Repair Taxiway, Offutt AFB, NE
For this $6.6M project conducted for the Air Force Civil Engineer Support Agency (AFCESA), EQM was the prime contractor for 2 major runway repair projects at Offutt AFB: the Taxiway Papa Run-up Area repair project and the Taxiway Charlie repair project. EQM also executed 4 other S/R&M building renovation and modernization projects at Offutt AFB concurrently with the taxiway work.
Daily tailgate safety meetings were held with all subcontractor personnel. Our site construction manager had daily communications with Base Operations and Security Forces to coordinate security access to the site.
EQM held weekly onsite status and progress meetings for the duration of the project. Attendance at meetings included the project COR, Base Security, Base Airfield Operations, the E-4 mission commanders, both prime and subcontract field and project construction managers, and the EQM project manager. These taxiway repair projects involved removal and replacement of a significant portion of Taxiway Charlie and Papa Run-up Area at Offutt AFB.
EQM developed a concrete mix design and conducted preconstruction testing and analysis in accordance with stringent USACE airfield concrete specifications. Upon acceptance of the concrete mix design, EQM was responsible for the demolition and disposal; excavation; sub-grade preparation; placement of pavement underdrains; installation of rapid drainage base aggregate course; placement of approximately 7,000 CY of 6,500 PSI Portland cement concrete pavement; asphalt shoulder replacement; airfield pavement markings; construction; removal and restoration of 2,000 feet of a temporary construction access road; security fencing modifications; and installation and maintenance of airfield low-profile barricades. This airfield is a restricted and controlled area and required extensive coordination with Base Operations and Security Forces and required full-time security escorts.
