Project overview
Vanir was selected by the General Services Administration (GSA) to provide construction management services for Phase I of the expansion and modernization of the Mariposa Land Port of Entry (LPOE), located on 56 acres. Vanir provided limited preconstruction services for the complete project and construction management services for Phase I.
Phase I included:
- Import of 650,000 cubic yards of soil, compaction and grading
- Selective demolition of existing buildings and infrastructure
- Construction of mechanically stabilized earth and reinforced concrete retaining walls
- Installation of miles of utilities, including storm and sanitary sewers, domestic water, gas, electric, telecom and security infrastructure
- Construction of roadways and parking lots
As an extension of GSA’s staff, Vanir maintained a full-time, on-site presence, carrying out all contractual functions in accordance with GSA requirements and the federal acquisitions regulations. We incorporated measures to avoid claims, determine quality and identify ambiguities/conflicts in the project documents.
Successful construction while LPOE was operating
The Mariposa LPOE is the largest commercial port of entry in Arizona. At the time of this project, 50% of produce imports entered the U.S. through the port and additional daily traffic included about 1,000 pedestrians, 1,800 cars and 1,000 to 1,600 trucks. The port was open from 6 a.m. to 10 p.m. and the challenge was to keep port operations uninterrupted throughout construction.
