Add the following text:

"In the event the plans show the location of certain utilities

and/or structures both above and below ground, these locations

shall not be taken as conclusive. Verification to the

satisfaction of the Contractor of the exact location and

condition of all utilities and/or structures, whether shown on

the plans or not, shall be the responsibility of the

Contractor. The Contractor shall note that other utilities

and/or structures may exist within the project limits. No

additional costs shall be incurred by the City for utilities

which are not shown on the project plans and need to be

crossed, unless the utility substantially affects the line

and/or grades of the sewer or water piping. Prior to the

start of construction the Contractor shall contact Digger's

Hotline to have all existing utilities marked.

To avoid clogging or damaging water service laterals with

water softener materials at users not equipped with backflow

blocking check valves, the Contractor shall shut off the water

supply at the curb stop or at the water meter before

excavating across an existing water service lateral, before

disconnecting a service lateral from the existing main, and

before causing the loss of positive pressure in any water

service laterals or water mains. The Contractor shall notify

the water service user in accordance with the requirements of

Section 408.3.2 of the City's Standard Specifications. The

Contractor shall reopen the shut off valve after the water

service lateral is exposed and protected during the excavation

crossing.

If the Contractor's operations accidentally disrupt water or

sewer service to a user, the Contractor shall restore that

user's service immediately after such disruption occurs. All

service disruption restoration work associated with such

accidental disruption shall be performed by the Contractor at

no cost to the City."

b. Eight (8) feet if the water and sewer laterals are

not installed concurrently (during the same

construction project),

c. When the water and sewer laterals are installed

concurrently and the water lateral is less than 2.5"

diameter, the minimum horizontal separation of the

centerlines shall be:

1. thirty (30) inches, or

2. less than thirty (30) inches provided that the

bottom of the water pipe is at least twelve

"Water from dewatering operations shall not be directly

discharged into any existing rivers, creeks, storm sewer systems,

wetlands, etc.. Silt from dewatering operations shall not be

allowed to enter any existing rivers, creeks, sewer systems,

wetlands, etc.. The Contractor’s dewatering operations shall

conform to the requirements of Section 802.7 of the City’s

Standard Specifications. Any silt that gets into existing

rivers, creeks, sewer systems, or wetlands, etc., shall be

removed by the Contractor at no expense to the City. The

Contractor shall advise the Engineer at the time of the

preconstruction meeting of how he intends to handle dewatering

and control sediments from the dewatering operations."

WSWS 2.6.0 BACKFILLING

WSWS 2.6.1 Excavated Material for Backfill

Delete the entire text of this section and replace with the

following text.

"Native material excavated from a trench may be used for

backfilling in trenches when approved by the Engineer, provided

the native material meets the requirements of WSWS 8.43.5. If

used, native material shall be free of frozen materials or of

materials larger than six (6) inches in diameter. If detrimental

materials are encountered during excavation of the trench, the

Contractor shall separate suitable material from unsuitable or

rejected material. All unsuitable or rejected material shall

become the property of the Contractor and shall be properly

disposed of by the Contractor.

When the Engineer rejects native material (or a portion of the

native material) for backfilling trenches, the Contractor shall

be compensated for furnishing and placing granular backfill

material, as described below, at the unit price contained in the

Contractor's original bid proposal. The granular backfill

material shall conform to the requirements of WSWS 8.43.4.

If the deficiency of backfill materials is caused by improper

protection of the trench or by improper compaction methods (as

determined by testing procedures standard to the industry), the

material needed to make up the deficiency shall be furnished and

installed by the Contractor at no additional cost to the City.

If a bid item for "Furnish Granular Backfill Material" is

included in the Bid Proposal, it is included for the sole purpose


of determining a unit price for granular backfill should the City

Engineer determine it to be necessary as described above. The

Contractor, by way of this provision, acknowledges and agrees

that excavated material is to be utilized for backfill material

and determination for the necessity of, and payment for, granular

backfill material is at the sole discretion of the City Engineer.

The unit price for "Furnish Granular Backfill Material" shall

include all costs associated with excavating, hauling and

properly and legally disposing of the detrimental material

offsite; furnishing, hauling, placing, and compacting granular

backfill material; and all equipment, materials, tools, labor,

supervision, supplies, and other incidentals necessary to

complete the work. The Contractor shall provide the Engineer

with all load tickets for all granular backfill material placed

as backfill during construction. The Contractor shall provide

the Engineer with a Proctor and sieve analysis report on the

granular backfill material for review and approval prior to any

backfill material being placed. Measurement and payment for

"Furnish Granular Backfill Material" will be made per ton placed.

If a quantity for granular backfill material is included in the

Bid Proposal, the quantity and unit price might be used in

evaluating the bids and in recommending which Contractor should

be awarded the contract. The actual quantity used will likely

vary significantly from the quantity in the Bid Proposal.

WSWS 2.6.2 Granular Backfill


"The bid price for sewer and water main construction shall

include the cost of furnishing and installing the granular

backfill in trenches. The granular backfill shall conform to the

requirements of either WDOT 209.1 to WDOT 209.3 for gradation

number 2 or of WSWS 8.43.4. The use of crushed asphaltic

concrete pavement (a.k.a. millings) for backfilling of trenches

for water and sewer pipes is prohibited."

WSWS 2.6.3 Granular Backfill Credits

Delete the entire text of this section.

WSWS 2.6.5 Support of Underground Structures

Delete the entire text of this section and replace with the

following:

"Concrete backfill or cellular concrete which conforms to the

requirements of WSWS 8.35.4 or 8.35.5, respectively, shall be

used to support sewers, building sewers, water mains, and other

utilities crossing trenches. The minimum dimensions around a

utility crossing the pipeline that shall be backfilled with

concrete backfill or cellular concrete shall be from twelve (12)

inches below the utility to half way up the utility and twelve

(12) inches on each side of the pipeline along the section of the

utility exposed.

All costs associated with supporting, protecting, and backfilling

around existing utilities located near and/or across the pipeline

as described above shall be included in the unit prices for the

pipeline. Any damage caused to any existing utilities during

work on the project shall be repaired and/or replaced by the

Contractor at no expense to the City."


WSWS 2.6.7 Placing of Backfill


"If the Special Provisions or the Engineer allows the

Contractor to use pea stone, stones, or material that contains

a large percentage of voids for bedding or backfilling within

paved areas (or areas to be paved) at manholes, catch basins,

valve boxes, or trenches, the Contractor shall furnish and

install geotextile fabric over the top of the "high-voids"

material. The geotextile fabric shall conform to the

requirements of Section 645.2.2 of the Wisconsin DOT

specifications for Type SAS fabric. All costs associated with

furnishing and installing the geotextile fabric shall be

included in the cost of the item causing the need for the

bedding or backfill."

WSWS 2.6.8 Upper Level of Backfill

Delete the last sentence which reads:

"The Contractor shall backfill the remaining section of the

trench with excavated material."

WSWS 2.6.9 Minimum Backfill and/or Cover

The required cover above the outside top of all water pipe

shall be changed from a minimum five (5) feet to a minimum six

(6) feet.

The last two sentences shall be changed to read as follows:

"Excavated material meeting the requirements of WSWS 8.43.5

shall be used as a backfill only as allowed in WSWS 2.6.1 and

shall be deposited in maximum 12-inch layers. Each layer

shall be thoroughly compacted and subject to density testing

by the City."
