Perform Differential Settlements Assessment Between Main & Administrative Buildings Scope of Work # 672-23-103

1. FOREWORD

1.1. This document contains information and minimal submission requirements for contract documents specified in the A/E contract for each submission in the production of VA Schematics for this study. It will give VA reviewers and the A/E a clear understanding of what is required at each stage of the study.

1.2. This document does not relieve the A/E firms of their professional responsibility to produce fully coordinated study documents.

2. GENERAL DESCRIPTION OF THE STUDY

2.1. The San Juan VAMC is in the need to perform a geotechnical soil study and assessment. The intent of the study is to identify the severity and possible causes of a settlement being observed between the Main Building (#1) and the Administrative Building (#40), as well as provide recommendations for corrective measures and procedures. On the first floor between buildings there is an unleveled concrete slab in front of the loading dock elevators and in other areas that VA doesn't know its causes.

3. The Geotechnical Soil Study and Assessment Between Main & Administrative Buildings will include but isn’t limited to:

3.1. The engineer who prepares and oversees the geotechnical soil study must be a professional geotechnical engineer licensed in the Commonwealth of Puerto Rico. A valid copy of such license will be required as part of the contract documents. The professional seal indicating such license shall appear on the soil study report and assessment documents. The engineer whose seal is shown on those documents will be known as the Engineer of Record.

3.2. The Geotechnical engineer must have a proved professional experience of at least ten (10) years in geotechnical engineering and soil studies and assessments.

3.3. The soil study must take several soil samples, as deemed necessary for the determination of soil properties, analysis, identification, and validation of the causes of settlements and any other soil problem that may compromise existing buildings or utilities.

3.4. The soil study shall identify at least 3 feasible alternatives to correct the deficiency, each with cost estimates, time of completion, impact to the environment and surroundings. Also, shall provide advantage and disadvantage between each alternative.

3.5. At completion of the soil study, the Engineer of Record must produce and submit a technical soil study report that must be signed and sealed as indicated on section 3.1.

3.6. The technical soil study report must include, but not limited to:

3.6.1 Description of the performed soil sampling, testing, analysis, and study processes,

3.6.2 Boring logs,

3.6.3 Identification and description of soil problems, its severity and causes,

3.6.4 Identification and descriptions of the feasible alternatives to correct the soil problems. These descriptions must include the recommended process to that needs to be implemented to successfully correct the identified problem.

The A/E firm shall perform an analysis of the access areas that could be impacted during the construction and provide rerouted paths as necessary.

4. SELECTED A/E REQUIREMENTS

4.1. Selected A/E firm shall visit the site before submitting his final proposal. Visits to the site shall be made by appointment with the Contracting Officer. A/E firm shall have comprehensive knowledge, experience, facilities, instruments, expertise, equipment, and personnel to develop all required documents for this study.

4.2. The A/E is required to perform all necessary inspection, survey and evaluation of the existing study site and related utilities, systems, and distribution systems.

4.3. Site survey work shall consist of existing drawing verification, comprehensive research, investigation, evaluation and study of the existing systems, equipment, structure, and utilities etc.

4.4. Contract documents shall meet or exceed the requirements of this document.

4.5. A/E shall conduct coordination meetings between A/E technical disciplines before submitting material for VA review and provide minutes of the meetings to VAMC.

4.6. VA will provide an architectural as built in DWG, FCD or DXF format as per A/E request but does not warrant the 100% accuracy of the same. The VA will provide any other drawings from their files required by the A/E but does not warrant the accuracy of the same.

4.7. The A/E will certify compliance with all national codes used by the VA, and Federal Requirements and Regulations. VA design standard, VA master specifications, design manuals, and/or other publications should be obtained by the A/E at the following Internet addresses:

4.7.1. http://www.vaww.va.gov/facmgt/ae/

4.7.2. http://www.vaww.va.gov/facmgt/standard/

4.8. A/E shall keep the Project Manager and Contracting Officer informed at all times of the status and progress of the study.

4.9. The A/E shall prepare written minutes of each meeting with the Government concerning contractual and study matters. Copies of the minutes shall be furnished to the Contracting Officer within two calendar days of meeting. The A/E shall prepare written records of phone conversations addressing mayor study issues and furnish a copy to the Contracting Officer within five calendar days of contract.

5. SUBMISSION POLICY

5.1. The A/E shall submit a draft study report at 90% of study completion for VA team evaluation and approval.

5.2. VA team will take 15 calendar days to review the 90% submission for approval.

5.3. Fifteen calendar days after 90% submission approval, the A/E shall submit the 100% completion study report.

6. PERIOD OF PERFORMANCE
