Construction Progress

To illustrate the causalities that pertain to the construction time and form the grounds of a claim, it is often not enough to conduct a one-time determination of the construction status. In order to judge a development, you cannot avoid capturing and recording this development over time.

When we do this, our documentation captures two aspects of the construction progress: firstly, the added value which is recorded as the visible work progress. Secondly, the scope of work needed to achieve the added value observed. We find the added value using an evaluation matrix. This matrix shows the quality of value-adding progress for each trade involved, using a given parameter. Unlike on-site measurements, this method does not determine the percentage of completion or other measurements that can be calculated. Rather, it evaluates the quality of the construction progress using evaluations that are measured visually.

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.
