When is this service useful?

This page helps structure an enquiry about core drilling, for example for planned service routes. It does not promise that KnaBa performs the drilling itself. Feasibility, the responsible qualified contractor and required approvals are established before any order.

  • Diameter and depth
  • Inspect reinforcement and services
  • Approval, structure and safety
Additional works by enquiry

Core drilling, service openings and other construction work are assessed for technical feasibility, qualified providers and contract terms first.

01

Possible scope by agreement

  • Identify the purpose, number, diameter and proposed location of openings.
  • Gather component type, material, thickness and available drawings for specialist assessment.
  • Separately agree access, protection of surroundings and handling of water, slurry or the drill core.

02

Prepare your enquiry

  • Provide drawings and location details; photos do not replace utility or structural assessment.
  • Clarify owner approval, required permissions and the structural contact.
  • Describe access from both sides, use of adjacent rooms and the preferred time window.

What needs prior agreement

No execution is promised without specialist assessment. Structural capacity, reinforcement, utilities and fire protection are matters for responsible specialists. Sealing, fire stopping, disposal and making good require separate agreement.

Outcome and handover

The enquiry should establish feasibility, responsibility and scope. Execution and timing can be agreed on a binding basis only afterwards.

What determines a suitable quote?

Area alone is not enough for a reliable estimate. Construction stage, materials, soiling, access, timing and agreed extras affect the work involved. A site visit or further details may be needed; the price is set in the specific quote.
