15 KHORDAD DAM EARTH DIKE

This project was assigned on April 1993 to WEM by the management of 15 Khordad Dam as sub-contractor for exvation of 400,000 cubic meters bolders and transport them 25 Km to the lacation of the dam site to build a dike to protect the Ghom-Isfahan highway from flooding after empoundment of the dam. This rock fill embankment was 140 meters long and up to 20 maters high adjacent to the dam body and 3 meters high near the highway. The dam was located at Dalijan County near the Ghom-Isfahan Highway. The Dam construction started without suffition studies by consultant engineers ( Mahab ), so Phase 1 of project studies was being formed during the construction, therefore a lot of changes needed to be done as long as the job proceeded. One of the additional operations was to construct a dike to prevent water to flood the highway after empounding. Since the dike should be built before empoundment so the job was urgent and compulsive. WEM hired more than 40 trucks, bulldozers, loaders and mechanical shovels to do the job fast. Whole budget for this procees was 580 Milion Rials . The job was done in less than 3 months and delivered the main contractor (Sabir Company)

ALIMALAT EARTH DAM IN CHAMESTAN, MAZANDARAN


This project was a joint project between Sepano Construction Company and WEM in Chamestan, Mazandaran. WEM was in charge of project management and running the site for execution of whole work. Sepano was in charge of finanance. The project started in September 1981 and completed in Novembre 1994. . The job was to construct a 300-Meter wide at the crown and 28-Meter height reservoir dam for irrigation of 800 acres of rice farms from Amol to Noor in Central Mazandaran. The client was Mazandaran Water and Eletricity Authorities and the consultant was Consultant Engineers. The dam was an earth dam with a bitumin curtain and pure clay core and riprap cover. The job was done in three years which was 12 months delay becuase in 1995 more than 200 days were raining and the core was clay and we had to wait until the clay gains back its optimized wetness and could be compacted to 100%. The project was hand-over to the client and the lake behind the dam is now a beatiful forest park with recreational facilitis and aslo a location for geese, swans, and ducks to make nest around the lake.

GODAR LANDAR INTAKE

This project was awarded to WEM as the sub-contractor through a tender process in 1994. The main client was Ab Niroo Company but WEM client was ILBAU from Austria. The consultant Enginner was La Mayer from Germany and Moshanir for electrical works. The location of the site was 30 Km north of Masjed Soleiman in Khoozestan Providence. The project was to contruct intke structure that was 40 Meter high and a transit structure that divert the Karoon river water to the diversion tunnel. .A part of projects was trasit structure that was built between in-take and tunnel for transforming a 9-meter suare cross-section to a circle with the 9-m diameters in a 12 meter distans. The design of moldings and fabrication was a hand craft that was done perfect and exact. Even the re-bars forming and installment was an act of art. The job was done in 11 months and turned over to ILBAU and was set in operation.

GODAR LANDAR STILLING BASE

This project was awarded to WEM as the sub-contractor by avoiding the tender process because WEM had been done a great job in Intake-Structure Project and was the only experienced contractor dor that job. The main client was Ab Niroo Company but WEM client was Dalim International from South Korea and its partner Tablie-Perlit, two first grade Iranian construction firms. The consultant Enginner was La Mayer from Germany and Moshanir for electrical works. The location of the site was 30 Km north of Masjed Soleiman in Khoozestan Providence. The project was to construct stilling basin and decipation structure right in front of the diversion tunnel on Karoon River. The plan was to build 36 reinforced concrete cube blocks with 6-meter sides dimension and 2-meter depth in the basin and installing Gabions around them and fix them by piling and grouting and pinning to ground. this basin or decipator structure was to slow down the velocity and pressure of the water coming out of the diversion tunnel that was 9 meters high with a huge pressure. Most of work were done underwater and rebar installers and fromworkers worked under water to install moldings and rebars. The concrete was also poured underwater. The job was done in 100 days and turned over to the client and was set in operation.
