Self-build home: Construction
The construction stage is the process of constructing the works described in the design drawings and specifications. At the end of the stage, the self-build home should be ready for occupation, although the contractor may be required to return to the site, even after occupation, to rectify any defects that appear.
Throughout this stage, it may be necessary to procure items outside of the construction contract that will be required to occupy the home, such as; furniture, kitchen equipment, ICT equipment and so on.
Be aware that whilst self-build clients are ‘domestic clients’ for the purposes of the Construction (Design and Management) Regulations, they can attract health and safety duties under Part 4 of the regulations if they control the way in which construction work is carried out. See CDM for self-builders and domestic clients for more information.
- Ensure site induction talks are carried out, explaining key safety issues and site organisation.
- Introduce a signing in and signing out book for all personnel.
- When appropriate, issue notices for each trade contractor to commence work on site along with instructions regarding phasing and sequencing of the work.
- Co-ordinate the preparation of any additional information required by the trade contractors for construction.
- Where there are proposed variations to the agreed works the self builder should give careful consideration to costs that may be incurred and should assess any alternative options.
- Regular inspections should be carried out and progress photos taken. In particular, photograph defective work before any remedial works are carried out and record the date the photos were taken.
- There should be regular construction progress meetings to assess progress against the programme, resolve design issues, inspect samples, and discuss the organisation of the next stage of the construction works.
- It is important to keep all contractors and suppliers informed about the progress of the project so they are able to plan their manufacture and installation works before receiving a notice to commence work. They will have a number of clients to satisfy and are likely to favour those that allow them to maximise their efficiency.
- Visit major supplier’s factories to check work is in progress and products are as ordered.
- Regular payments must be made to contractor(s) in accordance with the requirements of the contract.
- Throughout the project gather any product literature supplied with goods. File these in preparation for creating an operation and maintenance manual.
- Co-ordinate the utility companies to install meters and connect the permanent services.
- As the construction nears completion, agree procedures for inspections, commissioning, and testing building services.
- Ensure contractor(s) rectify any defects that become apparent during commissioning, testing and inspection procedures.
- Arrange for final inspection of the works by the building control inspector (or approved inspector) and arrange for them to issue a building regulations completion certificate.
- If the works (or trade contracts) are complete, certify practical completion. See practical completion for more information.
- Make any payments due.
- Inform insurers of completion.
