3.0 SUBSURFACE CONDITIONS
3.1 Local Geology
The site is situated on the outcrop of the Austin Chalk Formation of Cretaceous Age. The Austin is chalky limestone with interbedded marl. In full section the Austin is over 700 feet thick and dips to the southeast approximately 2 degrees. Locally the Austin may be divided into three parts. The upper part contains more limestone than marl. The middle is composed of weaker limestone with thick beds of marl and the lower part consists of massive limestone with thin shale partings.
Considerable faulting has occurred in the formation. The faults are no longer considered active.
Displacements are normally less than 5 feet, but can exceed 30 feet. The Austin is not water bearing; however, groundwater often is found in the fracture zones associated with faults.
3.2 Site Investigation
Subsurface conditions were explored by drilling thirty-four borings at the approximate locations indicated on Exhibit A-1 in Appendix A. Logs of borings are presented on Exhibits A-2 through A-43. A description of the field work is presented on Exhibit A-44.
Laboratory tests were performed to evaluate soil engineering characteristics. A brief description of the tests is presented on Exhibit B-1 in Appendix B.
Reliable ■ Responsive ■ Convenient ■ Innovative 3
3.3 Typical Profile
Conditions encountered at each boring location are indicated on the individual boring logs.
Stratification boundaries on the boring logs represent the approximate location of changes in soil types; in-situ, the transition between materials may be gradual. Details for each of the boring locations can be found on the boring logs in Appendix A of this report.
Based on the results of the borings, subsurface conditions on the project site can be generalized as follows:
Stratum Approximate Depth to
Bottom of Stratum Material Encountered
Consistency/ Classification
Pavementa 4 to 6 inches Concrete or asphalt pavement
N/A
Stratum 1b At the surface or beneath the pavements, extending to depths of about 1 to 12 feet.
Fill materials consisting of clays, silty clays, sands, gravelly sands, silty sands, clayey sands, and processed limestone.
Clays: stiff to hard; CH and CL
Sands: medium dense to dense; SW, SP, and SC
Stratum 2c
Beneath the fill materials, pavements, or at the surface, extending to depths of about 2 to 12 feet. Boring B-24 terminated in this stratum at a depth of about 5 feet.
Tan, brown, dark brown, gray, and dark gray clays.
Stiff to hard Fat clays (CH)
Stratum 3d
Beneath Stratum 2 or beneath the fill materials, extending to depths of about 2 to 14½ feet.
Borings B-23 through B-27, and B-37 through B-39 terminated in this stratum at depths of about 5 feet.
Tan and brown silty clays.
Stiff to hard
Lean clays (CL)
Stratum 4 Beneath Stratum 2 or Stratum 3, extending to depths of about 7 to 27 feet.
Tan limestone. Clay layers were occasionally encountered. A gray limestone layer was observed in Boring B-17.
Hard
Stratum 5
Beneath Stratum 4, extending to termination depths of about 25 to 50 feet in the remaining borings.
Gray limestone Hard
Note a: Pavement materials were encountered in Borings B-4, B-5, B-8 through B-18, B-23, B-29 through B-32, B-35, and B-36.
Note b: Fill materials were not encountered in Borings B-4, B-10, B-17, B-28, B-33, B-35, or B-36.
Note c: Fat clays were not encountered in Borings B-13, B-15, B-18, B-19, B-22, B-29, B-30, B-35, or B-36.
Note d: Silty clays were not encountered in Borings B-2, B-5, B-8 through B-12, B-16, B-18, B-20, or B-24.
Reliable ■ Responsive ■ Convenient ■ Innovative 4
3.4 Groundwater
The borings were advanced in the dry using auger drilling techniques, which allows short-term groundwater observations to be made while drilling. Groundwater was not observed either during drilling or following the completion of drilling in the borings during the subsurface investigation.
Groundwater conditions may be different at the time of construction. Seasonal seepage typically occurs above the tan limestone. Groundwater may also be present in fissures and fractures within the limestone. Conditions may change because of seasonal variations in rainfall and landscape irrigation.
4.0 RECOMMENDATIONS FOR DESIGN AND CONSTRUCTION
4.1 Geotechnical Considerations
Based on the conditions encountered in the borings and the expected column loads, straight drilled shafts bearing in the gray limestone are recommended to support the structures at this site.
The potential for vertical movement in slabs and flatwork on grade varies from on the order of 1 to 4 inches for dry subgrade conditions. Due to the presence of expansive soils on this site, movement and cracking in the building floor slabs should be anticipated if supported on the clays. Floor slabs can be supported on a prepared or modified subgrade to achieve an estimated slab movement of about ½ to 1 inch. If the building floor slab movement must be limited to less than ½ to 1 inch, a floor system structurally suspended above the subgrade is recommended.
Below grade construction is anticipated for the Mental Health building, LTSCI building, and the parking garage on the western side of the site. Additionally, a tunnel system is planned between existing and future buildings.
Asphaltic concrete pavement or portland cement concrete pavement can be used at this site. If asphaltic concrete is used, the subgrade should be stabilized with lime. These pavements are not equal in performance. The portland cement concrete pavement is expected to require less maintenance.
Geotechnical recommendations for building foundations, floor slab support, below grade construction, pavement, and earthwork are presented in the following report sections.
From: John_Morse@fws.gov To: brichards@conxsis.com Subject: Proposed Dallas VA Medical Center Expansion Ms. Richards, This email is in response to your two November 20, 2010, letters requesting a review of the proposed Dallas VA Medical Center expansion. It is our understanding that the projects would include the construction of a Long term Spinal Cord Injury facility and the Clinical Expansion of Mental Health facility within the existing footprint of the Dallas VA Medical Center.
A county by county listing of federally listed threatened and endangered species that occur within the Service’s Southwest Region is available online at http://www.fws.gov/southwest/es/EndangeredSpecies/lists/. You should use the county-by-county listing and other current species information to determine whether suitable habitat for a listed species is present at your project site. If suitable habitat is present, a qualified individual should conduct surveys to determine whether a listed species is present. After completing a habitat evaluation and/or any necessary surveys, you should evaluate the project for potential effects to listed species and make one of the following determinations:
1) No effect - the appropriate determination when a project, as proposed, is anticipated to have no effects to listed species or critical habitat. A “no effect” determination does not require section 7 consultation; however, the action agency should maintain a complete record of their evaluation, including the steps leading to the determination of affect, the qualified personnel conducting the evaluation, habitat conditions, site photographs, and any other related articles. "No effect" determinations also do not require written concurrence from the Service;
therefore, due to limited staff resources and other priority actions, the Arlington, Texas, Ecological Services Field Office generally does not provide concurrence with these determinations.
2) May affect, but is not likely to adversely affect – the appropriate determination when a proposed action’s anticipated effects are insignificant, discountable, or completely beneficial. Insignificant effects relate to the size of the impact and should never reach the scale where “take” of a listed species occurs. Discountable effects are those extremely unlikely to occur. Based on best judgment, a person would not be able to meaningfully measure, detect, or evaluate insignificant effects, or expect discountable effects to occur. This determination requires written concurrence from the Service. A biological evaluation or other supporting information justifying this determination should be submitted with a request for written concurrence.
3) May affect, is likely to adversely affect – the appropriate determination if any adverse effect to listed species or critical habitat may occur as a direct or indirect result of the proposed action, and the effect is not discountable or insignificant. This determination requires formal section 7 consultation.
Given the highly urbanized nature of the project area it is unlikely that suitable threatened and endangered species habitat is present. If you have any further questions or concerns please feel free to contact me directly.

1.0 INTRODUCTION
1.1 PROJECT OVERVIEW
The Department of Veterans Affairs (VA) Dallas Medical Center is an 84 acre campus located at 4500 South Lancaster Road, Dallas, Texas, 75216. Figures 1 and 2 show the location of the VA Dallas Medical Center.
Figure 1: VA Dallas Medical Center, Vicinity Map
Primary vehicular access to the VA Dallas Medical Center is through the main entrance off S. Lancaster Road at the intersection of Mentor Avenue. It is also accessible by light rail via the VA Medical Center Station on the Dallas Area Rapid Transit (DART) Light Rail system.
M:\DWG-13\1352-09.237\Design\Wastewater Study\Report\1352-09.237 VA Wastewater Study Report.docx 2
Figure 2: VA Dallas Medical Center, Enlarged Location Map
Over the next several years, the VA will be constructing facility improvements at the VA Dallas Medical Center associated with the Long Term Spinal Cord Injury (LT-SCI) building and the Clinical Expansion of Mental Health (CEMH) building projects. Warehouse, parking facilities, and renovations and upgrades to existing facilities will also be constructed in support of these two major projects.
Exhibit 3, located in Appendix A shows the proposed site plan for the ultimate facility improvements. With the addition of facilities to the site, it is necessary to evaluate the impacts of added wastewater loads to the existing on-site wastewater collection system. The VA has requested that a comprehensive analysis of the system be performed. The purpose of this study is to assess the capacity of the existing on-site wastewater collection system under anticipated future loading conditions and identify any required improvements.
M:\DWG-13\1352-09.237\Design\Wastewater Study\Report\1352-09.237 VA Wastewater Study Report.docx 3
1.2 SCOPE OF WORK
The scope of work of this wastewater collection system evaluation includes:
Temporary wastewater flow monitoring;
Verification of the physical attributes of the existing system (pipe size, slope, service connections, etc.), based on available record information;
Determination of existing and proposed wastewater loads;
Evaluation of existing system performance under present-day conditions and under project build-out flow conditions;
Identification of deficiencies in the existing system; and Recommendations for any required improvements.
1.2.1 Data Collection
In order to determine the existing wastewater flows, Pacheco Koch identified nine strategic locations in which to take continuous flow measurements. A third-party consultant (Pipeline Analysis, LLC) was utilized to perform temporary flow monitoring at these sites. Continuous flow monitoring took place from January 8 to January 14, 2012 at eight of these locations. Flow monitoring of the ninth location took place from January 23 to January 29, 2012. A report entitled “Temporary Wastewater Flow Monitoring Final Report” was generated by Pipeline Analysis, LLC, and is included in this report in Appendix C. The results of the flow monitoring are described in greater detail in Section 2.2 of this report.
A topographic survey of the entire site was performed by Pacheco Koch in 2009.
This survey data was utilized for the purposes of this evaluation. The survey provides data related to manhole locations and flow line elevations. The survey data was used to determine pipe slopes in the existing system, and, combined with available record drawing information, was used to establish the layout of the existing wastewater collection system.
1.2.2 System Evaluation and Recommendations
The system was evaluated at three separate phases of site development:
Existing Conditions - Wastewater loading from the existing site prior to any new construction.
Proposed Phase 1 Conditions – Net wastewater loading from remaining existing facilities, new facilities that have been constructed since the flow monitoring was performed, and facilities that are currently under construction.
Proposed Phase 2 Conditions - Wastewater loading under ultimate build-out of the planned projects.
The downstream public system was not evaluated as part of this study.
Individual trunk-line pipe segments were identified and flow conditions applied to each segment at every phase. Calculations were performed to determine system performance and identify any deficiencies. The detailed system evaluation is located in Sections 2 and 3 of this report.

4.0 SUMMARY AND RECOMMENDATIONS
The VA Dallas Medical Center’s on-site wastewater collection system currently operates at an acceptable level. However, the Phase I and Phase 2 improvements described in this report are anticipated to add wastewater demand that would tax portions of the system beyond the VA’s defined acceptability level. It should be re-iterated that the identification of portions of the system as in-adequate are based on the VA criteria that flow levels not exceed 75% of pipe diameter. While some pipelines are projected to violate this criteria, in no instance is it projected that flow in any existing wastewater collection main would exceed the line’s full-flow capacity. Tables 13 and 14 below summarize the identified deficiencies and recommended corrective action.

Tab R2-LTSCI Acoustical Report CD1 SUBMISSION Dept. of Veterans Affairs, Washington, D.C. 20402 24 FEB 2012
LONG TERM SPINAL CORD INJURY
Overview Acoustical consultants from DataCom Design Group performed preliminary acoustical analysis and reviewed together with the other design team members (i.e. Architects, MEP, and etc) on VHA’s acoustical requirements, industry standards, acoustically sensitive spaces and critical adjacencies for the Long Term Spinal Cord Injury and associated projects.
This report is to summarize DataCom’s analysis and recommendations based on meetings with the design team and review of previous and current design documents.
This report is divided into two sections: Architectural and Mechanical. In the Architectural section, acoustical recommendations on room partitions and interior finishes are provided to achieve the appropriate sound isolation and absorption within the subject spaces, based on the designated functionality and room layout / adjacency of those space. In the Mechanical section, mechanical design recommendations and/or design guidelines are provided to meet the target noise criteria.
A. Architectural
1. Acoustical Isolation
For spaces with loud noise sources or activities, sound isolation should be considered.
The Sound Transmission Class (STC) is a single-number rating of a material's or an assembly's ability to resist airborne sound transfer at the frequencies 125-4000 Hz. In general, a higher STC rating results in less noise transmitted through a partition.
Per VHA PROGRAM GUIDE PG-18-3, the enclosures of the following spaces, if located adjacent to occupied spaces, shall be designed to achieve a minimum STC rating of 45. Refer to PG18-3 for additional requirements and information.
A/C and other mechanical equipment rooms.
Manual arts therapy shops.
Multipurpose rooms.
Emergency generator rooms.
Kitchen & Dishwashing spaces.
Note that:
(1) For Electrical room, Mechanical Rooms and other utility spaces with relatively loud noise sources, concrete or CMU walls and two-layer drywall partition with independent stud and minimum 1” air space between the stud and CMU or concrete wall will be considered to further damp the noise. The floor and/or ceiling slab shall have a minimum mass of 100 lbs/sqft (roughly 8” thick concrete), if the space above or below are occupied.
(2) For Emergency Generator rooms located adjacent to occupied spaces vertically or horizontally, double-layer suspended (with spring hanger) gypsum ceiling and additional double-layer gypsum wall on independent studs with minimum of 1” air space shall be installed at the Generator room side, in addition to requirements noted in item No.2 above.
(3) Sound rated (minimum of STC50) doors or regular doors with sound seals shall be scheduled to protect the acoustical isolation performance of the partitions.
Other spaces, not listed above but have potential loud noise sources or need quiet environment, are also recommended for consideration of acoustical isolation upgrade as listed below:
Classrooms
Meeting/Conference Rooms
Training Rooms
On-Call Rooms
Quiet Rooms
Meditation Rooms
Exercise Room
Dining
