Y -- Replacement of Aerobics Floor

This is a 100% Small Business Set Aside.NAICS code: 238330, Size $11.5M Magnitude: Between $25,000.00 and $50,000.00 This requirement is for a Sprung floor replacement which requires knowledge in Sprung Flooring. Contact William L. Tomson, Contract Admin, 402-294-2248 for additional questions/ information. STATEMENT OF WORK FOR NEW AEROBIC FLOOR Job site: Offutt Field House, Bldg 321 Offutt AFB, NE 68113 Scope of work: Area aprox 53? 5? by 45? 10?. Install a 6-mil vapor barrier over the concrete slab. A layer of ?? CDX Plywood with thirty two ?? rubber pads will be laid loose over the floor. A second layer of ?? CDX Plywood will be nailed to the first layer. 25/32? x 2 ?? 2nd and better Northern Hard Maple will be nailed to the plywood. Each board factory finished with 5 coats of UV cured Lacquer. Vented rubber bases will be installed at the walls and angled aluminum floor plates will be installed at the 4 doors with a gradual slope. Contractor will ensure there is a smooth transition in and out of rooms to exiting hallway floors. Contractor will ensure area is clean and free of debris, dirt and materials upon completion of work. Any damage to the room or areas leading into this room caused by the contractor shall be repaired per the original finish. The floor must consist of a hardwood sprung floor which meets the criteria outlined below in DIN standards. Please note the reference made under protective function which is the requirement for aerobic floor systems. Floor must have a minimum of five (5) coats of pre-finish. Contractor will be responsible for replacement of cove base in the room as well. Contractor will furnish signage and cordon off the area by the door to prevent people access to the area during construction. Hours of work are between 0700 and 1700 Monday thru Friday. Contractor and workers will be required to apply for a contractors work badge. The floor should be covered with a sleeper system and a hardwood surface. Maple tongue and groove and pressure treated beech are the recommended requirements for aerobic court surface. Court must adhere and meet DIN standards (Deutsches Intitut fur Normung). These standards require that a floor meet six criteria: 1. Shock absorption-a floor?s ability to reduce the impact of contact with the floor surface. The greater the shock absorption, the more protective it is because it reduces impact forces. An aerobics floor, for example, would need more shock absorption than a basketball court. 2. Standard vertical deformation- the actual vertical deflection of the floor upon impact. The greater the deformation, the more the floor deflects downward. Floors with minimal deformation are not good at absorbing impact forces. 3. Deflective indention- the actual vertical deflection of the floor at a distance 50 cm from the point of impact. The greater the indentation, the more likely impact at one spot will cause deflection at a distant point. 4. Sliding characteristics- the surface friction of the finished floor. A floor with poor sliding characteristics would be inappropriate for aerobics or basketball. 5. Ball reflection- (game action response) the response of a ball dropped on the floor compared to a ball dropped on the concrete. 6. Rolling Load- a floor?s ability to withstand heavy weight without breaking or sustaining permanent damage. The DIN criteria are then used sto evaluate the effectiveness of a floor. A floor will have one of three functions: 1. Sports function- a floor that serves a sport function enhances athletic performance. Surface friction and ball reflection are important here. 2. Protective function- a floor that serves a protective function reduces the risk of injury (e.g. from a fall) during activity. Shock absorption is important here. 3. Material technical function ? a floor that serves a material ? technical function meets the sports and protective functions. In a health/fitness facility, the gymnasium and multipurpose floors are classified under sports function or material technical function. The aerobics floor is classified under the protective function, with some sports function characteristics. Contractor shall provide the following floor surface that has a material technical function for Aerobic workout to meet the following DIN criteria: Shock absorption 53% minimum Standard vertical deformation 2.3 mm minimum Deflective indentation 15% maximum Sliding characteristics 0.5 to 0.7 range Ball deflection 90% minimum Rolling load 337.6 lb Submittals Required Flooring Material Specifications and sample 3ea Ramp detail Drawing of installation 3ea Schedule Progress schedule 3ea Pre-manufactured materials and sprung floor systems will be evaluated by Civil Engineerting/User personnel for acceptability for use to meet the above requirements.
