As-Building & Designer Support

A project should be closed with the accuracy it began.

A project is only as good as the information it is based upon. As-building is as equally important as all previous stages of the engineering process. If attention to detail is not given here, the next project requiring the information will undoubtedly incur increased costs. Our experienced design office can manage all aspects of the As-building process.


Instrumentation Designer Services

Our in-house Designers are available to support all our client needs from minor support within our own offices to permanent secondment to a client project team. We understand that in order to keep project costs down our workforce need to be dynamic and adaptable whilst maintaining a high level of service and quality. Offering a full range of control and instrumentation deliverables including but not limited to:

  • Site Surveys
  • Loop Diagrams
  • I/O Schedules
  • Termination Diagrams
  • Cable Schedules
  • F&G Layouts
  • Block Diagrams
  • Cable Routing Diagrams
  • Instrument Layouts
  • Instrument Hook-ups
  • Bill of Materials
  • Destruct Drawings

    Project As-building

    All As-building packages are initially assessed by our engineers to ensure there are no technical concerns with the information presented. Once assessed the drg’s are As-built by CAD operatives, checked by discipline designers and finally approved by the engineers. Anomalies found within the information supplied will be documented and tracked through an agreed formal process to ensure resolution, should it be required our team are on hand to travel to sites to retrieve the information.


    Ad-hoc & Legacy As-building Work

    Clients often manage minor modifications at site and hand mark drg’s to reflect the changes. Utilising the same methods as Project As-building we can manage all types of Ad-hoc and legacy As-building requirements.


    Legacy Documentation Housekeeping

    Many forms of legacy documentation exist only in hardcopy, aperture cards or microfiche slides. Often stored at site in technical libraries the retrieval is very time consuming and expensive. Utilising modern software techniques we are able to translate, redraw, reformat, index and upload any forms of legacy documentation making them available for all to see in our clients Data Management Systems.
