Alternative Project Delivery Method

Construction Manager at Risk (CM@R), Job Order Contracting (JOC), and Design-Build

Vastco has partnered with owner agencies on several CMAR projects from design through construction. Successful partnerships with local agencies — such as FHWA, ADOT, Coconino County, and the City of Flagstaff — have resulted in award-winning improvement projects that were completed on time and on budget, while maintaining a safe work zone for the travelling public. Vastco has provided northern Arizona with some of the most successful construction projects in recent years.

Cordes Junction

Cordes Junction - SR 69 & I-17 Interchange

This CMAR project consisted of the design and construction of interchange improvements to the existing Cordes Junction Traffic Interchange (I-17 / SR 89 TI). This $51 million reconstruction of an existing traffic interchange between SR-69 and Interstate-17. The project included 3 post-tension box girder bridges, 4 precast AASHTO girder bridges, demolition of 3 existing bridges, complex phasing and detour construction, new roadway construction, existing roadway realignment, drainage improvements, major electrical improvements, traffic control and related work.


Cedar Avenue Pedestrian BridgePedestrian Bridge

The Cedar Avenue Pedestrian and Bicycle Bridge is a skewed-arch, post-tension bridge which incorporates naturally-occurring materials and an unobtrusive visual aesthetic to blend the structure with the Flagstaff mountain viewshed. As part of the CM@R process, Vastco staff worked with the design team to create a constructable design which exceeded City of Flagstaff expectations. The results of this close work with the client garnered the Cedar Avenue Bridge a Southwest Contractor Magazine Best of 2007 Concrete Project Award.
