Writing a Parking Barrier Technical Specification for Tenders

Define the Scope and Site Conditions

Start by stating exactly what is being supplied: the number of barrier units, their location in the car park, and whether installation, commissioning and training are included. Describe the site clearly, including the lane width, the expected traffic volume, the entry and exit configuration, and any space constraints for the boom arm.

• Number and type of lanes (entry, exit, or both)
• Expected daily cycles and peak usage
• Power supply and cabling provided by others
• Exposure to weather, wind and coastal conditions

Set Performance and Operating Requirements

Specify how the barrier must behave in operation. Define the required opening and closing time, the duty cycle the motor must sustain, and the expected service life of moving parts. State the acceptable noise level and whether the unit must operate during power interruptions through a battery or manual release.

Ask bidders to state their stated values in their offers so that products can be compared on the same basis.

Specify Safety Features and Standards

Safety requirements should be explicit. Require obstacle detection that stops or reverses the boom if a vehicle or person is under it, and specify the type of detection (loop, photocell or radar). Require compliance with the relevant Israeli and international electrical and machinery safety requirements and ask for documentation proving that compliance.

Where barriers sit beside pedestrian routes, require the safety arrangement to be stated in the offer. Exact technical values should be confirmed with the project engineer before publication.

Describe Materials, Finish and Durability

Define the materials for the housing, boom arm and fixings, since these determine corrosion resistance and lifespan. For exposed outdoor installations, require hot-dip galvanizing for steel parts and an appropriate powder-coat finish, and ask bidders to describe the finishing process they will use.

• Housing and boom material and thickness
• Corrosion protection method and colour
• Ingress protection rating for the control box
• Fixings and anchor specification

Define Installation, Testing and Commissioning

State who is responsible for foundations, anchoring, wiring and levelling, and what the contractor must provide before handover. Require a documented commissioning procedure that tests every safety function and the operating cycle under real conditions. Ask for test records to be delivered as part of the handover file.

Set Clear Acceptance Criteria and Documentation

Describe how the delivered barriers will be accepted. List the tests that must pass, the drawings and operating manuals required, and the spare parts list the supplier must provide. Requiring a written description of the warranty conditions and the service response process helps the client compare bids fairly, without relying on informal promises.

Frequently asked questions

Should a parking barrier tender include the expected number of cycles per day?

Yes. Stating the expected daily cycles and peak usage lets bidders select a motor and control system rated for the real duty, which avoids premature failure.

Why is obstacle detection important in the specification?

Obstacle detection protects vehicles and people from the moving boom. Requiring a specific detection type and a documented stop or reverse function makes safety verifiable during acceptance testing.

Do I need to name a specific brand in the specification?

Brand naming can restrict competition. It is usually better to define performance, materials and standards, and allow bidders to propose equivalent solutions that meet them.

What should be included in the handover documents?

Include as-built drawings, operating and maintenance manuals, commissioning and test records, a spare parts list and the written warranty conditions.

Common mistakes to avoid

A common mistake is describing the barrier only by its brand or appearance, leaving performance and safety open to interpretation. Another is omitting site conditions, so bidders quote products that do not suit the actual traffic and weather.

Our recommendation

Write the specification so that every requirement can be checked during acceptance testing. If a line cannot be verified on site, rewrite it with a measurable criterion before issuing the tender.

Summary

A strong parking barrier technical specification defines scope, site conditions, performance, safety, materials, testing and acceptance criteria in verifiable terms. This allows fair comparison of offers and a smoother handover.
