PURPOSE
The purpose of these policies and procedures is to provide a safe working environment for crane operators
and all site personnel. In addition, surveys of the crane equipment and the operation of the crane has
proven to be advantageous to the flow and expediency of work performed during any crane operation on
construction sites.

SCOPE
These crane procedures shall be followed on all Snyder Langston projects by all Snyder Langston
employees, subcontractors, subcontractor’s employees, crane rental companies, crane operators, crane
users, and any other persons, organizations, or contractors entering or operating crane equipment on any
Snyder Langston job site. These crane procedures will provide a method by which all cranes 14 1/2 ton
capacity or greater shall be surveyed. However, all cranes shall be operated in accordance with all
applicable regulations during use on Snyder Langston projects. Prior to use on all projects, each 14 1/2
ton capacity or greater crane shall be surveyed by a qualified person, designated by Snyder Langston.
Further, Snyder Langston may require any crane of any capacity to be subject to these requirements at its
discretion. The survey will include an inspection of the crane components, accessory gear, below the
hook lifting devices, the assembly and setup of the crane each time a crane enters the project. The
Surveyor shall review each crane operator’s credentials prior to allowing the crane to be operated.
Additionally, the surveyor shall monitor the crane operation and identify any procedures considered an
unsafe operating practice. These procedures should assist the subcontractor and crane company in
maintaining a safe working environment when cranes are used on Snyder Langston projects.

It should be recognized that it is not feasible to address every possible issue, situation, and circumstance
that may arise or be encountered on a project. Therefore, if there are conflicts or an unsafe condition that
occurs which is not addressed in this manual for a particular crane operation matter, the Snyder Langston
safety manager and Snyder Langston’s crane safety consultant shall be contacted immediately, prior to
commencement of the crane operation.

AUTHORITIES
The criteria and standards for the safe operation of cranes shall include the following:
1. Manufacturer’s recommendations and requirements
2. American National Standards Institute (ANSI)
3. American Society of Mechanical Engineers (ASME)
4. Occupational Safety and Health Administration (OSHA)
Note: Where the project is located in a state that has its own regulatory agency such a California’s Division of Occupational Safety and Health
Administration (Cal-OSHA), the crane equipment must meet the requirements of the state agency.

These criteria are the minimum standards that must be met in all crane operations on all Snyder Langston
projects. This crane safety procedure manual does not purport to restate all of these regulations, but
should be used for clarification and additional criteria to be adhered to while operating crane equipment
on Snyder Langston projects.

RESPONSIBILITIES

Snyder Langston
The Project Superintendent shall be responsible for scheduling of the surveyor 48 hours prior to the
arrival of each crane unit. The Project Superintendent has complete authority to cease any crane activity
or operation on the project which does not comply with this manual and these policies and procedures.
Based upon the information provided by the crane surveyor, the superintendent may also refuse to allow
any crane to proceed to operate until such time that the unsafe condition can be eliminated. Where a
crane operator declines to make a lift based on any safety concerns, Snyder Langston and its Project
Superintendent will provide full support to eliminate the unsafe condition. Upon notification of any

Page 3
 Revised: August 5, 1999

safety deficiency, the Project Superintendent will discuss a plan of action with the surveyor, sub-
contractor and crane crew to eliminate the safety deficiency.

Subcontractor
The subcontractor shall be responsible for providing Snyder Langston’s Project Superintendent with the
scheduled crane arrival time, general crane information such as type, size, and owner, anticipated lifts,
and any critical lift plans a minimum of 72 hours prior to scheduled arrival date of the crane. Each
subcontractor of Snyder Langston shall comply with this crane safety manual and these policies and
procedures. The subcontractor shall be responsible for providing each crane owner and all operators with
the crane safety criteria prior to bidding and/or arrival on any Snyder Langston project. Prior to
scheduling a crane, the subcontractor shall provide Snyder Langston with a completed “Pre-Erection
Hazard Analysis” form with a plan of action for items requiring corrective measures. The subcontractor
shall ensure that each item requiring corrective measures are corrected prior to the arrival of the crane
equipment. The subcontractor shall ensure that the crane and its crew are working within the guidelines
set forth by the governing authorities and Snyder Langston at all times. Any delays or down time due to
the determination or correction of any crane safety deficiency shall be at the subcontractor’s expense.
The subcontractor shall ensure that the crane company has provided Snyder Langston’s management with
a “certificate of insurance” and acceptable endorsement naming Snyder Langston & the project owner &
the subcontractor as additional insured on its general liability coverage 24 hours prior to the arrival of any
crane equipment to the job site.

Crane Surveyor
Snyder Langston retains the surveyor as a third party, independent crane safety consultant who is a
qualified person. He or she will provide the Project Superintendent, subcontractor and safety manager
with the results and findings of each crane safety survey. The crane surveyor shall ensure that the
requirements of this crane safety manual are followed by the subcontractors, crane crews, and crane
owners. The crane surveyor may serve as the liaison between the crane users and the project
superintendent. Upon identification of any safety deficiency that can not be eliminated prior to
commencement of the crane work, the surveyor shall report the deficiency to the subcontractor’s foreman
along with recommended plan of action. The surveyor shall inform Snyder Langston’s Safety Manager,
Snyder Langston’s Project Superintendent, and the crane owner respectively if discrepancies are
identified during the survey process that may affect the safe operation of the crane. If an imminent
danger exists by continued operation the crane operation shall cease immediately and appropriate action
shall be taken consistent with the reporting procedures set forth in this document.

Crane Owner
Each crane owner shall comply with this crane safety manual and these policies and procedures. Crane
owners providing equipment that is operated and maintained by personnel under their employ shall be
responsible for the training and qualifications of the operator. The crane owner shall provide all required
documentation such as manufacturers load charts, manufacturer’s maintenance criteria, and proof of
safety certifications consistent with the state and/or federal requirements for inspection by the crane
surveyor, Snyder Langston, the Project Superintendent, and/or the subcontractor. Where a safety
deficiency or unsafe operation is found, the crane owner shall provide the subcontractor and/or Snyder
Langston with a proposed plan of action to eliminate the safety deficiency. Any delays due to operations
or equipment that are adverse to these requirements shall be at the crane owner’s expense. Crane owners
shall provide Snyder Langston’s management with a “certificate of insurance” and an acceptable
endorsement naming Snyder Langston & the project owner & the subcontractor as additional insured on
its general liability and excess coverage 24 hours prior to the arrival of any crane equipment to the job
site. Snyder Langston shall provide the crane owner with evidence of builder’s risk insurance upon
request. Further, the crane owner shall be provided with the following Snyder Langston crane safety
documents:
1. Mobile Crane Safety Manual
2. Pre-Erection Hazard Analysis forms

LOAD TESTING OF JIBS AND ROLLING OUTRIGGERS

This section applies to all California projects and other
states that require proofload testing of crane equipment
All cranes that perform lifts with the jib attachment or rolling outriggers on Snyder Langston projects
shall have a current certification4 stating that the jib and rolling outriggers have been proofload tested by a
qualified person. Proof load tests shall be performed during the initial proofload testing and every four
years thereafter, unless a structural repair has been performed on the crane. If a structural repair has been
performed (even if the jib was not damaged) a load test shall be performed prior to placing the crane back
into service. No proof load test of the jib or rolling outriggers is required during the annual certification
as long as proof load testing of these components has been performed in accordance with the
requirements specified above. Where the crane owner elects not to test the jib or rolling outriggers, it
shall be noted on the certificate and the jib or rolling outriggers shall not be used until load testing has
been successfully completed. These requirements apply equally to telescopic and lattice boom cranes.

ANTI TWO-BLOCK DEVICES

This section is a minimum requirement for projects in all states.
Cranes manufactured after February 28, 1992
Telescopic boom cranes operated on Snyder Langston projects shall be equipped with a functional anti
two-block damage prevention feature. Lattice boom cranes operated on Snyder Langston projects shall
be equipped with a functional anti two-block damage warning feature.

Cranes manufactured before February 28, 1992

All cranes equipped with an anti two-blocking device shall be operated with the device fully functional
during all lifts conducted on Snyder Langston projects.

LOAD RATING CHARTS

This section is a minimum requirement for projects in all states.
A durable load chart with clearly legible letters and figures provided by the crane manufacturer or a
certified agent experienced and familiar with the characteristics of the crane equipment shall be securely
fixed (where the manufacturer’s load chart is provided in a binder or other book form, the chart shall be
located in the operator’s cab) to the crane in a location clearly visible to the operator or within reach of
the operator while at the control station. The chart shall contain a full and complete range of crane load
ratings, consistent with the manufacturer’s' recommendations, at all stated operating radii or boom angles
and for all permissible boom lengths, jib lengths and angles, also alternate ratings for use and non-use of
optional equipment on the mobile crane, such as outriggers and counterweights which affect ratings. The
chart shall also contain essential precautionary or warning notes relative to limitations on equipment and
operating procedures, including indication of the least stable position. In addition, no crane shall be
rerated unless such rating changes are approved by the certified agent. Load ratings shall be expressed in
terms related to method of measuring boom angle and length or lifting radius.

Cal-O.S.H.A. Title 8, plate V or equivalent proof for cranes located in states outside of California. See attachment
1 for example.
Page 10
 Revised: August 5, 1999

Interpretation
Where the actual boom angle does not match the values shown on the load chart, the value used must be
the next lower boom angle number. Where the actual load radius does not match the values shown on the
load chart, the value used must be the next higher radius number.

Example
The load is to be placed at a 55-ft radius at 47° boom angle. The load chart values are shown for 50-ft.
radius at 55° boom angle with the next value at 60-ft. radius at 45° boom angle. The capacity reflected at
the 60-ft. radius at 45° boom angle must be used for this example since no capacity values are given for
the actual load radius and boom angle.

CRITICAL LIFTS
A critical lifts is established where any one of the following conditions are created:
1. Where in the crane’s current configuration at any point during the lift, a gross
load weight exceeds 75% of the capacity of the crane, or 85% of the capacity
of the crane where tilt-up panels are erected.
2. A single lift that two or more cranes are used including tandem lifts and
tailing cranes.
3. Lifts made in close proximity of power lines as defined by the voltage
clearance specifications described above.
4. Lifts involving specialized or unique and complex rigging equipment.
5. Hoisting of suspended work platforms.
6. Static tower crane erection and dismantelment.
7. Making lifts below the ground level where the crane is positioned.
Note: Where the below the ground lift is minimal, a critical lift plan may not
be required.

Critical Lift Plan

Where a critical lift will be performed, a written critical lift plan shall be submitted to Snyder Langston
prior to commencing with the lift. The written plan shall include the following:
1. Crane manufacturer, capacity, and all specifications for the configuration to
be used for the lift.
2. Load chart data for the crane to be used to make the lift.
3. Total calculated weight of the load to be lifted including all rigging and other
deductions consistent with the manufacturer’s load chart.
4. Diagrams of the lift that provides geometrical conditions of the load, rigging,
and all crane positions during the lift. The drawing shall provide the
following:
A. Locations of all components to be lifted prior, during and after
the lift is completed.
B. Radius points.
C. Swing patterns.
D. In the event that the lift must be aborted, positions where the
load may be safely landed.
E. Areas where any personnel, public, and vehicles must be
evacuated during the lift.
5. Potential ground loading for each point of contact by the crane in selected
locations in which the crane will perform the critical lift.

Page 11
 Revised: August 5, 1999

6. Soil and subsurface data and information pertaining to the location on which
the crane used for the critical lift will be positioned. This information shall
be procured from an authoritative source such as a geotechnical engineer or a
professional civil engineer registered in the state where the project is located.
This information may be available from Snyder Langston for selected
locations on some projects.
7. An engineer shall use the data provided in #5 and #6 above to verify and
confirm the following:
A. That the soil and subsurface conditions are capable of
supporting all loads imposed during the critical lift.
B. That the designs of cribbing and other supports used under the
crane load points are appropriate to safely transfer such loads.
8. Signature and stamp on the plan by a registered professional engineer
licensed in the state in which the project is located, evidencing review of the
plan as meeting the requirements set forth in this manual and that all loads
and load information and calculations contained in the plan are approved,
acceptable and safe to perform.
9. Operator qualifications.
10. Method by which communication will be provided to the crane operator.
(Designated signal person, two-way radio, hard wire phone system, etc.)
11. A critical lift hazard analysis which identifies the particular hazards
associated with the lift and the means and methods to reduce, mitigate, or
eliminate the hazards.
12. Emergency action plan.
The written plan shall be submitted 72 hours prior to any critical lift for review by Snyder Langston’s job
superintendent and crane surveyor. No critical lifts shall be conducted prior to such approval.

The use of a crane or derrick to hoist employees on a personnel platform is prohibited, except when the
erection, use, and dismantling of conventional means of reaching the worksite, such as a personnel hoist,
ladder, stairway, aerial lift, elevating work platform or scaffold, would be more hazardous or is not
possible because of structural design or worksite conditions. If a crane suspended work platform is used,
its use shall be conducted in accordance California Code of Regulations, Title 8, § 5002. Where work is
conducted outside of California, Federal O.S.H.A., 29 C.F.R. 1926 § 550(g) shall be followed unless the
regulations of the state where the project is located exceed these requirements.

QUALIFICATIONS OF CRANE OPERATORS AND SURVEYORS

All persons who perform crane safety surveys or operate crane equipment on Snyder Langston projects
shall be adequately trained and experienced on the type of crane and lifts that are to be performed.
Effective June 1, 2000, Snyder Langston requires all crane operators to be certified under the CCO or an
equivalent program that has been reviewed by an independent assessment service (e.g. Buros Institute)
accepted by the Snyder Langston’s Safety Manager. Proof of CCO certification or its equivalent (as
defined under Crane Operator) shall be provided to Snyder Langston’s qualified crane surveyor or Project
Superintendent prior to commencing any crane operations. It shall be the responsibility of the
subcontractor to ensure that all operators hired or contracted with are qualified, trained, and experienced
prior to commencing with lifts on Snyder Langston projects. In addition, all crane surveyors shall be
required to complete CCO testing.
