Ipswich based chartered surveyors Castons was appointed by Flagship Housing Association to manage the tender process for their grounds maintenance dataset contract for their housing estate. Subsequently Castons appointed C A Design Services to help compile the necessary data on the 778 individual properties for the tender information packs.
Our cartographers created the base data for the project by scanning historic plans to create digital plans of the properties using Cadcorp GIS software. Where available relevant information was added as attributes to the plans – such as areas of ‘grass requiring maintenance’, property boundaries, hedge lengths and required heights etc.
A physical visit and survey of each site was the next stage of the project. The surveyors verified what information was correct, updated it where it wasn’t and added/amended features that were required. This data was then updated using consistent styles across all plans.
The output was the creation of the GIS dataset and PDFs of each site. This enabled Castons to extract full measurement details from the data for inclusion in the tender, enabling contractors to quote accurately for Flagship Housing’s ground maintenance programme.
