Submitted by Alder Construction Co. The South Valley Water Reclamation Facility’s Project 4C increased the facility’s average water flow from 38 million gal. per day to 48 million gal. per day, added structures to the campus and was completed while the current wastewater plant was online. Related Links: Intermountain Best of 2009 Project 4C consisted of many different complicated structures. The main structure houses a 6.6-million-gal., cast-in-place concrete aeration basin. Aside from the concrete work, a complicated array of mechanical components, such as sluice and slide gates, floating mixers, an electrical control room, splitter box with galvanized flumes and a
Submitted by Sahara Inc. This project consists of five new core-and-shell buildings for future retail and office tenant build-outs totaling 66,000 sq ft. The building materials are somewhat unique to Salt Lake Valley construction. The use of raw materials was common throughout the five buildings. Some of the materials are polished, clear-coated structural steel, unprimed structural steel, Corten corrugated panels installed flat in some areas and shingled in others.

Submitted by Geneva Rock Products Inc. This 10.2-mile highway project used the design-build process to accelerate the construction of a once-rural farm road that now carries 16,000 vehicles per day because of massive unanticipated growth in the area. Related Links: Intermountain Best of 2009 The major items of work included project design, acquisition of 220 right-of-way parcels, widening the existing road to two lanes in each direction, adding a center turn lane, bike lanes, two million sq ft of full-depth reclamation of the existing pavement, 55,000 ft of storm drain, 570,000 tons of imported aggregates, 220,000 tons of asphalt, three
Submitted by Ames Construction Inc. This project replaced two highway bridges using a technique called accelerated bridge construction, which utilizes precast concrete abutments and precast concrete deck panels. It also widened one mile of roadway and demolished an existing bridge. Related Links: Intermountain Best of 2009 This is the first bridge construction project in Utah to employ accelerated bridge construction. The two bridges were both built using precast concrete elements for the abutments, beam girders and deck panels. Because prefabrication of these elements could be accomplished in a controlled, offsite environment without jobsite limitations, constructability was improved, quality increased, costs
Submitted by Ames Construction Inc. The design-build of this 36-mile-long railroad spur included construction of five bridges. Under an aggressive schedule, crews moved 9.6 million cu yd of earthwork in nine months. The project included onsite processing of 382,000 cu yd of material for production of sub-ballast. Related Links: Intermountain Best of 2009 The bridges are all three-span structures utilizing precast concrete girders and cast-in-place footings, piers, abutments and decks.
