Specifying Electric Gates in Construction Tender Documents

t283-29

A clear electric gate specification in a tender lists the gate type (sliding or swing), opening dimensions, drive and control requirements, safety devices, material and finish, and installation scope. Precise written requirements let every bidder price the same work and reduce variations during construction.

Why the gate specification matters in a tender

An electric gate is a small line item in a large project, but vague wording on it often leads to disputes later. When one bidder assumes a swing gate and another prices a sliding gate, the comparison becomes meaningless and the final cost changes after award.

A well-written specification protects the contractor and the developer alike. It defines exactly what is included, what is excluded, and which standards and finishes apply, so that every bid answers the same question.

Define the gate type and dimensions

Start by stating whether the gate is sliding or swing, and whether it is single or double leaf. Give the clear opening width and height, the leaf dimensions, and the side on which the opening is measured. Note any slope, pavement level or obstacles that affect the track or swing path.

Gate type and number of leaves
Clear opening width and height
Direction of opening and swing clearance
Ground conditions and track or pillar requirements

Specify the drive, controls and power

Describe the motor type and its intended duty cycle, given the expected traffic at the entrance. State the power supply, whether a backup battery is required for power cuts, and the control method, such as remote transmitters, keypad, intercom integration or access control.

Ask the bidder to confirm compatibility with the building's existing intercom or access system. Mentioning the required cable routes and the location of the control cabinet avoids surprises in the electrical scope.

Set the safety requirements

Safety devices should be explicitly listed. Typical requirements include photocells, safety edges on the leading edge, obstruction detection that reverses the gate, and emergency release for manual operation. Refer to the relevant Israeli standards that apply to automated gates and confirm the required devices with your engineer, as exact values depend on the project.

Also specify the signage and the warning light or audible alarm that operate during movement.

Material, finish and corrosion protection

Define the structural material, such as steel or aluminum, and the wall thickness or profile where relevant. For steel gates, state the corrosion protection method, for example hot-dip galvanizing followed by powder coating, and the colour reference. Clear finish requirements prevent a cheaper unprotected finish from being substituted at the bid stage.

Include requirements for infill, such as solid panels, perforated sheet or bars, since these affect wind load and appearance.

Installation scope, testing and handover

The specification should state who performs the civil work, such as foundations, pillars and cable ducts, and who performs the electrical connection. Include the testing required before handover, such as safety device checks, force measurement and a functional run with the client present.

Request documentation at handover, including operating instructions, a maintenance schedule and the warranty period as agreed in the contract, so that the building manager has everything needed after completion.

Frequently asked questions

Should a tender specify sliding or swing gates?

Yes, if the design requires a particular type, the tender should state it clearly. If you accept either option, say so and ask bidders to price both separately so the comparison remains fair.

Do I need to include safety devices in the specification?

Yes. Listing photocells, safety edges and obstruction detection in the tender ensures each bidder includes them. Confirm the specific requirements with your engineer and the applicable standards.

What finish should I write into the tender for a steel gate?

State the corrosion protection method and the final coating, such as hot-dip galvanizing followed by powder coating, along with the colour reference. This prevents substitution of a lower-grade finish.

Who is responsible for the electrical connection?

The tender should say explicitly whether the gate supplier, the electrical contractor or the main contractor provides the power supply and cabling. Unclear responsibility is a common source of extra costs.

Common mistakes to avoid

Leaving the gate type, safety devices or finish undefined in the tender invites incomparable bids and later variation claims. Forgetting to assign responsibility for the electrical and civil work is equally costly.

Our recommendation

Attach a simple drawing with dimensions and a one-page checklist of required devices and finishes to the tender. Ask bidders to confirm each item in their offer so you can compare them line by line.

Summary

A precise electric gate specification covers type, dimensions, drive, safety, finish and installation scope, giving every bidder the same basis for a fair comparison.
