We were commissioned by ACAI Group to replace a badly corroded external staircase at the rear of a property in Harrow.
The existing stair, being probably in excess of 20 years old, did not conform to current regulations and nor could the replacement stair due to the space restrictions, so permission was granted by Building Control to replace ‘like for like’ in terms of tread goings and risers.
At the time our in house drafting facilities were very busy on other projects so the design work and drawings were carried out by Sam Thewsey of DSD Ltd.
As this was an office access stair, we carried out the removal and replacement over 4 long days, partly over a weekend, to minimise disruption to the businesses.
The new stair stringers, treads and balustrade were hot dip galvanized for durability.
