C -- The primary purpose of this contract is to obtain the services of an A-E to perform the thermal stress/strain analysis of the construction blocks of Portugues Dam. The dam is a concrete arch dam being constructed in Ponce, Puerto Rico. Preliminary analyses were performed to determine the construction block size, lift heights, and pre- and post- cooling requirements. These parameters are to be verified following the procedure and utilizing the analysis programs described in the Corps of Engineers, Engineer Technical Letter (ETL), No. 1110-2-365, dated 31 August 1994. Of primary interest is an evaluation of the expected behavior of the concrete during the hydration process, and during the final cooling period and contraction joint grouting. A basic principal of ETL No. 1110-2-365 is that the actual conditions that will be experienced during construction are not known. Therefore, sensitivity analyses shall be performed so that the expected behavior can be bracketed. The goal is satisfactory performance under a range of expected variations in material properties and construction sequences. The government will work closely with the A/E in developing a plan for the analyses and in the interpretation and evaluation of the results. The schedule for completion of this work is being driven by the schedule for advertisement of the construction contract. Therefore, all evaluations associated with these analyses must be complete prior to 28 July 2000. Factors for Evaluation are: 1. SPECIALIZED EXPERIENCE AND TECHNICAL COMPETENCE: Firms must clearly demonstrate specialized experience and expertise in the analysis of mass concrete structures. The use of the Corps of Engineers mass concrete material model and cooling coil model will be required, therefore, the firm must have experience and expertise using the general purpose finite element program ABAQUS and must have a license for this program. Demonstrated experience using the mass concrete material model as well as the cooling coil model is required. 2. SIZE AND EXPERTISE OF STAFF: Firm must have, either in-house or through association with qualified subcontractors, U.S. registered professional engineers and all necessary supervisory and administrative personnel necessary for performing the required analyses. 3. CAPACITY TO ACCOMPLISH THE WORK IN THE REQUIRED TIME: The schedule for these analyses is tied to the advertisement for the construction contract of the dam. Therefore, it is imperative that the technical evaluations be complete by 28 July 2000. Firm must have the capacity to commence work within 10 days after receipt of notification to proceed and accomplish the analyses in accordance with the scheduled completion dates. 4. PAST PERFORMANCE: Firm must demonstrate its past performance in the accomplishment of similar work. Firm must list current contracts and related information including the name, address, and telephone number of references. Pertinent issues are ability to meet established schedules, ability to accomplish work within budgetary limitations, and quality of the delivered product. Past performance on contracts with Government agencies and private industry regarding quality and timeliness of work will be reviewed. Past DOD experience data available to the Government through the A-E Contract Administration System (ACASS) and information available from other sources, will be utilized for prior performance evaluation. THE FOLLOWING SECONDARY CRITERIA WILL BE USED AS TIEBREAKER: 5. VOLUME OF PAST DOD CONTRACTS AWARDED TO FIRM: Work previously awarded to the firm by DOD will be reviewed with the objective of effecting equitable distribution of contracts among equally qualified firms. THIS IS AN UNRESTRICTED ADVERTISEMENT. Magnitude of Construction is between $25,000 and $100,000. Firms meeting the requirements described in this announcement and wishing to be considered, must contact Kathie B. Duke at 904-232-3713 PRIOR TO 10 MAY 2000. SIC CODE is 8711, Size standard is $4 million. Contracting information for the Jacksonville District is now available at our web site: http://www.saj.usace.army.mil/.
