SUMMARY OF PURCHASING REQUEST

SCOPE OF WORK | SPECIFICATIONS

GENERAL

A. New Castle County Department of Public Works (the County) is seeking proposals for

on-call Mainline Test and Seal Pipe Grouting of Sanitary Sewer Pipes, Defects, and

Lateral Connections and Curtain Grouting for Sanitary Sewer Manholes under

contractual services as described herein at various sites countywide.

B. The Vendor shall be licensed to do business in the State of Delaware and have a current

New Castle County Contractor License.

C. The Vendor shall provide all labor, materials, tools, equipment, and incidentals as

shown, specified, and required for testing mainline sewer pipe joints, defects and lateral

connections by hydraulically applying a positive air pressure to the joints and defects,

then monitoring and recording the pressure in the void. If testing results indicate the

need for rehabilitation, the Vendor shall chemically seal the joint, defect or lateral

connection by using packer injection grouting methods which consist of pressure

injection of chemical grout into the soils outside the pipe. Chemical grouts shall be

designed to be injected into the soil surrounding the pipe, which stabilizes the soil and

forms a permanent impermeable seal called a soil ring, and into the annular space

between liners and host pipes. Adequate volumes of grout must be injected to form an

effective seal. The Vendor shall provide all labor, materials, tools, equipment, and

incidentals as shown, specified, and required for application of grout to the soil and void

areas on the exterior of buried sanitary sewer manholes by means of curtain grouting

technique.

D. The Vendor shall also provide all materials, labor, equipment, and services necessary for

traffic control, notifications to property owners and other stakeholders, controlling flow

of existing sanitary sewer (including full by-pass pumping when required), cleaning and

closed-circuit televised (CCTV) inspection of sewer pipes, quality assurance and quality

control measures.

E. Equipment utilized by the Vendor shall be maintained and calibrated as required by the

equipment manufacturer or process provider.

F. By-passing Existing Sewage Flows – When and where necessary the Vendor shall provide

for the flow of existing mainline effluent around the section or sections of pipe

designated for testing and sealing. Service connection effluent may be plugged only

after proper notification to the affected residence and may not remain plugged

overnight. Test and seal work shall not begin until the Vendor has installed a sewage by-

pass system and all pumping facilities have been installed and tested under full

operating conditions including the bypass of mainline and side sewer flows. The Vendor

shall coordinate sewer bypass and flow interruptions with the Owner, property owners

and businesses per Section 01 35 14 – Notification Procedures. The pump and bypass

lines shall be of adequate capacity and size to handle peak flows. The Contractor shall

this request for proposal and the manufacturer. All work performed is subject to review

and inspection by the County or their representative.

H. The Vendor shall be prepared to perform the requested services outside of public rights

to the Vendor, with little or no clearing required by the Vendor. Where clearing is

necessary the County will make arrangements for clearing and restoration by other

means.

I. No performance bonds are required.

J. All appropriate Federal, State and Local rules, regulations, and requirements must be

adhered to for this type of work.

K. Time is an essential element of the contract, and it is essential that the work be

vigorously prosecuted until completion, as the cost to the County of the administration

of the contract, including engineering, inspection, and supervision, will increase as the

time required for the work is increased. The discreet scope of services that shall be

requested under this bid will be assigned a time limit to complete the scope. At the time

the Vendor responds to a request for services, the Vendor shall consider the time limit

and make a recommendation for different time limit if the Vendor determines that the

one requested is insufficient to perform the work. For each day that assigned tasks

damages in amounts estimated by the County as necessary to recover expenses shall be

deducted from any payments due the Vendor.

L. Upon issuance of a purchase order for services, the Vendor shall begin work on the date

agreed to by New Castle County via schedule submittal and pursue completion of

specified tasks continuously on all acceptable working days until the services are

completed.

a. A working day is defined as a day upon which, in the opinion of the County or its’

more than half of his current normal force for more than five (5) consecutive

hours. Working days shall not include Saturdays, Sundays, and County

recognized holidays unless specifically approved by the County.

b. Working hours shall be confined to 7:00 AM to 4:30 PM unless specifically

approved, in advance, by the County on a location-by-location basis. These

working hours do not supersede time limitations that may be established by

DelDOT in a utility construction or traffic safety permit.

M. If night, Sunday or holiday working are deemed necessary, a request shall be submitted

to the Engineer at least three weeks in advance of the desired dates. If the task requires

access to sewer assets in the public right-of-way, then DelDOT must grant access by an

approved traffic safety permit, the County shall make application for the permit if the

Engineer is agreeable to the request. The County shall provide an inspector to be

present on behalf of the Engineer and will require the Vendor to reimburse the county

for inspection costs.

N. It is the County’s intent to aggregate sufficient work such that the value of each

purchase order is no less than $10,000. Should an occasion arise whereby the County

desires to issue a purchase order for quantities of work resulting in less than $10,000

using the bid prices, the Vendor reserves the right to request an adjustment to the unit

prices bid for County consideration.
