Last month, ACEC California unveiled the 2017 recipients of its prestigious Engineering Excellence Awards. In all, 21 California firms representing 38 projects were named winners. Four Sacramento-area projects were recognized for outstanding achievement, including: the Golden One Center in Sacramento; the Closed Lincoln Landfill Groundwater Corrective Action Project in Lincoln; the Bailey Creek Bridge Replacement Project in Plumas County; and the Riverfront Reconnection Project-Phase I in Sacramento.
Honor Award Winning Projects in the Sacramento area include:
Closed Lincoln Landfill Groundwater Corrective Action Project in Lincoln, CA by Holdrege & Kull Consulting Engineers and Geologists of Chico, CA. The City of Lincoln contracted with Holdrege & Kull as the prime consultant to provide environmental engineering design and construction services that achieved compliance with the California Regional Water Quality Control Board’s Cleanup and Abatement Order. The Order required the groundwater table to be lowered beneath the bottom of the unlined landfill waste material, maintain a minimum 5-foot-separation distance between the bottom of the waste and the underlying groundwater table, and extract the offsite contamination plume. Holdrege & Kull designed a perimeter dewatering trench system that achieved full compliance within 8 months after completing construction versus the estimated 3 year period for compliance. Holdrege & Kull’s value engineering solution saved the City of Lincoln approximately $12,000,000 when compared to a clean closure alternative solution requiring the complete removal and disposal of the waste at a Class I landfill facility.
Golden One Center in Sacramento AECOM of Orange, CA, in association with Henderson Engineering, Inc., Kansas City, MO. The AECOM-designed Golden 1 Center, home of the National Basketball Association’s Sacramento Kings, is the first indoor sports arena in the world to achieve LEED platinum certification. The arena features five-story, aircraft-hangar doors that open to the city and the natural cooling of the Sacramento Delta breeze. A first-of-its-kind displacement ventilation system saves energy and improves comfort by delivering conditioned air directly beneath the seats and allowing fans to influence the temperature through an app on their phones. The 100% solar-electric venue will achieve a 45 percent reduction in water use and 30 percent reduction in energy use of a typical arena. The building has earned the highest score for a sports venue in the LEED program and placed in the top three percent of all LEED certified buildings.
Merit Award Winning Projects in the Sacramento area include:
Bailey Creek Bridge Replacement Project in Plumas County, CA, by WSP | Parsons Brinckerhoff of Sacramento, CA. Built in 1928, the original Bailey Creek Bridge had aged into a state of disrepair and was classified as structurally deficient by the California Department of Transportation. The bridge crosses Bailey Creek on County Road 322A in a remote part of northwest Plumas County. The WSP | Parsons Brinckerhoff team evaluated multiple bridge types, construction methods and bridge erection schemes to reduce the project footprint and minimize construction duration and impacts to the site. The existing three-span bridge was replaced with a precast single-span bridge on the same alignment, implementing a detour on a temporary bridge adjacent to the old structure during construction. This innovative approach saved the County time and costs, met seasonal construction restrictions, met requirements to maintain roadway traffic and eliminated permanent impacts to Bailey Creek.
Riverfront Reconnection Project-Phase I in Sacramento, CA, by WSP | Parsons Brinckerhoff of Sacramento, CA. When I-5 was originally constructed, the highway interrupted the city’s grid system, separating downtown Sacramento from the riverfront area and Old Sacramento, making multimodal travel difficult. The two existing entrances to Old Sacramento were hidden and not easily accessible. The Riverfront Reconnection project provides a new bridge entrance that is accessible to motorists, bicyclists, pedestrians and horse-drawn carriages traveling into Old Sacramento from the Capitol Mall Bridge to 2nd Street and Neasham Circle. Completed ahead of schedule, the project provides green bicycle lanes and safe pedestrian facilities, used aesthetic treatments to blend into the historic area, met seismic safety and Americans with Disabilities Act design standards, mitigated noise and visual impacts, and minimized construction impacts to traffic along I-5. The project also includes provisions to accommodate the City of Sacramento’s future streetcar system.
About the EEA Awards
ACEC California’s annual Engineering Excellence Awards competition recognizes outstanding achievements in engineering and land surveying projects completed by California firms. In 2017, 18 Honor Awards were granted to 12 firms and 20 Merit Awards were granted to 11 firms. An awards dinner, which is a fundraiser for the ACEC California Scholarship Foundation 501(c)3, will be held in San Francisco, February 2, 2017, and Honor Award winning projects will have photographic panels on display at the Capitol, outside of the Governor’s office, in early 2017.
The winner of the Golden State award, signifying the best overall project, will be announced at the awards dinner. Honor Award winners also are eligible to enter the national level Engineering Excellence Awards competition.
