As a
general rule, building projects that are highly specialised, complex or
have the potential to cause significant major disruption to your ongoing
business activities should follow the traditional route.
More straightforward projects, where speed and cost certainty are
important than detailed control are candidates for contractor’s design.
If the
contractor’s design route is followed, the preparation of a fully
detailed and comprehensive schedule of requirements is critical
importance. This document
really must be “right first time” since any subsequent changes or
variations will be very expensive both in terms of time and cost.
Our specialist advice should be sought unless you are very familiar
with this work.
All
types of building project require expertise in contract administration and
project management. A formal
approach is usually the most productive, with written confirmation of
instructions and responses to requests for information, coupled with very
pro-active management of the schedule.
