Project Stages

1. Project Build Timescales
Project build timescales can vary due to the size and specification detailed but generally take between 10-12 weeks (as cited by FMB). The following details each stage of the build.
2. Crane Lift Day
The Crane Lift takes place at the outset in order to lift the structural steels and the 1st fix materials directly & safely to roof level. The Crane is essential for placement of the steels into the loft space, bearing the weight of the steels whilst they are being correctly positioned. Hand carrying of steels, common within the industry especially with sub-contracted labour, is extremely dangerous for all involved, not only for the contractor but also the householder and neighbours.

3. 1st Fix
This initial stage of the build process involves installation of structural steelwork, carpentry and external roof works. Installation of initial electrical, & plumbing works will also take place. During this period, we will also arrange for the Building Control Inspector to visit site and carry out the following 2 inspections:

  1. Steels Inspection: This is the first visit and is made to ensure the steels are correctly installed and conform to legislation. Our steels are supplied fire rated directly from our supplier.
  2. Insulation Inspection: This inspection ensures correct insulation is installed to current building code standards.

Plastering  – On completion of the 1st fix stage, including installation of new staircase (excluding stair parts) the project will be ready for plastering. In order to meet specified timescale, it is imperative at this stage that the client obtain quotations for supply of sanitary ware and ceramic tiling to shower/bathroom. We have excellent suppliers which we can recommend to help with this process.

4. 2nd Fix
Carpentry 2nd fix – Doors hung, architraves, skirting, stair parts & door furniture put in place.

Electrics 2nd fix – Light switches socket cover plates are fitted, spotlights/pendant/wall light fixtures, smoke and heat detectors are installed. Plumbing 2nd fix – Once tiling has been completed, sanitary ware is installed.
