ProposalDescription: 

Proposed remediation of Brickmakerskloof Substation on erven 3499 and 3500, Central, Port Elizabeth, Eastern Cape

Expanded_Motivation: 

The Brickmakerskloof Substation appears to be older than 60 years and will therefore be considered a heritage building. The long term serviceability of the load bearing wall (eastern elevation) is unsafe for its deemed purpose and should be repaired as soon as possible. It is recommended that the wall be replaced and stabilised with two concrete columns equally spaced and formed integral with the roof ring beam. A slip joint is to be provided between the internal Tee beam and caulked up to ensure load transfer. Expansion joints must be provided between the new concrete and brickwork interfaces. All defective slip joints must be repaired.From observations, it is clear that the eastern support load bearing wall has buckled in the vertical plane. This deformation is noted between the concrete and brickwork interfaces notably at midspan. As measured onsite, this wall has deflected ~ 75 mm midspan, with the vertical height ~ 6 m, the maximum allowable deflection has been exceed by a factor of 4.5. As this is the case, this element exceeds its serviceability threshold. It was further observed that only one slip joint appears between these two interface. Excessive displacement has occurred between the concrete and brick work interfaces along the roof beam. If the load bearing wall is considered to be a vertical beam, the maximum deflection must not exceed 1/360.
