This South Airfield area improvement project installed the fixtures and cable to light Runway 10C-28C, including replacement of selected high-speed taxiway centerline light bases.
Other work under this contract included improvements to the Runway 22L Glide Slope facility, drainage improvements at various Runway 28C NAVAID facilities, and improvements to the existing Cargo Tunnel Fan Rooms. Apron spaces were cast, as well, to serve the FedEx and United Cargo facilities.
The work was completed in phases, the first phase of which installed the light fixtures, cable and home run cable, the ductbank over the existing cargo tunnel, the ComEd ductbank and manholes for the future runway status light shelter, and replacement of the selected taxiway centerline light bases. Improvements to the existing 22L glideslope facility followed, as well as improvements to the Runway 28C glideslope, 28C inner marker access roadways, and several light bars along Runway 28C ALSF. Work concluded with improvements to the fans and equipment in the cargo tunnel east and west fan rooms.
Our team provided construction inspection, scheduling, and contract administration for this project—providing services to implement and enforce applicable codes, standards, specifications, policies, and procedures. With a full understanding of the project scope, plans, and specifications, our team also coordinated between the direct project assignment and other active Program assignments.
While preparing for the bidding process, quantities submitted by the project teams were verified before acceptance, and pay estimates were prepared. Pre-bid meetings were held prior to subcontract packages being solicited, and Requests for Information were received and answered.
As contracts were awarded, all required paperwork was collected and reviewed. Paperwork at the start of construction, as well as at monthly payment intervals, included pay estimate submittals, sworn statements, subcontractor payment certification, M/W/DBE status reports, certified payrolls, canvass reports, partial waivers of liens, etc. Contracts, maintained in the CDA Computer Database (Prolog Converge), were set up by our team and administered throughout the project, including Contract Document review for Method of Measurement and Basis of Payment sections.
During construction, the following reports and documentation were prepared and submitted for approval: Resident Engineers’ Field Orders, Proposed Contract Modifications (PCM), Request for Contract Modifications (RCM), Line Item Changes (LIC) Inspectors’ Daily Reports (IDR), Daily Construction Reports (DCR—including non-conformance reports (NCRs) or Quality Deficiency Reports (QDRs)), and Field Orders for Time & Material work. The approvals of all the listed reports, as applicable, were tracked and secured.
Based on updates received during weekly project meetings (including DOA Construction Working Operations Group meetings: CWOG, and Short Term Operations and Phasing: STOP), the resource-loaded, Primavera-based CPM Schedule would be updated and analyzed regularly, comparing contractors’ actual work completed against anticipated milestones and the program master schedule. Continued compliance with sustainable requirements, soil erosion and conservation requirements, safety protocols (including FAA Part 139), the CM Quality Assurance Plan, and other contractual obligations was assured by Construction Inspectors. The ongoing development of as-built documents throughout the project was monitored by our team, as well.
With regard to subcontractor/supplier coordination and invoice/monthly payment request processing, Contractors’ invoices were reviewed for alignment with quantity measurements of units of work completed and compliance with Contract Documents. Any outstanding Requests for Information (RFI), Submittals (processed in hard copy with the FAA and EOR), Requests for Inspection of Materials (RFIM) and mechanics liens were tracked and processed, as well. This information, as well as audit of M/W/DBE utilization/certified payrolls and certificates of insurance, was compiled into the monthly contract close-out as well as the final project close-out documentation. Updates from the Pay Estimates were integrated with the project budgets in order to ensure that actual expenditures tracked with anticipated spending.
