2006 Cured In Place Pipe (CIPP) Project

Final Report

July 21, 2006

 

 

The 2006 CIPP Project work area was concentrated on downtown Massachusetts between 6th and 11th Street and in the Old West Lawrence neighborhood area. The city sewer mains in these areas were installed in the early 1930s and were constructed of vitrified clay pipe. The pipe sizes ranged from 8” to 10” in diameter.

 

I-Con was the contractor on the project. I-Con began work on April 18, 2006, pre-cleaning, televising and installing liners along Massachusetts Street downtown.  The lining work downtown was done after 11 p.m. each night to minimize disruption to business, and was completed before the water main project began.  I-Con then mobilized into the Old West Lawrence area and also added a line at 17th & Massachusetts. The entire 2006 CIPP Project was completed July 19, 2006.

 

A total of 16,481 feet (3.12 miles) of city sewer main were rehabilitated. The contracted price for the project was $459,102 plus a $9,400 change order for the line at 17th and Massachusetts for a total of $468,502. The final actual invoice cost for the entire project was $465,556, a savings of $2,946. The final cost per foot averaged $28.25 ($149,217 per mile).

 

Over all, I-Con did an excellent job again this year, working very well with the businesses downtown to minimize disruptions (such as providing portable restrooms for customers, minimizing traffic disruptions and answering project questions). There were a couple of incidents where water in a bathroom was blown out of the traps while they were jetting, but I-Con cleaned up any reported blow back.

 

 The 2006 CIPP Project was very successful and the work completed will add many more years of service to existing lines.

 

I have attached a map of the completed areas.
