Structural Report: Internal and External Inspection

Letter Report: Proposed Internal and External Inspection of Front Wall and Surrounding Structure

The structural inspection report has been prepared on the instructions of N Patel and AA Patel, our clients. We have been requested by our client to carry out a site visit with a view to looking at the current condition of the front wall structure to the property and to carry out a general internal and external inspection of the property to inspect some cracking and movement that has taken place. The visual survey was undertaken on the afternoon of the 10th of February 2020.

The inspection took place both internally and externally and the weather was cold and sunny. No intrusive investigations were carried out at this stage The following other limitations in respect of this report should also be noted: The inspection was carried out from within the property at 1st and ground floor levels internally and at Ground floor level externally. The inspection was of a purely visual nature. Services within and to the property have not been inspected. In accordance with our standard practice we must point out that this report is based upon our inspection of the premises and any other information made available to us, both written and oral, which we have assumed to be correct.

This report is intended primarily for information and is to be read in conjunction with any other specialist reports and investigations. The report is for the benefit of N Patel and AA Patel, our clients. Structural Engineering Services cannot accept any liability to any third party for the whole or part of its content.

Brief Description of The Existing Property

The existing properties are five-story terraced offices located on Fournier Street, London. The property is formed of basement, ground, first and second and third floor levels with the 3rd floor level being formed within the roof structure.

The property is formed in load bearing masonry walls typically 225mm wide (Possibly wider walls may be in place as its five stories in height) with timber floors and roof construction. The internal walls are a combination of timber and masonry.
The adjacent properties are of a similar form of construction as is the rest of the street. Between No 33 and 35 is an opening which leads to the rear of the property. No 35 has been rendered and painted between ground and first floor levels with the rest of the buildings at both No 33 and 35 being exposed brickwork.

There are areas of cracking evident to the front elevation windows at ground floor level and noticeable distortion to both elevations with both areas of walls bowing at 1st floor level. There are areas of distorted masonry and cracking evident to the masonry both internally and externally this is more noticeable to No 35 where-as No 33 has been rendered which may be hiding some further structural issues. Above the windows at ground floor level to No 35 is an are of loose mortar which will eventually become free and may injure a passing pedestrian walking below.

Conclusion

Due to the level of internal and external cracking evident and localized distortion, bowing, areas of loose masonry and movement to the front walls and windows at ground floor level we would recommend the following remedial/rebuilding works are undertaken:

Partial removal and rebuilding of the ground floor wall up to 1st floor level where the main bowing within the wall is located to correct the current bowing and distortion/defects within the wall. The existing arches and masonry above it would need to be removed and rebuilt also. This is more visible to No 35 but we would assume similar defects are in place to No 33. The existing masonry and feature members can be saved and stored for later re-use.

We would also recommend that the existing walls and floors are tied/restrained at the upper floor levels and details of these proposed remedial works is attached to this report. The internal general cracks can be repaired following the remedial works being carried out.

As the building is listed, permission will need to be sought from the Historic England and the National Amenity Society and this is normally determined by the Local Planning Authority. As the proposed remedial/repair works will have an affect on the external appearance of the existing property Planning Permission may also be required prior to any works taking place.
