Project summary
Removal of internal load bearing wall and installation of supporting steel beam to ground floor lounge
Property is located in Catford, South East London. The property is a Victorian terraced house. Built of brick construction with solid walls. The internal wall was located between two existing rooms.
The brief was to create an internal opening between the rooms to open the space so the client can let more light into the back room which was North facing and suffered from poor lighting.
Methodology
structural calculations are prepared based on a site visit from our surveyor. Based on these working items we procure the correct steel beam ready for installation. The opening is then prepared.
The load bearing wall was constructed of single skin brickwork with internal timber rafters supporting the first floor bedroom wall partition above.
At this stage, we can also observe the loading from the main roof is borne onto this partition so care must be taken with the temporary acrow props installation.
Removal of existing load bearing wall and temporary structural supports erected. Installation of 1No 178 x 102 x 30 per engineering specifications.
Due to the mixture of timber and brick supports, we have to install a 100mm x 100mm timber post to bear the load of one end of the steel beam. This is common practice in properties of this types which have the curved wall leading into the ground floor hallway.
This choice of support required external battens to be fitted with boarding and mesh to hold a mortar render to match the existing external wall finish.
Structural props remain in place to support the steel beam once installed to allow the curing process of the pad stones to settle with minimum shrinkage and movement across the span of the steel beam.
The steel beam is checked with a laser level during the curing process after the pad stones have been set to ensure minimal shrinkage and the beam remains level.
Internally the steal beam is battened and covered with Gyproc fire line board to meet Uk Building regulations for fire proofing means of escape in residential properties.
Internal making good is carried out and with the steel beam and walls plaster skimmed. The section of floor where the load bearing wall was removed is then made good in patch to match the existing boards.
