The project consisted of the construction of the new Federal Aviation Administration (FAA) South Airport Traffic Control Tower (SATCT) Facility. The SATCT Facility consists of a Base Building, Tower Shaft, and Control Cab. The Facility also includes a landscaped and secured site with a dedicated parking lot.

The Base Building is approximately 10,000 square foot building. The Tower Shaft is 12 levels with a 440 square foot Control Cab on the 13th level and is approximately 209 feet above ground level. The Base Building consists of shallow foundations with a cast in place concrete superstructure enclosed with an aluminum metal panel system and aluminum curtainwall system. The Base Building includes the installation of a vegetative roof system. The Tower Shaft consists of a mat foundation with the cast in place concrete superstructure enclosed with an aluminum curtain wall system at the stairwells. The Control Cab consists of a structural steel support system enclosed with an aluminum metal panel system and laminated glass.

In addition, the project includes a connection to utilities, paving of the parking lot, site fencing, and landscaping. Some site, utility, and fiber optic cable installation work will be within the AOA.

The project includes the utilization of Building Information Modeling (BIM) using Autodesk Revit and Autodesk Navisworks

Services Provided

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.
