T.Y. Lin International (TYLI) provides Architectural/Engineering (A/E) services under an Indefinite Delivery Contract (IDC) with the Department of the Air Force, Charleston Air Force Base (AFB) for projects at Joint Base Charleston - AFB in North Charleston, South Carolina.

A/E services include design and preparation of request for proposal documents for maintenance, repair, alterations, and new construction projects. These projects require architectural and multi-disciplined engineering services for commercial/industrial and residential type facilities, utilities, and pavements.

TYLI has received only “Excellent” Architect-Engineer Contract Administration Support System (ACASS) ratings under this contract.

Project Highlights:

  • Building/facility additions, renovations, and repairs
  • Heating, ventilation, and air conditioning (HVAC) systems
  • Roof repairs
  • High expansion foam system
  • Facilities study
  • Water system and base drainage studies
  • Elevated water tank repairs
  • Water tank recirculation systems

RENOVATION/ADDITION, BUILDINGS 174 AND 184

TYLI designed the comprehensive renovation of a 16,000-square-foot warehouse and a 26,500-square-foot aerial delivery/training facility, including a building addition, new conditioned office space, approach ramping and perimeter roll-up doors, exterior wall systems, and roof. Mechanical renovations comprised new office air conditioning and radiant heat/ventilation in warehouse areas. Fire suppression and extinguisher cabinets and a fire detection and alarm reporting system were also provided.

AIR FREIGHT TERMINAL ROOF REPAIR, BUILDING 178

TYLI performed site investigation and field research for the replacement of the existing built-up Roofing (BUR) system. All work was in accordance with current National Roofing Contractor (NRCA) Standards.

TEDDY CARE WATCH AREA

This project renovated an existing immunization clinic, including waiting area, reception room, bathrooms, and treatment room, into a new Teddy Watch Area for childcare. TYLI conducted a design charrette, prepared programming requirement documentation, identified renovation requirements and provided a cost estimate. The team was also responsible for researching all requirements to establish a childcare facility for up to 10 children, up to 12 years of age.

ELEVATED WATER TANKS #1, #2, AND #3

TYLI inspected three elevated water tanks for asbestos and lead paint, with a secure chain of custody followed for delivery. Each tank was inspected using polarized light microscopy (PLM) methods. A total of 30 samples were evaluated for hazardous materials.

C-17 MAINTENANCE MANAGEMENT FACILITY ROOF REPAIR, BUILDING 59

TYLI’s design replaced all hips, valleys, mechanical vents, and vent through roof (VTR) flashings in designated areas. A redesign of the roof layout and slope was also necessary in specific locations to simplify slopes and details and preclude future problems.

HIGH EXPANSION FOAM SYSTEM ADDITION, BUILDINGS 532, 570, AND 700

TYLI’s design replaced the existing deluge system with a dry pipe closed head system. The entire fire detection and suppression system was designed to meet current requirements.

TRANSPORTATION WORKING CAPITAL FUNDS FACILITIES (TWCF) STUDY

TYLI visually assessed the current condition of 25 TWCF buildings (826,359 square feet of floor area), with a project goal of prolonging the buildings’ useful life for seven additional years. Assessments included architectural, structural, mechanical, plumbing, fire protection, and electrical criteria. TYLI’s deficiency/repair reports outlined recommendations for repairs and materials and/or system replacements for each building, with associated cost estimates.

AIRCRAFT MAINTENANCE FACILITIES REPAIR, BUILDINGS 532, 570 AND 700

For this comprehensive renovation, TYLI replaced and upgraded existing HVAC, fire protection, fire suppression, and fire alarm systems, including a new electrical design in support of the systems.

NEW RECIRCULATION SYSTEMS FOR BASE WATER TANKS

TYLI provided the design for a recirculation system for three elevated water storage tanks, which are needed to allow the continuous connection of base-wide external water supplies. The tanks ensure safe drinking water and support fire suppression systems.

MEZZANINE DESIGN, BUILDING 700

TYLI provided design and construction documents for a Simplified Acquisition of Base Engineer Requirements (SABER) contract for a 1,500-square-foot prefabricated, modular mezzanine office structure specifically designed around the infrastructure of an existing, 2-story hanger building. Design criteria included not interrupting day-to-day operation of an active aircraft maintenance hangar building and providing appropriate ingress and egress for personnel.

BASE WATER SYSTEM STUDY

Following an onsite inspection to determine the physical condition and adequacy of the base’s water distribution system, TYLI provided a report and model for the analysis of the potable water system using the EPANET program. The study determined existing potable water usage patterns for residential, administrative, and industrial users, as well as water requirements for fire protection, and specified system upgrades to meet future requirements.

BASE DRAINAGE STUDY

TYLI conducted a detailed survey and developed drawings and documents for a base storm water study involving an area of 3,015 acres, 789 of which are federally-protected wetlands. The project team assessed conditions of all drainage basins, major channels, ditches, and culverts to identify key drainage problems and then developed recommendations to resolve them.
