Rethinking Construction
CHAPTER 3
Improving the Project Process
- Can construction learn from the successes of
manufacturing and service industry? The Task Force
believes it can. Our view is similar to that of
construction industry representatives on the Task Force's
visit to Nissan UK to see its advanced approach to
production, who wrote:
"we see that construction has two
choices: ignore all this in the belief that construction
is so unique that there are no lessons to be learned; or
seek improvement through re-engineering construction,
learning as much as possible from those who have done it
elsewhere"
- If we follow the latter approach, what is it that
construction has to learn to do differently? We believe
that at least part of the answer is that the industry has
to rethink the process through which it delivers its
projects with the aim of achieving continuous improvement
in its performance and products.
Repeated Processes
- We have repeatedly heard the claim that construction
is different from manufacturing because every product is
unique. We do not agree. Not only are many buildings,
such as houses, essentially repeat products which can be
continually improved but, more importantly, the process
of construction is itself repeated in its essentials from
project to project. Indeed, research suggests that up to
80% of inputs into buildings are repeated. Much repair
and maintenance work also uses a repeat process. The
parallel is not with building cars on the production
line; it is with designing and planning the production of
a new car model.
- The Task Force has looked at what leading clients and
innovative constructors both here and overseas are doing
to rethink the construction process. We have been
informed by our own experience and have tested out ideas
with our own construction supply chains. The documentary
evidence is scattered at present but there are a number
of pointers which indicate the same direction. These
include, for example BSRIA's study of the installation of
building services in office buildings and the Genesis
project undertaken by BAA with support from BRE. Both
studies confirmed that as much as 40% of the manpower
used on construction sites can be wasted.
- These and other studies all suggest that there are
significant inefficiencies in the constructionprocess and
that there is potential for a much more systematised and
integrated project processin which waste in all its forms
is significantly reduced and both quality and efficiency
improved.This ties in with our observation that
manufacturing has achieved performance improvements by
integrating the process and team around the product.
An Integrated Project Process
- If we are to extend throughout the construction
industry the improvements in performance that are already
being achieved by the best, we must begin by defining the
integrated project process. It is a process that utilises
the full construction team, bringing the skills of all
the participants to bear on delivering value to the
client. It is a process that is explicit and transparent,
and therefore easily understood by the participants and
their clients.
- The rationale behind the development of an integrated
process is that the efficiency of project delivery is
presently constrained by the largely separated processes
through which they are generally planned, designed and
constructed. These processes reflect the fragmented
structure of the industry and sustain a contractual and
confrontational culture.
- The conventional construction process is generally
sequential because it reflects the input of designers,
constructors and key suppliers. This process may well
minimise the risk to constructors by defining precisely,
through specifications and contracts, what the next
company in the process will do. Unfortunately, it is less
clear that this strategy protects the clients and it
often acts as an effective barrier to using the skills
and knowledge of suppliers and constructors effectively
in the design and planning of the projects.
- Moreover, the conventional processes assume that
clients benefit from choosing a new team of designers,
constructors and suppliers competitively for every
project they do. We are far from convinced of this. The
repeated selection of new teams in our view inhibits
learning, innovation and the development of skilled and
experienced teams. Critically, it has prevented the
industry from developing products and an identity - or
brand - that can be understood by its clients.
