Investigate early
Collect drawings and inspect structure, moisture, roof condition and installations. Allow for specialist advice where an alteration affects load-bearing elements or building services.
Make specifications comparable
Provide the same drawings and finish requirements when requesting quotations. Separate fixed scope, allowances and provisional items so differences in price can be understood.
Control changes
Agree how extra work is assessed and approved before it is carried out. Keep decisions and revised drawings in one project record and inspect important concealed work before finishing.
