Quotes from previous SDI projects

SDI was very creative and responsive to our needs. They met the challenge of very critical quality and tolerance requirements. SDI demonstrated excellent problem solving skills and customer service.

2004 Airport Improvement Project at Olympia Regional Airport
Tim Haddick, Federal Aviation Administration

We used SDI on a large, aggressively scheduled street improvement project that required careful planning and coordination. They always performed well.

Alaska Street Arterial Improvement Project
Joe Harrison, Tucci & Sons Inc.

Construction of this project under very difficult traffic concerns required skillful execution. SDI answered that call.
Pioneer Way Arterial Improvement Project
Steve Nichols, City of Tacoma Department of Public Works

The final grading plan for this project was very detailed and couldn't be completed in one shot. SDI responded very well to this by sending the right people and right equipment to the site at various stages as required. Many subcontractors depended on one another to complete their work according to a fragmented schedule; I didn't spend any time at all worrying about SDI meeting their obligations.

Clover Park Childcare Facility
PJ O'Brien, John Korsmo Construction

Unforeseen circumstances are a part of every project, especially when the site lies within an already established school campus. The unforeseens encountered on the Childcare Facility project were resolved much easier and more expediently than normal due to the ease of two-way communication and idea sharing with SDI.

SDI is 100% Drug Free!

Safety is an attitude; accidents and injuries are always preventable. SDI combines well trained construction professionals with a no-tolerance drug free workplace to create the safest working environment this industry can offer. Our proactive approach continues to protect our people, as well as those around us, and has lead to the following accomplishments:

  • Proactive AGC Safety Team member
  • Full time Safety Support Officer and dedicated Safety Support van
  • Dynamic Safety Committee comprised of nonsupervisory SDI employees
  • 100% comprehensive drug testing program
  • Comprehensive site specific safety plan for each project
  • Onsite safety meetings at least once a week
  • 2007 AGC Safety Team Award for Top 25 Lowest EMR
  • 2007 L&I experience factor .6000

SDI owns several machines that are equipped with a GPS system and onboard computer. This combination is used to control grading operations more precisely than a human operator has ever been able in the past. The GPS-equipped machines make one pass over an area when older means and methods required several. The system enables our crews to perform mass cuts and fills while simultaneously fine grading the same area. By combining these two functions, critical time is cut out of the construction schedule on every project.

The rover pack gives our grade engineer immediate cut/ fill information at every spot on the project. For this reason, SDI operations require far less surveying, a cost savings we pass on to each client. Having immediate access to cut/ fill information at every spot on the project means that all slopes from toe to top are built correctly the first time. It also means that storm detention ponds and other dramatic site contours are built 100% per design the first time.
