Site supplies for major infrastructure projects: why your supplier needs to understand the job

Buying PPE, dust control or calibration for a house extension is one thing. Buying it for a nuclear power station, a high-speed railway or a large solar farm is another. The products may look the same, but the rules around them don't. Major projects come with tighter site rules, booked delivery slots, longer paper trails and a supply chain that has to work with very little slack.

This guide covers what UK major projects typically expect from the businesses that supply them, and why a supplier who understands those demands saves project teams time and risk.

What makes major-project supply different

Big infrastructure schemes aren't just bigger sites. They run on a scale that changes how buying works.

  • Hinkley Point C in Somerset is the first new nuclear power station to be built in Britain for over 30 years. EDF says the project has worked with over 4,000 companies from across Britain, and that 64% of the project's value is going to British businesses (EDF).
  • Sizewell C in Suffolk describes itself as "a near replica of Hinkley Point C", drawing on the expertise and supply chain already established there. It publishes opportunities for suppliers through the Jaggaer platform (Sizewell C).
  • HS2 publishes direct and indirect contract opportunities, supply chain guidance and business support for suppliers (HS2 Ltd).
  • Large solar farms can be big enough to need a development consent order under the Planning Act 2008, as with the One Earth Solar Farm decision in Nottinghamshire and Lincolnshire (GOV.UK). Nationally significant schemes like these go through the Planning Inspectorate's consenting process.

On projects like these, much of the day-to-day kit is ordered by contractors and subcontractors rather than the client. Those buyers have to meet the main contractor's rules on safety, logistics and paperwork every time they place an order. A supplier who doesn't understand those rules creates more work for them.

Safety first: CDM 2015, site rules and the right kit

Every UK construction project falls under the Construction (Design and Management) Regulations 2015. On projects with more than one contractor, the principal contractor plans, manages, monitors and coordinates the construction phase. HSE's guidance for principal contractors says they must prepare a written construction phase plan before work starts, keep it under review, and ensure all workers get site-specific inductions and any further information and training they need.

In practice, site rules on a major project often go further than the legal minimum, and they shape what you can bring through the gate. HSE's page on site rules and induction explains how these rules are set and communicated. For buyers this usually means:

  • Specified PPE and RPE. Respiratory protection has to suit the hazard and the wearer, and tight-fitting masks need face fit testing. Getting the wrong model means a return, a delay or someone stood down. For spraying and similar tasks where the risk assessment calls for supplied air, an air-fed kit such as the Honeywell Airvisor 2 air-fed half mask kit, certified to EN 14594, is one option.
  • Dust and silica controls built into the method. On-tool extraction, M or H-class vacuums and air cleaners are often part of the approved method statement, not optional extras. In enclosed areas, a HEPA H13 air cleaner such as the DC Aircube 500 can run alongside on-tool extraction to reduce fine dust in the air. With its optional exhaust hose it can also create negative pressure in a sealed room.
  • Visible equipment status. Tags showing inspection status or HAV data, such as our HAV Tag Daily Use, let supervisors check kit at a glance.
  • Calibrated tools and instruments. Torque wrenches, gauges and electrical testers used on critical work need to be in date, with certificates to prove it.

A supplier who knows these expectations will ask the right questions before quoting: which standard, which size range, which certificate.

Getting the specification right first time

On a large project, "a mask" or "a dust extractor" is rarely enough of a spec. Send your supplier the method statement extract, the client's or principal contractor's requirement, and the quantity by trade or work area. It's the quickest way to avoid substitutions that won't pass the gate.

Logistics: booked deliveries, logistics plans and direct dispatch

Major sites can't take deliveries whenever a van turns up. Many projects run their deliveries under a Construction Logistics Plan and a delivery booking system, following approaches such as the CLOCS Standard. The Standard asks those involved to develop, implement and monitor a Construction Logistics Plan and keep it live throughout the project. It also covers delivery management systems for booking and controlling vehicle movements.

What that means for a supplier:

  • Delivery details matter. Site address, gate, booking reference, contact name and any vehicle restrictions need to be on the order and passed to the carrier.
  • Fewer, better-planned drops. Consolidating orders where possible cuts down booking slots and gate time.
  • Clear expectations on split deliveries. Where items come from different makers, buyers need to know up front that they may arrive separately.

GO2 orders are dispatched directly by the manufacturer or supplier, which keeps handling to a minimum. Multi-supplier orders may arrive separately.

Crossings on new and upgraded access roads

Where a project builds or upgrades public access roads, zebra crossings are marked with Belisha beacons. The Solar Powered Belisha Beacon Complete Kit (BelEco) is aimed at off-grid installations and sites with cable-routing limitations. The Mains Powered Belisha Beacon Complete Kit (BelMax) suits locations with a mains supply. For existing lighting columns with a cut-out, the Solar Powered Belisha Beacon Head Kit converts a beacon to solar, with the battery pack mounted inside the column. A pedestrian crossing sign mounts to a 76 mm post and comes with a fixing kit. See the full Belisha beacons range.

Paperwork and traceability: certificates, calibration and prequalification

Major projects run on records. Expect to be asked for product data sheets, conformity information and, for measuring equipment, calibration certificates that are traceable to national standards.

Calibration

Calibration is often where a project's audit trail is tested. GO2's calibration service covers torque and force, pressure, electrical and test, dimensional and inspection, and mass and temperature equipment. UKAS-accredited calibration is available, delivered through our accredited calibration partners, with traceable calibration certificates for your records and audits. Calibration can be on-site or off-site, with nationwide coverage, specialist and overseas calibration arranged, and urgent turnarounds on request.

In the words of our calibration page: "We've supported the demanding compliance standards of major UK infrastructure, including Hinkley Point C. That same rigour goes into every calibration we manage, whatever the size of the job."

Prequalification

Many major clients and contractors ask suppliers to prequalify before they can trade. Common routes include:

  • The Build UK Common Assessment Standard, with desktop and site-based certification levels, audited once a year by a Recognised Assessment Body. Build UK's list of organisations using the Standard includes HS2.
  • Achilles UVDB, a supplier prequalification community used in the utilities sector.
  • Constructionline, a database buyers use to find and check construction suppliers.

Which scheme applies depends on the client, the contractor and the size and type of work. Check the tender documents, and ask your supplier early what documentation they can provide for the products you're buying.

Frequently asked questions

What do major construction projects expect from suppliers?

Typically: products that meet the specified standard, deliveries that fit the site's logistics plan and booking system, and paperwork such as data sheets and calibration certificates. Many clients also expect suppliers to prequalify through a recognised scheme.

What is a Construction Logistics Plan?

It's a plan for how construction vehicles and deliveries will be managed to reduce risk and disruption. The CLOCS Standard asks those involved to develop, implement and monitor one and keep it live throughout the project.

Who is responsible for site rules under CDM 2015?

On projects with more than one contractor, the principal contractor plans, manages and coordinates the construction phase, including site inductions. Site rules are set out as part of that.

Do I need UKAS-accredited calibration for a major project?

It depends on the client's and contractor's requirements, so check the contract and quality plan. GO2 can arrange UKAS-accredited calibration through our accredited calibration partners, with traceable certificates.

Has GO2 worked on Hinkley Point C?

Our calibration page states: "We've supported the demanding compliance standards of major UK infrastructure, including Hinkley Point C."
