<title>ABSTRACT</title>
<p>In this study details of structure of Shahr-e-Bijar concrete-faced rock-fill (CFRD) in
Guilan (a province in the north of Iran) and the reasons to select CFRD are presented.
To select CFRD first by investigation of 18 different types of dam based on local
availability of materials and the ability of constructing by available technology (both
Iranian and foreign available technology) six types of them were selected for value
engineering. By attention to construction costs, execution time, durability, reliability
and performance and ease of construction and operation; and also, the importance
coefficient for local government were selected for value engineering. After that 3 types
of dam structure (vertical clay core dam, asphalt core dam, and CFRD) had maximum
scores. Finally, rock fill dam with concrete surface is selected because despite being
more expensive in some cases than other options, it could be considered as a successful
dam construction option in Iran because the construction needs no foreign technology
and its technology of construction and materials are available. On the other hand, the
necessary time for the project is 24 months. The main objective of this project is to
avoid time loosing because of materials availability and local technology that needs no
finance transferring and no foreign contract that may not be affected by some political
condition that delays the project.</p>
