Project Description

Supported construction of new 100 mW Cogeneration facility and capital improvements to the Central Heating and Refrigeration Plant, (CHRP). Provided design/build project delivery for all off-site interconnection systems and client Mechanical Equipment Rooms retrofits to accommodate the new cogeneration system. Work included design and construction of a new thermal distribution system in the airport Central Terminal Area, to supply nine (9) terminal buildings and all associated engineering design and construction to accommodate Mechanical Equipment Room upgrades to support that system in those independently operated facilities. Design and construction of 1.5 miles of 1,000 PSIG MAOP primary natural gas pipeline, 3 miles of 138 kV underground electrical transmission lines and secondary (double containment) jet fuel pipeline. Significant portion of work occurred in sensitive and secure areas (secure cargo areas, airside working areas (taxiways, runways, buildings) throughout the facility without disruption of ongoing airline operations. Services provided included oversight of engineering design document development, Client approval of materials, specification, schedule, coordination with airport operations, shop drawing review and procurement quality control for all capital improvements. Bid preparation, solicitation, evaluation and award of construction, equipment, and material contracts. Construction inspection, quality assurance, budget and schedule forecasting and reporting to all project stakeholders. Reviewed and approved payments of invoices and managed the change order process. Managed the testing, commissioning and startup services for pipelines and all installed components of the project. Project closeout and managed the turnover to Operations with all final as-built documentation and supported warranty management.

Construction

Specific Techniques/Unique Methods: Schedule was closely monitored by a full-time on-site project administration team with daily oversight and weekly updates. Project utilized medium temperature water distribution system to supply Central Terminal Area for conservation and energy efficiency measures and to replace the aging high temperature system that had reached its useful life. Natural gas pipeline installation utilized HDD installation under two (2) active taxiways during on-going airport operations. Responsible for 138 kV underground electric transmission line to deliver power to the local utility grid.

Superior construction quality was assured for pipelines constructed with comprehensive field oversight and inspection, 100 percent radiographic examination of welded joints and witnessed hydrostatic testing of components.

Drawings and Documentation

Directed subconsultants for the design, development and approval of all necessary engineering drawings and specifications required for the project. Coordinated review and acceptance of shop drawings. Directed all project correspondence and cataloged same. Provided and certified project as-built information and operations and maintenance manuals.

Owner received turnkey installation to supply all necessary remote utilities to the new CHRP and Cogeneration facility. Owner was insulated from all unnecessary contact and coordination and operational issues with secondary clients in the Central Terminal Area and was able to provide singular focus on centralized powerplant capital improvements.
