When You Need a Setting Out Engineer in Ealing
Setting out is required before construction begins and throughout the build for:
- Before groundwork: foundations, pile positions, service trenches
- During construction: brickwork corners, steel frames, holding-down bolts, internal partitions and gridlines
- Ongoing: verification checks and as-built surveys
Without professional setting out, errors can cause expensive rework, programme delays, and structural risks.

Rates include fully calibrated equipment (robotic total station, laser level, GPS) and travel within Greater London. London and West London rates are at the higher end of the range.
Deliverables
A professional setting out service provides:
- Physical marking (spray paint, nails, pins, profile boards) for gridlines, drainage popups, footings, brickwork corners, manholes, service covers
- Digital documentation with time-stamped photos and QA records
- Setting out report for your records
- Coordinate extraction from 2D AutoCAD drawings or 3D BIM models

Frequently Asked Questions
Q: When do I need a setting-out engineer in Ealing?
You need a setting-out engineer at the start of any construction project to mark the exact positions of foundations, walls, and structural elements from drawings. Setting out is typically required before excavations, concrete pours, and frame erection.
Q: What accuracy can I expect?
Modern setting-out engineers achieve ±3mm accuracy for primary control and ±5mm for structural elements using robotic total stations. Confirm your specific tolerance requirements when booking.
Q: What drawings do I need to provide?
Provide structural and architectural drawings (CAD or PDF), grid coordinates, benchmark data, and any site-specific requirements. The more detail you give upfront, the more accurate the setting out will be.
Q: How far in advance should I book?
Booking is typically possible with 24–48 hours notice. For larger or more complex projects, allow extra lead time.
