Brew House

Anomalies:

The following anomalies were observed during the site visit:

  • Infiltration on the staircase.

  • Water dripping from the ceiling on rainy days in one office.

  • Movement of concrete columns causing concrete detachment.

Rehabilitation:

The rehabilitation will be focused on the damaged concrete columns.

Figure 1: Brew House - Damaged concrete columns

Proceedings:

  1. Behavioural tests shall be performed to determine the causes of the damage (it is difficult to establish it from a visual inspection only), whether the concrete columns have shifted, or the beams are pulling out and if the integrity of the structure has been compromised.

  2. Monitoring tests shall be perfumed to indicate the extent of the damage and if there is still movement in the structural elements.

  3. Based on the results obtained from the tests above, a contractor shall be appointed to execute the repairs to the damaged elements using structural repair mortar and reinforce the connections. In case of a compromised structural integrity, reinforcing elements shall be added to the structure.

  4. When repairing the concrete, these steps should be followed:

    1. Select the repair method and material

    2. Prepare the existing concrete for repair

    3. Implement the repair method

    4. Cure the repaired area properly

Recommendations:

It is recommended to use an experienced laboratory to perform the tests for structural integrity (concrete resistance and movement monitoring), such as LEM, or similar approved by the structural engineer.

The contractor shall submit technical specifications of the material to be used for structural repair, for approval. In the case where additional reinforcing elements are required, carbon strips may be an option.
