Abstract:
One from important requirements of successfully managed building
project is determining of contract parameters (mainly time and
costs) already in project preparation phase. Such consideration
requires a significantly objectified analysis of both influential parameters.
Our research is focused especially to risks resulting from construction
process acceleration. This phenomenon is in construction evident
for several years. The construction processes parameters allow the
time regulation of every operation. For all that the contractor must consider
fairly, by what measures and at which “rate” he is able to perform
the contract construction time. On the other hand the client must accept
objective time possibilities of construction and reconciliation of time parameters
between client and contractor must occur.
The paper presents an approach to reconciliation of construction time parameters
between client and contractor and affords opportunity to model
the trend of contract construction times in various projects segments. The
spatial and organizational possibilities of construction process development
in individual projects segments determines the measures for performance
of construction time similar to contract construction time as more
as possible.
Fifty five construction projects were analyzed. Considering the heterogeneousness
of their spatial and technological structure, these projects
were divided to following segments: multifunctional buildings, shopping
centres, production plants and residential buildings. Trends of contract
construction time and simulated measures impacts (construction time
shortening) were derived for all the segments.
The paper presents a possible approach to objectification of building time
parameters. The point of the research consists in estimation of expected
time limits for intended construction that are necessary for client as well
as for forward contractor.
