As-Built Drawing Services & Record Documentation
Accurate as-built drawing preparation and record documentation for brownfield plants and post-construction projects across Saudi Arabia and KSA.
SLETEC Engineering provides professional as-built drawing services for industrial facilities across Saudi Arabia. Accurate as-built records are essential for plant safety, future modification planning, maintenance management, and regulatory compliance. Our team converts field redline markups, site survey measurements, and contractor as-built submittals into clean, revision-stamped AutoCAD drawings that reflect the actual installed condition of the plant.
Our as-built drawing service covers all engineering disciplines — mechanical equipment layouts, piping arrangement and isometric drawings, structural steel drawings, civil foundation and drainage drawings, and instrument/electrical cable routing drawings. We work from redlined IFC drawings, handwritten field sketches, or photographic records to ensure every as-built change is captured accurately and traceable within the document revision system.
For facilities with no existing documentation, SLETEC engineers can conduct site surveys, take field measurements, and produce new as-built drawings from scratch. This is particularly valuable for ageing plants in Jubail, Yanbu, Dammam, and Ras Tanura where original documentation has been lost or never existed. All as-built drawings are delivered in AutoCAD DWG format with PDF issue copies and a fully updated drawing register.
Engineering documentation prepared with reference to API, ASME, AISC, AWS, ISO, Saudi Aramco, SABIC and client project specifications where applicable.

Frequently Asked Questions
What is included in an as-built drawing service from SLETEC?
SLETEC as-built drawing services include incorporation of field redline markups into existing CAD drawings, site survey data conversion to CAD drawings, creation of new as-built drawings where no previous drawings exist, revision control updates with proper as-built revision stamps, and drawing register updates. We cover piping, mechanical, structural, civil, and electrical/instrument disciplines.
How does SLETEC handle as-built drawing updates for brownfield plants in KSA?
For brownfield as-built updates, SLETEC receives the issued for construction (IFC) drawings marked up with field changes by the site team, reviews all redlines for completeness and clarity, incorporates the changes into the AutoCAD drawing files, applies the as-built revision stamp, and reissues the updated drawing set with a revised drawing register.
Can SLETEC create as-built drawings from site surveys without existing drawings?
Yes. Where no existing drawings are available, SLETEC engineers can visit the site, perform field measurements and sketching, and produce new as-built drawings in AutoCAD. This service is commonly used for legacy equipment, undocumented plant modifications, and facilities where original documentation has been lost.
What drawing disciplines does SLETEC cover for as-built documentation?
SLETEC produces as-built drawings across mechanical, piping, structural, civil, and instrument/electrical disciplines. Typical as-built deliverables include as-built piping isometrics, as-built GA drawings, as-built P&ID revision support drawings, as-built structural drawings, and as-built equipment layout drawings.
