Owner: AK DOT&PF

proHNS is providing a team of experienced Project Engineers, Office Engineers, and Engineering Technicians to provide contract administration and inspection services for this high-profile, logistically challenging road improvement project in downtown Juneau. The 2019 construction season is focusing on the highly trafficked stretch of Egan Drive between Willoughby and Whittier Streets, necessitating complex coordination between stakeholders to facilitate traffic control, plan construction schedules, and keep private citizens and nearby business owners apprised of project developments. When complete, improvements to the area will include new pavement, improved pedestrian and bicycle facilities, new storm drainage collection systems, repaired retaining walls, and more.

Calvary Fellowship Subdivision

Calvary Fellowship Subdivision

Location: Juneau, AK
Project Dates: 2017-2019
Owner: Southeast Endeavors

proHNS designed this 8-lot subdivision on behalf of Southeast Endeavors, and subsequently provided construction inspection services under our three-year CBJ term agreement. Our Lead Designer Lucas Chambers worked on this project from start to finish. Beginning in 2017, Lucas designed and modeled the new road, lot layout, driveways, and water and sewer facilities servicing the new lots. He also designed an extension of the existing ductile iron water main with new HDPE water main to service all lots, with the sewer extending up the new road and tying into the existing system running along Glacier Highway. In 2018, CBJ hired proHNS to ensure subdivision construction abided by all municipal codes and standards. Lucas provided inspection services on this project through its completion in 2019.

Location: Haines, AK
Project Date: 2019
Owner: Haines Borough

proHNS is currently designing three sections of the six-segment Portage Cove Waterfront Trail. The type of site-specific trail improvements will be determined during design and through coordination with Haines Borough representatives, though it is anticipated most of the trails will be constructed of gravel surfacing with limited sections of concrete sidewalk/ramps. Our primary goal is to design safe, usable trail alignments that can be constructed using cost-effective materials and methods, as well as allow for future upgrades and improvements. Services and deliverables provided on this project include topographic survey, base map development, design and analysis of alternative alignments, technical specifications, and construction-ready plan sets.
