Written Scheme of Investigation (WSI)
What is it?
The Written Scheme of Investigation (WSI) is a key document which details our fieldwork and post-excavation methodologies for the mitigation of Heritage constraints within the Planning system.
The WSI is prepared by our Heritage Consultants generally in response to a project brief issued by the Local Authority Archaeological Officer.
It identifies known and potential archaeological deposits and features and suggests the most innovative, relevant and cost-effective methodology for the creation of robust cost-effective solutions to Heritage constraints within the development.
We produce Written Schemes of Investigation for all types of Heritage work, including archaeological watching briefs (archaeological observations), evaluations and excavations, in addition to historic buildings work and, as required, for non-intrusive survey work.
Our WSIs meet the requirements of Local Authorities and are of the highest professional standard.
Before preparing a WSI, our Heritage Consultants will liaise with relevant Local Authority parties, Heritage bodies (as required) and clients to ensure the most effective methodology is implemented for the timely and cost-sensitive discharge of planning conditions.
What Happens Next?
Work proceeds in accordance with the approved WSI.
