Concrete ADA Ramps Seattle Contractor

The Solution

We have a proven Design/Build process to  bring our customer’s sites into compliance, therefore reducing the likelihood of loss exposure or lawsuits. Our process will add value by:

  1. Getting an expert involved (licensed Professional Civil Engineer) in the design process who understands the constantly changing standards and specifications for your jurisdiction.
  2. Reducing lawsuits by preemptively upgrading the site to prepare them for possible litigants or advocacy groups.
  3. Reducing construction costs by having a defined scope of work before the construction begins. Fewer unknowns at the start of construction leads to fewer assumptions, more accurate pricing and also fewer change orders during construction.
  4. Reducing downtime and project completion duration by not needing to “engineer in the field” and providing a streamlined process with experienced industry experts. We install over 200 ADA ramps/year in the Seattle metro area.
  5. Working with one company throughout the entire process.
  6. Receiving a credit of 10% of design costs toward construction if you hire Rainier to complete the “build” aspect
