First Fix Electrics

First fix electrics commenced.
As well as the electric cable, data cable was fed to the various locations within the property. This cable was necessary for monitoring purposes which will be done via the Wattbox controller.
Furthermore cables for telephone, cable television, and satellite were fed to all the rooms. This was to eliminate the risk of the new tenant calling in media companies and creating holes through their installation.
Most cables were drawn through existing first floor joists and through the new timber studding on the external walls. The cables were protected by metal plates to eliminate damage in the timber stud.
The draw cables within the pod structure conduit appeared to be jammed.
Boards were exposed within the pod structure to gain access. This revealed some poor jointing of the airtightness membrane within the pod structure.
We tried to address these in situ and refitted the boards after drawing the cables.
Down lighters within the pod structure ceiling were deeper than the insulated plaster board and as a result the specified down lighters could not be fitted. Another solution would need to be sought.
The MVHR ducting runs were installed as specified.
The ducting did need to run through the airtightness membrane. Great attention was paid to ensure a good airtight seal at these points. Some adaptation had to be made to the ducting runs in order to ensure a good flow and continuity to the various rooms in the property.
The utility meter cupboard doors had been manufactured incorporating insulation and twin seals to maintain airtightness.
It was assumed that the interior of the meter cupboard was not airtight because of existing gas and electricity meters etc.
