Start:Aug 06, 2020

Duration:5 Minute(s)

Goal: this Cognitive Trail will increase the ability to apply Cal/OSHA safety standards for the construction industry.

Description: This Navitent will increase the successfulness of applying OSHA's safety standards. This information was taken from Cal/OSHA Pocket Guide f ... Read More

Summary: Safety Made Simple

Step 1

The next Steps cover Cal/OSHA safety regulations for Forms, Falsework and Vertical Shoring. Where appropriate, we have referenced the code from Title 8 of the California Code of Regulations.

The topics we will cover in this Navitent re:

-Definition
-Design of Falsework
-Erection of Falsework
-Inspection
-Access to Forms and Falsework
-Fall Protection

After each of the next Steps, select the 'successful' response to indicate that you have read and understand the Step.

Select 'successful' now and proceed.

Step 2

Definition

By definition concrete forms are considered falsework. Falsework, however, also includes support systems for forms, newly completed floors, bridge spans, etc. that provide support until appropriate curing or stressing processes have been completed.

The Steps 3 through 7 below detail selected Safety Orders

Step 3

Design of Falsework

-Concrete formwork and falsework must be designed, supported, and braced to safely withstand the intended load. 1717(a)(1)

-Falsework design, detailed calculations, and drawings must be signed and approved by an California Registered Professional Engineer (Ca PE) if the falsework height (sill to soffit) exceeds 14 feet, if the individual horizontal span length exceeds 16 feet, or if vehicle or railroad traffic goes through the falsework
Note: for other falsework, approval may be provided by a manufacturer’s representative or a licensed contractor’s qualified representative. 1717(b)(2)(B),(C).

-Falsework plans must be available at the jobsite

-Minimum design loads are as follows:
a. Total combined live and dead load: 100 psf.
b. Live load and formwork: 20 psf.

-Additional loads must be considered in the design. 1717(a)

Step 4

Erection of Falsework

-Falsework must be erected on a stable, level, compacted base and supported by adequate pads, plates, or sills. 1717(b)(4)

-Shore clamps (metal) must be installed in accord with manufacturer’s instructions. 1717(d)(2)

Step 5

Inspection

-Before pouring concrete on falsework requiring design approval, an California Registered Professional Engineer (Ca PE) or the engineer’s representative must inspect for and certify compliance with plans
Note: for other falsework, the inspection and certification may be provided by a manufacturer’s representative or a licensed contractor’s qualified representative.

-A copy of the inspection certification must be available at the jobsite

Step 6

Access to Forms and Falsework

-Joists (5 1/2 inches wide) at not more than 36 inches on center may be used as walkways while forms are placed

-A plank (12 inches wide) may be used as a walkway while joists are placed

Step 7

Fall Protection

-Periphery rails are required as soon as supporting members are in place
Note: the area under formwork is a restricted area and must be posted with perimeter warning signs.
