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.

84 Unit Housing Development

Completed Projects

Central City Development

East St. Louis, IL – Central City

This project consisted of the development of affordable housing units in an area bounded by Bowman Avenue, Exchange, 13th Street, and 15th Avenue in East St. Louis, Illinois. The development was initiated to stem the rapid exodus from the City. The City, through creative financing, a partnership with private sectors, and the banking industry, initiated a scheme to demolish and redevelop abandoned buildings within certain depressed subdivisions in the City.

ACOT was contracted as a subconsultant to assist in the design and project management of the 84 housing units in East St. Louis Illinois. ACOT’s scope of services included, but was not limited to, the design of the internal roads, surrounding streets, water site drainage, lighting, and cost estimating. During the construction phase, ACOT partnered in the oversight inspection and reviewed payment applications and coordinated the utility relocation.



Port of East Saint Louis

Current Projects

The City of East St. Louis is working in conjunction with the current Land Owner to develop a world-class inland river port facility to position East St. Louis, Illinois as a major distribution hub in the United States. The site is approximately 200 acres of undeveloped riverfront.

Rail & Transit

Chicago Transit Authority

Completed Projects

Red Line and Brown Line Improvement Projects

Chicago, IL

Red Line Improvement Project

ACOT served as an extension of the construction management team, with Turner Construction, for the Red Line Improvement Project. ACOT’s responsibilities on the project included cost estimating, inspection, and on-site construction project administration.

Brown Line Expansion Project

ACOT served as an extension of the construction management team with Consoer, Townsend & Envirodyne Engineers, Inc. for the $375M of improvements to the Brown Line. ACOT’s responsibilities on the project included cost estimating, structural field inspection, and on-site construction project administration.

Roads, Streets & Highways

1st & 2nd Streets Improvements (The Landing), Saint Louis Missouri

Current Projects

This project involves the complete demolition and reconstruction of the streets and sidewalks on both N 1st Street and N 2nd Street from Washington Avenue to Morgan Street and face of building to face of the building. Per Historic requirements, the Cobblestone Street will need to be removed and re-used in the original pattern. Construction phasing will be required to allow the businesses to have continued access to their front doors during business hours. Sidewalks will most likely be poured in colored and stamped concrete rather than pavers due to the poor performance of the existing pavers.

All Utilities in the corridor will be reconstructed to minimize the need to tear up the new street in the future. Water and Sewage will be included in our bid documents as the project budget includes reconstructing those Utilities. Existing Light poles, Benches, Trash Can holders, etc. will be removed and re-used. The intersections will be redone using the existing cobblestone as much as possible and will likely include concrete bands and pavers. Arcturis will take the lead on this hardscape design aspect.
