What Information to Prepare Before Requesting a Quote for a Tensile Membrane Structure Carport

If you are a property owner, facility manager or procurement buyer planning a membrane canopy for vehicle parking, you do not need finished drawings before your first enquiry. However, preparing four categories of information in advance will make design coordination and quoting much faster: the intended use and parking object, site dimensions and surroundings, any special operational requirements, and the supply scope you expect the fabricator to cover.

1. State the intended use and parking object

Two projects may both be described as a carport, yet a residential canopy shading private cars differs considerably from a canopy covering charging stations with EV chargers. When submitting an RFQ (Request for Quotation), state the project type directly: residential community, business park, commercial plaza, charging station, school or factory site — and whether the canopy will cover cars, bicycles (bicycle shelter), or both. The intended use affects membrane material selection, canopy shape and drainage arrangements.

2. Prepare site dimensions and surrounding conditions

The length and width of the parking area, the maximum buildable height, and nearby obstructions such as walls, trees, buried services or existing structures all influence the span layout and foundation positions. If you already have dimensioned data or a simple site plan, include it. If not, a rough description of the area and its boundaries is enough to start.

Regarding site measurement: for smaller sites, dimensions can usually be confirmed through communication between both parties. For larger sites, and once confirmed through discussion, drone-based site surveying can be used to reduce manual measurement errors. Which method applies should be agreed in the course of coordination.

3. Special requirements of the operating scenario

Charging stations and factory sites often carry additional requirements that should be raised early. For example:

• Charging station canopies: charger positions and clear height under the canopy
• Factory carports: vehicle circulation routes and loading/unloading needs
• Schools: periods of use and supervision considerations

You do not need to cover everything at once, but anything that affects the design is best raised as early as possible.

4. Agree the supply scope after forming a requirements brief

Consolidate the points above into a short requirements brief, then move into scheme discussion. Qingsong Membrane Structures offers integrated design, fabrication, surface treatment and installation. Once the requirements brief is clear, arrangements for each stage can be confirmed item by item.

Please note that design responsibility, interfaces with your local project engineer, and the exact supply scope — scheme design only, or design plus custom fabrication and delivery — are matters to agree with the supplier and your engineer before contract. If handover to local installers is involved, packing lists and material documentation should be defined as part of that agreement.

Checklist: what to have ready before enquiring

• Project use, parking object and scenario type
• Site dimensions, boundaries and nearby obstructions
• Whether charging, fire-safety or other supporting conditions are already fixed
• The supply scope you wish to entrust: scheme design only, or design plus fabrication and installation
• Preferred site measurement method: manual measurement or drone surveying
• Target start date and on-site working conditions

To begin, share your project location, intended use, dimensions or available drawings, and the supply scope you need, so the design coordination and fabrication arrangements can be reviewed.
