Benchmark Service: Pavement Construction Phase Services
Issue:
The project involved the installation of new reinforced concrete pavement and curb and gutter replacement at a client site to address deteriorated concrete and asphalt pavements. The project encompassed approximately 892 square yards of new 5-inch and 6-inch thick concrete pavements. Benchmark was tasked with providing construction observation and inspection services to ensure adherence to the bid plans and specifications while tracking and managing project costs.
During construction, the client identified additional areas requiring reconstruction in preparation for future site expansion. This additional scope required careful documentation and cost management to ensure the project remained within budget.
Solution: Benchmark worked closely with the client to incorporate the additional work into the existing project. The Benchmark consultant ensured that these changes were meticulously documented and aligned with the bid specifications and unit prices to maintain cost control.
Utility Area Upgrades
The original project scope included a utility area designed for excavation and repaving with reinforced concrete. The team removed asphalt by hand to avoid damaging buried utility lines. After removal, the existing stone base was checked for stability and fine-graded to accept the new concrete. Steel reinforcement (wire mesh placed on support chairs) was installed on the asphalt or stone base before installation of the concrete, reinforcing the structure for long-term durability.
Sidewalk Reconstruction and Drainage Enhancements
Benchmark oversaw the replacement of a concrete sidewalk located in a complex area between a building and driveway. The design was modified to improve drainage by installing a trench drain to replace the two ineffective area drains. A vertical curb was added along the walkway's edge, ensuring safer pedestrian access by separating the sidewalk from the driveway.
Impact: The client added approximately $40,000 of additional work items during construction, which Benchmark’s staff consultant successfully tracked and completed the work per the specifications and at the bid unit prices. This detailed cost-tracking approach provided seamless integration of field changes into the future construction schedule.
Enhanced Site Functionality and Longevity
Field changes included drainage improvements to reduce water pooling, extend pavement life, and reduce maintenance needs over time. These enhancements, coupled with the addition of curbs and gutters, facilitate better stormwater management and create a safer travel zone for pedestrians.
Reliability Improvements
Through meticulous construction observation, expert problem-solving, and proactive tracking of field changes, Benchmark has delivered significant value while ensuring the project meets and exceeds client expectations. By integrating improvements into the current project and planning ahead for future work, Benchmark helped the client achieve efficient, reliable, and durable infrastructure solutions tailored to their needs.
