Energy & Infrastructure

Flagstaff’s newest transit hub which has a Gold Level Rating from the Coconino County Sustainable Building Program, is only the 2nd CLT/mass timber structure in Arizona.

The 20,938 SF Downtown Connection Center (DCC) will operate as the new operations and office space for Mountain Line, Flagstaff’s transit entity. At completion, the project will include a community room designed to serve the public, lobby and restroom space for bus patrons, and office spaces. The entire building is electric-service only with a design for future photovoltaics.

Once complete, the project will be the second CLT/mass timber project in the state of Arizona and the only in northern Arizona.

Built on an active transit hub and on the corner of two main streets, site safety was top priority. Site safety considerations include complete segregation of construction and transit hub activities, the installation of a temporary driver break room/comfort station outside of the work area, daily coordination with Mountain Line operations regarding ongoing construction activities, and coordination with the City of Flagstaff, APS, Unisource, and ADOT for utility relocation.

Glen Canyon National Recreation Area has their largest wastewater treatment facility located at Wahweap Marina, which pumps sewage to Page crossing the Glen Canyon Bridge at the Colorado River. The sewer force main at this facility hangs off the side of the bridge 800 feet above the water below and was deemed in critical condition. Loven Contracting acted quickly and performed immediate assessments of the pipeline structure upon contract award.

After the pipeline breaches were identified, Loven Contracting developed a scope of work to perform the immediate repairs required to allow the pipeline to function properly. In order to access the pipe and begin the repair process, a bridge truck was utilized to lift personnel out and over the side of the bridge. Using the bridge truck required closure of a travel lane on the bridge, restricting traffic flow. Due to an outstanding traffic permit between ADOT and the local houseboat transportation company, the bridge lanes could not be restricted between the hours of 6am and 8pm. As such, all traffic closures and bridge truck activities were conducted after 8pm.

In addition to our construction services, Loven Contracting provided valuable recommendations and advisement to the National Park Service to ensure the pipeline’s future long-term performance. This project came in below original estimates, providing an overall cost savings to the National Park Service.

High water events in the autumn of 2013 caused significant damage to the Rainbow Bridge Trail in Rainbow Bridge National Monument – a remote National Park Service site accessible only via footpath or by boat.

Repair and reconstruction of the trail required barge transport of all equipment, materials, and personnel from Page, Arizona, to the job site. To reduce transportation costs and job duration, the crew was supplied with houseboat housing, enabling them to maintain a continuous work schedule.

The trail repair and improvement process included trenching and excavating for a new gabion trail support structure and installing the gabion. To address additional erosion caused by an overhead waterfall feature during flash flood events, Loven Contracting designed and constructed a concrete pad in the water flow’s impact zone. Upon construction completion, the crew removed the temporary trail reroute and the equipment access road. Our crew conducted all site clean-up and restoration activities per National Park Service standards.
