The following have been modified:

INSTRUCTIONS TO BIDDERS

BID OPENING

The bid opening will be held at the U.S. Army Corps of Engineers, Room 125, 502 8th Street, Huntington, WV 25701. For date and time of bid opening, see Block 13 on Standard Form 1442. Upon arrival, attendees must check in with the security desk to have the guards contact Leah Morgan at ext. 5548 to submit your bid and be escorted to Room 125 for the bid opening.

PRICE BASIS

Bidders are advised that only bids submitted on a firm-fixed price basis will be considered, and that bids submitted on any other than firm-fixed price basis will be rejected.

Bid price alterations, i.e., crossed-out or white-out changes on the bid will not be accepted unless the change(s) is/are initialed.

BID QUANTITIES

Bids for less than specified quantities of each item in the Schedule will not be considered. Failure to submit a unit price for each item where required in the bid schedule will be considered as a material deviation from the requirements of the solicitation, and the bid will be rejected. (FAR 14.404-2)

ARITHMETIC DISCREPANCIES

(a) For the purpose of initial evaluation of bids, the following will be utilized in resolving arithmetic discrepancies found on the face of the bidding schedule as submitted by the bidders:

(1) Obviously misplaced decimal points will be corrected;

(2) In case of discrepancy between unit price and extended price, the unit price will govern;

(3) Apparent errors in extension of unit prices will be corrected;

(4) Apparent errors in addition of job and extended price will be corrected; and

(b) For the purpose of bid evaluation, the Government will proceed on the assumption that the bidder intends their bid to be evaluated on the basis of unit prices, extensions, and totals arrived at by resolution of arithmetic discrepancies as provided above and bid will be so reflected on the abstract of bids.

ADDITIONAL INSTRUCTIONS

I. BIDS MUST SET FORTH FULL, ACCURATE, AND COMPLETE INFORMATION AS REQUIRED BY

THIS INVITATION FOR BID (INCLUDING ATTACHMENTS). THE PENALTY FOR MAKING

FALSE STATEMENTS IN BIDS IS PRESCRIBED IN 18 U.S.C. 1001.

II. THE HUNTINGTON DISTRICT CORPS OF ENGINEERS DOES NOT ACCEPT BIDS BY

FACSIMILE TRANSMISSIONS AND/OR EMAIL.

III. NOTE THE AFFIRMATIVE ACTION REQUIREMENTS OF THE EQUAL EMPLOYMENT

OPPORTUNITY CLAUSE (FAR 52.222-23) WHICH WILL APPLY TO THE CONTRACT

RESULTING FROM THIS SOLICITATION.

IV. ONE SEALED PAPER ORIGINAL AND ONE PAPER COPY OF BIDS ARE DUE AT THE

PLACE SPECIFIED ON THE STANDARD FORM 1442, ITEM 8. IN ADDITION TO THE HARD

COPIES, IT IS PREFERRED THAT BIDDERS SUBMIT A SEARCHABLE PDF DOCUMENT ON

A CD OR DVD. SUBMISSIONS RECEIVED SOLELY VIA ELECTRONIC MEDIA SUCH AS

V. IF THE APPARENT LOW BIDDER IS OTHER THAN SMALL BUSINESS, A

SUBCONTRACTING PLAN MAY BE REQUIRED IN ACCORDANCE WITH FAR CLAUSE

52.219-9 ALTERNATE I (DEVIATION), SMALL BUSINESS SUBCONTRACTING PLAN.

VI. EFFECTIVE SEPTEMBER 26, 2018 AND IN ACCORDANCE WITH FAR CLAUSE 52.204-7, “AN

OFFEROR IS REQUIRED TO BE REGISTERED IN SAM WHEN SUBMITTING AN OFFER OR

QUOTATION, AND SHALL CONTINUE TO BE REGISTERED UNTIL TIME OF AWARD, DURING

PERFORMANCE, AND THROUGH FINAL PAYMENT OF ANY CONTRACT, BASIC AGREEMENT,

BASIC ORDERING AGREEMENT, OR BLANKET PURCHASING AGREEMENT RESULTING FROM

THIS SOLICITATION.” VENDORS ARE HIGHLY ENCOURAGED TO CHECK THEIR

REGISTRATION STATUS AND PLAN ACCORDINGLY PRIOR TO SUBMITTING A BID.

DETERMINATION OF RESPONSIBILITY

To ensure award is made to a responsible bidder, a determination of responsibility will be conducted. The apparent low bidder will be contacted by the Contracting Officer and will be required to provide the requested responsibility information within 4 calendar days. As part of this responsibility determination, the Contracting Officer will utilize the guidance contained in FAR 9.104-1. To be determined responsible, a prospective contractor must:

a. Have adequate financial resources to perform the contract or the ability to obtain them.

b. Be able to comply with the required or proposed delivery or performance schedule.

c. Have a satisfactory performance record.

d. Have a satisfactory record of integrity and business ethics.

e. Have the necessary organization, experience, accounting and operational controls, and technical skills, or the ability to obtain them.

f. Has the necessary production, construction, and technical equipment and facilities, or the ability to obtain them.

g. Be otherwise qualified and eligible to receive an award under applicable laws and regulations.

DEFINITIVE RESPONSIBILITY CRITERIA

In addition to examining the criteria in FAR 9.104-1, the Contracting Officer will also examine whether the apparent low bidder can meet the requirements of the following two definitive responsibility criteria. After bid opening, but prior to award, the apparent low bidder will be required to furnish documentation showing that the prime contractor or subcontractor(s) has/have completed:

a. No more than a total of eight (8) projects showing experience with placing at least a cumulative total of 75,000 cubic yards of mass concrete with 1.5 inch (or greater) aggregate and setting up and operating a batch plant in support of the project(s). Note that the quantity of concrete is the cumulative total of all submitted projects.

b. Two (2) projects showing experience directionally drilling through concrete and rock on a 1:150 tolerance as measured against a specified center line with real time survey and directional correction capabilities.

Firms may use prime or subcontractor (to be used on this project) experience to demonstrate experience with the definitive responsibility criteria, but the work performed by each entity on projects demonstrating that entity’s experience with the definitive responsibility criteria shall be the same as the work to be performed by that entity under this procurement. In order for experience to qualify under either of these criteria, the documentation must show that the experience was direct and not by-standing. By-standing means that the entity participated in a construction project but did not directly execute the features of work identified above. Personnel experience may be submitted as documentation to meet criterion (b) only. Should an entity intend to satisfy criterion (b) with personnel experience alone, the documentation must show that the entity is able to provide the necessary equipment to support the personnel in that role.

The apparent low bidder will have ten (10) calendar days after the Government’s request to submit the documentation demonstrating that it meets the above definitive responsibility criteria, and will receive award of the contract if otherwise eligible and responsible. If the apparent low bidder cannot provide this documentation, or if the documentation it submits does not show that it meets these criteria, the apparent next low bidder will be requested to provide this documentation. If this apparent next low bidder timely provides the documentation within ten (10) calendar days after the Government’s request, it will receive award of the contract if otherwise eligible and responsible. This process will be followed until the apparent low bidder who meets the requirement can document that it meets the definitive responsibility criteria or the Government cancels the solicitation.

SECTION 00 70 00 - CONDITIONS OF THE CONTRACT

The following have been modified:

52.236-4 PHYSICAL DATA (APR 1984)

Data and information furnished or referred to below is for the Contractor's information. The Government shall not be responsible for any interpretation of or conclusion drawn from the data or information by the Contractor.

(a) The indications of physical conditions on the drawings and in the specifications are the result of site investigations by surveys, core borings, etc., and previous construction at the site. Records consisting of drive sampling and core boring data gathered to determine the characteristics of the materials at the site have been compiled by the Government. Locations of borings and associated graphic logs are shown on the drawings.

Corresponding typed logs are included in Section 00 01 15 BORING LOGS.
