Need for As-built data
Safety is a major driving factor for maintaining as-built data. Hazardous Area Classifications and Escape route designations and plans can quickly become out of date and ineffective if not based on up to date as-built data.
Effective maintenance and management of plants/facilities cannot be undertaken without the latest as-built data and asset registers. Operating manuals, plans and preventive maintenance procedures must be constantly updated to remain useful.
EPC contractors require as-built data for retrofit and revamp projects in order to efficiently undertake FEED and design projects for the upgrade or modification of existing brown field facilities and to ensure a clash free design
Up to date as-built data is often a mandatory requirement for companies going for ISO 9000 status or for companies governed by regulatory bodies
