It was shown that much compensating work was undertaken by personnel of contracting
organizations during the management of construction projects when they used measured
quantity data prepared by the Clients' Quantity Surveyor. It was further shown that a
standard method for preparing measured quantity data which reflected contracting
management and construction methods could be developed if the amount and type of
compensating work was identified. This method for measuring construction work would
consequently find a use in the increasingly popular Design and Construct procurement
method resulting from the swing in investment in construction work to the private sector
which eroded the existing four-cornered Client: Designer: Quantity Surveyor: Contractor
relationship. This swing allowed entreprenurial contracting organizations to by-pass the
middle men (Designers and Quantity Surveyors) and liaise directly with the Client,
adopting the traditional design team's role in the process. This situation effectively
removed the centralised and controlled production of measured quantity data at pre-tender
stage (i.e. Bills of Quantities prepared by the Quantity Surveyor) leaving the contractor to
prepare his own measured quantity data ad-hoc.
The main objectives included researching within contracting organizations to defme the use
to which measured quantity data was put within the management functions of estimating,
purchasing, surveying, planning and site management. Determining what quantity data
should be measured for the benefit of these management functions. Field testing the
determined measurement rules with upto three live specification and drawing contracts, in
order to show that improvements could be made in the data flow and efficiency of data
management. Publishing the fmdings of the research.
Case studies within three contracting organizations were undertaken and interfaces between
and within the management functions where compensating work was undertaken were
identified. The measured quantity data required by contracting personnel for management
tasks was defmed. A set of measurement rules for Builders' Quantities was compiled and
tested on five projects, each of which was supplied by a different contractor. Some work
was published and more publications were planned at the time of submission.
It was shown during the field tests that savings of up to 50% in management staff time
could be made using a prototype set of measurement rules. It was thought that the use of
Builders' Quantities would also result in saving in construction costs and had implications
for use in decision making by higher management.
The work was documented in report form and submitted to the Science and Engineering
Research Council who awarded the project a grade of excellence, the highest possible
A Doctoral Thesis. Submitted in partial fulfilment of the requirements for the award of Doctor of Philosophy of Loughborough University.
