Converting an existing commercial building into a data center requires more than equipment upgrades. Behind the mechanical systems, cooling infrastructure, and new piping routes, there are often major coordination challenges within the existing structure.
For this project, the building required extensive piping to support the data center cooling system. To route the new plumbing down toward the parkade, more than 500 core holes had to be completed through existing suspended concrete slabs.
The work required more than drilling. It required GPR scanning, as-built reinforcement mapping, layout coordination, structural review, trade coordination, and careful coring execution.
Project Type: Commercial building conversion to data center
Scope: GPR scanning, reinforcement mapping, layout support, and 500+ core holes
Structure: Existing suspended concrete slabs
Slab Thickness: Approximately 10 inches to 18 inches at slab ends
Purpose: Piping and plumbing penetrations for data center cooling systems
The goal was to complete a large number of penetrations while minimizing damage to the existing reinforcement and maintaining coordination between the structural engineer, general contractor, plumbers, and other trades.
Due to the confidential nature of the project, opportunities for on-site photography were limited, so the available images provide only a brief visual reference to the work.
On paper, the scope may have looked simple: drill more than 500 holes.
In the field, it was much more complex.
Each core location had to be reviewed against the actual reinforcement inside the slab. Many of the ideal plumbing locations conflicted with existing rebar, which meant the team could not simply follow the original layout without review.
The challenges included:
This required a practical workflow where scanning, engineering review, layout adjustment, and coring all worked together.
RapidCrete began by scanning the slab and mapping the actual reinforcement conditions through the building.
The purpose was to provide the structural engineer with reliable as-built information, including:
In thicker slab areas, double-sided GPR scanning was used to improve confidence in the findings. This was important because the slabs varied in thickness, with some areas reaching approximately 18 inches.
The scanning results allowed the engineer to compare the actual field conditions with the available drawings and decide which locations could remain, which locations needed to move, and where reinforcement compromise had to be minimized.
One of the most important parts of the project was the back-and-forth coordination between RapidCrete, the structural engineer, the GC, and the plumbing team.
Many ideal core locations were not suitable once the reinforcement was mapped. In those cases, RapidCrete helped identify alternate locations and communicate layout changes so the work could move forward without unnecessary damage to the structure.
The coordination included:
This made the project less about isolated tasks and more about keeping the whole construction sequence aligned.
RapidCrete’s role combined technical assessment with hands-on execution.
The approach included:
By handling scanning, layout assistance, communication, and coring together, RapidCrete helped reduce coordination gaps and gave the project team more control before drilling started.
The work followed a coordinated sequence:
This sequence helped the GC, engineer, plumbers, and other trades work from better field information instead of assumptions.
RapidCrete completed more than 500 core holes through the existing suspended slabs with zero incidents.
Key results included:
The success of the project came from combining scanning, reporting, layout coordination, engineering communication, and coring execution into one controlled process.
A large number of holes does not make the work routine. When coring through existing suspended slabs, every penetration has the potential to conflict with reinforcement.
Existing drawings are helpful, but field scanning provides the information needed to understand what is actually inside the slab.
When core locations affect the structural engineer, plumbers, GC, and other trades, early coordination helps prevent rework and keeps the project moving.
RapidCrete’s ability to combine GPR scanning, layout assistance, reinforcement mapping, and coring helped simplify a complex scope for the project team.
This project highlights the importance of planning before coring, especially in existing structures where reinforcement locations can vary from drawings.
RapidCrete supports clients with GPR scanning, reinforcement mapping, core layout coordination, and concrete coring for complex commercial, industrial, and infrastructure projects.
