BASIS OF AWARD AND EVALUATION FACTORS FOR AWARD
1.0 BASIS OF AWARD
Award of this Contract will be made to the technically acceptable responsible Offeror submitting the lowest priced offer – Lowest Priced Technically Acceptable Offer (LPTA). This acquisition will result in the award of a firm-fixed price, construction contract.
The technical evaluation of each proposal will be solely on the basis of Technical Evaluation Factors found in this section. The Government will evaluate each proposal on a technically acceptable/unacceptable basis only with respect to the technical evaluation factors (criteria) described herein. Award will be to the Offeror who presents the technically acceptable proposal with the overall total lowest price. It is the intent of the Government to award off initial offers without discussions.
2.0 PROPOSAL EVALUATION
2.1 Technical Evaluation:
Technical acceptability of your proposal will be based on all Factors receiving an acceptable rating by the Government (Please see the evaluation method of each Factor below of how “acceptability” will be determined) and other requirements of the RFP. The proposal will be evaluated according to the criteria for each Non-Price Evaluation Factor of this section.
Proposals will receive either an acceptable or an unacceptable rating for each of the evaluation factors. Find the description of the Overall LPTA Technical Ratings in Table 1 which is taken from Appendix C of the DoD Source Selection Procedures.
Table 1: Overall LPTA Technical Acceptable/Unacceptable Ratings:
Rating: Description:
Acceptable Proposal meets the requirements of the solicitation.
Unacceptable Proposal does not meet the requirements of the solicitation.
3.0 EVALUATION PROCESS:
The evaluation process consists of three parts:
1. Proposal Compliance Review. This is an initial review to ensure all required forms and certifications are complete, and a complete proposal is received. The initial review of each of the proposals will be conducted to check for apparent errors, omissions and areas which require clarification. The purpose of this preliminary review session is to eliminate minor irregularities or apparent clerical mistakes. This preliminary evaluation will ensure each proposal contains the Volume I (Technical) and Volume II (Price) separately and the correct number of copies.
2. Relevant Experience and Past Performance. Relevant Experience and Past Performance will be evaluated according to the CRITERIA for Non-Price Evaluation Factors found within this section.
3. Price Evaluation. The Government will evaluate price for fairness and reasonableness through the use of price analysis. Price will also be verified for unbalancing of line items.

ADJECTIVE RATINGS AND DEFINITIONS TO BE USED TO BEST REFLECT YOUR EVALUATION OF THE
CONTRACTOR’S PERFORMANCE
RATING DEFINITION NOTE
(E) Exceptional
Performance meets contractual requirements and exceeds many to the Government/Owner’s benefit. The contractual performance of the element or sub-element being assessed was accomplished with few minor problems for which corrective actions taken by the Contractor was highly effective.
An Exceptional rating is appropriate when the Contractor successfully performed multiple significant events that were of benefit to the Government/Owner. A singular benefit, however, could be of such magnitude that it alone constitutes an Exceptional rating. Also, there should have been NO significant weaknesses identified.
(VG) Very Good
Performance meets contractual requirements and exceeds some to the Government’s/Owner’s benefit. The contractual performance of the element or sub-element being assessed was accomplished with some minor problems for which corrective actions taken by the Contractor were effective.
A Very Good rating is appropriate when the Contractor successfully performed a significant event that was a benefit to the Government/Owner. There should have been no significant weaknesses identified.
(S) Satisfactory
Performance meets minimum contractual requirements. The contractual performance of the element or sub-element contains some minor problems for which corrective actions taken by the Contractor appear or were satisfactory.
A Satisfactory rating is appropriate when there were only minor problems, or major problems that the Contractor recovered from without impact to the contract. There should have been NO significant weaknesses identified. Per DOD policy, a fundamental principle of assigning ratings is that Contractors will not be assessed a rating lower than Satisfactory solely for not performing beyond the requirements of the contract.
(M) Marginal Performance does not meet some contractual requirements. The contractual performance of the element or sub-element being assessed reflects a serious problem for which the Contractor has not yet identified corrective actions. The Contractor's proposed actions appear only marginally effective or were not fully implemented.
A Marginal is appropriate when a significant event occurred that the Contractor had trouble overcoming which impacted the Government/Owner.
(U) Unsatisfactory
Performance does not meet most contractual requirements and recovery is not likely in a timely manner. The contractual performance of the element or sub-element contains serious problem(s) for which the Contractor's corrective actions appear or were ineffective.
An Unsatisfactory rating is appropriate when multiple significant events occurred that the Contractor had trouble overcoming and which impacted the Government/Owner. A singular problem, however, could be of such serious magnitude that it alone constitutes an unsatisfactory rating.
(N) Not Applicable
No information or did not apply to your contract
Rating will be neither positive nor negative.

1.2 DEFINITIONS
1.2.1 Satisfactory Materials
Satisfactory materials comprise any materials classified by ASTM D2487 as GW, GP, GM, GP-GM, GW-GM, GC, GP-GC, GM-GC, SW, SP. Satisfactory materials for grading comprise stones less than 8 inches, except for fill
SECTION 31 00 00 Page 5 material for pavements which comprise stones less than 3 inches in any dimension.
1.2.2 Unsatisfactory Materials
Materials which do not comply with the requirements for satisfactory materials are unsatisfactory. Unsatisfactory materials also include man-made fills; trash; refuse; backfills from previous construction; and material classified as satisfactory which contains root and other organic matter or frozen material. Notify the Contracting Officer when encountering any contaminated materials.
1.2.3 Cohesionless and Cohesive Materials
Cohesionless materials include materials classified in ASTM D2487 as GW, GP, SW, and SP. Cohesive materials include materials classified as GC, SC, ML, CL, MH, and CH. Materials classified as GM and SM will be identified as cohesionless only when the fines are non-plastic. Perform testing, required for classifying materials, in accordance with ASTM D4318, ASTM C136/C136M, ASTM D422, and ASTM D1140.
1.2.4 Imported Structural Fill
Well-graded mixture of sand and gravel, free of organics and construction debris or other deleterious material. Imported structural fill material shall contain no more than 20 percent fines (material passing the No. 200 mesh sieve, based on the minus 3/4-inch fraction), the fines shall be non-plastic, and the moisture content of the soil shall be within two percent of its optimum. All imported structural fill shall have a maximum particle size of three inches.
During wet weather or in wet conditions where control of soil moisture is difficult, structural fill material shall consist of clean, granular soil, of which not more than five percent by dry weight passes the No. 200 mesh sieve based on wet sieving the fraction passing the 3/4-inch sieve. The fines should be non-plastic. Steilacoom Gravel is suitable for use as structural fill during wet weather, provided all organic material is removed prior to use.
1.2.5 Degree of Compaction
Degree of compaction required, except as noted in the second sentence, is expressed as a percentage of the maximum density obtained by the test procedure presented in ASTM D1557 abbreviated as a percent of laboratory maximum density. Since ASTM D1557 applies only to soils that have 30 percent or less by weight of their particles retained on the 3/4 inch sieve, express the degree of compaction for material having more than 30 percent by weight of their particles retained on the 3/4 inch sieve as a percentage of the maximum density in accordance with AASHTO T 180 and corrected with AASHTO T 224 . To maintain the same percentage of coarse material, use the "remove and replace" procedure as described in Note 8 of Paragraph 7.2 in AASHTO T 180 .
1.2.6 Topsoil
Material suitable for topsoils obtained from offsite areas is defined as:
Natural, friable soil representative of productive, well-drained soils in the area, free of subsoil, stumps, rocks larger than one inch diameter, brush, weeds, toxic substances, and other material detrimental to plant
SECTION 31 00 00 Page 6 growth. Amend topsoil pH range to obtain a pH of 5.5 to 7.
1.2.7 Hard/Unyielding Materials
Hard/Unyielding materials comprise weathered rock, dense consolidated deposits, or conglomerate materials which are not included in the definition of "rock" with stones greater than three inches in any dimension or as defined by the pipe manufacturer, whichever is smaller.
These materials usually require the use of heavy excavation equipment, ripper teeth, or jack hammers for removal.
1.2.8 Rock
Solid homogeneous interlocking crystalline material with firmly cemented, laminated, or foliated masses or conglomerate deposits, neither of which can be removed without systematic drilling and blasting, drilling and the use of expansion jacks or feather wedges, or the use of backhoe-mounted pneumatic hole punchers or rock breakers; also large boulders, buried masonry, or concrete other than pavement exceeding 1/2 cubic yard in volume. Removal of hard material will not be considered rock excavation because of intermittent drilling and blasting that is performed merely to increase production.
1.2.9 Unstable Material
Unstable materials are too wet to properly support the utility pipe, conduit, or appurtenant structure.
1.2.10 Select Granular Material
1.2.10.1 General Requirements
Select granular material consist of materials classified as GW, GP, SW, or SP by ASTM D2487 where indicated. The liquid limit of such material must not exceed 35 percent when tested in accordance with ASTM D4318. The plasticity index must not be greater than 12 percent when tested in accordance with ASTM D4318, and not more than 20 percent by weight may be finer than No. 200 sieve when tested in accordance with ASTM D1140.
Provide a minimum coefficient of permeability of 0.002 feet per minute when tested in accordance with ASTM D2434.
1.2.11 Initial Backfill Material
Initial backfill consists of select granular material or satisfactory materials free from rocks two inches or larger in any dimension or free from rocks of such size as recommended by the pipe manufacturer, whichever is smaller. When the pipe is coated or wrapped for corrosion protection, free the initial backfill material of stones larger than two inches in any dimension or as recommended by the pipe manufacturer, whichever is smaller.
1.2.12 Expansive Soils
Expansive soils are defined as soils that have a plasticity index equal to or greater than 30 when tested in accordance with ASTM D4318.
1.3 SYSTEM DESCRIPTION
Subsurface soil boring logs are appended to the "Special Contract Requirements". The subsoil investigation report and samples of materials
SECTION 31 00 00 Page 7 taken from subsurface investigations may be examined at JBLM - Department of Public Works. These data represent the best subsurface information available; however, variations may exist in the subsurface between boring locations.
1.3.1 Classification of Excavation
No consideration will be given to the nature of the materials, and all excavation will be designated as unclassified excavation.
1.3.2 Blasting
Blasting will not be permitted.
1.3.3 Dewatering Work Plan
Submit procedures for accomplishing dewatering work.
