Project Highlights

• Salvaged gas pipeline sustainable design solution
• Precast concrete and structural steel systems
• Four bid packages
• Structural lead on preconstruction bidding on behalf of owner

Overview

The primary structural components of this four-story, 450,000 square foot school facility are precast concrete plank and structural steel with steel joists. Lateral force is resisted with vertical diagonal bracing. The building is supported by driven, steel pipe piles and cast-in-place concrete pile caps and grade beams. Portions of the project were surcharged incorporating wick-drain technology to permit the use of a grade supported slab. Abandoned gas pipe from the southern part of the country was salvaged and used as piling for the building, coming to the job site with its cathodic protection system still in place. This material provided a great sustainable solution for the project’s nearly 1,200 piles. Delivery required four bid packages. Since the contractor was not selected until the final bid package, MBJ led the preconstruction bidding period on behalf of the owner.
