ABSTRACT

Everyday life on bridge construction sites is commonly characterized by enormous pressure due to time and costs as well as difficult logistic requirements. Modern process simulation tools can be applied with increasing success. Projects are often affected by unscheduled constraints and limitations, that give reason to deviate from the formerly optimized plan, and to find ad-hoc solutions, especially in the erection phase.

In order to meet these requirements, simulation tools in the erection phase with a more specific database are needed. An approach based on accurate day-to-day data for the current project state at any time is needed. These data then facilitate the simulation of possible variations for ongoing optimization. At first, it is necessary to determine, which choice of data is significant and actually needed for evaluating the day-to-day status in bridge construction progress. Secondly, the required data must be captured as efficiently as possible during the ongoing working activities.

CHAPTER ONE

1.0     INTRODUCTION

Construction has turned into an ever more complex mesh of relationships between increasingly accelerating processes, decisions and actions. At the same time, however, there is a development toward sustainable

design that leads to buildings providing the best possible

connection of functionality and architecture, energy
effi ciency and healthy construction materials that can
be recycled while at the same time also achieving the
best possible economical benefi ts.

Following its modest beginnings, the Drees & Sommer
corporation has grown in this area and for over 35 years
now has been signifi cantly contributing to the develop-
ment of modern project management while always
putting an emphasis on innovation when it came to
management method. On this basis, the third edition
of this book has been completely reviewed and now
constitutes the current status of development.

The key to successfully handling current complexities
and dynamics is with the project managers who are
completely at home in the subject of contents and inter-
relations between planning and construction implemen-
tation and who master state-of-the-art management
methods. If, in addition to this, constructive cooperation
between all participants in the team can be achieved,
there are the best possible chances of achieving the
optimum possible project result.

At major structural engineering projects, project

p

articipants from the most different areas of interests

a

nd knowledge gather in one place: Architects, project

managers and specialized planners, representatives

o

f the client, of the relevant authorities and also from
the building and construction industry. Communication
diffi culties cannot be ruled out in such a heterogene-

o

us circle. It is, hence, one of fi rst aims of this book,

to outline both the participants and the process of

structuralengineering projects – for planning and con-

struction – by using striking examples to describe them

clearly. Furthermore, the essential management tasks

a

nd possible management variants are explained.

With this book, I would like to thank all employees

a

nd partners of the Drees & Sommer group who have

a

ccompanied me over the course of this development

a

nd have fundamentally contributed to the contents

a

nd professional implementation of the same.

Furthermore I would like to thank Ms Angela Reitmaier,
for the preparation of the layout and the illustrations,
to the stage of galley proofs ready for print, as well as
Steffen Sommer for his editing of the texts.
