Replace Chilled Water System

Libby — Tue, 14 Jul 2009 13:58:38 +0000

Cost: $45,000,000
The work includes installing new chilled water lines and services to existing buildings that presently are serviced by the system and some new facilities plus incidental related work. The chilled water distribution system consists of insulated piping placed in existing shallow concrete trenches and direct buried. The mechanical rooms of the buildings served by the distribution system will be upgraded as required to achieve proper operation and improve efficiency as well as dependability. Chilled water is distributed to the Fort Stewart campus using three separate chilled water loops supplied from Central Plant Building 1412. Zone 1 serves buildings in the 600, 700, and 800 blocks, plus Buildings 2115 and 2125. Zone 2 serves buildings in the 500 and 600 blocks, plus Building 440. Chilled water entering buildings from the distribution loop is pumped through the building with a tertiary pump. Chilled water coils are designed for a 12ºF chilled water delta T. Some buildings at Fort Stewart use two-pipe systems with a dual temperature water pump. In other words, the building is either using chilled water or heating water at a given time but not both. Transfer from heating mode to cooling mode is accomplished with seasonal changeover valves. Other buildings have four-pipe systems with a dedicated chilled water pump. Control valves at air handling unit cooling coils are a mix of two-way valves and three-way valves. All buildings have constant speed tertiary pumps. Some buildings with two-way valves use pressure relief valves to circulate chilled water around the pump to prevent damage to the pumps when all two-way valves are closed. Other buildings use a constant volume bypass at the end of the line.

We are up and running with BIM and are in a position to assist the Savannah District as a leader in this new wave of technology which is destined to be the standard operating procedure of the future. The Savannah District Bentley BIM Coordinator, Trey Atkins, is very familiar with HGBD’s leading edge knowledge of Bentley BIM. HGBD is thoroughly familiar with the typical RFP Attachment F requirements and how to implement these requirements into a project.

Barracks Dining Facility

Libby — Wed, 08 Jul 2009 14:45:54 +0000

The project consists of a 30,500 gross square foot functional dining facility. The facility is similar to a colleg or university cafeteria in general function and quality providing receiving, storage, preparation, serving, queuing, dining, dishwashing, and equipment needed for appropriate food service and eating activities. The project provides a 544-seat dining facility, feeds 1,300 trainee soldiers per meal within 90 minutes, serves as a gathering space for group activities, and accommodates 104 staff members (57 max./shift). The scale and proportion of the exterior design relate to similar Fort Benning structures and future facilities proposed for the Harmony Church area. The masonry lower levels and upper-level EIFS accents above, and a standing seam metal roofs, provide for an easily maintained exterior while projecting an image consistent with Fort Benning standards. This is a design/build project presently in the Phase II evaluation stage.

Downing Fishing Pier Restoration

Libby — Wed, 01 Apr 2009 14:20:16 +0000

HGBD provided engineering design, permit acquisition, and contract services for the restoration of the recreational fishing pier located immediately adjacent to the Moon River Bridge and parallel to Diamond Causeway (State Route 204 Spur). The original pier was constructed in the 1970’s and consisted of 8-foot wide prestressed concrete double T-beams set on concrete piles and caps on 40-foot centers. The original pier was approximately 1,160 feet long, with 480 feet on one side, and 680 feet on the opposite side of the Moon River, with a shipping channel between the sections. The pier had been partially demolished in 1993 due to deterioration of the decking. HGBD was retained to verify the structural integrity of the remaining concrete caps and piles, design and prepare construction plans and documents for the most cost-effective means of repairing the pier, design paving and access improvements for two (2) existing access and parking areas, acquire State and Federal permits, provide construction inspection, and assist Chatham County with contract administration.
