Tashev Engineering Ltd
CHS (Circular Hollow Section) Piling and Sheet piling precision setting out
At Tashev Engineering Ltd, we specialise in high-precision setting out and the production of accurate as-built surveys. Our expertise ensures that all works are positioned and recorded in strict accordance with design specifications, industry standards, and project tolerances.
Using advanced GNSS technology, robotic total stations, and industry-leading survey software, we deliver reliable, verifiable data that supports quality assurance, compliance, and efficient project delivery across rail and civil engineering environments.
Our CHS piling setting out and as-builts services
- Setting Out & Positioning: Transferring design coordinates to the ground using robotic total stations, often marking pile centres with pins for drilling/driving.
- Tolerance Checking: Verifying pile position accuracy, usually within a tolerance of +/-75mm, and conucting verticality checks.
- Quality Control (QA): Monitoring pile installation, checking reinforcement cage depth (if applicable), verifying cut-off levels, and maintaining accurate records (pile logs).
- As-Built Surveys: Recording the final position and elevation of each installed pile to ensure compliance with structural plans.
From bridge foundations to trackside retaining structures, we provide expert CHS piling setting out and as-built survey solutions that ensure railway infrastructure remains stable, secure, and built to last.
