Award will be made as a whole to one bidder.

NOTE 1: Any bid may be rejected if the Contracting Officer determines in writing that it is unreasonable as to price. Unreasonableness of price includes not only total price of bid, but the price for individual line items as well. Any bid may be rejected if the prices for any line items or sub line items are materially unbalanced (See FAR 14.404-2).

NOTE 2: THE NOTICE TO PROCEED (NTP): The successful bidder is advised that performance and payment bonds shall be submitted in accordance with the time frame in block 12B of SF 1442. The NTP will be issued immediately after verification of acceptable performance and payment bonds. Within seven (7) days after issuance of the NTP, the Contractor shall initiate a meeting to discuss the submittal process with the Area or Resident Engineer or his authorized representative.

The Contracting Officer may exercise the OPTIONAL WORK Items by written notice to the Contractor. Bidders shall bid on all items including optional items (see “Evaluation of Options” FAR 52.217-5). Failure to bid on all items will result in non-responsive bid.

NOTE 4: EVALUATION OF OPTIONS (FAR 52.217-5 JUL 1990). Except when it is determined in accordance with FAR 17.206(b) not to be in the Government’s best interests, the Government will evaluate offers for award purposes by adding the total price for all options to the total price for the basic requirement. Evaluation of options will not obligate the Government to exercise the option(s).

**If an option is to be exercised at the time of the contract award in accordance with FAR 17.208, FAR clause 52.217-4 shall be used in place of FAR clause 52.217-5.

NOTE 5: TIME ADJUSTEMENT IN THE EVENT OF THE EXERCISE OF

OPTIONAL

WORK. In the event that OPTION WORK (Items 004 through 006) are exercised under the terms of the contract, an additional 305 calendar days will be added to the contract time. The Government will decide whether or not to exercise the option items within 300 calendar days after notice to proceed.

QUESTIONS AND ANSWERS

Questions: In the Solicitation Section B Bid Form indicates supply of 2 gates for base bid, and 2 gates for the option bid.

Please confirm if the 4 gates on the bid form (2 Base and 2 Option) are the 4 gates identified on Drawing G-005. Drawing G-003 and the Section C-1 Article 3.8.1 define a “gate” as 2 leaves, which is confusing.

Response: The base work and the option work each include the fabrication and delivery of 1 sector gate (2 sector gate leaves). The four gate leaves on the bid form (2 base and 2 option) are the four gate leaves identified on Drawing G-005. As described in Section C1, Paragraph 3.8.1, payment for fabricating the new gates will be made per each gate leaf.

The north gate (east leaf and west leaf) is included in the base contract and the south gate (east leaf and west leaf) is included in the option work.

Questions: Drawing G-003 Structural General Notes 4.6 indicates the offloading slings to be used shall be provided to the Contracting Officer.

Please confirm that one set of slings will be provided for the Base bid, and one set of slings provided for the Option bid.

Response: Confirmed. One set of slings should be provided with the base work and one set of slings should be provided with the option work.

Question: Can you please clarify who is responsible for the Field Milled Plate machining as noted on drawing M-501 (Rack Bracket Details)? Is the fabrication supplier responsible or the installation contractor “which I believe is a separate contract”.

Response: The contractor that installs the gate (separate contract from gate fabrication) is responsible for milling the steel band. This will be clarified in a forthcoming amendment.

Question: As I understand the scope of delivery: manufacture and deliver the 4 gates to the installations address. Anodes, wiring and installation to be done by others. Is this correct?

Response: The base work consists of fabricating and delivering one sector gate (two leaves).

The option work consists of fabricating and delivering one sector gate (two leaves). The contractor is responsible for purchasing and installing the support assemblies for the cathodic protection system. As stated on Sht. CP101, the anodes, reference cells, cables and conduits will be purchased and installed by others. Gate installation will also be by others.

Question: We plan on manufacturing in Houston and delivering by barge. There’s two options for delivering.

1. We deliver prior to installation and I’ll include a crane for unloading.

2. We keep the gates in stock in Houston until actual installation and the installation crane pick up from the barge.

Which one would be preferable?

What would be the estimated date for installation?

Response: Option 1 is preferable. We do not have an estimated date for installation.

Question: Confirm the thickness of the 5/8" plate noted on Rack Bracket Detail.

Response: The 5/8” plate callout in the Rack Bracket Detail has been deleted. This will be clarified in a forthcoming amendment.

Question: Can you clarify if the holes in the Rack Plate are slotted or through holes on drawing M-501? The drawing states 11/16" slotted and 1" through hole for the same holes. Note details "Rack Bracket Details", "Section A", and "Rack Section Standard".

Response: The slotted holes should be 1 1/16” x 1 5/16”. This will be clarified in a forthcoming amendment.

Question: Can you clarify the thickness of the Rack plate on drawing M-501.? The drawing states 0.75” and 5/8”. Note details "Rack Bracket Details" and "Rack Section Standard"

Response: The rack plate is 0.75” thick. This will be clarified in a forthcoming amendment.

INSTRUCTION TO BIDDERS

INSTRUCTION TO BIDDERS

Due to the response for COVID-19, most federal employees have been mandated to telework, and currently only authorized personnel are allowed access to the District buildings throughout USACE.
