PS 2 was constructed in 1973 with periodic updates through the years. Many original components remain and some of the subsequent upgrades are nearing the end of their service life. The purpose of this project is to modernize the facility with energy efficient systems designed to improve reliability and reduce the operations and maintenance (O&M) effort, while meeting wastewater flow demands for the next 20 years.

CRW worked with the ARRC to upgrade Depot Drive, located west of the Historic Railroad Depot, from a previously gravel, undefined “roadway” to a paved facility with curbs, sidewalks, landscaping, lighting, drainage, and connectivity to nearby development. Improvements were designed to allow for future development of roads and trails within the Ship Creek area while minimizing and discouraging the existing trespass issue onto ARRC active tracks. This project was completed in 2024.

CRW provided project management, design, and construction support services for the design of the 82nd Avenue lift station. CRW services included hydrologic modeling, drainage analysis, lift station plan and section design, structural details, and lift station power and controls. This project used alternative pump sizing techniques with a large storm event overflow pipe to construct a system that was more efficient to construct and operate. CRW provided storm drain pump station design using Municipality of Anchorage (MOA) design criteria and working with MOA to find an efficient and cost effective design.

Design of a replacement stormwater lift station, controls, and force main in West Anchorage, replacing a 30 year old existing storm drain lift station. This project included public involvement, survey, and easement acquisition.

The Chester Creek culvert underneath Northern Lights Blvd failed during the winter of 2020. As a fast paced, emergency repair project, CRW provided design for long-term replacement. Some of the services performed were hydraulic analysis, permitting and environmental impact analysis, flood hazard analysis, stream realignment, rip rap, fish habitat permitting, traffic control analysis, utility impact analysis, relocation of the water main which runs below the culvert, and plans, specifications, and cost estimate. Construction was completed during the allowed fish window. The high-power, overhead electric transmission lines were able to remain in place during construction, saving both time and money.

CRW provided survey, geotechnical, and civil design on this design-build project that involved construction of a 149,000 sf, multi-story warehouse on a 9 acre lot. Medline provides medical products for many of the hospitals and medical offices in the state. The new warehouse will include 20+ truck loading docks, parking for 100 vehicles, and additional trailer parking. Design consisted of detailed geotechnical analysis for site development, foundation design, and pavements (asphalt and concrete). CRW’s geotechnical scope included a detailed liquefaction assessment and long term groundwater monitoring.
Location: Anchorage, AK
CRW provided civil and structural design for a new 20,000 sf aviation hangar and a 9,000 sf weather shelter hangar. Design challenges included extension of poorly documented water and sewer services, reconfiguration of plane parking tie-downs, and using vegetated bioswales to treat storm runoff.

For this multi-phase renovation project CRW provided mechanical and electrical design and construction administration services to upgrade the roof and piping systems. CRW provided a new displacement ventilation system design for the multipurpose room and the gymnasium, as well as hydronic system upgrades.
Location: Anchorage, AK
CRW provided geotechnical support throughout the investigation and design of building and apron repairs due to the November 2018 Alaska magnitude 7.1 earthquake. CRW’s efforts started with desktop research of existing geotechnical conditions followed by a geotechnical investigation to assess the apron and building’s stem wall sink hole conditions. The design consisted of a new apron section and mechanically stabilized earth (MSE) retaining wall for the stem wall. CRW provided on-site inspection during construction of the earthwork, retaining wall installation, and paving operation.
