The Citrus Research Board (CRB) is seeking quotes from greenhouse construction vendors to build a 24’ x 30’ greenhouse to grow high-quality citrus plants free of pests to support research on citrus pests and disease in an adjacent containment laboratory in Riverside, California. The project will require quotes for a complete package to design and build the greenhouse (including seeking permits) on an existing concrete slab outside of the containment laboratory. Electric, water, and sewer are available nearby. While we desire the capacity to grow citrus pest-free at a very high level of assurance, using a positive pressure HVAC system and an entry vestibule/passageway, there will not be a direct connection between the greenhouse and the permitted containment laboratory nor will it need to meet the standards to be permitted as such.
A brief description of the project is below. A full package of information with a PDF schematic drawing, layout of plumbing and concrete (slab and grade), site photos with a Statement of Work showing all the requirements for the RFQ is available to vendors interested to bid.
Project Description: The Structural Package will include the greenhouse structure, positive pressure evaporative cooling system with automatic shutters, heating system including circulating fans, air moving exhaust system, overhead room lighting, and automated environmental control system. The design and construction of the greenhouse need to take into consideration the environmental conditions in the Riverside, California area. Required operating temperature should allow reasonable ecological control to maintain between 65 F and 90 F. The Structural Package should be delivered to the location and installed as a turn-key greenhouse which includes all electrical and plumbing. All building permits required for construction should be a part of the bid submittal. Please provide an itemized listing of costs for the Structural Package. A complete set of drawings and specifications will need to be reviewed and approved before acceptance of a bid.
Insect control also needs to be addressed in the bid submittal as part of the turn-key package.
A greenhouse entry enclosure needs to be designed and included in the bid submittal as part of the turn-key package.
