Please refer to item 1 of this addendum. - Payment for the service line replacements will be made at the Contract unit price per each for Contract Item 2, 3 and 4 respectively.

• Section 01-29-50-3 Bid Item 3 and 4 states replace mater valve before the water meter. Exhibit A service line standards states that the owner must install two valves at the meter, before and after. Please clarify if it is one or two valves and if the contractor is responsible for installation of the valves. Does this work need to be done by a licenses plumber?

Replacement of existing master valve (ball valve before meter) is to be completed. A licensed plumber must be on hand.

• Section 01-50-00-8 Field sheds B Location – coordinate with owner. Do you provide the contractor with a staging area for equipment and materials for this project?

Yes, WWW has an area for a lay down yard that was visited by all contactors on Oct 17, 2025. WWW is NOT responsible for any lost or stolen items there is no security but there is a bar gate that’s locked daily by the Public Works Dept. There are NO utilities/facilities at the lay-down yard.

• What permits or licenses (state, federal, local, plumbing, road opening) do you anticipate the contractor needing for this project and what are the costs associated with each?

Contractors will be responsible for any State of CT Department of Transportation application and permit fees. Call the state of CT for costs. Building & Water permit fees in the Town of Windham have been waived. Contractor is responsible for filling out the paper permit’s out per location for the water dept and the building dept.

• Exhibit A states no charge permit including the town bond. Are we required to purchase a bond for permits? Are all the permit fees waived?

WWW will issue no charge permits for the lead service line replacements. No Town of Windham bond will be required.

• Section 01 11 00-3 1.13 constraints states that no more than 5 properties can be under construction at the same time. The next page 1.6 work sequence mentions multiple crews. Can we have multiple crews working at the same time? If we have 2 crews working, more than five properties will be affected per day. Please clarify.

You can have multiple crews working at the same time. No more than five (5) properties may be under construction at one time during the Work. CONTRACTOR is responsible for performing all restoration necessary following the installation of a new service line before that property will not count as one of the five properties under construction.

• Please provide prevailing wage information for this project.

Feel free to do your own research on the State of CT Department of Labor.

• Can a bid unit be added for yearly price escalation? Possibly a percentage increase to be applied to each bid item per year?

Each year or phase has its own bidding form.

• Are all/most of the curb stops located in the sidewalks as shown in Exhibit A?

Most of the curb stops are located in the sidewalks or close to them.

• Are police details required for traffic control or are flaggers required? How is traffic control paid for on this project? Do you have a company that is used locally for traffic control?

Yes. In State roads they require state police for traffic control. In Town roads they require local police. The contractor is responsible for the payment of these details.

We don’t use companies for traffic control. Please see exhibit A for local and state roads.

• What is the completion date for this contract?

WWW is looking to have this job completed no later than 10/30/2030 5 years if not sooner.

• When does the curb stop get replaced? During full main to meter replacements and public side main to curb replacements or does it also get replaced when doing the private side curb to meter only?

Curb stops will be furnished and installed only as directed by the Owner per the contract document.

• Property list (service address, service ID, customer type).

See Appendix B.

• Service type per address (System-Side only, Building-Side only, or Full). (As defined in Contract Items—System-Side = main to curb stop; Building-Side = curb to building.)

See Appendix B

• Estimated lengths:

WWW doesn’t have these

• Curb stop locations (coords or sketches) and note if relocations are expected.

WWW can supply Tie Card Drawings by request.

• Surface/restoration breakdown per address (SY or SF by surface type: pavement, sidewalk, lawn/loam): this will align with the unit-price restoration items.

Windham Water Works does not have those estimates.

• Any constraints/notes per address (traffic control needs on specific streets, night work restrictions, access limitations, meter location quirks, multi-unit dwellings, etc.).

See Appendix B for traffic control needs by street. No night work is allowed.

• Electrical bonding/grounding scope triggers per address (e.g., panel bond needed, meter bond only) so we can coordinate with the Electrical Grounding Allowance.

All electrical must not be grounded to the water service line.

• As-built requirements format for service laterals (CSV fields, photo naming, coordinate accuracy) to match the documentation requirements.

• Yes
