Progressive infrastructure planning to ensure the sustainability project – or pipes – is an initiative led by the city of Tampa to address its aging underground infrastructure. As part of the Tampa 20 -year -old capital improvement program, of $ 2.9 billion, the largest in the city’s history, the project aims at critical updates to four neighborhoods.
The project was aimed at the lines of services over 80 years old, restores service access and reduces maintenance costs and failure risks. The improvements were oriented from the infrastructure, age, location and emergency repairs.
Through a gradual design approach, the project integrates an extensive main replacement of water, the health rehabilitation of sewers and the improvements of the stormwater system. More than 24 kilometers of health sewerage and 18 kilometers of the main water are rehabilitated, replaced or increased, largely through trenches without trenches that minimize the interruption of residents and street traffic.
During the project development phase, Kiewit collaborated with five departments in the city of Tampa (water, wastewater, transport, stormwater and public dissemination) to define the scope, develop the basis of the design report and perfect the prices of the project. Each department had different priorities, but through directed individual meetings, the team achieved a complete alignment.

The crews worked in dense residential areas where limited access, existing uses and private property functions restrict construction. The team mitigated potential problems by planning work with minimal disruption, restoring all affected functions and using trench without trenches, such as the gust and the cured coating in the site, for more than 90% of the substitutions. Trenche -free construction methods allowed new pipes to be installed inside the existing alignments with minimum excavation, significantly reducing noise, dust and traffic interruptions for residents. Not only did the approach retain the aesthetics of the neighborhood and mature trees, but also reduced construction deadlines and minimized restoration costs.
The work was also performed under active routes of the CSX railway. Through a wide pre-construction coordination, the team successfully completed seven Jack-And-Bane facilities, maintaining uninterrupted railway operations. In areas where Jack-And-Baby was not feasible due to service conflicts, Kiewit proposed and executed the first Tampa installation of the compression HDPE pipe coating. The solution was approved by the city and could report future infrastructure updates.

To streamline delivery, the project implemented a refined utility mitigation protocol, improving the 6 -foot standard utility window to a 3 -foot area. Increased accuracy allowed the field equipment to proactively adjust the alignments, eliminating most of the larger utility transfers and the associated programming risks.
Minimizing the interruptions of neighborhood residents was essential. A wide public dissemination and coordination with residents, public services, railways and permitted agencies guaranteed transparency and efficiency throughout the birth.
Despite the complexity of the project, all construction packages were delivered earlier than expected and the budget.
