This PIN is to give advance notice to the market of a requirement for the design, manufacture, construction, and commissioning of a glasshouse facility at Cranfield University and the refurbishment of an existing glasshouse.
Also, the design, manufacture, construction and commissioning of a flexible and adjustable sensor platform complete with gantry, to support a weather sealed housing running along a ridged framework. To be housed within the new glasshouse facility.
Both the proposed new glasshouse facility and the existing glasshouse are used for research into plant growth, and are subject to a series of environmental controls to maintain the integrity of the research being undertaken.
Glasshouse Design and Construction (New Facility).
The design will include the glasshouse, the installation of the glasshouse and associated civils, and all mechanical and electrical interfaces.
The glasshouse will be constructed of a steel frame, and will incorporate within its design and construction and aluminum glazing system with upvc capping, incorporating aluminum personnel doors.
The glasshouse steel frame design and construction will allow internal access to the glasshouse for fork lift vehicles and this access and ingress will be by means of a galvanized steel electrically operated roller shutter door.
The glazing of the glasshouse will be by means of 4 mm toughened glass or similar.
The estimated dimension of the glasshouse are 12 000 mm wide by 10 000 mm high by 20 000 mm long.
The glasshouse environmental controls will require the design and construction of the frame of the glasshouse to incorporate roofing ventilation, the design and construction will include aphid screening within that roofing ventilation system.
The internal glasshouse environment will be controlled by an environmental computer. The computerized system will manage air exchange, heating and temperature, and thermal screening.
Air exchange will be by means of fans and will deliver 40 air exchanges per hour. Heating will be by means of tubular heat emitters. The thermal screening and shading will be by means of horizontal screens.
Civil and Mechanical Electrical.
The associated civils works for the construction of the glasshouse will include the laying of a concrete floor, service ducting, strip foundations, drainage and irrigation, a perimeter wall, and the foundations for the framework of the sensor platform.
Installation of a full electrical system.
Refurbishment (Existing glasshouse).
The scope of the refurbishment will include the modification of the existing electrical installation, mechanical ventilation systems, and the installation of horizontal shade screening and insect screens.
The sensor platform will support a series of sensors and camera's within weather sealed housing. The platform will have a walk on gantry. The estimated weight of the housing will be 500 kg.
The estimated dimensions of the sensor platform 3 000 mm wide by 1 500 mm high by 1 500 mm deep.
The sensor platform will be motorized to adjust the height of the sensor housing, and move the platform along the length of the ridged framework supporting tracks.
