Based on our understanding, the 8-inch diameter <br />pipeline consists of approximately 9,000 feet of dipped steel pipe installed in 1937 and the 16-inch <br />pipeline consists of approximately 9,000 feet of steel pipe installed in 1978. The pipelines extend <br />between the Bayshore Freeway and the Seaport Center and are adjacent to the salt evaporation <br />ponds on the east side of Seaport Boulevard. <br /> <br />The record drawings for the 16-inch pipeline indicate that an impressed current cathodic protection <br />system with two rectifiers was installed with the pipeline. One of the rectifiers, located at the pump <br />station on Seaport Court, was recently identified. The rectifier is on and is discharging current but the <br />effectiveness of the rectifier has not yet been determined. <br /> <br />The project scope of work below is based on designing and installing replacement cathodic protection <br />systems on the 8-inch and 16-inch metallic pipelines. Cathodic protection is recommended for the <br />pipelines due to the proximity of the salt evaporation ponds and the prior use of the property along the <br />pipeline alignment. <br /> <br />The scope of work is divided into two phases in order to accomplish the goal of installing cathodic <br />protection on the pipelines. Phase I will evaluate the existing condition of the cathodic protection and <br />corrosion monitoring systems for the pipelines, locate existing test stations, perform initial tests for <br />electrical continuity and electrical isolation and provide locations for excavation and installation of test <br />stations on the pipelines. <br /> <br />As discussed, V&A will retain the services of an underground contractor to expose the pipeline at 10 <br />locations. Based on recent project experience, the excavations are estimated at approximately <br />$8,000 each. We will contact three contractors to obtain bids for the excavation, backfill, traffic control <br /> <br />OAKLAND I HOUSTON <br />
