Taxiway E Reconstruction
Centrally located in the heart of the airfield at Salt Lake City International Airport, Taxiway E is one of two primary taxiw ays that connects the east and west sides of the airfield. Taxiway E also provides access to and from the midfield Terminal complex and the newly opened Concourse B. The taxiway is an essential component of the airfield network and plays a critical role for aircraft operations at the Airport. Last reconstructed in 1996, it has been subjected to 25 years of both heavy traffic and chemical deicing agents. The Portland Cement Concrete pavement of Taxiway E had reached the end of its useful life and was in need of a full reconstruct.
The project consisted of reconstructing approximately 20,900 square yards of Portland Cement Concrete pavement in accordance with Federal Aviation Administration standards. Due to its central location and proximity to the terminal, a complex phasing plan was required to maintain continuous access to the terminal and minimize impacts to daily aircraft operations while maximizing the efficiency of construction and maintaining a safe working environment for construction crews and aircraft in the area.
The scope of the project included removing the existing pavement section of Taxiway E and constructing a new pavement section consisting of 16 inches of Portland Cement Concrete Pavement (P-501) on 6 inches of Lean Concrete Base Course (P-306) on 12 inches of Subbase Course (P-154). The nearly 13,000 cubic yards of old concrete material was kept on site, crushed and recycled as part of another airport project, keeping it out of local landfills. Additionally, the project included asphalt shoulder paving, utility adjustments, and the installation of a state-of-the-art LED airfield lighting system.
In accordance with the Salt Lake City Department of Airports master plan, a section of a future connecting taxiway was constructed to alleviate congestion as the airport continues to expand. By constructing this partial taxiway connector, the rest of the taxiway can be constructed in the future without the need to close Taxiway E.
With an awarded project value of approximately $6.8 million, Ames Construction and their subcontractors had 150 calendar days to complete the project. Although the project was challenging, the team of Salt Lake City Department of Airports, Ames Construction and their subcontractors, along with the design team of Jviation and Lean Engineering worked diligently to deliver this project on time and under budget.

Tyson Case Ready Plant
Acme was hired to complete the site concrete for the new Tyson Foods processing facility in Eagle Mountain, Utah. The project included over 200000 SF of concrete paving and flatwork and just under 6 miles of curb. Work on this project began just as the world was shutting down due to COVID-19. After being considered a critical project for food delivery by the government, we accelerated our schedule and dedicated manpower to complete the project in 75% of the originally scheduled time. Due to the remote location of the facility, special accommodations needed to be made for concrete delivery. Despite challenges due to COVID-19, Acme’s portion of the project was completed ahead of schedule and within the original budget.

I-15 Technology Corridor
The I-15; Lehi Main to S.R. 92, Technology Corridor (Tech Corridor) project widened and reconstructed this section of I-15 to address rapid growth in the area over the last decade. This was the last section of I-15 to be widened between Bangerter Highway in Salt Lake County and Spanish Fork in Utah County, and its completion reduced traffic congestion on I-15 and on nearby surface streets and interchanges. In addition to widening 4.4 miles of I-15 to six lanes in each direction between S.R. 92 and Lehi Main Street with Portland cement concrete pavement (PCCP), the project scope included two full interchange redesigns at S.R. 92 and 2100 North, a one-way frontage road system between the two interchanges, 15 bridge replacements, a new Triumph Boulevard bridge over I-15, a new flyover ramp at 2100 North, and active transportation trails. The Utah Department of Transportation (UDOT) specified the use of PCCP on I-15 mainline, ramps, and the Timpanogos Highway interchange because they desired a durable, long-lasting pavement to carry the heavy truck traffic for decades to come, with I-15 reaching a projected volume of 215,000 annual average daily traffic (AADT). Additionally, the Design-Build delivery method gave the Ames-Wadsworth joint venture (A-W) flexibility to optimize the design and construction of the pavement section, which resulted in cost and time savings and improved quality and long-term performance of the PCCP.
Congratulations to all the award-winning projects and teams!!
We look forward to seeing everyone next year at the annual URMCA Concrete Paving Workshop
