The project involves the repair and upgrade of the car wash area, including the installation of fabric tension shade structures over the auto detailing area, existing vending machines, pay stations at both entrances to the car wash, and the water reclamation and oil-water separator systems. The surrounding area around building B75065H will be repaved, with careful attention given to a historic train track located on the site. The repaving will be carried out without obstructing the track, ensuring it remains exposed and at its original elevation. The work will also feature striping, directional arrows, STOP markings, and one-way asphalt painting to enhance traffic flow and safety throughout the area.
ONLY DESIGN WILL BE AWARDED UNTIL ENVIRONMENTAL APPROVALS ARE RECIEVED.
DESIGN:
Shading Structure:
a. The design will include three options focused on optimizing traffic flow around the carwash to prevent congestion and enhance accessibility. Additionally, the steel framework and fabric cover will be engineered to meet Hawaii’s storm and wind load requirements, including design wind speeds up to 145 mph and compliance with impact resistance standards for windborne debris. Safety factors for structural stability, drainage, and flood resistance will also be incorporated. Final ratings and requirements will be confirmed during the design phase in coordination with local authorities and engineers to ensure compliance and durability.
b. A custom design of the steel framework and fabric cover shall be developed to ensure durability, aesthetic appeal, while also providing the storm rating of the product. The structural design shall be engineered to accommodate the required load, as well as to withstand wind and weather conditions, ensuring long-term performance and stability.
c. The contractor shall provide a warranty for the structure and tension fabric, ensuring protection against defects such as corrosion or structural failure. The entire structure, including the fabric membrane, shall be warranted for a minimum service life of 10 years.
Covering issues like UV degradation or tearing. The tensioning system, including cables and fittings, shall be covered for 10 years against failure. Regular maintenance, including cleaning and inspections, shall be required to maintain the warranty, and exclusions shall apply for damage caused by extreme weather, misuse, or neglect.
Paving & Traffic markings and Signage:
a. The Offeror shall provide all design and construction services necessary to mill down three inches of the existing pavement and repave approximately 52,000 sq ft around the car wash building B75065H (J-3 (P0-1)). It is important to note that no digging permit will be issued for this project, so all work must be limited to milling and repaving without any subsurface excavation.
b. The Contractor shall ensure the finished service drive allows for positive drainage away from the structures on site.
c. The Contractor shall coordinate with the POC and the Local Fire Department for all flame producing / burning activities required by this SOW and shall pay for and procure all required permits prior to construction.
d. The Contractor shall provide a warranty on all material and labor for a period of one year (longer if standard for materials/equipment) from the date of acceptance by the POC. The contractor will utilize industry-standard paving equipment, including cold planers for milling, asphalt pavers for laying new pavement, and rollers for compaction, ensuring all
equipment meets manufacturer specifications to support the quality and durability of the work under warranty.
e. The contractor shall include in the design all necessary drawings that reflect lane striping, directional arrows, STOP markings, and one-way asphalt painting details. This includes clearly marking traffic lanes with the appropriate solid and dashed lines and placing arrows to indicate the correct direction of traffic flow.
CONSTRUCTION:
Shading Structure:
a. The shading structure needs to be installed in the following areas (Attached RFP Section J-3 shading and paving Reference Map)
b. Cover the oil-water separator tank. The size of the shading structure is approximately 35x25 ft. Please follow the designated placement as shown in J-3 (S1-Pic 1).
c. The vending machine cover area is approximately 10x15 ft. Please refer to picture J-3 (S2-Pic 2) for reference.
d. Cover the detailing area, approximately 100ft x 50ft, above the vacuum machines, with a 10ft distance from the main street as the starting reference. J-3 (S3-Pic 3).
e. Cover the two pay stations in front of the two entrances to the car wash. The shading structure should be a standalone unit, approximately 12ft x 9ft. Please refer to the reference map J-3 (S4-Pic 4).
f. Fabric Overlay and Tensioning: Installing the fabric over the steel frame and securing it. Heavy-duty fabric material (PTFE or PVC-coated polyester) designed for outdoor exposure, UV resistance.
The contractor shall ensure that the structure is firmly anchored to a foundation,
utilizing materials as required by the site conditions, selecting the appropriate foundation
material based on the specific requirements of the project site.
2. Paving:
a. The contractor shall mill the existing pavement to a depth of 3 inches below the finished grade to accommodate the installation of a new 3-inch-thick bituminous concrete surface (Hot-Mix Asphalt Surface Course) over the full extent of the service drive. The new
surface shall be feathered or smoothly abutted to the existing road.
b. The train track is historic. It is imperative that the paving work performed under this contract shall not cover or obstruct the train track. The Contractor shall grind the existing asphalt below the level of the track, ensuring the track is not covered by the paving, thereby maintaining its historical integrity in accordance with applicable preservation standards.
c. The Contractor shall ensure all debris from any required pavement milling and/or scarification, be disposed of off-site at an approved facility.
3. Traffic markings and signage:
a. The contractor shall include any necessary signage, such as striping, arrows, STOP markings, and one-way asphalt painting details.
b. The Contractor shall install liquid thermoplastic paint permanent pavement markings, matching the original configuration and colors for Hickam car Wash, including but not limited to, fire lane delineations and car lanes.
