Project Overview x
The Chiniak Highway curves along the northeast coast of Kodiak Island, alternating between river crossings and mountainous terrain. Much of the highway was originally constructed during World War II to provide access between the military bases in Kodiak and Chiniak. The road was improved over the years and now provides the sole access between residential, commercial, and recreational areas south of the City of Kodiak. Kodiak receives frequent storms from the North Pacific Ocean and nearly 80 inches of rain annually. Several areas of the highway were threatened by erosion along the coast and near bridges and culverts due to flooding. This project constructed improvements at nine separate locations between mileposts 19 and 43 of the Chiniak Highway, focusing on repairing erosion damages and protecting the highway from future erosion. Project elements included riprap, culverts, soldier pile walls with rock socket foundations, roadway realignment, and guardrail.
During construction, HDL set up and equipped a remote lab and field office to provide construction inspection and material testing services. HDL’s construction administration (CA) team was present for all construction activities – a challenge due to the multiple job sites spanning more than 20 miles of the highway, all with limited cell phone coverage. However, the CA team provided detailed inspection and documentation, enforced SWPPP requirements, prepared pay estimates, performed submittal reviews, and kept the public informed throughout construction.
This project also had challenges with differing site conditions, archaeological discoveries, adverse weather, and timely completion of the work. HDL provided expertise and facilitated collaboration while finding solutions to overcome these challenges. HDL provided prompt responses and documentation for each change order, which minimized additional costs and reduced delays. During weekly progress meetings, HDL held the contractor accountable for meeting the project schedule and completion date.
