OSHA Announces “Targeted Industries in Construction” for silica enforcement.

Silica Enforcement in the Construction Industry

We should consider the OSHA’s new silica law a good thing.  The permissible exposure limit for silica has been cut from 250 ug/m3 to 50 ug/m3 – a five fold decrease.  We depend on our crew members.  The stakes are high.  Silica causes silicosis – lung disease, kidney disease, increased risk for cancer and death.  But there is a way to be safe.  Follow Table A and turn on the vacuum or water.

A special thank you to Rick Marshall of Association of Drilled Shaft Contractors for educating me and sharing the “U.S. Department of Labor Revises National Emphasis Program to Reduce or Eliminate Worker Exposure to Silica” with our members.

Here is a list of the “Targeted industries in Construction.”  And yes, shoring and micropile contractors are on this list.  Be safe and healthy!

The things we (and you) should ask when Preparing and Evaluating a Shoring Bid

Common questions we ask ourselves when preparing a shoring bid:

1.Have we clearly communicated the scope of work included in our shoring bid proposal?

2.Will the ground water table cause trouble?

3.How deep is rock?

4.Open hole drilling or casing?

5.Are there reasons to expect drilling obstructions?

6.Can sloping be used to avoid utilities and/or reduce shoring quantity?

7.What utilities will need to be located, exposed?

8.Shotcrete quantity?  Is our assumption reasonable?  Add and deduct.

9.Will rock be encountered at the face of excavation?  Line drilling, blasting, trimming in PWR/rock.

10.Aesthetics of permanent shotcrete?

11.One side forming?  Foundation wall overpour.

12.Will the owner have easement(s)/permission to drill under adjacent property/ROW?

13.Access, ramps, phasing of ramps?

14.Are there environmental concerns that could impact safety and/or scope of work, e.g. Brownfield sites?

15.LF of micropiles in base bid. What triggers add/deduct?

16.What is our client’s bid situation?

17.Are our assumptions reasonable?

18.What information do we need to get started?
