MEETING DATE: September 18,1996
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council approve the plans and specifications for the above
project and authorize advertising for bids.
BACKGROUND INFORMATION: This project consists of trenching and installing approximately 2,200
lineal feet of various water mains, sewer pipes, and storm drain pipes,
bursting and upsizing 1,400 linear feet of existing
6 -inch sewer pipe in four alleys to 8 -inch sewer pipe, and other
incidental and related work as shown on the plans and specifications for the above project. The limits of the
project are as follows:
Alley south of Pine Street, Church Street to School Street (Sewer)
Alley south of Oak Street, Church Street to School Street (Sewer)
Alley south of Walnut Street, School Street to 200 feet east of School Street (Sewer)
Alley south of Elm Street, Church Street to School Street (Sewer)

This project is considered part of the Downtown revitalization. It improves major underground utilities before
the installation of the new sidewalk, pavement, and landscaping in the Downtown area. The "bursting" work
involves a specialized subcontractor utilizing a proprietary process in which hydraulic equipment expands
'bursts' the existing pipe and an larger polyethylene pipe is pulled through. The advantages of this method are
described in the attached memo. The specifications also include restrictions to minimize impact to business
operations.
FUNDING: The money for this project will be coming from the Water, Wastewater and Storm Drain funds.
A recommendation for appropriations will be made at the time of award.

To: City Engineer
From: Associate Civil Engineer
Date: September 11, 1996
Subject: Advantage of using Miller's Xpandit Pipe
Advantage of Xpandit Pipe over other pipe bursting methods (Use of hydraulic power
instead of air hammer or pulling a bull head):
1. Reduce noise in the working area because no air compressor is needed.
2. No vibration which can damage near -by underground utilities (especially water
lines).
3. Use of constant monitored hydraulic power instead of brutal force, the result is more
uniform and predicable.
4. The diameter of the expanded cavity can be adjusted according to the new larger
pipe diameter.
5. The installers are certified by Miller Pipe Corporation to ensure proper operation of
the equipment and less problem in finished product.
