Project Value N/A

Since 2015, Hill has provided construction management and inspection (CMI) services to the Maryland Aviation Administration (MAA) for two consecutive indefinite delivery/indefinite quantity (IDIQ) contracts. Work has involved a variety of airside, landside, and terminal projects encompassing terminal life safety systems, road widening, code compliance, and other infrastructure repairs at Baltimore/Washington Thurgood Marshall Airport (BWI) and Martin State Airport (MTN).

Over the years, the Hill team has developed strong working relationships throughout the MAA organization and leverages these relationships to drive effective coordination and facilitate project delivery. The team has also internalized the processes, procedures, and standards governing the MAA’s construction programs. This includes a commitment to partnering with numerous local small and disadvantaged business enterprises on every task order to which Hill is assigned. Specific task orders have included:

BWI D-E Connector and Security Checkpoint: As a subconsultant, Hill provided inspection support for the construction of the D-E Connector and Security Checkpoint project at BWI.

Work included the construction of a secure connection between the existing D Pier and the existing E Pier to allow circulation between the two piers without the need to pass in and out of security checkpoints. Throughout construction, Hill provided full-time, detailed inspection of civil, mechanical, structural, welding, and architectural work to verify quality workmanship in conformance with contract requirements. Hill also checked materials, equipment, and labor entering the work site for contract compliance; calculated quantities; inspected on-site materials; monitored plant testing, sampling, and materials testing; attended all meetings; and verified construction as-builts and quantities.

BWI Mathison Way Resurfacing: Hill served as the owner’s construction manager and procurement officer’s authorized representative for the asphalt pavement rehabilitation of Mathison Way, a crucial road serving BWI’s cargo tenants and Fire Department. The scope also entailed the addition of topsoil and stabilization of shoulders along Mathison Way to meet state requirements. Due to the road’s location, constant coordination with BWI Air Rescue and Fire Fighting, airport operations, and other contractors working on the cargo building was necessary to complete the work on time.

Hill provided overall oversight and project coordination, including schedule, budget, and change management; document control; staff oversight; client relations; and closeout services. Hill also helped coordinate between stakeholders to maintain traffic access throughout the project. This was crucial when the contractor on an adjacent project hit an existing water line, which impacted a section of Mathison Way. While this issue affected completion of final striping and removal of traffic control devices, Hill’s efforts helped maintain traffic access. Ultimately, Hill’s support contributed to on-time completion and $225,419 in savings for the client. Because of the team’s success, the Maryland Quality Initiative (MdQI) recognized the Mathison Way Resurfacing project with a 2020 Award of Excellence in the category of Modal Awards – Projects Under $5 Million.

BWI Taxiway Bravo Reconstruction: As a subconsultant, Hill provided inspection support for the reconstruction of Taxiway Bravo at BWI. The scope comprised bituminous concrete pavement demolition, excavation, erosion and sediment control measures; installation of a new Portland cement concrete pavement, a new bituminous concrete pavement, and a new shoulder pavement; mill and overlay of existing asphalt pavement; and the removal and installation of taxiway centerline, pavement markings, edge lights, and airfield signage. Hill provided full-time, detailed inspection of construction work to help ensure quality in conformance with contract requirements throughout construction. Hill also checked materials, equipment, and labor entering the work site to confirm contract compliance; calculated quantities; inspected on-site materials; monitored plant testing, sampling and materials testing; attended all meetings; and verified construction as-builts and quantities.

Terminal C Lower Level Loading Dock Renovations: Hill provided design review and on-site construction management for the $250,000 renovation of an existing loading dock at the lower level of Terminal C at BWI to convert it into storage space. The work involved structural, architectural, mechanical, electrical, plumbing, and fire protection trades. Because the project took place in an operational terminal, the project team had to carefully plan and coordinate with a variety of authorities having jurisdiction, including the MAA’s landside operations and Maintenance, Fire, and Security Divisions. The team also had to coordinate with several airport tenants impacted by the work. Hill helped drive effective coordination, facilitating the relocation of tenant equipment and materials and the rerouting of traffic flow around the work area.

DX/DY Terminal HVAC Upgrades: Hill provided a full suite of CMI services for a highly visible HVAC replacement project in two active terminals. With Hill’s management support, the project team installed new rooftop air system units, an upgrade to enable fresh air ventilation and energy reduction, while protecting public traffic in the terminal below. This required comprehensive coordination with a host of airport agencies, including airport operations, the Office of Airport Security, the Office of the Fire Marshal, and terminal concessions representatives. The project team also performed work overnight and around airline flight schedules and restored areas of impact by 4 a.m. each shift. Pre-testing of the units took place off site prior to delivery and installation to save time. Hill helped the team prepare, schedule the work, and expedite work plan approvals, promoting project success and reducing impacts on airport operations.

Baltimore Gas and Electric (BGE) Feeder and Substation Upgrades – Phase 2: The MAA selected Hill to manage a $20 million BGE infrastructure upgrade project. The scope includes replacement of existing 35kV switchgear at the BWI Thurgood Marshall North and South Substations to accommodate new BGE feeders; upgrade of relays and metering for three 15kV switchgear lineups; life safety, security, and HVAC improvements at switchgear locations; switchgear foundations and fencing relocation; and coordination with BGE. Hill is providing construction management and inspection services to help ensure quality, control the budget and schedule, and prevent impacts to airport operations.
