This 9,000 sq. ft. multiple purpose storage and office building was completed on schedule. Several on cost design modifications were implemented to further meet the operational requirements of the project including changing the fire protection system to a dry pipe system, lighting improvements and modifications to the high voltage electrical system that supported the building.
This project required an older facility to be reconditioned to accept the Emergency Operations Center to be moved into this space. In addition to architectural work changes to the data, communication, audio visual systems were extensive. Also, a complete custom office furnishing package was installed.
Features of this project included a new metal building, large metal canopy at existing warehouse, heavy reinforced concrete slab and footings and electrical system, temperature and humidity control, and fast acting roll up doors.
This fast track contract was a security “safe room” conversion of an existing building. This contract was scheduled for an eight week completion and CWF finished the project in six weeks and received a Letter of Appreciation and service medal from Navel Security for an outstanding job.
This project required the design and installation of a new water cooling system including a large cooling tower, vented storage tank, piping, control’s and supporting electrical components to replace the water cooling system that was in use. Most of the mechanical components and piping were required to be made of stainless steel. Three Autoclaves were supported by this cooling system. Each Autoclave was switched to the new cooling water, commissioned and certified individually to minimize the impact to the operation of the Composite Shop.
This design-build project is in the final stage of design. The blast booth is large, about 3000 cubic feet and will be constructed so personnel inside the booth may clean flight hardware by spraying abrasive material on components as part of an operational process. The abrasive material inside the booth will be captured and the air used in the booth will be filtered through a bank of hepa filters and released. New concrete foundation will support the blast booth and structural steel assembly will support the filter bank, cyclone separator and exhaust stack. Additionally, large shop equipment will be relocated and new make-up air unit installed on the shop roof. This project required application to the Florida Department of Environmental Protection to issue an Air Construction Permit and Title V Air Operation Permit. These permits are necessary for any facility that will release emissions into the atmosphere.
This project required the installation of ultra violet (UV) light fixtures inside all of the 614 air handlers at Mayport Naval Station. The purpose of the light fixtures was to kill bacteria and mold spores in the air system which reduces organic deposits on the HVAC coils thereby increasing efficiency of the HVAC system. Also, there are health benefits to cleaner air in the buildings. However, UV lighting is harmful to the eyesight of anyone that looks directly into the light. Shielding and a safety interlock that shut off the light if the air handler was opened was planned to protect personnel’s eyes. The C.W. Ferrell Construction value engineered the scope of work to install an alternative to the ultra violet lights. A technology called “Photohydroionization” or PHI which does not have the eyesight hazard of UV lighting. The PHI system was accepted and installed. This eliminated the need for shielding and safety interlocks on the air handler access doors and reduced the cost and duration of the project.
This design-build project was two different scopes of work under one contract. First, Hangar 124 required the removal and replacement of existing light fixtures and circuits in a large aircraft hangar while the Hangar remained occupied and operational. The illuminated area of the Hangar was over 60,000 square feet and required 172 light fixtures. An induction lighting system was selected as the most energy efficient system that would deliver adequate light for the needs of the facility. Light levels in the Hanger were more than doubled while energy consumption was reduced by more than 10%. During the installation of the fixtures emergency lighting and a daylight harvesting system were added to the scope of work.
The second scope of work was to remove the existing 400 Hz Electrical Converter Units and replace them with two new 45KVA 400 Hz Converters. New circuits, panels, breakers and disconnects were also installed.
This project required the installation of nine (9) electrical switches that are mounted at the top of electrical poles at various locations around NAS Jacksonville. The switches are used to manipulate the way electrical energy is routed around the large electrical grids at the base. One of the challenges of this project was to coordinate when to electrical power could be shut down to enable work to be performed as each electrical grid supports a multitude of buildings. It was determined the best time to replace the switches was overnight using an abundance of equipment and manpower. The work was successfully performed over several nights with minimal impact to base operations.
This is a design-build project at a remote airfield that is scheduled for renovations over the next several years. The primary work includes several miles of underground electrical circuits, new electrical vaults, switchgear, sitework and concrete slabs to support the forthcoming electrical infrastructure. Additionally, a 60 foot light tower will be removed and new light installed on the existing airport tower.
This electrical project is being performed at a secret rated facility and requires a contractor with a confidential clearance to obtain the contract. Terms of our security agreement and contract do not allow public discussion of the contract. Information can be provided by the Contracting Officer at Kings Bay Nuclear Submarine Base Georgia. His information is included in our reference section.
This marine project consists of installation of three mooring dolphins constructed with 90 ft., 18” concrete piles driven on a 45 degree angle, deck spall repairs, rip-rap stabilization, bollards, cleats, structural pile jackets and security fence.
This consists of rehabilitation of three large berthing wharfs. Major aspects of the project consist of; fender repairs above and below deck spall repairs, installation of quay wall and test anodes, structural and non-structural pile jackets and concrete pile caps.
This was an emergency fast track diver assisted air lift dredge project. This underwater project was slated for 50 days. The work was performed at the caissons of the largest dry-dock in North America and was completed in 18 days.
