Runway/Taxiway Reconstruction

Completed Projects

Lambert- St. Louis International Airport

In 2005 the first of a three-phase expansion project was underway; the $10 million taxiway reconstruction was completed in 2006. The project constructed a new, 9,000-foot runway that allows for simultaneous landings and fewer flight delays in inclement weather. ACOT provided:

Construction Management
Quality Control
Field Inspection
Materials Testing
Airfield Lighting

The quality control function involved identification, investigation, and remediation of several significant quality control problems – including cracking from hindered set concrete, clay inclusions in portions of the pavement and improper dowel bar insertion.

Master Plan Supplement

Lambert-St. Louis International Airport Expansion

Preparation of a master plan for new runways, taxiways, aprons, terminal expansion and other improvements expected to cost $1.5B. Responsible for cost estimating, scheduling, environmental impact assessment, and preparation of preliminary designs and site evaluations. As part of our preliminary engineering work for this study, we developed concept designs for runway and taxiway bridges. These bridges, developed under the F-4 preferred design alternative, were designed to span a related section of Lindbergh Boulevard. Under the “Hyland” design alternative, a runway safety area bridge extension was identified on the east side of the airport over I-170.

East Terminal Expansion

Lambert-St. Louis International Airport

Design of airside pavements for expansion of the East Terminal and Concourse. This part of the expansion represented a $10M investment – part of the $70M program and developed a detailed cost estimate for the $46.5M terminal expansion. Project completed on time and within budget.

Bridges & Tunnels

Julian Bridge

Completed Project

University City – St. Louis, MO

ACOT completed the final design of the Julian Avenue bridge replacement. This project consisted of a two-lane, pre-cast concrete, single span bridge in an urban residential neighborhood. The various services provided by ACOT included: original site survey, HEC-2 hydrologic analysis, FEMA “no rise” certification, U.S. Army Corps of Engineers 404 Permit, Missouri Department of Natural Resources 401 Permit and Cultural Survey report, design variance issue resolution, borings and geotechnical investigation report, right of way plans, preliminary and final cost estimate and final plans and specifications maintaining historic stone buttress walls – single span prestressed concrete planks.

All necessary routine design elements were provided including Missouri Department of Transportation and St. Louis County Highway Department standards, utility modifications, scour minimization, traffic control measures, construction easements and repairs to the private property, and contract boilerplate documents and special provisions. In addition, ACOT responded to community aesthetics with a custom, TL-2 rated guardrail design at minimal additional cost.

Construction Services

Arts & Science Building

Completed Projects

Washington University

St. Louis, MO – Washington University

The Laboratory Science Building is a 40,000 Sq. Ft., four-story building and Mechanical Penthouse. The structure was erected using reinforced concrete, concrete beams, steel and encased with decorative brick, stone, and wood to match the existing campus. The facility was placed between two existing buildings with a tunnel connecting the all three.

The building houses laboratories, lecture halls, and study areas. The installation of the building involved excavating and removing an existing parking lot to three stories down. Steel and wood shoring was used to provide support for the surrounding earth walls before installation of concrete footings and foundation could take place. The laboratories and lecture halls are all equipped with state of the art electronics, audio and visual displays and computer equipment.

ACOT’s duties were to allocate a full-time field manager to execute the day-to-day project management for the construction of the facility and provide mechanical and electrical engineers to perform weekly inspections on mechanical, electrical, plumbing and fire protection equipment and systems.
