Where Civils Contractors Lose Time to Admin, and What to Fix First

Ask the director of a groundworks, drainage or utilities contractor where the week goes and the answer is rarely the site. It is the estimate that had to be rebuilt from an old spreadsheet, the payment application chased for the third time, the permit pack, the RAMS rewritten for a job that looks much like the last one, and the photos sitting on someone's phone when a variation is disputed.

There is no reliable national figure for the hours UK contractors spend on admin. A government study of retentions asked, then left its own survey data out because the answers about time could not be robustly interpreted.¹ What the evidence does show is where the time and money leak. This guide walks through five of those places in a typical civils business and the order we would fix them in.

Productive on site, slower in the office

Civils starts from a strong position. The Office for National Statistics found the highest level of productivity in construction is in civil engineering, above the UK average and generally around twice as high as specialised construction.² That analysis runs to 2020 and is the latest the ONS has published, and many groundworks and drainage subcontractors are classed as specialised construction, so the picture is mixed for smaller firms.

The losses sit around the work rather than in it. The Get It Right Initiative's research put the total cost of error in UK construction at around 21% of total spend, of which it estimated 6% is unrecorded process waste, alongside 5% recorded direct costs, 7% indirect costs and 3% latent defects.³ That is an expert estimate rather than a measurement, but process waste is exactly what admin that gets done twice looks like.

Construction has also been slow to adopt the tools that take this work away. The ONS reports 13% of construction businesses using AI, compared with 58% in information and communication.⁴

Quoting and tendering: hours on work you may not win

Estimating is skilled work, but much of the time goes on the unskilled part: finding the last similar job, copying rates, updating material prices and formatting the document. When costs move, rates in an old spreadsheet go stale quickly. In the Civil Engineering Contractors' Association's survey for the first quarter of 2026, 57% of firms reported higher tender prices.⁵

The fix is a priced rate library that stays current, standard build-ups for the jobs you quote most, and quote documents generated from them rather than typed. Because quoting happens every working day, it is often the first place custom software earns its keep.

Getting paid: applications, chasing and retentions

For a subcontractor, getting paid is an admin process: measure, apply, chase, reconcile, then chase the retention. It is slow even at the top of the chain. Government payment practice figures for 2025 show large construction businesses taking a median 33 days to pay their suppliers, against 32 days for large businesses overall, with 14% of their invoices paid late.⁶

The government estimates late payment costs the UK economy £11 billion a year and that 38 businesses close every day because they are not paid on time. In March 2026 it announced a 60-day cap on payment terms when large firms pay smaller suppliers, mandatory interest on late payments at 8% above Bank of England base rate, and a proposal to ban the withholding of retention payments in construction contracts, subject to consultation.⁷

Retentions have long been a problem of their own. In a 2017 government study, around 71% of contractors who had retentions held in the previous three years had experienced delays in getting the money back.¹ The stakes are high: construction had more company insolvencies than any other industry in England and Wales in the 12 months to August 2026, with 3,866 cases, 17% of those where the industry was recorded.⁸

Most of this cannot be fixed from your side alone, but the admin can. Applications built straight from measured quantities, a dated record of what was submitted and when, automatic reminders as due dates pass and a retention ledger with release dates mean nobody has to remember to chase.

Permits, RAMS and compliance paperwork

Utilities and highways work runs on permits. The Department for Transport estimated around 2.5 million street and road works are carried out in England each year.⁹ Each one needs its paperwork, and so does every job's risk assessment and method statement.

In our experience the waste is not the compliance itself, which matters, but writing similar documents from scratch. A library of approved RAMS sections, filled from the job details you already hold, keeps the judgement with your competent people and takes the retyping away from them.

From site to office: the same information typed twice

Site diaries, timesheets, plant hours, quantities and photos usually start on paper, in a messaging app or in someone's head, and are typed up later in the office. A 2023 Get It Right Initiative study found that although 90% of respondents were using common data environments, most sites still relied on email or messaging as their core way of sharing information between site and design teams, with email named by 58.8%.¹⁰ The sample was small, so treat the figures as indicative, but the pattern will be familiar.

Every retyping is a chance for an error and a delay. A single site form on a phone, used for the diary, the timesheet and the photos, can feed payroll, job costing and the next payment application without anyone keying it again. Where a judgement call is needed, such as matching a photo to a variation, an AI agent can draft the match for a person to check.

Variations and records: the admin that decides disputes

When a variation is disputed, the paperwork decides the outcome. Arcadis's 2022 disputes report found the top cause of construction disputes in the UK was poorly drafted, incomplete or unsubstantiated claims, followed by owner-directed changes, and that the average UK dispute took just under 12 months to resolve.¹¹

Both causes come down to records. An instruction logged on the day it was given, with photos, the location and the quantities affected, is far easier to get paid for than one reconstructed from memory months later.

Where to start

Do not start with software. Start by finding out where the hours actually go, then fix the process that repeats most often. For most civils firms that is either quoting or the loop from site record to payment application.

If you want a quick number first, the calculator below estimates what manual work is costing you a year. For how to weigh that against the cost of building something, read manual work versus automation ROI.

Admin is only half the picture for a growing contractor. The other half is being found and checked by the buyers who shortlist suppliers, which we cover in digital marketing for engineering companies and civils firms.
