Client Satisfaction - Project Manager:

"To be able to show our trade partners exactly what has to happen in-situ, on-site; takes away any of the ambiguity. To visually being able to show that is a very powerful tool"

Problem

Mistakes during groundworks are usually buried with the underground services. However, as the testing & commissioning phase begins, these same mistakes always find a way back to the surface creating major disruptions to the site, including:

  • Bringing back heavy equipment
  • Creating large excavations and exclusion zones

Scope

The Main Contractor decided to implement Engineering-Grade AR inspections at the earliest stages of the project - during groundworks and underground service installations. This ensured that the associated buried utilities and services would be an accurate reflection of the model, preventing unwanted surprises during any future groundworks. For this specific scope of works, the Main Contractor used The Atom to identify and correct any issues during excavation and installation, specifically:

  • Inspection of service locations prior to excavation works commencing
  • Inspection of services during installation (correct depths, slopes and locations)

RESULTS

Using The Atom, the Main Contractor managed to catch several errors early during installation, including:

  • Drainage pipe directly under the data centre misaligned by 150mm
  • Manhole location incorrectly set out

After correcting these errors, the Main Contractor and their trade contractor updated their QA/QC process to include a pre-installation setting-out and a mid-installation walk-down using HoloSite. This proactive approach during the typically rushed early works stage would enable early detection of mistakes mitigating costs associated with rework, redesign and delays.
