B-2 – NOTES

1. Payment for bond premiums in accordance with Clause 52.232-5, Payments under Fixed-Price Construction Contracts, shall not be in addition to the contract price. Include bond payments under 151.01 Mobilization. Payment will be made on actual work performed as described in FP-03 109.01 unless otherwise noted.

2. The Standard Specifications for Construction of Roads and Bridges on Federal Highway Project FP-03 edition has been used for this contract. Copies of this book are available at the USFS engineering office in Duluth, Ely or Grand Marais.

3. The low offeror and the items to be awarded shall, in conjunction with Section M – Evaluation Factors for Award, be determined as follows-

a. Prior to receiving offers, the Government will determine the amount of funds available for the project.

b. The low offeror shall be the Offeror that-

i. Is otherwise eligible for award; and

ii. Offers the lowest aggregate amount for the base bid items, plus or minus (in the order stated in the list of priorities in the bid schedule) those additive or deductive items that provide the most features within the funds determined available.

c. The Contracting Officer shall evaluate all offers on the basis of the same additive or deductive items.

i. If adding another item from the bid schedule list of priorities would make the award exceed the available funds for all offerors, the Contracting Officer will skip that item and go to the next item from the bid schedule of priorities; and

ii. Add that next item if an award may be made that includes that item and is within the available funds.

d. The Contracting Officer will use the list of priorities in the bid schedule only to determine the low offeror. After determining the low offeror, an award may be made on any combination of items if-

i. It is in the best interest of the Government;

ii. Funds are available at the time of award; and

iii. In accordance with the other factors listed in section M

Page 2 of 3 3-13-2015

e. Example. The amount available is $100,000. Offeror A's base offer and four additives (in the order stated in the list of priorities in the bid Schedule) are $85,000, $10,000, $8,000, $6,000, and $4,000. Offeror B's base offer and four additives are $80,000, $16,000, $9,000, $7,000, and $4,000. Offeror A is the low offeror. The aggregate amount of offeror A's bid for purposes of award would be $99,000, which includes a base offer plus the first and fourth additives. The second and third additives were skipped because each of them would cause the aggregate offer to exceed $100,000.

4. All other items not listed above with unique bid items shall be considered incidental to the contract. See Specification

109.05.

5. Provide type of wood preservative assumed for bid as identified below.
