Security for Construction Sites and Contractors

Seccuro helps principal contractors keep sites secure from enabling works to handover, combining guarded gates, out-of-hours patrols and off-grid CCTV so plant, materials and programme are protected.

In brief

Construction site security is the combination of people, physical controls and technology used to stop unauthorised access to a site, protect plant, materials and fit-out stock, and keep the public away from hazards. It typically includes gate control during working hours, out-of-hours guarding or patrols, and monitored temporary CCTV.

The detail

Open any topic for the full explanation.

Security that follows the build programme

A site’s risk profile changes as the job progresses. During enabling works the exposure is plant and fuel in an open compound. Once the frame is up, scaffold gives intruders a route to height. During fit-out, copper, cable, sanitaryware and white goods arrive on site and the value of what can be carried away rises sharply.

We plan cover around those phases rather than pricing a fixed number of officers for the whole contract. A typical approach is a gate officer during working hours, with CCTV towers and mobile patrols out of hours, stepping up to static night guarding during fit-out or after an incident.

What officers do on a live site

On a staffed gate, officers check workers against the induction register, sign visitors and deliveries in and out, enforce PPE and site rules at the point of entry, and keep the gate closed between movements. Out of hours they lock down the site, carry out hoarding and perimeter checks, check cabins, stores and plant, and record findings on each visit.

Our officers support your site management team. They do not replace your induction process, permit-to-work system or traffic management plan, and they follow the assignment instructions agreed with your site manager.

Off-grid technology for sites without power

Many sites have no mains supply at the start. Seccuro provides Go Solar 365 AI CCTV Towers, Go Solar Lighting Towers that run from dusk to dawn on solar and battery power with no fuel, and Go ScaffSecure wireless scaffold alarms with twin PIR sensors and an infrared camera that captures each alert.

What we need to know to scope the site

To scope a construction site accurately we usually ask for:

  • The site plan, access points and hoarding line, and the phase of works.
  • Working hours and any planned weekend or night working.
  • Plant and high-value material held on site, and where it is stored.
  • Whether mains power and welfare facilities are available for officers.
  • Your induction and visitor procedures, and the site manager’s escalation contacts.
Deployment options
  • Working-hours gate control: One or more officers on the main gate managing people, deliveries and visitors.
  • Out-of-hours technology and patrols: Monitored towers or scaffold alarms with scheduled patrols and alarm response.
  • Static night and weekend guarding: Officers stationed on site overnight and at weekends.
Compliance considerations

Under the Construction (Design and Management) Regulations 2015, regulation 13(4)(b) requires the principal contractor to ensure “the necessary steps are taken to prevent access by unauthorised persons to the construction site”. HSE guidance HSG151, Protecting the public: your next move, explains how. Officers carrying out guarding hold an SIA Security Guarding licence. Where cameras overlook public areas or neighbouring property, UK GDPR and the ICO’s video surveillance guidance apply.

Security technology

Mobile patrols use high-visibility marked vehicles with satellite tracking and wearable digital patrol recording, and every visit generates a digital report. Towers, scaffold alarms and security pods connect to remote CCTV monitoring with 24-hour control room support.

Reporting

Each patrol visit produces a digital report of checks and findings, and every alarm activation is followed by an incident report setting out what was found and the action taken. Reports go to the site manager and project lead.

Who is responsible for security on a construction site?

The principal contractor, under the CDM duty set out above. The client should provide information about boundaries and access. A security provider supports those duties through gate control, patrols and monitoring, but the legal duty stays with the principal contractor.

Do we need a guard on site overnight?

Not always. Static night guarding becomes more cost-effective when high-value fit-out stock is on site, when the site has suffered repeated incidents, or when the perimeter cannot be secured physically. At other times the out-of-hours technology and patrols described above are usually enough.

Can you provide CCTV where there is no power?

Yes. The towers described above need no mains supply, and Go ScaffSecure scaffold alarms run on a lithium battery lasting 3 years or more, so they suit sites before mains power is connected.

How is construction security priced?

Price depends on the number of officer hours, whether cover is static or patrol-based, the amount of technology deployed, monitoring hours and the length of the hire. We price around your programme, so cover can be stepped up or down as risk changes. Case studies are available on request.
