Galliford Try wins £110m River Mease pipeline: what subcontractors should check before pricing

What happened

Galliford Try’s Environment business has been appointed by Severn Trent Water to deliver the £110m River Mease Improvement project. The scheme is driven by Water Industry National Environment Programme (WINEP) requirements and includes a 23km cross-country pipeline conveying flows from the Packington and Measham treatment works. Galliford Try’s announcement also identifies a section at the A42 crossing and an outfall into the River Tame.

The award sits alongside a wider relationship. In a May 2026 investor presentation, Galliford Try described its Severn Trent work as approximately £100m a year across infrastructure, non-infrastructure and MEICA framework positions, shown as running to 2028. That figure describes Galliford Try’s broader framework activity. It does not identify the value or timing of packages available to outside subcontractors on River Mease.

Does this affect you?

If your business can deliver pipeline civils, specialist crossings, treatment works interfaces or the support services needed on a long linear scheme, the award is a reason to establish whether Galliford Try is seeking supply-chain interest. The published announcement does not provide a package list, procurement timetable, route drawings or subcontract terms. Confirm the opportunity before allocating substantial estimating resources.

For commercial teams, the immediate question is not how to divide £110m into assumed packages. It is which scope will be tendered, when information will be issued, and what risks your price is expected to carry.

Subby Mate: if you are on the tools

The one thing: If you already work in water or linear civils and have a Galliford Try contact, ask whether supply-chain enquiries are open for River Mease, who is procuring your trade, and when packages are expected to go out. Give a short account of the relevant work and resources you can actually supply.

• A 23km route can involve moving crews and plant between work fronts. Before quoting, establish the proposed access points, working sequence, travel within the route, delivery locations and welfare arrangements. The distance alone does not tell you how many moves or how much waiting to allow.
• If you have experience with crossings, reinstatement or work around operating treatment assets, explain that experience specifically. The A42 crossing and works interfaces are identified in the announcement, but the exact subcontract packages and construction methods have not been published.
• Have current insurance and trade competency records ready. Ask what project-specific inductions, water hygiene, permits and task qualifications will be required; the answer will depend on the work you are asked to perform.

If you are a subcontractor QS

Build a pricing basis for each work front. Request the route and access information, ground and utility data, construction methodology, quantities, programme and reinstatement specification applicable to your package. State the assumed number and location of work fronts, crew moves, working hours, material delivery points and extent of your temporary works and welfare. Identify items that cannot yet be measured or priced reliably and propose how they will be valued when defined.

Allocate access and delay risk expressly. Establish who secures landowner permissions and when each working area will be released. Check the subcontract’s notice requirements and whether you can recover time and cost for delayed or fragmented access. If an agreed work front is unavailable, record the location, planned activity, affected resources and actual impact promptly, then issue any required notice within the contract period.

Keep this scheme’s rates tied to this scheme. Galliford Try’s framework position may create later opportunities, but the investor presentation does not say that River Mease subcontract rates will apply to future jobs. Give your quotation a clear validity period, define the quantities and assumptions behind unit rates, and require separate agreement before rates are used for a different location, programme or call-off.

Read the proposed order, not just the framework label. Ask which contracting entity will appoint you, what documents are incorporated, who carries design and testing obligations, and how applications, variations, retention and final account will be administered. Do not infer your subcontract terms solely from the infrastructure, non-infrastructure or MEICA headings in the investor presentation.

If you are a main contractor QS or commercial lead

Galliford Try reported an infrastructure order book of about £1.7bn at 31 December 2025, including £1,167m in its Environment business and £547m in Highways. Environment is therefore a substantial part of its secured work, although that number is not a River Mease package budget or a measure of water work alone.

If your own Midlands work needs the same specialist civils capacity, ask suppliers what crews, plant and supervision are already committed over your intended programme. Confirm availability and quotation validity for critical activities rather than assuming this one award has already absorbed the regional market.

For your own linear tenders, test whether access, ecology constraints, crossings, permits, commissioning interfaces and reinstatement are reflected in both your programme and subcontract scopes. A realistic risk register should identify the information outstanding, the party responsible and the date by which a pricing decision is needed.

Do this week

1. If you want to bid: ask Galliford Try whether your trade is being procured for River Mease, who the package buyer is, and when scope information will be available.
2. If you are preparing a price: create a one-page schedule of assumptions covering route access, work fronts, moves, welfare, deliveries, ground conditions and reinstatement. Adapt it to the actual tender information before submitting it.
3. If you depend on the same specialist trades: obtain written capacity and rate-validity indications for your own 2027 programme. Treat those responses as the basis of your forecast, rather than the size of another contractor’s award.
