This report summarizes the results of a cooperative Value Engineering Study of shoulder maintenance undertaken by the State Highway Agencies of Arizona, Idaho, Iowa and West Virginia under sponsorship of the Federal Highway Administration. The study was limited to unpaved shoulders. Implementation of the recommendations in the four study States would result in a total estimated improved service value in excess of $1,000,000 annually. Cost of the study was $100,000. Specific recommendations varied among the States according to local conditions. Among the recommendations are the use of larger trucks for hauling, use of side-discharge shoulder spreaders, modifications to the standard motor grader, and spot paving of shoulders in high maintenance locations. The coordination meetings attended by study participants at intervals during the project yielded significant benefits beyond their immediate function of maintaining unity among the four State investigations. These sessions provided many chances for the team members to observe and discuss equipment and methods being used by others. Useful information was exchanged in several other highway operational areas besides shoulder maintenance.

This study evaluate the value of horizontal drain in slope using value engineering process. The main focus in this study is to achieve the high value of horizontal drain in slope. The usage of horizontal drain is one of the methods that used to lower the high ground water table and hence stabilize the slope. Several elements in the slope is evaluate and the horizontal drain in the slope is studied on its value. The value of the installation of horizontal drain are investigates through sets of different types of pipes. Others components in slope such as degree of slope, drainage filter and vegetations are studied as well. The combination of different components in the slope is analyzed. Total proposed of 48 alternative design using different combination are studied with their value. From the evaluations obtained from the research, it can be concluded that the pipe that being used in the initial design which is 75mm "Class D" UPVC can be replaced by HDPE Grade PN 10 which will increase the value as much as 13.42%. However, the recommendation is given to the combination of the alternative design which give the increase value as much as 15.77 % by replacement of slope degree from 25o to 35o and 75mm "Class D" UPVC to HDPE Grade PN 10. This study also found that with the increase of slope from 25o to 35o will cost 35.32 %more on vegetation which will only increase the value by 1.85%.
