ADDENDUM NO. 1

8/23/2023

This document is an Amendment of the Plans and Specifications for the KCTCS - PARKING LOT AND SIDEWALK REPAIRS PROJECT and shall be a part of and included in the Contract. When the Addendum conflicts with the original Specifications and/or Drawings, this Addendum shall govern.

Questions Received: The following are answers addressing questions received from Bidders to date:

1. Project of this scope often evolve after contract date. This can be due to unforeseen conditions such as geotechnical issues, weather, design assumptions, etc. Therefore, most projects of this scope are contracted and paid as unit price contracts. The use of a unit price contract makes the scope flexible as the owner, engineer, and contractor agree to make changes throughout the length of the contract.

a. Will the owner consider bidding the project as a UNIT PRICE contract?

i. ANSWER: Not at this time.

b. Will the owner be prepared to negotiate and execute change orders, as needed, if the project is bid as LUMP SUM?

i. ANSWER: Yes, See answer to 2.

2. Page 105/160 references a UNIT PRICE SECTION and requires the contractor to submit unit prices as time of bid. Please provide this schedule.

a. ANSWER: Contractor will need to provide schedule and schedule of values upon bid award and that will suffice for change order purposes.

3. Substantial Completion is specified on page 104/160 as 180 days, additionally final completion is listed as 60 days. All work on the project is seasonal and weather dependent.

a. What is the target start date?

i. ANSWER: Target start Date is Fall 2023

b. Will a winter shut down be issued as necessary if work starts in 2023?

i. ANSWER: Yes, there is expected to be a pause in working time for winter weather. The project will need to be left accessible while on hold for weather. The contract time will be halted when asphalt plants close for the season. The contractor has the option to do concrete work while in shut down.

c. Can minor work continue through a winter shutdown if such work meets all temperature limitations?

i. ANSWER: Yes, as much work as possible.

4. Who will administer, inspect, oversee, and verify pay requests on this project?

a. ANSWER: BFW Engineering

5. Is there a detailed AutoCAD, survey, or layout file available?

a. Can this file be made available immediately for pre-bid use?

i. ANSWER: No

b. Can this file be made available prior to construction?

i. ANSWER: Yes

6. Is there a geotechnical report, boring, pavement core, subbase core, or subgrade investigation to determine pavement structure depth and strength of subgrade?

a. ANSWER: See attached Pavement Coring Letter.

7. Please provide a specification and detail for crack filling. This must include details on the epoxy material and method of application.

a. ANSWER: Please see the attached Specification 321218 Asphalt Seal Coating & Crack Sealing.

8. Please provide a specification for seal coat.

a. ANSWER: Please see the attached Specification 321218 Asphalt Seal

Coating & Crack Sealing.

9. Will crack fill be required for any areas getting milled and/or paved?

a. ANSWER: Where milling occurs, crack fill is not required. However, if any areas receive an overlay without milling, crack fill will be required prior to placing the asphalt overlay.

10. Are contractors required to be Kentucky Transportation Cabinet PREQUALIFIED to submit bid on this project?

a. ANSWER: No

11. Will a KYTC Certificate of Eligibility suffice as a bidder’s qualification?

a. ANSWER: No

a. ANSWER: No, it is located between road and sidewalk in the reduced lane width area.

13. Will an alternate parking stop made from recycled rubber be considered for use

vs. the 3,000 psi stop specified?

a. ANSWER: Curb stops to be replaced should match the material of the curb stops on the existing site.

14. For areas noted “I” and per detail 12, 140 of 160 state 4% soil stabilization is required. 6% is the norm in this area. What is the depth of the existing subbase that is to be stored and reused?

a. ANSWER: 4% stabilization is sufficient for low drive and parking areas, four inches is anticipated for subbase.

15. For areas noted “J” and per detail 5,

a. Is removal of existing aggregate subbase layer required?

i. ANSWER: As required to achieve elevations.

b. Is regrading of the existing aggregate subbase layer required?

i. ANSWER: Yes, as required to achieve grade.

RE: Pavement Coring Letter Report

KCTCS Parking Lot & Sidewalk Repairs – WKCTCS

BFW No: 23033

Dear Mr. Brown, Bacon Farmer Workman Engineering & Testing, Inc. (BFW), is pleased to present this summary of our pavement coring investigation at the West Kentucky Community & Technical College that was completed on March 23, 2023. The purpose of our investigation was to determine pavement thicknesses as part of an evaluation for potential pavement resurfacing and sidewalk repairs. Our investigation consisted of advancing pavement cores at thirty six (36) locations. Pavement cores were measured and photographed in the field. All cores consisted of hot mix asphalt (HMA) pavement. No concrete was encountered at the coring locations. Dense graded aggregate (DGA) was present beneath the asphalt at all 36 core locations. A map showing pavement core locations and individual core photographs are appended to this letter. Table 1 summarizes the core thicknesses measured at each location.
