PESC staff provides on-site construction inspection, submittal review, and solutions to contractors’ specific requests (checking existing structures for construction loading, retrofit detailing, etc). PESC is TxDOT pre-certified in Roadway Construction Management and Inspection (11.1.1) and Major Bridge Construction Management and Inspection (11.2.1).
US290E Manor Expressway – PESC provided construction phase services for the $53M Direct Connect flyover interchange at US 183 and US 290 and 1.4-mile stretch of Expressway between US 183 and Chimney Hill Blvd.
IH 35 Reconstruction Sections 1B and 1C CEI – Under a 3-year contract, PESC is currently providing on-site personnel for the Construction Engineering and Inspection of the reconstruction of IH 35 between Salado and Belton. On site inspection engineers ensure quality and oversee contractors’ operations in the construction of all features of the project: MSE and cut walls, bridges, culverts, drainage structures, temporary shoring, riprap, trenching, etc.
Luminant Mine Haul Road Bridge – PESC designed the 4–span, 160 foot long bridge over Dry Creek to accommodate two side-by-side haul vehicles (each with total loaded weight of 325 tons). The bridge was also designed to support a Mommoet transporter carrying a drag line with a maximum gross weight of 7,800 tons. The 79 foot wide superstructure is composed of tightly spaced Tx54 prestressed concrete girders and a 14-inch cast-in-place concrete deck overlaid with a layer of limestone road base. PESC also provided Construction Phase services including the review of shop drawings, on-site inspection of prestressed girder fabrication at the precast plant, on-site inspection of bridge construction, and preparation of final As-Built drawings.
SH130 Toll Road – Crane Placement at MSE Walls – PESC evaluated contractor’s proposed crane locations behind MSE walls and lifting sequence for setting prestressed concrete girders at adjacent bridges. PESC determined the moving and stationary bearing pressures applied by each crane; performed analyses to check global stability of the walls; and defined each cranes’ limited travel area behind the walls to prevent distress of the walls during lifting.
