EM 385-1-1 safety program
Our safety program follows the U.S. Army Corps of Engineers Safety and Health Requirements Manual. Its requirements go beyond federal OSHA and Washington WISHA.
Competent persons
EM 385-qualified designated competent persons for fall protection, rigging and hoisting, and fire watch, with certified riggers and signal persons on staff.
Site safety and health officers
SSHO-qualified foremen assigned to our projects, with site-specific accident prevention plans and activity hazard analyses for each definable feature of work.
Base access
Most of our employees hold current badging for most areas of the bases we work on, so crews can start when the schedule says start.
Government paperwork
We work to UFGS specifications and UFC standards every day and know government submittal, closeout and O&M requirements.
We know how to get the work done on base
Getting people, trucks, equipment and materials on and off a military base is half the job. We do it every day and know the ins and outs.
Access and badging
We understand the badging process and the logistics of reaching all areas of the bases, and we plan crews, vehicles and deliveries around them.
Background checks
Routine background checks are run on all of our employees who serve sensitive sites.
Shipboard ventilation ductwork
We fabricate ship vent pieces for the ship repair contractors working aboard aircraft carriers and other vessels in port, from their drawings, their old pieces or our own measurements taken aboard ship. We can install it if requested. More on ship vent fabrication.
Removal, disposal and recycling
We properly remove, dispose of and recycle used equipment, refrigerants and recyclable materials, and handle the paperwork the base requires for them.
