Design Build


HDL partners with contractors for this fast-track method of project delivery.  We are accomplished in performing the roles of designer and quality control inspector for General Contractors as well as performing quality assurance reviews and inspections for Owners.   Currently, HDL is providing geotechnical/civil design services and performing material testing for the GCI TERRA Southwest Project.  This design build project provides communication towers and related equipment at seven village sites and four mountain top sites in the Bristol Bay region.  HDL served as the Independent Quality Firm responsible for quality assurance of both design and construction on the award winning 30.5 million dollar Glenn Highway/Bragaw Street Interchange project for the State of Alaska DOT&PF.  Additionally HDL has also provided civil/site design services including grading, storm water drainage, water distribution, sanitary sewer, and natural gas distribution to establish a new fuel maintenance dock at Elmendorf Air Force Base.
