Include the following notice in each solicitation:

“The information collection requirements contained in this solicitation/contract, are either required by regulation or approved by the Office of Management and Budget pursuant to the Paperwork Reduction Act and assigned OMB Control No.3090-0163.”

(a)  When using Standard Form 33, Solicitation, Offer and Award, include the following cautionary notice:

“Notice to Bidders—Use Item 13 of the Standard Form 33, Solicitation, Offer and Award, to offer prompt payment discounts. The Prompt Payment clause of this solicitation sets forth payment terms. Do not insert any statement in Item 13 that requires payment sooner than the time stipulated in the Prompt Payment clause (See FAR 52.232-25, 52.232-26, or 52.232-27, as applicable). EXAMPLE: If you insert “NET 20” in Item 13, GSA will reject your bid as nonresponsive because the entry contradicts the 30 day payment terms specified in the Prompt Payment clause.”

(b)  When using other authorized forms (e.g., Standard Form 1447, Solicitation/Contract; Standard Form 1449, Solicitation/Contract/Order for Commercial Products and Commercial Services), include the notice in paragraph (a) of this section. Change the reference to the form number, form title, and item number accordingly.

Requirements for Invitations for bids. When using brand name or equal purchase descriptions, the provision at FAR 52.211-6 satisfies the requirement for descriptive literature.

“Aggregate award” means an arrangement whereby two or more separately priced line items are combined for award to that bidder whose bid will result in the lowest overall cost to the Government for the line items as a group. The individual price for each item does not have to be the lowest bid received. (See also the definition of a “line item” in FAR 2.101 .)

(a)  GSA usually solicits prices and reserves the right to make award for individual line items. In some cases it serves GSA’s best interest to combine two or more line items for an aggregate award. Such cases include when:

(1)  Users desire uniformity of design, style, and finish, (e.g.,suites of household furniture).

(2)  The articles will be assembled and used as a unit, and different manufacturers’ components may not be interchangeable.

(3)  Users have high demand for certain articles, but demand for related articles is insufficient to attract competitive bids (e.g..,various sizes of socket wrenches).

(4)  Awarding the low-demand articles in conjunction with the high-demand articles may encourage competition.

(5)  One location (delivery point) has a large requirement, and another location has a requirement too small to individually attract competitive bids.

(6)  Awarding and administering numerous small contracts for similar articles or services is impractical.

(b)  Before deciding to combine items for aggregate award, the contracting officer should consider the following factors:

(1)  The capability of bidders to furnish the types and quantities of supplies or services in the aggregate.

(2)  How grouping delivery points will affect bidders.

(3)  Which combinations will accurately project the lowest overall cost to the Government.

(c)  The contracting officer should not use an aggregate award if it will significantly restrict the number of eligible bidders.

The solicitation should clearly state the basis for evaluating bids for aggregate award, require bidders to submit a price on each item within the group or a percentage to be added or subtracted from a list price, and advise bidders that failure to submit prices as required within a group makes a bid ineligible for award for that group.

(a) Supplies and services. This subsection applies to acquisitions of supplies and services.

(b)  Effect on competition. Provide for full and open competition when grouping items for award. Grouping items for award may preclude a significant number of firms from bidding. This occurs if firms are unable to provide all the types or quantities of supplies or services, or make deliveries to the various delivery points included in the prospective aggregate group.

(c)  Grouping different articles. Include only related articles in an aggregate group. Related articles are those normally manufactured or produced by a majority of prospective bidders. Grouping unrelated articles often restricts competition unnecessarily.

(d)  Grouping geographic locations or delivery points. Consider the following guidelines before deciding to group different geographic locations or delivery points:

(1)  A delivery point may have sufficient requirements so that individual shipments involve economic production runs and carload or truckload quantities. In this case, list it as a separate line item.

(2)  The types of bidders (i.e.,small or large firms, manufacturers or distributors, etc.) who responded to previous solicitations can provide important information. For example, if previous bidders are distributors with franchises in certain territories, grouping different territories could tend to restrict competition.

(3)  Transportation costs can affect competition and pricing. They may constitute a significant portion of the total delivered cost. Obtain the advice and assistance of transportation specialists before grouping geographic locations or delivery points. Depending upon the supplies being acquired:

(i)  Grouping widespread geographic locations or delivery points may reduce competition or result in higher prices. It can cause the loss of “area pricing” advantages provided by a supplier with a single production point.

(ii)  Conversely, for many small commercial products(hand tools, locks), manufacturers may quote the same price for delivery anywhere in the U.S.

(iii)  Tariff boundaries can also affect how manufacturers price deliveries to different areas.

(a) Definite quantity contracts without options. For definite quantity contracts without options, the evaluated bid price is the total bid price, as adjusted for any price-related factors identified in the solicitation. This reflects the actual cost to the Government and will identify the most advantageous bid.

(b) Indefinite quantity contracts, requirements contracts, and options. Indefinite quantity and requirements contracts use estimated quantities. Options involve the probability of whether and when the options will be exercised. These situations may result in unbalanced bids (see FAR 15.404-1(g)), leading to inaccurate evaluation of the projected cost and award to other than the most advantageous bid. To avoid unbalanced bids, GSA has two preferred methods for evaluating bids for aggregate awards: weight factors and price list.

(1) Weight factors method. Assign a weight to each item in a group. The weight is based on the portion of quantities that item represents. To evaluate bids, multiply each unit price by its weight factor, then total the results.

(2) Price list method. Establish prices for bidders to use as a base for preparing their bids. Prepare a list that identifies a base price for each item in a group. Bidders bid a percentage factor to add to or subtract from the base price.

(a)  Use the weight factors method when there are reliable estimates for the quantities needed in an acquisition. Reliable estimates of quantities form the foundation for:

(1)  Accurate evaluation of the projected cost of each bid.

(2)  An appropriate determination of which bid is most advantageous to the Government for the aggregate group.

(b)  Assign a weight factor to each item in a group. Develop the weight factor by calculating the portion of the total quantity in a defined group that each item represents.

(c)  To evaluate bid prices, first multiply the price bid for each item (unit price X quantity) by its weight factor. Then, add the subtotals together to project the cost for the aggregate group.

(d)  Estimated quantities may be reduced to smaller numbers by a common denominator. This may help facilitate the computations involved in evaluating bids.

(e)  Consider all price-related factors identified in the solicitation. Award to the responsive and responsible bidder with the lowest evaluated overall cost to the Government for the aggregate group. This represents the most advantageous bid.

(a) General. The price list method helps avoid unbalanced bidding when making aggregate awards, but lack accurate estimates of anticipated quantities. This method establishes base prices for bidders to use in preparing their bids.

(b) Solicitation requirements. When using the price list method, in the solicitation:

(1)  Include the price list.

(2)  Include an estimate of requirements.

(3)  Require the bidder to express its price as “net” or as a percentage added to or subtracted from the list prices for each group. Require the bidder to quote only one percentage factor for each group. This means that the bidder provides one percentage factor that applies to every item in a group; not a separate percentage for each item. “Net” indicates the bidder chooses to submit the list prices as its bid.

(4)  Identify the percentage factor in (3) above as a price-related evaluation factor.

(c) Developing list prices. Price lists may be developed using one or more of the following sources:

(1)  Industry published prices.

(2)  Industry surveys.

(3)  Government cost estimates based on knowledge of the supplies or services and previous contract prices.

(d) First time use for an product or service. The first time the contracting officer uses list prices for a product or service, give prospective bidders an opportunity to review the proposed list. Also provide information on how GSA will use the list prices. This information may be provided in a draft solicitation.

(e) Balanced prices. Ensure that the list prices for the grouped items bear a reasonable and balanced relationship to one another. Prices may be used from previous awards made using the weight factors method to develop price lists. Review those prices first to ensure they did not result from unbalanced bidding.

(f) Evaluation and award. Consider all price-related factors identified in the solicitation. Award to the responsive and responsible bidder whose percentage factor produces the most favorable price to the Government. This represents the most advantageous bid.

(g) Example. The following illustrates a bidding schedule arrangement for a group of items for aggregate award under the price list method:

(h) Special considerations for contracts for store stock items. Show estimated quantities only if estimates of demand for each item within a group can be derived from Government records or verified contractor sales reports. Use only current estimates. If the Government’s needs cannot be estimated, the solicitation may include past orders. (See CG Decision, B-209037, 82-2 CPD para 323 (1982).)

(i) Special considerations for repair and alteration contracts. In the solicitation:

(1)  List the estimated quantities for work to be performed during both normal working hours and outside of normal working hours.

(2)  State the percent of work anticipated to be performed during normal working hours.

(3)  List the unit prices for work to be performed during both normal working hours and outside of normal working hours.

(4)  Define “normal” in terms of hours and days of the week.

(5)  Advise bidders of the previous year’s total expenditures or portions of that total attributable to the listed items.

(6)  If providing quantity estimates, state that the estimates are for information only and do not constitute guarantees or commitments to order items under the contract.

(7)  Solicit two percentage factors for the line item unit prices listed: one for the unit prices for work performed during normal working hours and the second for the unit prices for work performed outside of normal working hours.

(8)  When the solicitation further groups unit prices by trade or business category, multiple percentages may be required.

(9)  For the evaluated bid price, add together (i) and (ii):

(i)  The percentage of work performed during normal work hours multiplied by the total estimate adjusted by the bidder’s percentage factor for that portion of the work, plus

(ii)  The percentage of work performed during other than normal working hours multiplied by the total estimate adjusted by the bidder’s percentage factor for that portion of the work.

(10)  Consider other price-related factors identified in the solicitation. Make award to the responsible and responsive bidder submitting the lowest overall evaluated bid price for the aggregate group. This represents the most advantageous bid.

Delegation of authority by head of the agency. Under FAR 14.407-3(e), contracting directors (see 502.101) are authorized, without power of redelegation, to make:

(a) The determinations regarding corrections and withdrawals under FAR 14.407-3(a), (b), and (c); and

(b) The corollary determinations not to permit withdrawal or correction under FAR 14.407-3(d).

The contracting director and assigned counsel are required to review and approve the contracting officer’s determinations under FAR 14.407-4(b) and (c).
