Construction traffic management and site access control
Discover the trusted solutions and expert services crafted to protect and support your unique needs.
We provide professional construction traffic management services to keep your site safe, compliant, and running efficiently.
From qualified traffic marshals controlling vehicle movements to experienced gatemen managing site access, our team is trained to handle the demands of busy construction environments. We operate nationwide with a particular focus on South England and the Midlands.
Traffic Marshal Hire for Construction Sites
Our traffic marshals are fully trained and experienced in managing vehicle and pedestrian movements on and around active construction sites. Working to your site-specific traffic management plan, they provide a visible, proactive presence that reduces the risk of accidents, keeps deliveries flowing, and ensures your site remains compliant with health and safety legislation. All marshals hold relevant training certifications and are deployed through our HitDesk workforce management platform for full transparency and accountability.
Site Gatemen & Access Control for Construction
Controlling who enters and exits your site is fundamental to both security and compliance. Our site gatemen manage access points professionally, checking credentials, logging visitors, and ensuring only authorised personnel and vehicles gain entry. Working closely with your site management team, they help maintain an accurate site register at all times — essential for emergency evacuations and regulatory compliance.
Construction Delivery Management System (DMS)
Unmanaged deliveries are one of the biggest causes of congestion, delay, and safety incidents on construction sites. Our Delivery Management System provides a structured, technology-driven approach to scheduling and coordinating site deliveries, reducing conflicts between vehicles and trades, minimising road impact, and keeping your programme on track. Ask our team about how DMS can be integrated into your existing site operations.
Construction Traffic Management — Nationwide Coverage
All Andor Group traffic management personnel are vetted, trained, and managed through our dedicated operations team. We work directly with principal contractors, site managers, and logistics coordinators to ensure our staff integrate seamlessly into your site team. With flexible deployment options and nationwide reach, we're ready to mobilise quickly wherever your project is based.
Construction site access control
Access control is where traffic management and site security meet, and on most sites it is the weakest point of both. The gate is open for most of the working day, it is the one place every person and every vehicle passes through, and it is usually staffed by whoever happens to be nearest when a lorry arrives.
Done properly it answers four questions continuously: who is on site, whether they are inducted, what has been delivered, and what has left. Those are not security questions alone — the first is a fire roll call, the second is a CDM obligation, and the last two are how you find out that material is going missing before the shortfall appears at first fix.
In practice access control means a controlled entry point with someone accountable for it, induction checked before anyone gets past rather than afterwards, visitors and subcontractors signed in and out, deliveries booked against the programme, and a live record rather than a book that gets written up later. On sites where parking is constrained it also means controlling who brings a vehicle on at all, which is frequently the difference between a workable compound and a blocked haul route.
Our construction site access guide works through how to set this up from scratch. Temporary sites and early phases are the hardest, because the permanent arrangements do not exist yet. That is precisely when an unstaffed gate does the most damage, and it is usually the phase where cover is left until later.
What a traffic marshal is responsible for
A traffic marshal is responsible for every movement of every vehicle on site, and for keeping those movements away from people. Specifically: directing vehicles in, positioning them for offloading and directing them out; controlling reversing manoeuvres from a position within the driver’s sight using agreed signals, with the area behind the vehicle physically checked first; holding pedestrians while a vehicle crosses and holding the vehicle while people pass; keeping vehicles on designated routes; and stopping a movement rather than improvising when something changes.
They are also responsible for reporting what is not working — a route blocked, a delivery arriving where it should not, a near miss at the gate. A pattern of near misses at one location is the warning that arrives before an injury, and it only exists if someone records it.
Whether marshals are a legal requirement is a question we get constantly, and we answer it properly in are traffic marshals legally required? The terms marshal and banksman overlap in everyday site use. Banksman usually refers specifically to controlling a reversing or manoeuvring vehicle; traffic marshal covers the broader role. Our people are trained for both. Full detail on the traffic marshals page.
What a gateman does
A gateman controls the access point itself rather than the vehicle movements around it. They check inductions before anyone gets on site, sign subcontractors and visitors in and out, book deliveries in against the programme and sign material in on arrival, and maintain the live site register that an evacuation depends on.
It is the least glamorous role on a construction site and frequently the one that pays for itself fastest, because it removes the cause of most access problems rather than recording the consequence. If you are weighing the role up, what does a gateman do on site? covers a typical day in detail. On quieter sites one person can reasonably cover both marshalling and the gate; where deliveries are frequent the two conflict, because a marshal cannot leave a vehicle movement to check an induction record. More on the gatemen page.
Traffic management plans
A construction traffic management plan sets out how vehicles and pedestrians move on and around a site: entry and exit points, internal routes and turning areas, offloading and storage locations, pedestrian routes and crossing points, signage and barriers, delivery scheduling, and the interface with the public highway and footway.
The plan is the design. What determines whether it works is enforcement, because plans assume compliance and sites do not comply on their own. Routes get blocked, a delivery lands in the wrong place, and people take the short cut. We staff and implement the plan, supply the signage and barrier provision where required, and report where the plan has stopped matching the site so it can be revised rather than quietly abandoned.
Our traffic management plan guide sets out what a plan should contain. Where a plan does not yet exist, we will tell you what the site needs before quoting people to stand in it.
Deliveries
Most congestion and a good deal of loss traces back to uncontrolled deliveries: a vehicle arrives unbooked, the gate admits it because turning it away causes an argument, it blocks the route, and nothing is recorded about what came off it.
Our delivery management system is our own build, and its value is that the booking is enforced by the same people controlling the gate rather than living in an office nobody at the entrance can see. Vehicles are booked against the programme and the site’s actual capacity to receive them, arrivals are checked against the booking, and what enters and leaves is recorded at the point it happens.
Keeping vehicles and people apart
The most dangerous routine activity on a construction site is a vehicle reversing. It happens dozens of times a day, it is entirely normal, and it is where people are most often struck.
Segregation is a design problem first — separate routes, defined crossing points, barriers where the two must meet. But on a constrained urban site the gate often opens straight onto a public footway, and the people most at risk are not inducted, not wearing high-visibility clothing and not expecting a vehicle. That interface needs a person controlling it, not a sign.
Accreditation, and what it covers
Andor Group holds ISO 9001, ISO 14001 and ISO 45001. Worth being precise about those on this page: the certificates are scoped to security guarding services, so they cover the officers who staff your gate and not the traffic management arrangement itself. We state the scope rather than leave it implied, because it is printed on the certificate and a buyer who pulls it will see it.
Alongside those we hold SafeContractor accreditation and SSIP approval, and Constructionline Gold membership certified against the Common Assessment Standard. Certificate numbers, issuers, scopes and expiry dates are all on our accreditations page.
Where we work
We provide traffic management and site access services across Hampshire and the south of England, including Southampton, Portsmouth, Winchester, Basingstoke, Andover and Alton, along with London and the surrounding counties, and work nationally for clients running sites in several regions. Our head office is in Southampton.
Common questions
Do traffic marshals need an SIA licence?
Marshalling itself is not a licensable activity. Where the same person also performs security duties such as access control or guarding, an SIA licence is required for that element, and ours hold one.
How many marshals does a site need?
It depends on the number of access points, how frequent deliveries are, and whether the site meets a public footway. A single tight entrance with regular deliveries usually needs one; separate entry and exit, or an internal route crossing a pedestrian route, needs more.
Can one person cover the gate and marshalling?
On quieter sites, yes, and it is often the sensible arrangement. Where deliveries are frequent the roles conflict and you need both, because neither job can be left halfway through. We set the two side by side in traffic marshal vs gateman.
Can you cover a one-off operation?
Yes. Large pours, crane lifts and steel deliveries often need marshalling for a day or two rather than a standing arrangement, and we cover those.
Do you supply signage and barriers?
Marshals arrive equipped for the role with high-visibility PPE and signalling equipment. Site signage, barriers and physical provision are supplied as part of the traffic management arrangement and quoted separately.
What do you need from us to start?
The traffic management plan if one exists, the site layout showing access points and internal routes, the delivery schedule and booking arrangements, the hours of vehicle movement, where the site meets the highway or a footway, and any planning or local authority restrictions.
