Good project management can make the difference between a successful project completed on time or a frustrating and costly outcome affecting your house and home life.

Clients responsibility for health and safety on site. CDM regulations place responsibility on clients to appoint a principle designer and a principle contractor.

At WHS Associates in Essex we have the experience and expertise to help you out as much or as little as you want when it comes to managing your building project. We know that good project management starts with embarking on a realistic timescale that will enable the process of good design, successful negotiations with the Local Authority and the appointment of a good contractor to take place.


This starts with a realistic timescale to the project with both the client and their professional team working to realistic and achievable timescales. As a guide, these are the typical timescales for obtaining the Local Authority and statutory approvals together with identifying and appointing a reliable contractor that will complete the job within agreed timescales.


Normally for a medium sized contract, contractors will require at least four weeks to price and return the tenders. After tenders are returned, at least two weeks is normally required to appoint the contractor and start the work on site. Total of six weeks for issuing tenders.

Construction period for a two-storey rear extension is normally between 16 to 18 weeks. This provides a total of 36 weeks and does not include the design time required for the preparation of drawings and specifications.

In some instances it is possible for WHS Associates to combine the building control and tendering process which can reduce this overall period by approximately six weeks. A further reduction is also possible if the project does not require planning permission. Contact us to discuss your time frame and requirements.
