Client: Facilities Engineering & Acquisition Division (NAVFAC Southwest)
This project was performed for the Naval Facilities Engineering Command (NAVFAC) Southwest Division at Naval Air Station Lemoore, Calif. The project is performed to the same quality and safety standards as the US Army Corps of Engineers uses in its projects, such as following the EM 385-1-1 and project personnel being required to have successfully completed the Contractor Quality Management course. The project was completed in three phases described below.
Phase 1: Install a 5-ton bridge crane in hangar for helicopter rotor assembly removal. Install a 2-ton ceiling-mounted crane in hangar for helicopter rotor assembly removal. Install three new covered lockable storage areas. Provide airfield markings for four helicopters. Provide Foreign Object Debris protection along the length of taxiway, approximately 50 ft from edge of existing shoulders. FOD prevention includes soil stabilization, asphalt replacement, and protection of airfield lights and other airfield items. 107,000 sf of soil stabilization
Phase 1 required a massive coordination effort to move jets from one area of the airfield to another to allow for restriping and soil stabilization. This portion of the project had to be completed by the end of September and was completed nearly two weeks ahead of schedule on Sept. 17. Tony Hooper served as the superintendent and quality control manager on this project for T. Simons Co., Inc. He was responsible for the expert coordination of all resources to include our own labor forces, subcontractors and suppliers.
Working on and around an airfield has its own unique set of conditions that have to be met to be successful, such seemingly benign requirements such as controlling dust and debris at the construction site become critical to maintaining safety for the aircraft. Also, driving on an airfield is different than day-to-day driving and requires an orientation class and maintaining contact with the control tower to do. Because of this even performing simple everyday tasks become items that require extensive coordination to complete.
Phase 2: Construct a new 1000 sf addition to hangar to provide a Para Loft Space. Includes concrete slab, spread footings on engineered compacted fill material, structural concrete wall and steel frame with insulated metal siding, steel truss system supporting a membrane roof system supported on metal roof decking with rigid insulation. Independent HVAC systems tied into direct digital controls system, fire alarm/suppression system interfaced with existing mass communication system, energy efficient lighting, sealed concrete floors, telecommunications, connection to existing power, compressed air, and connections to wastewater collection system. New addition ground to existing hangar grounding system. Architecturally compatible with existing exterior and have controlled roof access. Para Loft addition must meet the Explosive Safety Construction Requirements for Para Loft in Hangars outlined in OPNAVINST 5530.13D.
Phase 2 included a SCIF/EKMS high security room which was designed to be the most secured area in the region. T. Simons built the room to the required exacting standards and the room met all requirements.
A huge set of metal stairs designed to go from the ground to the mezzanine was delivered by the manufacturer 6 inches too tall. Tony's quality control procedures caught the error and sent them back to the manufacturer to be re-manufactured to the correct dimensions. When they were redelivered, they were perfect and set in place without further issues or any necessary intervention by the government.
Phase 3: Renovation of a 6400 square foot area by removing and/or adding walls, doors and associated ceiling within the existing building. Also includes adding sinks, vents and drain lines, pass-through windows, countertops, demolition and installation of chain link fencing, drop down ceilings, HVAC, lighting, demolition of tile, concrete floor refinishing, drywall, stairways, removing access ladder and securing hatch, modifying fire suppression system to meet UFC 3-600-10N, lighting, fixtures and bulbs, reconfiguring lighting switches, Navy and Marine Corps Internet (NMCI) drops and testing, painting, carpet cleaning, tile floor stripping, waxing and buffing, ceiling tile replacement, repairing door hardware and closures. Asbestos and lead abatement was also included in the scope of work.
The new addition for the Para Loft had to be blast-proof on the inside while meeting antiterrorism act requirements on the outside. This required the design to be carefully coordinated to ensure that all the requirements for both were met in a timely fashion. Windows in the original design were deleted to meet the blast-proof requirements and fire lanes around the building had to be re-routed due to the new building addition.
Construction on the new addition began Jan. 3 and had to be completed by April 30 because the end users were returning from deployment at that time. The Para Loft facility was signed off as completed on April 22, a week ahead of schedule.
