What's changing in UK civil engineering

Every year, the construction press runs the same set of articles about the “future of civil engineering.” Robots laying bricks. 3D-printed houses. AI replacing project managers. It’s been the future for about a decade now, and none of it has landed on a typical UK civils site in any meaningful way.

What is changing, right now, in ways that directly affect groundworks and civil engineering subcontractors, is less glamorous and far more important. The work pipeline is shifting towards renewable energy and industrial logistics. Procurement platforms are replacing the old phone-call-and-a-handshake route to finding work. BIM is creeping down the supply chain. And the people who know how to run an excavator or set out drainage to the right falls are retiring faster than they’re being replaced.

Here’s what’s actually happening and what it means if you run a civils firm.

The renewable energy pipeline is enormous

The numbers are hard to overstate. The UK government’s target of decarbonising the electricity grid by 2030 requires roughly 50GW of new solar capacity and 55GW of offshore wind (with onshore substations and grid connections on land). Add battery storage, grid reinforcement, EV charging hubs, and hydrogen infrastructure, and you have the largest single source of new civil engineering work in the UK for the next decade.

What this means for groundworks contractors

Solar farms need access roads, cable trenching, inverter pad foundations, substation bases, perimeter fencing, and surface water drainage. A 50MW solar farm can require 10-15km of cable trench, 200+ concrete pads, and a full access road build. These are straightforward civils packages, well within the capability of any competent groundworks firm, but the procurement routes are different from traditional construction.

Battery Energy Storage Systems (BESS) require reinforced concrete foundations for containerised battery units, transformer pads, control building bases, security fencing, and fire suppression infrastructure. Sites are typically 1-5 acres. The groundworks package on a 100MW BESS site can run to seven figures.

Substation and grid connection works involve heavy concrete foundations, deep cable ducting, and earthing systems. These are specialist packages but increasingly being procured from civils contractors rather than utility companies’ in-house teams, particularly for Independent Distribution Network Operators (IDNOs).

EV charging infrastructure at motorway service stations, fleet depots, and public car parks needs HV cable installation, transformer foundations, and surface reinstatement. National Highways and local authorities are procuring this work through frameworks that are open to NERS-accredited civils contractors.

How to position your firm

If you’re not already pricing renewable energy work, start now. The main contractors in this space (companies like Wates, Robertson, Galliford Try, and specialist EPC contractors) are looking for groundworks subcontractors who understand cable trenching, duct installation, and foundation construction. NERS accreditation is increasingly a prerequisite for utility connection work on these sites.

Industrial and logistics: still building

Despite economic uncertainty, the warehouse and logistics sector continues to build. The shift to online retail, the reshoring of supply chains post-Brexit, and the growth of cold storage and food distribution are driving demand for large-format industrial buildings.

Where the work is

Multi-unit industrial estates for smaller occupiers (5,000 to 20,000 sq ft units) are the bread and butter of speculative development. Every regional developer, from Segro to Prologis to Panattoni, has a pipeline of these schemes. The groundworks package is the complete external works: site strip, drainage, foundations, roads, car parks, kerbing, fencing, and utility connections.

Cold storage facilities are a growth area driven by the demand for temperature-controlled logistics. These are specialist groundworks jobs: insulated foundations to prevent ground heave, heater mat systems beneath freezer slabs, heavy-duty floor slabs for high-bay racking systems (FM2 or FM3 flatness to TR34). If you can demonstrate experience in cold store groundworks, you’re in a shrinking pool of contractors who understand what’s required.

Vehicle storage and auction sites continue to expand. Companies like Copart are developing new sites across the UK, requiring heavy-duty flexible and rigid pavements, perimeter security, drainage, and lighting infrastructure. We’ve delivered multiple sites for Copart, including a 26-acre operations centre in Dunfermline with 27,500m3 of earthworks.

BIM is coming down the supply chain

Building Information Modelling has been mandatory on central government projects since 2016. For most groundworks subcontractors, it’s been something the main contractor dealt with, and your involvement extended to receiving PDF drawings extracted from the model.

That’s changing.

What BIM level 2 means for you now

Digital drawing issue. Increasingly, drawings are issued through Common Data Environments (CDEs) like Autodesk Construction Cloud, Asite, or Viewpoint. You need to be able to log in, download the latest revision, and confirm receipt. If you’re still asking the site manager to print you a set, you’re behind.

As-built information. On BIM-mandated projects, the client wants as-built data in a structured digital format, not a red-line markup on a paper drawing. For drainage, that means providing invert levels, pipe runs, and manhole schedules in a format that can be imported back into the model. GPS survey data from a total station or rover exports directly to this format. If your surveyor is already using GPS (and they should be), the additional effort is minimal.

Clash detection at design stage. The BIM model allows designers to identify where services cross, where drainage clashes with foundations, and where your groundworks interface with other packages. This should mean fewer surprises on site. In practice, the quality of clash detection depends on how complete the model is, but it’s an improvement on the old method of finding clashes when your excavator bucket hits a pipe that wasn’t on the drawing.

What you need to do

You don’t need to become a BIM expert or invest in expensive software. You do need to:

Get comfortable with CDEs. Accept logins, use them, download drawings from them. This is table stakes.
Provide digital as-built data. Talk to your surveyor about exporting data in IFC or DXF format.
Respond to RFIs and design queries through the CDE, not by phone or separate email chains.
Include BIM compliance in your pre-qualification submissions. Constructionline and Achilles BuildingConfidence both ask about digital capability now.

Procurement is moving online

The days of getting groundworks work purely through personal relationships are not over, but they’re shrinking. The main contractors and developers who let the big packages are increasingly using formal procurement platforms and pre-qualification systems.

The platforms that matter

Constructionline is the UK’s largest pre-qualification scheme, with over 75,000 registered suppliers. Bronze gives you basic visibility. Silver (which includes a financial assessment and a health and safety audit) is the minimum most Tier 1 contractors require before they’ll invite you to tender. Gold adds environmental and quality management assessments.

Achilles BuildingConfidence is used by several major main contractors (including Balfour Beatty, BAM, and Morgan Sindall) as their primary pre-qualification gateway. If you’re not on it, you won’t appear in their search results when they’re looking for a groundworks sub in your area.

CompeteFor is the procurement portal for public sector and infrastructure contracts. Major projects (HS2, Thames Tideway, Hinkley Point C) advertise packages here. It’s free to register.

Contractor-specific portals. Many Tier 1 contractors run their own procurement platforms. Kier uses Supply Chain Connect. Wates has its own system. Skanska uses a pre-qualification questionnaire process. Each one requires a separate registration and submission. It’s tedious, but it’s how the work reaches you.

The commercial reality

Maintaining your accreditations and platform registrations costs money and time. Constructionline Silver runs to around £700-£1,200 per year depending on turnover. Achilles BuildingConfidence is similar. CSCS cards for your workforce, SSIP health and safety assessments, and annual audits all add up.

But the alternative, relying solely on word of mouth and existing relationships, limits your pipeline to whoever already knows you. The firms growing their order books are the ones who treat pre-qualification as a business development activity, not an administrative burden.

The skills gap is real and getting worse

This is the one that every civils firm owner worries about, and nobody has a convincing answer for.

The numbers

The average age of a UK construction worker is now over 50. The CITB estimates the industry needs to recruit 225,000 additional workers by 2027 just to meet current demand. For specialist trades like groundworks, the shortage is acute. Finding an experienced 360-degree excavator operator, a competent drainage layer, or a site agent who can run a civils package independently is genuinely difficult.

What’s causing it

Retirement. The generation of groundworkers who started in the 1980s and 1990s are leaving the industry. They learned on the job, gained decades of experience, and there’s nobody behind them with equivalent knowledge.

Competition from other sectors. A 25-year-old with practical skills can earn more driving an HGV than laying drainage. Logistics, warehouse operations, and rail maintenance all compete for the same labour pool.

Training gaps. The apprenticeship system in groundworks is thin compared to other trades. There’s no nationally recognised “groundworker” apprenticeship that covers the full range of skills (setting out, excavation, drainage, concreting, kerbing, surfacing). Most people learn on the job from experienced operatives, and those experienced operatives are the ones retiring.

Image. Construction has a perception problem with younger workers. Outdoor work in all weathers, physically demanding, early starts. The industry hasn’t done a great job of showing that a skilled groundworker can earn £45,000-£60,000 a year, run their own gang, and progress to site management within a decade.

What you can do about it

Invest in your existing people. Send your operators on advanced courses. Put your foremen through the CITB Site Management Safety Training Scheme (SMSTS). Pay for your labourers to get their CPCS or NPORS plant tickets. Every person you upskill is one fewer you need to recruit.

Take on apprentices. Yes, it’s slower than hiring experienced people. Yes, they make mistakes. But a labourer you train for three years and treat well will stay with you for ten. An agency operative you hire on Monday will leave for an extra £20 a day on Friday.

Pay properly. The firms losing people are the ones paying 2019 rates in a 2026 market. Check the BCIS labour rate indices and the Build UK annual rates survey. If your rates are below the median, your best people are already looking elsewhere.

Offer progression. Show your workforce a career path. Labourer to machine operator to ganger to foreman to site agent. Each step with more responsibility, more money, and more autonomy. People stay where they can see a future.

What actually matters

The future of civil engineering in the UK isn’t about robots or AI or 3D printing (not yet, anyway). It’s about three things:

The work is there. Renewable energy, industrial logistics, housing, and infrastructure. The pipeline is full. The challenge is winning it, delivering it, and finding the people to do it.

The route to market is changing. Pre-qualification platforms, BIM compliance, and digital procurement are replacing the old ways. Adapt or get left behind.

The people are the bottleneck. Every other problem in construction (programme delays, cost overruns, quality issues) traces back to not having enough skilled, experienced people. The firms that invest in their workforce will have a structural advantage for the next decade.

Everything else is noise.
