Role of
The Client In Design And Construction
Above Article points out
that administration of building construction is difficult, as a result of which
some clients, or owners, engage a construction manager or construction program
manager to act as the owner’s authorizing agent and project overseer. The
reasons for the complexity of construction administration can be seen from an
examination of the owner’s role before and during construction.
After the owner
recognizes the need for a new building, the owner establishes project goals and
determines the economic feasibility of the project. If it appears to be
feasible, the owner develops a building program (list of requirements), budget,
and time schedule for construction. Next, preliminary arrangements are made to
finance construction. Then, the owner selects a construction program manager or
an architect for design of the building. Later, a construction manager may be
chosen, if desired.
The architect may seek
from the owner approval of the various consultants that will be needed for
design. If a site for the building has not been obtained at this stage, the
architect can assist in site selection. When a suitable site has been found,
the owner purchases it and arranges for surveys and subsurface explorations to
provide information for locating the building, access, foundation design and
construction, and landscaping. It is advisable at this stage for the owner to
start developing harmonious relations with the community in which the building
will be erected.
During design, the owner
assists with critical design decisions; approves schematic drawings, rough cost
estimates, preliminary drawings, outline specifications, preliminary cost
estimates, contract documents, and final cost estimate; pays designers’ fees in
instalments as design progresses; and obtains a construction loan. Then, the
owner awards the general contract for construction and orders construction to
start. Also, the owner takes out liability, property, and other desirable
insurance.
At the start of
construction, the owner arranges for construction permits. As construction
proceeds, the owner’s representatives inspect the work to ensure compliance
with the contract documents. Also, the owner pays contractors in accordance
with the terms of the contract. Finally, the owner approves and accepts the
completed project.
One variation of the
preceding procedure is useful when time available for construction is short. It
is called phase, or fast-track, construction. In this variation, the owner
engages a construction manager and a general contractor before design has been
completed, to get an early start on construction. Work then proceeds on some
parts of the building while other parts are still being designed. For example,
excavation and foundation construction are carried out while design of the
structural framing is being finished. The structural framing is erected, while
heating, ventilation, and air-conditioning, electrical, plumbing, wall, and
finishing details are being developed. For tall buildings, the lower portion
can be constructed while the upper part is still being designed. For large,
low-rise buildings, one section can be built while another is under design.
