Building London house extension: Finally- lets build it! How to stay on time and on the budget?
Client is keen to start and builder wants to move in, to secure the job. Therefore, before we start it is well worth checking that we have everything we need for the journey:
Scope of works- Well defined scope of works does not have to be multiple pages- actually I prefer it short and concise. It needs to contain the level detail that would allow us (builders) give you fixed quote.
Construction drawings- Not all the drawings are the same. There is a difference between planning drawings and construction drawings. And these construction drawings together with the rest of the specification provide enough information for various trades involved to complete their part of the job.
Schedule of fittings - Can be defined as a list of fittings to be installed. My advise is you should do a detailed list and present it before the start.
Procurement- Procurement is simply shopping for specialist items that are outside general builders work scope. It seems like builder should know the cost of Edwardian slim glazed timber sash windows with lamb tongue profiles of various sizes. But in fact, I would advice to get a quote from specialist supplier for specific product. Suppliers might need visit the site, it will take time and test your negotiation skills . However, for you- the homeowner- it means less surprises on a budget front in a construction phase. So either you do it yourself or allow small contingency for builder to mange things for you.
Programme- Shows you when the task must start and when to complete it. Programme will help you to gauge the progress and might indicate when the client's input is required.
Contract- Read and understand the contract you are entering. It describes the relationship between builder, client(employer) and any administering parties Architects, surveyors etc. If not sure of any part do not hesitate to seek for help. Understanding the contract will help you to understand the differences between fixed costs and the ones you can vary. Trust me variations are expensive to client and headache to the builder when trying to stay on course.
If you have covered all of the above then well done! You are more ready than 90% of our clients when they turn to us with request to start the works.
Do contact us - we will be happy to help!
