INTRODUCTION
The Design-Build project delivery method has been
enjoying increasing acceptance in recent time . In a
questionnaire survey carried out in Saudi Arabia ,
public clients selected Design-Built as the most
appropriate procurement for their objects.
The basic feature of the design build method is that it
entails single responsibility for the entire object .
Actually, it is an expansion of the Single-Contract
System to include design as well as construction .
STATEMENT OF THE PROBLEM
The engineering and construction industry faces
formidable challenges . It suffers from low
profit margin , persistent project overruns in
schedule and budget , and it is plagued with
claim and counter claims .
Construction industry performance can be
improved by use of an appropriate project
delivery method .
SIGNIFICANCE OF THE STUDY
The study aims at developing a model for
Design-Build project delivery method
implementation . It includes all the phases for
implementing Design-Built from project
identification to contract administration .
OBJECTIVES
The objectives of the research are :
1- To get a greater understanding of the DesignBuild method.
2- To identify positive factors favoring the use
of the Design-Build method.
3- To develop a Design-Build model.
LITERATURE ANALYSIS
1- Project Delivery Method
The term “project delivery method “ means the approach used to
organize the project so as to manage the entire designing and
building process .
Following requirements fulfill the complete definition of project
delivery :
* For a project, its scope and requirements should be clearly stated .
* Method of procedure , responsibilities and obligations should be
established.
* Forming and documentation of agreement .
* Actual design and construction .
* Handing over the project to the owner .
2- Evolution of Project Delivery Method
Obtaining a project within a predefined time , cost and
quality is the ultimate goal of the clients . Also the
need for more need of financial planning and fewer
amount of contracts has increased the possibility of
looking out for new construction procurement
methods . These factors together with the need for a
greater degree of financial planning and a lesser
amount of contract administration have brought
pressure to explore new option for construction
procurement .
3- Risk Assessment in Project Delivery
Method Selection :
* Completion Risk.
* Construction Cost Risk .
* Environmental Relation Risk .
* Industrial Relation Risk .
* Technological Risk .
* Market Risk .
* Political Risk .

The Positive Factors favoring the use of Design-Build :
Single point of Responsibility.
All parties treated as professionals.
Time Savings .
Early knowledge of firm costs.
Higher Quality.
Cost-effectiveness of Design-Build.
Encourages Innovation.
Lower claims and litigation.
Reduced Administration.
Problems with Design-Build Method
* Unfamiliarity with process.
* Communicating owner’s needs in
Design-Build is different.
* Barriers in procurement and licensing
laws .

CONCLUSION



The construction industry performs unsatisfactory and
suffers from low profit margin and persistent project
overruns in schedule and budget .
The increased understanding of Design-Build project
delivery will help in successful implementation of this
fast growing project delivery method .
The use of an appropriate project delivery method is
one of the key area for the improvement of the industry.
Recommendation


The Design-Build method is gaining
popularity as an attractive and desirable project
delivery method for all types of projects .
Benefits to gained are a single source of
responsibility , reduced cost , reduced time,
innovation, established cost , reduced claims ,
improved quality , improved risk management
and improved productivity.
