SCOPE OF WORK FOR A/E CONTRACTOR

FOR OFFICIAL USE ONLY

Project Title and No.: Water Infiltration Analysis Building 116 / 656-20-141 Last Revised Date: 03/31/2020

1. GENERAL DESCRIPTION

The objective of this project is to identify the water infiltration issues in Building 116 (B116) and design a solution to repair deficiencies. Currently, B116 has 12 known water leaks on its perimeter walls - water leaks into the unoccupied crawl space and the adjacent utility tunnel.

Ultimately, this study and design will be the basis for a succeeding scope of work for a construction contract to repair the leaking walls.

1. Review Government Documents A/E firm shall perform original design document reviews, evaluate the design concept (what’s the envelope designed to), determine the buildings service history, inspections, onsite field investigative testing and analysis. A/E firm shall specifically review all documents, photos and other government provided material related to the water proofing requirements/water infiltration issues.

2. Review Site A/E firm shall also investigate the existing stormwater management system (above and below ground) to determine if it is designed and sized properly to divert water away from the building.

3. Test Site Several test methods shall be employed to accurately report the data and support recommendations for corrective action. The following test methods shall be used to identify the water infiltrations:

• Visual Surveys – Inspection mirrors, fiber-optic borescopes, etc. as necessary.

• Spray Testing and Leak Tracing - Simulated Rain and Wind test – (50-year event.)

• Thermal Imaging Scans at Each location – Infiltration & Leak tracing

• Electronic Leak Testing – Pinhole Leak Detection

• RILEM Tube Testing

• Destructive testing: In two locations, remove brick and associated envelope components to verify proper installation, and return to existing condition after evaluation. Locations to be reviewed and approved by the COR.

A/E firm shall mark locations of leaks and path of water infiltration on plans and in the basement of B116 (mechanical room and unoccupied space only) on the foundation walls with black felt tipped marker, identifiable from 6’ away from surface.

4. Submit Reports of Findings A/E firm shall officially state and provide evidence supporting or denying whether a design error in the original design is responsible for the leaks. A/E firm shall officially state and provide evidence supporting or denying whether an installation and/or material defect error is responsible for the leaks.

Report:

Describe the conditions under which the evaluation was conducted.

Describe the observations and measurements made.

Express findings and conclusion.

Locations of Leaks:

Drawings indicating locations and quantities.

Root Cause Analysis:

Provide a root cause analysis as to what caused the leaks and including how to correct the leaks (scope of work and cost estimate). What caused leaks at each location.

5. Identify Repair Options for VA Selection Repair Solution

Corrective Action at each location to solve leaks.

Written Scope Work.

Design plans – Plan Page and details (elevations and sections).

Specification Sections as needed for corrective assemblies.

Excluded Services Destructive Testing.

6. Design VA Selected Repair Methods

Background:

The Rehabilitation Center, B116, broke ground in the spring of 2014 and was completed in the fall of 2016. Construction consisted of a 17,292sf reinforced concrete columns and beams building, and a 1,755sf pedestrian walkway to Building 51. Beginning in 2016 several leaks were observed.

Functional Description of The Building:

The building includes fully designed spaces for functions such as Speech Therapy, Adult Daily Living, Psychologist, Low Vision and other rehabilitation and clinical functions, as well as Occupational Therapy clinic and charting areas, Physical Therapy clinic and charting areas, and an outside walking area. A shell space on the east side of the facility will be infilled in 2019 to incorporate several of the aforementioned services.

Consultant Qualifications:

Five past projects of similar scope of work within the last five years.

12. PROPOSED SCHEDULE

The St. Cloud (STC) Veterans Affairs Health Care System (VAHCS) Projects Section prefers to hold design review meetings on Friday afternoons from 12:45 p.m. – 4:30 p.m. These meetings are scheduled at the VAHCS, 4801 Veterans Drive, Saint Cloud, MN 55603. The Projects Section will evaluate the feasibility of scheduling design review meetings for some projects on days/times other than Friday afternoons. The A/E firm and the Projects Section will agree on a milestone schedule for the subject project prior to the Kickoff Meeting.
