Trydan (a Welsh renewable energy company) is setting up a framework agreement to hire specialist environmental consultants for wind farm projects in Wales. They need companies to do bird surveys and habitat/soil assessments, and will call on these contractors as new wind farms need surveying. They'll pick up to three companies per service type.
Requirements
- Ability to conduct baseline ornithological surveys (bird and bat surveys for wind farm sites)
- Ability to produce professional survey reports meeting environmental assessment standards
- Expertise in habitat classification relevant to Welsh landscapes
- Capability to conduct soil and peat surveys
- Understanding of Environmental Impact Assessment (EIA) requirements for wind farm developments
- Likely requirement for relevant professional qualifications (e.g., licensed bat handlers, ornithology credentials — check full tender documents)
- Ability to work across multiple Welsh locations as call-offs are issued
- Insurance and health & safety compliance for field survey work
Key Tasks & Deliverables
- Carry out baseline ornithological surveys at designated wind farm sites (bird counts, species identification, flight path monitoring)
- Produce detailed ornithological survey reports for planning and environmental assessment
- Conduct habitat classification surveys across wind farm development areas
- Perform soil surveys and peat depth assessments on proposed wind farm locations
- Deliver habitat and soil survey reports meeting EIA and planning requirements
- Be available on a call-off basis — respond to contracted surveys as Trydan initiates them over the framework period
How to Read This Tender
- 1This is a 'framework agreement' not a single fixed contract — you're bidding to be on their approved list. You won't know the exact volume upfront; Trydan will issue individual call-off contracts (probably with tight timelines) as projects develop.
- 2The tender will likely have separate 'lots' — Lot 1 (ornithology) and Lot 2 (habitat/soils). You can bid for one or both. Each lot will have up to 3 winners selected.
- 3Check the 'call-off' terms carefully — these define how much notice you get, response times, pricing structure (fixed, daily rates, or per-site fees), and contract duration. Short notice periods are common and can strain small teams.
- 4Look for the evaluation criteria section — they'll likely score on: technical expertise, team CVs, similar project experience, price, and possibly social value (Welsh jobs, apprenticeships, etc.).
- 5Wind farm surveys are seasonal and weather-dependent — clarify with Trydan whether they expect year-round availability or specific survey windows (e.g., spring/autumn for bird migration).
Tips for Small Businesses
- Consider forming a consortium or subcontracting arrangement with a larger environmental firm — this reduces your risk if Trydan makes frequent call-offs. You can handle field surveys while a partner manages reporting and client contact.
- Emphasize local Welsh presence and knowledge in your bid — Trydan is a Welsh company and may score social value points for employing Welsh staff or using Welsh-based suppliers.
- Review the framework period carefully (typically 2–4 years). Budget for team availability and seasonal staffing even if call-offs are infrequent — you may need to retain trained surveyors on standby.
- Ask for a worked example of pricing in the tender clarification phase. Some frameworks use day rates, others fixed per-survey fees. Understand the financial model before bidding to avoid underpricing.
