The Environment Agency is looking for a contractor to design and build a new pontoon (boat landing stage) at Allington on the River Medway, repair the existing retaining wall, and carry out environmental improvements. This is a phased design-and-build project to improve safety and access for river users while meeting legal obligations under an 1911 Act.
Requirements
- Must be able to deliver phased design and build (D&B) contract — meaning you design and construct, not just one or the other
- Must comply with Upper Medway Navigation and Conservancy Act 1911 statutory obligations
- Must demonstrate experience with riverside/navigation infrastructure projects
- Must be able to work on a tidal river with associated access and environmental constraints
- Must have environmental enhancement expertise and understanding of river ecology
- Must be able to design and build to Environment Agency standards
- Must obtain necessary consents (likely planning, environmental, and navigation-related)
Key Tasks & Deliverables
- Design a new pontoon (landing stage) suitable for safe mooring of river vessels
- Construct the new pontoon with associated access and safety features
- Carry out targeted repair works to the existing retaining wall adjacent to the pontoon site
- Design and deliver environmental enhancement works to the river and surrounding area
- Ensure the design meets navigation safety requirements and public access needs
- Manage phased delivery — likely breaking the work into phases to minimise disruption
How to Read This Tender
- 1This is a 'design and build' (D&B) contract — you're responsible for both designing the solution and building it, so you need in-house design capability or a strong supply chain partnership. Don't bid if you only do one or the other.
- 2Watch for the word 'phased' — the Environment Agency is planning to break this into stages. Ask for the phasing schedule in your questions; it affects your cash flow and resource planning.
- 3The 1911 Act reference signals there are specific legal duties involved — get specialist legal advice on navigation law and EA obligations before bidding, as non-compliance could delay or stop the work.
- 4Environmental enhancement works are a significant part of this contract (not just repairs) — the buyer will likely score you on biodiversity, sustainability, and social value, not just cost. Show your environmental credentials.
- 5This is riverside work on a tidal river — factor in tidal access windows, likely planning/environmental permits, and possible protected species surveys. These slow projects down and increase costs.
Tips for Small Businesses
- Consider a consortium with a specialist civil engineer (for design) and an environmental consultant if you're primarily a contractor. D&B contracts are harder to win as a small firm alone, but partnering strengthens your bid and shares risk.
- Environmental enhancement is a big scoring area — partner with or hire someone with river habitat restoration experience. Even a small business can win by showing genuine environmental value, not just lowest cost.
- This is likely a publicly-funded EA project — check if you can claim social value points (job creation, local supply chains, apprenticeships, community benefit). Small businesses often score well here if you employ locally or offer training.
