    EPR is an Architectural Practice based in Central London. Often working on Heritage buildings with complex architectural details Scan to BIM has become the norm to fit into our Digital Technologies and BIM workflows. Scan to BIM has come a long way; however, there is a disconnect between the design teams requirements and the surveyor's approach to disrupted workflows due to unworkable models. This "old" approach is still a residue from older methodologies often creating silos of work ultimately causing delays or unexpected additional work. We found that earlier engagement and collaboration between all consultants is key for better continues workflows. Requesting Survey to BIM without clear objectives could slow down the process and leave too many interpretations of the brief ultimately realized at untimely stages of work. We found earlier sharing of information and establishing a collaborative relationship helps to speed up deliverables while creating an early warning quality assurance process. Collaborative prevents unmet expectations and helps to keep the project flowing allowing for tandem working. We will be discussing some of the benefits we have experienced. Benefits include a clearer understanding of the whole building, better visibility of existing conditions, faster inspection of existing conditions and a single source of truth reference as a complete picture. We will also discuss some of the challenges of adopting scan to BIM into our workflows. Challenges include file sizes, model compositions, and clear briefing. We have compiled a set of rules and checklist of items to help brief clients and surveyors before works start. Defining model usage after survey completion is key and better defined LOD specification rather than "blanket" descriptions is key. Including a volume strategy combined with LOD specification forms a holistic idea of survey model composition. We hope to show how collaborative working can improve this very important part of procurement. How the procurement and defined brief can allow for smoother workflows. We will discuss how we got to our lessons learned and hopefully help others in the process.
