This method gives us the benefit of being able to consider the dependencies between each trade involved, as opposed to traditional project completion evaluations. The documentation is also based on the property matrix so that it is easily possible to compare activities with the timetable tailored to the project structure. This allows an approach whereby target/actual comparisons are carried out, enabling later charges for additional expenditures or at least making them plausible. It locates the ‘trouble spots’ in construction activities better and quicker – the activities and areas where working hours are ‘burned’ –so that a response can be made in a timely fashion.
This all means that BMC documentation can help all parties in distinguishing justified claims for supplementary work from unjustified ones. This is something that cannot be done solely with photographs.
