calfordseaden was employed to deliver a bespoke design for a replacement firefighters’ MRL Lift and bespoke replacement passenger MRL Lift to a 20 storey mixed use development incorporating residential apartments to the upper levels, commercial units and a nursery on the ground floor.
The firefighters’ lift was to EN81-21 & EN81-72: 2015 and passenger MRL Lift to EN81-21. The capacity of both lifts was for 9 persons (675kg), fully collective in operation. Both of the lifts needed to serve all floor levels in the building.
Works undertaken included the removal of existing pre-engineered lifts, originally fitted in 2010 when the building was first constructed.
A one stop shop solution was procured, with both electrical and builders’ works completed by the lift contractor. This included 3- and single-phase power being repositioned within an existing room between lift shafts at ground floor level. This room was also utilised to house the lift control panels, lift isolators and consumers units.
The builders work included the raising or ramping of existing floor levels by 25mm in front of every landing so that any water entering the safe area will not enter the lift well but drain away down the stairs into drains or scuppers outside of the building.
The existing lift well pits were tanked as previous history suggested these filled with sewage / contaminated water on a regular basis.
A live residential building, served by one remaining lift, key factor for the project being to retain a working lift throughout, and to ensure a timely delivered programme of works to budget.
This scheme has been highlighted as an example of best practice through the award of Demonstration Project status by Constructing Excellence, the organisation responsible for improving performance in the construction industry.
