The book outlines the processes of calculating and critically reviewing
construction costs and times for clients and contractors in different
project phases. Any project or structural analysis should yield accurate
information on times, costs, and prices. The related database is more or
less uncertain depending on project complexity and the circumstances of
work performance. It is thus recommended to use ranges of key input
parameters. This approach consistently considers uncertainties within a
holistic project view, thus enhancing the plausibility and validity of
specific values. Only the integration of probabilistic methods will
allow for calculating and graphically representing the chance/risk ratio
as a crucial project variable ultimately influencing the entire
business.
This book examines the systemic modeling and consideration of
uncertainties when determining construction costs and times, and
life-cycle costs. It contains detailed descriptions of other
decision-making processes, including project preparation and planning
(developer calculation, soil survey, cost estimate), work preparation
(costing, pricing, construction time evaluation, resource
identification, comparison of construction methods, bid analysis,
contract award), and project execution (site logistics, construction
method selection, construction process planning, work coordination,
sourcing, determination of additional costs, trend analyses), as well as
for project portfolio management as a tool relevant to all phases.
