The scope of section 104 contractor varies by site, but the objective is consistent: reduce ambiguity, choose a practical method, and deliver a result that holds up under real operating conditions.
We install Section 104 adoptable foul and surface water sewers for developments that must be vested with the water authority. Packages include pipe runs, manholes, connections, testing and records structured for S104 technical approval and bond release milestones.
Operational pressure or tight sequencing often makes a generic fix too risky; structured scope and delivery reduce that exposure.

When you might need Section 104 Contractor
These are the situations where this service typically adds the most value and helps prevent avoidable rework.

It is particularly useful where project teams need clear options, documented next steps, and a delivery plan that aligns with other trades and milestones. At this stage, teams usually need clear commercial options before committing to delivery windows and budgets.

Frequently Asked Questions
Do you build foul and surface water sewers for adoption?
Yes. We install adoptable pipework, manholes and connections to authority detail, with testing regimes aligned to Section 104 technical approval.
Can S104 be split from roads packages?
Yes. We can price sewers separately while maintaining interface coordination with Section 38 roads and attenuation on the same development.
What affects S104 programme duration?
Ground conditions, dewatering, utility diversions and authority inspection windows — we flag these at tender so bond release dates stay realistic.
What practical factors should be reviewed first?
Review site conditions, access constraints, and project scope early to keep scope realistic and avoid unnecessary rework.
