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 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?

Developer taps into demand created by Triangle’s growing senior population

DAVID BRACKEN
RALEIGH

With the Triangle’s job market proving itself to be among the best in the country in recent years, this region has been adding new residents at a faster rate than all but a handful of other metropolitan areas.

That population growth is driving demand for all sorts of real estate. An influx of millennials is helping fuel the apartment construction boom, while the single-family market has been buoyed by established families moving here in search of better-paying jobs.

Another area that is likely to benefit in the coming years is senior living communities, as older parents relocate to the Triangle to be closer to their children and grandchildren.

Drilling Safety – Always Critical

I am sharing an email from one of our industry safety leaders:

All,

This is yet another unfortunate reminder of how dangerous / deadly our work can be.  While the exact details are not known as yet, it is thought that some type of entanglement incident occurred between an employee and the rotating drill string (in this case the cfa) you see in the photos.

It is a reminder of just how close employees  get to “the work” during a tieback installation.  It is possible that the communication between the drill rig operator and the helper were poor, the employee was wearing loose fitting clothing (i.e. a safety vest), he was cleaning the auger flights with a 2×4 or some other object, the emergency shut off switch was not functional, or some other probable cause, leading up to the loss of this young man’s life.

Please try to use this article a learning tool.  Resist the temptation to look up the affected contractor and better spend your time looking at your own operations.  What can we do as individuals or as an association to help prevent a tragic accident such as this from occurring once again? Observe how you install a tieback or micropile.  How close do your employees get to the rotating drill steel?  How good are the communications between the operator and helper?  Does the emergency shut off switch actually work?  Do you inspect / check it every shift?   Remember too, this type of incident could take place on a drilled shaft project, any CFA type project, soil mixing or slurry wall project or any other environment where we have to work in close proximity to a rotating object.

Use this unfortunate accident to serve as a deadly reminder of just how dangerous our work is.
