Impact assessment, its statutory timetable and who is allowed to write it
An environmental impact assessment is a statutory process with a prescribed sequence, and the procurement has to fit inside it. Screening establishes whether a formal assessment is required at all; scoping settles which effects will be examined and to what depth, usually in consultation with the regulator; the assessment itself gathers baseline data and predicts effects; and the resulting statement is published and consulted on. Each stage has a consultation period nobody can compress, so a bid whose programme omits them is not credible.
Baseline surveys are the immovable constraint. Ecological, noise, air quality and hydrological baselines can only be gathered in particular seasons or over particular durations, and a survey done outside its valid window will be challenged. Competent expert requirements apply: many jurisdictions require the assessment to be prepared by suitably qualified people and to say who they were, so the bid names specialists per topic rather than offering a firm.
The commercial risk sits after submission. Regulator and consultee requests for further information, and in contested cases a public inquiry or hearing, extend the work well beyond the statement, and expert witness attendance is a separate and expensive commitment. Tenders should be read for whether that is included, capped or excluded. Independence matters too: an assessment written by a consultant with an interest in the project proceeding is vulnerable to challenge on exactly that ground, which is why conflict declarations in this category cover the wider group and not only the team.
