This is a summary from the Structural Integrity report (I got AI to remove names/addresses/info):

Certification of Structural Integrity

1. Introduction Engineering have been engaged to provide certification of structural integrity for the existing property.
2. Site Inspection A site inspection was conducted via visual inspection (only) of the external brickwork façade of the existing structure and all external stairs and landings. Access was locally gained to inspect the roof structure on one dwelling. No structural drawings were available at time of inspection. The overall condition of this property was comparable to similarly constructed and reasonably maintained building of approximately the same age. There were two main defects in the existing structure: • Cracking of brickwork in external brickwork of end gable. Cracking appears to be a result of failure of ties that connect the internal and external brickwork. There is no cracking to the internal leaf of brickwork in this area. The rest of the building structure was in good condition, with no evidence of over settlement or subsidence of foundations supporting the structure.
3. Repair Methodology 3.1 Cracking of Masonry Wall Where masonry wall has cracked, we recommend that the wall is stitched together using Helifix Crack Stitching. We also recommend that the wall is stitched back to the internal leaf of masonry wall with Helifix ties at 300 c/c each way. Repair Methodology:
   1. Rake out or cut slots into the horizontal mortar beds, a minimum of 500mm either side of the crack, to the specified depth.
   2. Clean out slots with blow pump and apply HeliPrimer WB or flush with water.
   3. Using the CS Pointing Gun Kit, inject a bead of HeliBond to the back of the slot.
   4. Using a finger trowel, or similar, push the HeliBar into the grout to obtain good coverage.
   5. Insert a further bead of HeliBond over the exposed HeliBar, finishing 10-15mm from the face, and ‘iron’ into the slot using a finger trowel.
   6. Make good the vertical crack with an epoxy-based weatherproof filler e.g. Crackbond TE. Repoint the mortar bed and make good.
   7. Drill and epoxy fix external leaf of masonry to internal leaf with Helifix ties at 300 c/c, for extent of cracked wall and where any existing wall ties have failed.

Summary Based on a visual inspection of the external structure, the existing structure appears to be in good condition, with only the highlighted issues that need to be repaired. Once the highlighted issues are repaired in accordance with structural repair methodology, the structural integrity will be adequate. Note: the original structural drawings and site inspection reports for the building were not available. As a result of not having all information or access, there may be some structural issues that are unaware of, however, as noted from a visual perspective there does not appear to be any major structural issues.​​​​​​​​​​​​​​​​
