Employer Information Requirements (EIR) for Geometric survey with aerial and terrestrial documentation techniques

This document is intended for incorporation by reference in UP Geometric survey working group for the documentation with laser scan and aerial and terrestrial photogrammetry techniques, for as-built conditions of the 20 buildings selected (10 buildings in the Old Strovolos core district, Nicosia and 10 buildings in the Cami Cedid and Arnaut districts, Limassol) to function as testbeds for the development of the UP platform will be created as central models to be hosted on an open source BIM software by means of importing and updating the data generated in T4.3 (WP 4). The guide has been prepared to assist the UP-project team in ensuring quality in 3D geometrical survey data. It provides guidelines for the solicitation of Geometric survey documentation techniques services and evaluation criteria to ensure that the specified requirements for the deliverables are met. Furthermore, the purpose of this document is to record the recommended quality assurance (QA) and quality control (QC) process required to streamline the procurement and acceptance of 3D laser scanned (imaging) data and photogrammetric data and their derived deliverables. The Geometrical data survey is to be used as an appendix to the base Scan to BIM.
