Professional Road & Sewer Estimating Services Across the UK
Our road and sewer estimating services support civil engineering contractors, groundworks companies, developers and infrastructure firms across the UK. We prepare detailed estimates for estate roads, highways, sewers and wider infrastructure, including Section 38 and Section 104 schemes.
Each estimate breaks down quantities and costs for every element of the scheme, so you can save time, price accurately and submit competitive tenders.
What a Road and Sewer Estimate Includes
- Quantity take-offs: earthworks volumes, road build-up layers, kerb lengths, sewer runs and manholes.
- Material schedules: sub-base, asphalt, kerbs, pipes, chambers and covers, each listed and priced.
- Labour and plant: excavation, laying, compaction and surfacing shown separately.
- Cost breakdown: line-by-line costs with a clear summary.
- Assumptions: inclusions, exclusions and ground condition assumptions written down clearly.
Section 38 and Section 104 Estimating
Many housing developments include roads and sewers that will be adopted. Section 38 agreements cover roads to be adopted by the highway authority, and Section 104 agreements cover sewers to be adopted by the water company. We price these works to the specification on your drawings, so your tender reflects the adoption requirements.
What We Need to Start
- Road layouts, sections and construction details, in PDF or CAD format
- Drainage and sewer layouts with long sections and manhole schedules
- Levels and earthworks information, where available
- The adoption specification, where the works will be adopted
- Site investigation reports and your tender deadline
Road and Sewer Items We Price Line by Line
- Site clearance, topsoil strip and earthworks
- Capping, sub-base and road build-up layers
- Base, binder and surface course asphalt
- Kerbs, edgings and footways
- Foul and surface water sewers, by diameter and depth
- Manholes, chambers, covers and frames
- Road gullies and connections
- Attenuation tanks and storage systems
- Service ducts and utility crossings
- Reinstatement, road markings and signage, where specified
Road and Sewer Projects We Estimate
- Housing developments: estate roads, footways and adoptable sewers.
- Commercial developments: access roads, service yards and car parks.
- Highways: road construction and improvement works.
- Infrastructure: larger sewer networks and civil engineering packages.
- External works: roads, drainage and hard landscaping around buildings.
How We Build a Road and Sewer Estimate
- Review the road and drainage drawings, sections and specification.
- Measure earthworks, road layers, kerbs and footways.
- Measure sewer runs by diameter and depth, and count manholes and gullies.
- Price materials, labour and plant line by line.
- Write down the assumptions and exclusions, then issue the estimate.
Road and Sewer Terms Explained
- Section 38: an agreement for a new road to be adopted by the highway authority.
- Section 104: an agreement for a new sewer to be adopted by the water company.
- Capping layer: a layer of stone that strengthens weak ground below a road.
- Sub-base: the compacted stone layer that supports the road surface.
- Binder course: the asphalt layer between the base and the surface course.
- Invert level: the level of the inside bottom of a pipe.
- Attenuation: storing stormwater and releasing it slowly.

Frequently Asked Questions About Road and Sewer Estimating
What is included in a road and sewer estimate?
Each estimate typically includes quantity take-offs, material schedules, labour calculations and a cost breakdown, based on your drawings, specification and layouts.
What types of road and sewer projects do you cover?
We cover housing and commercial developments, highways, infrastructure, access and estate roads, drainage networks, sewer installations and external works.
How long does it take to complete an estimate?
Most estimates are completed within two to five working days, depending on the size and complexity of the project.
Do you price Section 38 and Section 104 works?
Yes. We price adoptable roads and sewers to the specification shown on your drawings.
Do you measure road build-up layers separately?
Yes. Each layer, from capping and sub-base to the surface course, is measured and priced as a separate line.
Do you provide a free sample estimate?
Yes. A free sample estimate is available, so you can see our format before you decide.
