In addition to contract program development, other planning deliverables
contractors produce during the preconstruction stage include
method statement, cash flowchart/S-curve, phasing plans,
design schedule, information required schedule, procurement program,
and site layout program. All these are useful information
sources for resolving delay claims. However, an important deliverable
that is essential but is often not produced is manpower loading
graphs. The reasons given for this lapse include the concern that it
is a time-consuming and difficult exercise to perform; that it is not
often part of clients’ requirements and also not considered by parties
as a crucial requirement. Not surprisingly, the study found thatbaseline programs are hardly resource-loaded and leveled appropriately
to accurately reflect the reality of how resources will be used
on site. This practice has the tendency to affect the reliability of
baseline programs used for resolving delay claims.
