EVALUATION CRITERIA:

TECHNICAL PROPOSAL INSTRUCTIONS

General Proposals shall be submitted in two parts: a technical proposal and a price proposal. Each part shall be separate and complete in itself so that evaluation of one may be accomplished independently of the other. The price proposal shall be submitted with the solicitation forms.

Offerors are cautioned that sufficient and detailed information must be presented in their proposals to enable the Government to evaluate their proposals fully in accordance with the evaluation and award criteria contained herein. The Government is not obligated to ask for additional information and in the absence of appropriate information, the proposal will be rated deficient.

Price Proposal A completed schedule of items with pricing information completes this requirement.

Technical Proposal Offerors shall submit technical information for their firm and any proposed major subcontractors. Please submit your past performance with the technical information. Also, the offeror shall submit information that illustrates a technical understanding of the work to be performed.

1) Relevant Past Performance:

Relevant Past Performance shall be obtained from previous work with the Federal Government and utilized for evaluation on this contract. Please provide at least 3 past performances with references.

2) Technical Approach:

All offerors should show a high level of understanding of the work to be performed. This can be accomplished by submitting with the proposal the following information:

1. Description of how the work will be performed

2. Schedule (accomplishing work while meeting weather conditions)

3. Key Personnel

4. List of equipment to be used

3) Experience/Qualification:

The Offeror will be evaluated on the experience and qualifications of their company and personnel.

12363N26Q4161 Mark Twain NF Beaver Lake Dam Rehabilitation Page 8 of 100

Technical Evaluation Criteria Technical proposals will be evaluated and rated by a Technical Evaluation Panel. Proposals shall be prepared in accordance with the proposal preparation instructions. The Government intends to evaluate quotations using a comparative evaluation methodology. This means quotations will be compared against one another to determine which provides the best value to the Government, based on the evaluation factors outlined in this solicitation.

The Government may consider quotations that exceed minimum requirements and offer additional value or benefits, even if they are not the lowest priced.

1) Relevant Past Performance:

a) Relevant Past Performance shall be provided and utilized for evaluation on this contract.

2) Technical Approach:

b) Understanding of Proposed Work: Offeror demonstrates a technical understanding of the proposed work including but not limited to preliminary scheduling, equipment requirements, site conditions and location, project challenges, and material requirements.

3) Experience/Qualification:

Evaluates the company’s history, background, and ability to perform work of similar size, scope, and complexity. Specialized work and accomplishments relative to the scope of work.

4) Acceptability:

An offeror’s documented response to the solicitation will not be deemed acceptable, if not received by the specified closing date and time, and the submitted proposal not clearly demonstrate the offerors understanding the needed work. In such cases the offeror will be viewed as having “failed” this criterion and will not be considered for award.

5) Cost or Price:

Each acceptable offer will be evaluated for reasonableness of proposal price. This criterion will include consideration of cost information provided. It is the Government's intent to assess the unit prices to determine reasonableness and offeror's understanding of the work and ability to perform the contract. The importance of price may become greater as the differences between technical proposals decrease. Where technical proposals are determined to be substantially equal, price may control award.

(b) Award. A written notice of award or acceptance of an offer, mailed or otherwise furnished to the successful offeror within the time for acceptance specified in the offer, shall result in a binding contract without further action by either party. Before the offer’s specified expiration time, the Government may accept an offer (or part of an offer), whether or not there are negotiations after its receipt, unless a written notice of withdrawal is received before award.

157 - SOIL EROSION AND SEDIMENT CONTROL

DELETE SUBSECTION 157.03 AND REPLACE WITH THE FOLLOWING:

157.03 SOIL EROSION, SEDIMENT CONTROL, AND DEWATERING PLAN.

REVIEW CONSTRUCTION PLANS AND THEN DEVELOP A SOIL EROSION, SEDIMENT CONTROL AND

DEWATERING PLAN. THE FOLLOWING CONCEPT IS PROVIDED AS A GUIDE AND SHOULD NOT

SUPERSEDE THE CONTRACTOR PREFERRED MEANS AND METHODS OF CONSTRUCTION. THE

CONTRACTOR CAN PRESENT OTHER METHODS IN THE PLAN. THE PLAN MUST BE APPROVED BY THE COR 20-DAYS PRIOR TO LAND DISTURBANCE ACTIVITIES. MAJOR OPERATIONS CONSIDERED IN PLAN

THAT REQUIRE DETAILED EROSION AND SEDIMENT CONTROL SHALL INCLUDE LAKE DRAWDOWN,

EXCAVATION & EMBANKMENT FOR CONDUIT AND SPILLWAY INSTALLATION. THE PLAN SHALL INCLUDE

CONTROL EROSION AND SEDIMENT BMPS TO BE UTILIZED DURING ALL OPERATIONS OF LAND

DISTURBANCE NOT CONTAINED WITHIN THE INTERIOR BOUNDARY OF THE NORMAL POOL ELEVATION.

THE LAKE MAY BE DRAWDOWN BY MEANS OF SIPHON OR PUMP (1). IF A SIPHON IS UTILIZED IT WILL

REQUIRE 3-STAGES OF OPERATION. THE MAXIMUM SIPHON SIZE IS 12” IN DIAMETER. PEAK

DRAWDOWN FLOWRATES MUST DROP WATER SURFACE NO MORE THAN 2-FT PER DAY TO ENSURE

UPSTREAM DAM SLOPE STABILITY. DRAWDOWN OPERATIONS SHALL MINIMIZE SEDIMENT REMOVAL FROM THE LAKE. DISCHARGE WATER SHALL HAVE A TOTAL SETTLEABLE SOLIDS (TSS) LESS THAN OR EQUAL TO 2.5 ML/L/HR. TESTING OF SETTLEABLE SOLIDS SHALL OCCUR WHEN REQUESTED BY COR TO

VERIFY PERFORMANCE OF EROSION AND SEDIMENT CONTROL MEASURES.

(1) DRAWDOWN LEVEL IS VARIABLE BASED ON CONTRACTOR’S CONSTRUCTION MEANS.

UTILIZATION OF TEMPORARY COFFER DAMS OR SIMILAR MEANS TO REDUCE THE DRAWDOWN

LEVEL IS ACCEPTABLE. THE ESTIMATED BOTTOM OF BASIN IS 533’. MAINTAINING A 6’

MINIMUM WATER DEPTH IS DESIRABLE TO AVOID AQUATIC ORGANISM MORTALITY (2).

DISCHARGE POINT TO DOWNSTREAM CHANNEL MUST BE AT LEAST 10-FT DOWNSTREAM OF THE TOE

OF THE DAM. THIS DISCHARGE POINT WILL REQUIRE EROSION CONTROL. CONSIDER PROPERLY

DESIGNED SEDIMENT FILTER BAGS (FP-14 713.19 SEDIMENT FILTER BAGS) OR OTHER MEANS IF THE SIPHON/PUMP IS PICKING UP SEDIMENT. IF FILTER BAGS ARE USED, CONTRACTOR SHALL DISPOSE OF
