) that either specifically require the services of a professional engineer or could be interpreted as requiring such services.

The first section of the report presents the actual text of those provisions of the construction standards that specifically call for the services of a registered professional engineer. The second section of the report, which begins on page 7, presents the actual text of those provisions of the standards that could be interpreted as implying that an employer may have to obtain the services of an engineer to achieve compliance. In other words, the regulatory provisions in the second part of the report imply, rather than specify, that such services are or may be necessary to achieve compliance. For example, several provisions in the construction standards require that a "competent person" design a particular piece of equipment. This "competent person" may need to be a professional engineer, depending on the complexity or uniqueness of the design, local regulatory requirements, and other considerations. In other cases, an employer has the option either of purchasing a piece of equipment meeting the standard's specifications or of hiring an engineer to design the equipment to meet these specifications. Because the requirements in the second part of this report are implied rather than specified, they are subject to interpretation. The interpretations in this report are not official; for an official interpretation of these requirements, readers should contact the Occupational Safety and Health Administration.

(b) "Accepted engineering practices" means those requirements which are compatible with the standards of practice required by a registered professional engineer.

"Registered professional engineer" means a person who is registered as a professional engineer in the state where the work is to be performed. However, a professional engineer registered in any state is deemed to be a "registered professional engineer" within the meaning of this standard when approving designs for "manufactured protective systems" or "tabulated data" to be used in Interstate commerce.

"Stable Rock" means natural solid mineral material that can be excavated with vertical sides and will remain intact while exposed. Unstable rock is considered to be stab;e when the rock material on the side or sides of the excavation is secured against caving-in movement by rock bolts or by another protective system that has been designed by a registered professional engineer.

"Tabulated data" means tables and charts approved by a registered professional engineer and used to design and construct a protective system.

1926.651 General Requirements

(i)(2) Excavation below the level of the base or footing of any foundation or retaining wall that could be reasonably expected to pose a hazard to employees shall not be permitted except when:

... (iii) A registered professional engineer has approved the determination that the structure is sufficiently removed from the excavation so as to be unaffected by the excavation activity; or

Mr. Jim Lapping
Building and Construction Trades Department AFL/CIO
815 Sixteenth Street NW - #600
Washington D.C. 20006

Dear Jim:

In connection with our participation on the ACCSH Engineering Work Group and in consonance with the assignment to review the OSHA standards for the use of the words/phrases competent and qualified I have the following observations to offer. In the past we have focused on this data as it appeared in the construction standards (1926). This. time I conducted a total review of all the standards and this included General Industry (1910), Maritime (1915) and Longshoring (1917).

In the full volume of standards the word competent is used 229 times within 112 sections; qualified is used 276 times within 129 standards; and, engineer(s) is used 157 times within 77 sections. The variables are considerable. The basics consist of Competent Person, Qualified Person and Engineer(s). However the other uses range from "a person qualified", "qualified Engineer" to a "competent person qualified".

The duties associated with being designated as a Competent Person, Qualified Person, and Engineer are similar in many instances yet they also have distinct definitions relating to various task descriptions. Engineer is used in a rather empirical fashion. Typical task assignments for engineers are:

  • Design
  • Verify
  • Approve
  • Inspect

We have taken the liberty to interpret some of the language to develop consistency in presenting the data. For instance; the process of design appears fairly easy to interpret. It often involves the development of data, tabular material, specifications, etc. from scratch. The word analysis is frequently used but it generally seems to be a second stage after the design process. We have combined this to be either verify or approve.

We have limited this task to those entries keying on the words engineer and engineers. Occasionally the word engineering is used in a fashion to require an engineer's services and this has been included.

Dear Mr. Lapping:

Attached is the report on the use of the terms "qualified" and "qualified person" in the OSHA Construction Industry standards (29 CFR Part 1926). The report is provided in response to the discussions held during the March 10, 1994 meeting of the ACCSH Engineering Work Group concerning the use of the term "qualified person" in Subpart P-Excavation, of the construction standards and fulfills action item 6 of the meeting minutes distributed on March 11, 1994.

The report identifies the paragraphs and provides the actual text of provisions of the construction standards that include the terms "qualified person" or "qualified." As indicated in the report, the term "qualified person" is not used in Subpart P but is used throughout the other subparts of the standards. The term "qualified" is also used throughout the standards and in general its application is both clear and consistent.

If you have any questions or comments regarding the above information or the attached report, or if I can be of any other assistance, please feel free to call me at (301) 585-7665.

Sincerely,

Kevin

From: Arthur Schwartz
Subject: Response to Request for Definitions

Per your request, below is a list of commonly understood definitions of the following terms and their general application to the engineering design and construction process. I have put the definitions in order from lowest to highest level of scrutiny. Some of the terms are very close in definition with subtle differences:

  1. Observe - - to take note of, to visually watch.
  2. Review - - to evaluate, assess, examine
  1. Inspect - - to look, to view or oversee for the purpose of ascertaining the quality or condition of the thing for the purpose of examination.
  2. Approve - - to be satisfied with, confirm, ratify, sanction,or consent to some act or thing done by another.
  3. Verify - - to confirm, attest to, or substantiate by oath.
  4. Design - - To form a plan, drawing or depiction of an original plan or conception to be used in the manufacturing or construction process. Following design, the licensed engineer is expected to sign and seal the plan, drawing, etc.

Sign - - to affix one's name to a writing or instrument for the purpose of authenticating it or to give its effect as one's act. In general, the signature accompanies the seal.
Seal - - a particular sign made to attest in the most formal manner, the execution of an instrument. Under the engineering licensing laws, the seal is an indication by the licensee that the work was performed under the licensee's direction and control and shall be placed on all specifications, reports, drawings, plans, design information, and calculations whenever presented to a client or any public or private governmental agency.

In the context of general design/construction issues, it would seem that "Observe," "Review," "Approve," and "Design" (including "Sign" and "Seal") would mostly apply to the activities of the design engineer in connection with the completed project/facility while "Inspect" and "Verify" would apply generally to the activities of the engineer retained by the construction contractor.

In contrast, in the context of issues relating to construction site safety, it would appear that "Observe" would apply to the activities of the design engineer. All of the other definitions would apply to the engineer retained by the construction contractor in connection with the means, methods, techniques, sequences, procedures and safety programs relating to construction.

New Guideline from Ministry of Labour

In October 1993, the Ontario Ministry of Labour issued a new guideline called Design and Inspection of Formwork and Falsework on Construction Projects.

The guideline is intended to help professional engineers, constructors, employers, supervisors, and workers with practical ways of complying with the construction regulations that apply to formwork and falsework installations.

Specifically the guideline addresses the following points:

  • the types of formwork and falsework that must be designed by a professional engineer
  • the situations where "standard" designs may be permitted
  • the situations where otherwise "standard" designs must be specifically designed for the site conditions or application, and
  • the selection and appointment of competent workers to carry out inspections of formwork and falsework.

The test of the Ministry's guideline is reprinted below.

Questions or comments on the guideline should be directed to your local Ministry of Labour office.

Design and Inspection of Formwork and Falsework on Construction Projects

1.0 INTRODUCTION

When the amendments to the Regulations for Construction Projects (Ontario Regulation 213/91) came into effect in August of 1991, the types of falsework structures required to be designed by a professional engineer were expanded to include additional types of formwork installations. The purpose of these amendments was to address the increasingly complex nature of these temporary structures by providing more information regarding their design, installation, and removal. In addition, to ensure that these temporary structures are constructed in accordance with the design drawings, a written inspection report is also required prior to the placement of concrete.

The purpose of this guideline is to clarify the various types of falsework. formwork, and shoring installations which must be designed by a professional engineer under the requirement of the regulations and to provide guidance for practical procedures for the field inspection of these structures.

2.0 DEFINITIONS AND TERMINOLOGY

2.1 Terms Defined in Regulation

The following definitions have been extracted from Section 1. subsection (1) of the Regulations for Construction Projects (Ontario Regulation 213/91). and are provided below for reference in this guideline:

2.1.1 "competent worker". in relation to specific work, means a worker who.

  1. is qualified because of knowledge. training, and experience to perform the work,
  2. is familiar with the Occupational Health and Safety Act and with the provisions of the regulations that apply to the work, and
  3. has knowledge of all potential or actual danger to health and safety in the work.

Note: In the context of formwork and falsework inspections the competent worker must be able to read and interpret formwork and falsework drawings and have a good knowledge of scaffold and shoring systems.

2.1.2 "falsework". in relation to a form or structure, means the structural supports and bracing used to support all or pan of the form or structure:

2.1.3 "form" means the mould into which concrete or other material is to be placed: 2.1.4 "formwork" means a system of forms connected together:

2.1.5 "professional engineer" means a person who is a professional engineer within the meaning of the Professional Engineers Act. 1984.

2.2 Terminology

In addition to the definitions extracted from the regulations. the following terms are defined for the purposes of this guideline:

2.2.1 "flying formwork" refers to a formwork system which is designed to be hoisted between levels as a unitized structure and depends on its own structural integrity during hoisting operations:

2.2.2 "formwork contractor" refers to the employer who is responsible for the erection or installation of the formwork and falsework and who may be a subcontractor, a general contractor. or the constructor:

2.2.3 "formwork engineer" refers to the professional engineer who is responsible for the coordination of the overall formwork, falsework, and shoring design under the requirements of Section 89:

2.2.4 "gangforms" refer to large form panels designed to be hoisted as a unit for convenience in erecting, stripping, and re-use;

2.2.5 "knock-down formwork" refers to a formwork installation constructed on site and supported by traditional falsework and proprietary shoring equipment and which is not intended to be moved as a unitized system:

2.2.6 "panel" refers to a unitized sectional form intended to be connected together:

2.2.7 "permanent structure engineer" refers to the professional engineer responsible for the design and construction of the permanent building or structure:

2.2.8 "proprietary equipment" refers to equipment or hardware normally designed and manufactured under patent or similar arrangements;

2.2.9 "regulations" refer to the Regulations for Construction Projects, Ontario Regulation 213/91;

2.2.10 "specialty formwork" refers to a formwork system specially designed for a particular type of concrete structure or concrete placing technique.

3.0 DESIGN REQUIREMENTS

3.1 Formwork and Falsework (Designed by a Professional Engineer)

Formwork and falsework structures generally fall into three broad categories: flying formwork. knock-down formwork. and specialty formwork. The following describes the types of formwork and falsework installations which are required to be designed by a professional engineer as referenced in Section 89 (l ) of the regulations.

3.1.1 Flying Formwork

  1. Slab Panel Forms
    Slab panel forms are large prefabricated horizontal units of formwork. designed to be hoisted as a unitized structure and to rely on their own structural integrity during hoisting operations. They include all of the necessary braces. trusses. frames, and components.
  2. Wall Panel Forms
    These forms, which are also sometimes refer red to as gangforms. are large prefabricated vertical units of formwork intended to be hoisted as a unit and to rely on their own structural integrity during hoisting operations. They normally include access work platforms as an integral part of the formwork structure. These types of forms must have the crane attachment points indicated on the design drawings and clearly identified on the form panel.

3.1.2 Falsework and Knock-Down Formwork (Built-in-Place)

  1. Slab Formwork. Falsework. and Shoring
    This covers the broad range of temporary structures erected to support the forms during the placement of concrete. It is normally composed of vertical shoring, frames. trusses, beams and associated bracing and is not intended to be moved or hoisted as a unitized structure.
  2. Wall Formwork and Bracing
    Built-in-place wall formwork which is over 3.8 metres (12' 6") in height is included in this category.
  3. Column Formwork and Bracing
    Column formwork which is more than 3.8 metres (12' 6") in height is included in this category. The design drawings may include typical details and alternative bracing arrangements to allow for practical erection and construction methods to address site conditions.

3.1.3 Specialty Formwork Systems

These specially designed formwork systems normally incorporate a specific concrete placement technique and a special removal and installation sequence. Examples include concrete slip forms, silo formwork systems. chimney forms. tunnel lining forms, and self-supposing beam and column formwork structures. The design drawing for these systems must include the concrete placement procedures and the installation and removal procedures.

These types of formwork panels are required to be designed by a professional engineer: however, the drawings may be standardized and are not required to reference specific projects.

3.2.1 Prefabricated Panels

Many wall forming systems are constructed from a series of modular prefabricated panels and connected by specialized proprietary hardware. These systems are used extensively in low-rise building construction for concrete walls which are less than 3.8 metres (12' 6") in height.

The drawings and written instructions for these systems must be approved by a professional engineer and should contain details of the connecting hardware, concrete pouring rates and placing sequence, and relevant installation instructions. These documents are not required to reference specific projects but should indicate standard details to address typical site conditions.

The inspection for this type of formwork should be performed by a competent worker designated by the formwork contractor. The designation by a professional engineer would not normally be necessary unless an engineer had specifically designed the formwork for the project or structure.

3.2.2 Knock-Down Formwork

Knock-down or built-in-place formwork for walls and other irregularly shaped structures is normally constructed from plywood and timber members and connected by proprietary hardware. When this type of formwork is to be constructed to a height of 2.4 metres (8' 0") or greater. but less than 3.8 metres (12' 6"), standardized drawings for typical arrangements must be approved and reviewed by a professional engineer. As indicated above for prefabricated panels, these documents are not required to reference specific projects but should indicate standard details which address typical site conditions. Where changes are necessary which are not covered in the standardized drawings, the formwork contractor should advise the engineer in order to provide further design information. The drawings and instructions should be kept on the project.

As indicated in 3.2.1. the inspection for this type of formwork must also be performed by a competent worker designated by the formwork contractor. The designation by a professional engineer would not normally be necessary unless the engineer had specifically designed the formwork for the project or structure.

3.3 Formwork Engineer

In many cases several professional engineers may be involved in portions of the formwork design. This occurs quite often where formwork and shoring design services are provided by suppliers of proprietary equipment. The design provided is usually applicable to the proprietary equipment only. Such items as mud sills, ledgers, timber members. and other critical components supplied by the contractor are often not included in the design by the supplier.

In addition. the engineer providing the design services from the proprietary equipment supplier may not wish to perform site inspections or designate a competent worker or engineer as required by the regulations.

In both these situations the constructor or formwork contractor must employ or retain a professional engineer (the formwork engineer) who will be responsible for the coordination of the overall formwork and shoring design, including the designation of the competent worker as required by Section 89 of the regulations.

Where it is necessary to revise or change the original formwork design due to site conditions or other circumstances, the formwork engineer must be advised by the formwork contractor or constructor. It is the responsibility of the formwork contractor and constructor to ensure that the appropriate approval for the design changes has been obtained from the formwork engineer.

4.0 INSPECTION

Section 89. subsections (3) and (4). of the regulations require that formwork and falsework installations be inspected by a professional engineer or by a competent worker designated in writing by the professional engineer prior to the pouring of concrete. A written report of the inspection is also required.

4.1 Purpose

The purpose of these field inspections is to verify that the formwork and falsework has been constructed in accordance with the design of the formwork engineer as indicated on the design drawings. The inspection is not intended to provide a procedure to approve design changes or deviations from the design drawings.

Although the regulation allows for the formwork inspection to be carried out by a competent worker designated by the formwork engineer. it is recommended that for complex installations the formwork engineer or a designated engineer perform the inspection.

4.2 Deviations and Design Changes

When deviations or design changes are necessary. it is the responsibility of the constructor and formwork contractor to advise the formwork engineer in order to obtain approval. Where the formwork engineer approves a design change. the formwork contractor and constructor should be advised in writing and the drawings revised as necessary. These revisions may sometimes be addressed by a small area drawing which indicates the changes rather than a revision and issuance of the entire drawing or set of drawings.

The designated competent worker cannot approve design changes. The responsibility of the designated competent worker is to inspect the installation and provide a written report indicating whether the formwork has been constructed in accordance with the design drawings. Where deviations are observed. they should be noted in the report and forwarded to the formwork contractor and constructor for further action.

4.3 Designated Competent Worker

In certain circumstances, it may be practical for an employee of the constructor or formwork contractor to be the designated competent worker. This procedure is acceptable provided the worker has been identified in writing following consultation with the formwork engineer.

The designation of the competent worker must be set out in writing by the formwork contractor or constructor and acknowledged by the formwork engineer. It is recommended that the . information describing the designation be provided on a standard form similar to the one attached to this guideline.

CONSTRUCTION SITE SAFETY

ASCE, while recognizing that construction activities can be dangerous, believes that improvements can and should be made in safety on construction sites, and further believes that attention and dedication to safety by all participants are essential to achieving these improvements. ASCE supports legislation which includes the following: 1) preserves the construction contractor's responsibility and authority for general supervision of a construction project and for construction site safety; 2) provides that the general or prime construction contractor place his or her employee or consultant, who is trained and qualified in construction safety principles, rules and practices appropriate for the particular project, in responsible charge of the safety aspects of each project, and give that person appropriate authority; 3) provides that critical temporary construction needed to facilitate completion of a permanent facility be designed by a registered professional engineer who is a consultant to or an employee of the construction contractor; and 4) provides for development of safety training and education programs and supports their utilization by government inspectors, construction contractors, construction employees and engineers.
