External Refurbishment of 17 No. Airey Houses

Considerate Constructors RegisteredThe external refurbishment of 17 Airey PRC houses with new structural frame, insulation, cladding, replacement roof coverings, windows and external doors and other ancillary works.

[dopts id="48"]

Refurbishment works consisted of the removal of existing PCC external cladding panels, removal of existing blown fibre cavity insulation, installation of new structural timber frames between existing PRC posts and existing structural load transfer to new frames to include new insulation and new aggregate coated, glassfibre external cladding panels, new roof covering of concrete interlocking tiles, new PVCu double glazed window units and new rainwater goods, soffits, new front door canopies and new front doors and door screens renewed in timber or PVCu.

We were awarded the Considerate Constructors Certificate of Compliance Award for the project

A Pre-Contract meeting was held between the Client, CDM Co-ordinator and ourselves to agree a schedule of works. The Client wrote to both council and private tenants to explain what would be happening and give estimated timescales for the project. As Main Contractor we also wrote to, and visited, tenants to introduce ourselves and to deliver an information sheet listing their requirements for internal and external works.
The client also wrote to adjoining private owners to enquire if they would also be interested in cladding or roofing works.
Residents adjacent to a communal grass area were contacted by the council to advise that we would be using the grass area as a site compound.

We appointed a Tenant Liaison Officer who met with tenants on a regular basis to inform them of works schedules and discuss any issues or queries they had. Tenants and carers remained in situ throughout the duration of the works necessitating extremely careful programming of works to ensure minimum disruption.

Some elements of the work necessitated special arrangements to be made with tenants over access e.g. the removal of concrete mullions/columns passing through windows.

Prior to removal the first floor ceiling joists were propped using 2Nr. adjustable props from the first floor ceiling with spreader boards situated at ceiling level and floor level. Loadings were then transferred to the concrete ground floor using a similar system of 2 Nr. adjustable props complete with spreader boards situated at ceiling level and floor level. Blocking pieces were inserted between the steel floor joists to prevent crushing or distortion. Once propping was in place the existing PCC mullions could be removed using a disc cutter. The window openings were sheeted to prevent the ingress of dust into the dwelling and where practicable wet cutting methods were used to minimise dust. The ECO beam and support columns could then be fitted ensuring they were fully wedged and bolted prior to removal of the propping system.

During this stage of the works the Site Manager arranged for the tenants to vacate the area for their safety and comfort.

Running concurrently with this contract we had also been awarded a contract from Oxford City Homes for Kitchen & Bathroom Refurbishments. Certain properties required work under both contracts therefore requiring careful planning and scheduling. A number of properties required window mullions to be removed to kitchen windows and we therefore needed to carry out the kitchen works after the external works.

With numerous sub-contractors employed to carry out works one of our primary concerns was to agree programmes for their works so they could be incorporated into the master programme. We were, during the course of the works, engaged in regular site meetings with these contractors to monitor their performance and ensure that works commenced and finished on time.

The work carried out by contractors was subject to the same procedures as directly employed personnel as such our Site Manager was responsible for verifying quality on site as outlined in the procedures contained in our ISO9001:2008 quality manual. It was his responsibility to check their materials and workmanship against the specification and industry standards. This involved regular visual inspection of the works and we would not allow subsequent work to proceed until each stage was checked and verified. The contractors representative was notified of any non-conforming work and proposals including a time scale would be agreed regarding rectification

We worked very closely with MBE Consultants on the construction of the framework for the new cladding boards, the installation of which was a very complex procedure.

The sequence of operations was of paramount importance with the transfer of load from old to new framework being critical.

Part of the work involved recladding the external PCC plank facades. The PCC planks were to be removed and disposed off site. As part of our waste management plan we segregated the PCC planks and took them to our waste recycling plant where they were crushed and reused as hardcore.

When fixing the new self finished cladding boards we were able to able to make some savings. The boards came in standard 1.20x2.40 sizes and by paying careful attention to setting out, treating each storey independently and particularly ensuring we started with a full width board either side of a window, we were able to use many off-cuts above and below the windows which resulted in reducing waste boards to an absolute minimum.

Tenants were given the choice of door style and a choice of colour for the cladding.
