T.Y. Lin International (TYLI) was awarded an Indefinite Delivery/Indefinite Quantity (IDIQ) with the Kwajalein Range Services (KRS), LLC to provide a variety of services in updating facilities and infrastructure on the Island of Kwajalein, Republic of the Marshall Islands, for the U.S. Army Corps of Engineers, Kwajalein Atoll.

Project designs will comprise modifications to existing dining facilities, renovation of transient lodging, structural shoring plans for automotive facilities, assessments of aging facilities and infrastructure, and improvements at the island’s airport facility. TYLI engineers have already traveled to the remote island on multiple occasions to evaluate building structures, heating, ventilation, and air conditioning (HVAC) systems, and architectural elements.

Over the 5-year IDIQ, TYLI will provide a full range of professional engineering services, including Civil, Electrical, Mechanical, and Architectural. Task Orders Services are to include development of Statements of Work for various base requirements, as well as detailed designs drawings and specifications for construction projects.

Project Highlights:

  • Facility inspections and renovations
  • HVAC systems
  • Mechanical, electrical, and plumbing systems
  • Fire protection systems
  • Power plant upgrades


TYLI was awarded the design of the approximately 20,000-square-foot dining facility, which included demolishing the center 6,000 square feet of the masonry structure and replacing it with structural steel, and renovating the remaining 14,000 square feet. Facility improvements included new concrete towers and masonry façade, kitchen, restrooms and crew rooms, bar, two dining rooms, flex dining/banquet room(s), security and intercom systems, HVAC system, and mechanical, electrical, and plumbing systems. Given the facility’s location on a coral atoll less than a half-mile wide, stainless steel, fiberglass reinforced nylon (FRN), and plastic components are used where possible to combat the highly-corrosive effects of coral dust and salt spray on ferrous metals and concrete.


TYLI was selected to inspect, analyze, and develop performance specifications and drawings for interim structural repairs to the 60,000-square-foot lodging, bank, food court, and main exchange building, a three-story reinforced concrete structure built in 1952, in order to extend its useful life for another five to seven years. Following detailed inspection, testing of corroded/dilapidated areas, and field measuring, the structure was modeled to evaluate stresses in critical members and connections and determine the appropriate repair methodology for those members. Performance plans and specifications were developed for all critical members and connections. TYLI was responsible for all engineering services during construction and final inspection of the repairs.


TYLI provided Architecture/Engineering assessments and designs for the fire protection, plumbing, and electrical systems components of the Kwajalein Power Plant (KPP) Facility 994, Fire Pump House Facility 997, Diesel Transfer Pump House Facility 1037, and Seawater Pump House Facility 990. Included in the project were the assessment and redesign of the existing Saltwater Cooling System from Lagoon intake to Lagoon outfall to support ten 4.4 MW engines with two supply lines and two discharge lines. The redesign of the Saltwater Cooling System included removal of the desalination line from KPP to Freshwater Production Facility 855. TYLI’s design eliminated the system’s single point of failure . The firm prepared biddable documents including, but not limited to, plans and specifications.
