REPLACE HOUSING UNITS at OLD APRA PHASE 2
Scope of Work
This design-build project involved the demolition of 72 existing military family housing units and construction of 59 new housing units.
The work included the abatement of asbestos-containing materials, lead-based paint, and removal of chlordane-contaminated soil under the building pad and the ground around the housing units. Part of the scope of work for the new construction was the building of structural concrete shells, architectural finishes, garage doors, patio, new electrical systems, and mechanical and plumbing and exterior finish systems. The new housing units are located in a sloped part of the area so protection of the environment was considered an important factor during the demolition and removal of contaminated soil.
Because this was a design-build project, we were challenged to submit all the required materials on time for NAVFAC approval before we could begin construction. Even after the designs were approved, coordination was key, as there was another construction company working on phase one of this project and, once that phase was completed in May of 2009, our working sites had newly occupied units near it. To reduce impact on these units, we strove to control traffic flow, dust and noise, and mud on the roadway during construction.
Furthermore, the existence of toxic materials on-site and the slope of the area where the new housing units were located meant that we needed to address the possibility of erosion and flow of contaminated water to existing streams. To handle this, we ensured that there was environmental protection and contractor compliance with the local and federal regulations pertaining to water, air, soil, waste, and other forms of pollution and that control of dust during the dry season and of sediment flow of contaminated rain water during rainy season was properly maintained during construction.
With meticulous planning and commitment to safety, Core Tech rose to meet the challenges above and successfully completed this project within the construction period.
