U.S. Department of Veterans Affairs Royal C. Johnson Veterans Memorial Center Phase II – Sioux Falls Pharmacy Addition for USP 800 Compliance Building #5

Summary of Work:

The current pharmacy at the Sioux Valls VA Medical Center does not meet USP 800 standards and is inadequate in size and

storage for current and future needs. The VA is requiring USP 800 compliance by December 2019. After discussing multiple

options, we determined the best choice to accomplish the goal would be to add a pharmacy adjacent to Oncology and

Occupational Therapy. After completion, the addition will be able to accommodate all compounding needs while the current

pharmacy is remodeled to be compliant with USP 800 standards in a future project. When both pharmacies are USP 800

compliant, this new pharmacy will be solely used for the adjacent Oncology department.

This project was limited to 2,300 SF and the location of the new pharmacy requires moving the Occupational Therapy treatment

rooms and work stations. Care was taken to maintain the current amount of space and storage in Occupational Therapy. Staff in

this department would have liked to maintain their exterior view, but this was impossible due to the existing grade elevation. To

compensate for this loss of exterior view and in an effort to save money and reduce waste, we chose to reuse their existing

windows and added an additional one to provide exceptional amounts of natural daylight into the space.

To connect the pharmacy to Oncology, the Oncology break room needed to be partially relocated into this addition. This was the

best option to interfere as little as possible with the Oncology ward, which was just completed in the spring on 2018. Our

addition also interfered with some windows in Oncology. Many options were discussed and we chose to make them a feature.

Our main determinates here were again, not wanting to interfere with the Oncology infrastructure or operations and not

wanting our alterations to cost a lot of money.

Blast and physical security requirements played a large role early in the design process, but it was later determined that this

addition is designed as an extension of the existing building so we received permission to use the design standards of the

existing building. Designing and building for blast and physical security requirements would have elongated the length of the

project and made it extremely difficult to meet all USP 800 requirements by the due date set by the VA.

This project was an extension of fairly recent additions, so no accommodation for hazardous materials was necessary.

Key Challenges:

The successful timeline of this project required excavation and footings to be completed before harsh winter conditions set in,

which was only 3 months after design began. This project being completed as Design/Build was critical to its success. The project

also required phasing to keep Occupational Therapy and Oncology operational with as little down time as possible.

This project required the relocation and accommodation of multiple mechanical units and a steam line. Three mechanical units

were relocated to the roof of the facility. After the 30% design submission, the location of the steam line was determined. The

cost of relocating the steam line was prohibitive so the addition was modified to accommodate the line as it is.

Interior Narrative:

The project follows VA standards for material selection and placement as outlined in Sioux Falls VA Standards and Finishes, VA

Interior Design Manual - May 2018 and VA Room Finishes, Door & Hardware Schedule Program Guide, pg 18-14- April 2017 Rev.

5/2017. The colors, patterns and application were coordinated with the existing finishes in Oncology and Occupational Therapy

with assistance and approval from the Interior Designer at the Sioux Falls VA Medical Center.

Project: (VA#438-500), (SGA#181906), (EGA#SD181135) Sioux Falls VA – Pharmacy Addition

Re: Civil Narrative for 100% Submittal

Design Overview:

The Sioux Falls VA - Pharmacy Addition civil site plan, is being designed using the most current additions of the

Veterans Affairs, City of Sioux Falls, and state of South Dakota design manuals and specifications. A poured

concrete structural retaining wall was discussed and determined to be utilized to protect ground cover over the

existing steam line, and allow access to the emergency exit. The proposed grading was designed for minimal impact

to the surrounding surface and follow existing drainage patterns.

• Existing Conditions:

The following are all within the foot print of the proposed addition, existing sidewalk, existing area inlet,

existing 8-inch water line, post indicator valve (PIV) with 6-inch water service line, and MRI utility

structures. All of these shall be removed or relocated outside of the footprint of the addition. The

relocation of the MRI utility structures was determined by the mechanical engineer. The rest were

determined by the civil engineer.

• Layout Design:

The existing steam line was potholed, and field located. This caused the location and geometry of the floor

plan and retaining wall to be redesigned and revised after the 30% Design Submittal. The retaining wall

shall be a poured concrete wall designed by a structural engineer. The proposed sidewalk was designed in

accordance with the most current Americans with Disabilities Act (ADA) design standards.

• Grading and Erosion Control Design:

The proposed grading was designed to drain to the east and away from the existing and proposed buildings.

Where it would be captured by the existing storm sewer system. The second design constraint was to keep

sufficient cover over the steam pipe and other existing utilities.

The limits of grading and reseeding areas were initially set at the edge of the match line between the

proposed grading and the existing surface. Following the 60% Review comments these areas were

extended north to the edge of sidewalk. Expanding these areas covers any damage to existing grass that

may occur during construction. Silt fence is to be installed to the east of the project at the edge of grading.

• Utility Design:

The existing sanitary, water and drainage services within the Rehab and Oncology Additions are being

continued and will pick up the internal plumbing for the proposed addition. A new area inlet will be

installed to capture the runoff from the sidewalk between the retaining wall and the addition. This will be

connected to the existing 6-inch drainage pipe. The fire service 8-inch water line and PIV were relocated

north west of the addition and reconnected to the 6-inch service entering the building. This was done to

keep the water lines from running under the addition’s footing. After the 60% Design Submittal and upon

excavation an existing 8-inch city owned water line was located and presumed to run under the proposed

footing. It was determined to use bends and reroute the existing water line around the proposed footing if

needed.

VA Review Comments, and Responses:

• 30% Review:

1. No comments regarding civil plans.

• 60% Review:

1. Please detail the temporary egress path from the Oncology exit door once sidewalk is

demo’d.

▪ Keynote number eleven was added to sheet 5.CD101, along with a hatch of the

designated egress pathway that needs to be maintained during construction. GBG

2. Remove concrete cofferdam on area drain and make pipe continuous.

▪ Concrete cofferdam will be removed with the area inlet. The remaining pipe should be

continued by the plumbing plan to connect to any interior drains. No changes made to

civil plans. GBG

3. Show where the three MRI cooling units are moving to.

▪ The new location for the MRI units shall be determined in the field by the mechanical

engineer, and shown on mechanical plans. No changes made to civil plans. GBG

4. PIV needs power and data, please place on electrical plan.

▪ The electrical connection should be shown and designed by the electrical engineer. No

changes made to civil plans. GBG

5. May need to extend the seed/mulch/fertilize line to sidewalk (see dwg).

▪ Limits of grading and seed, mulch, fertilize area was expanded to match the sidewalk to

the north, see sheet 5.CG102. GBG

PROJECT MEMORANDUM

Date: December 21, 2018 To: Todd Stone – Stone Group Architects From: Aaron Hartwell Project: Sioux Falls VA – Pharmacy Addition Project #: 2018‐204 RE: Structural Narrative for 100% Submittal

STRUCTURAL NARRATIVE Design Overview The pharmacy addition, hereafter referred to as the Facility, is being structurally designed in accordance with the International Building Code (IBC) and applicable Dept. of Veterans Affairs design manuals. Specifically, the Facility remodel is being designed to meet the requirements of the IBC 2015, ASCE 7‐10 (Minimum Design Loads for Buildings and Other Structures), and the following Dept. of Veterans Affairs design manuals: Physical Security Design Manual Mission Critical Facilities, Jan 2015, Structural Design Manual, Feb. 2014 and the Seismic Design Requirements H‐18‐8, Oct. 2016. For the most part, all other national design codes and Veterans Affairs documents are referenced from these governing regulations. Structural System(s) Selection and Overview The addition to the existing facility is planned to be a steel framed bearing system with exterior non‐load bearing metal stud walls and conventional cast‐in‐place concrete spread foundations. Addition to the existing structure will be separated to act independently of applied loads:

Foundations: Based upon the existing construction, the foundations for the addition are planned to be cast‐in‐place concrete with elevations to match existing where they tie in. Foundations will be designed to the allowable bearing capacity of the soils that were indicated on the original construction documents and modified by construction documents of additions to the building in the area the planned addition is located.

Exterior Walls: Planned to be metal studs supporting brick veneer. Exterior walls will be non‐load bearing with slip connection at the top of wall

Interstitial Floors: Planned to be a concrete slab on metal deck supported by steel joists. Interior bearing stud walls to support joists.

Roofs: The roof framing for the addition is planned to be steel construction with metal roof deck. The steel framing will provide an economical solution to support gravity and lateral loading.

Analysis Method(s) The bulk of the design of the facility remodel is being performed using hand calculations and by model software such as Risa 3D when required. New structure to be framed independently of existing building. No analysis of existing framing will be done except where new addition casts a snowdrift load on the existing roof to verify vertical load carrying capacity only. Design Loads The facility will be designed for the Dead Load (self weight) of the structure and the following superimposed loads:

Occupancy Category: The facility is regarded as an Essential Facility having a Type IV Occupancy in accordance with IBC 2015, ASCE 7‐10, and the VA Structural Design Manual due to the building being a hospital with surgery functions.

Live Load: In accordance with IBC 2015, ASCE 7‐10 and the VA Structural Design Manual as follows:

1. Typical Floor ...................................................................... 80 psf + 20 psf Partition 2. Lobbies & Main Corridors ................................................. 100 psf 3. Storage (Light) ................................................................... 150 psf 4. Mechanical Rooms ............................................................ 150 psf

Snow Load: In accordance the with IBC 2015 and ASCE 7‐10 and local codes, use the following: 1. Minimum Roof Snow ........................................................ 36 psf (includes importance) 2. Ground Snow .................................................................... 40 psf 3. Importance Factor ............................................................ 1.2

Other: Special case loadings are designed to be supported based on their actual weight and configurations. In addition, floors shall be designed to accommodate a 2000 Lb. load placed anywhere on the floor in a 2.5 square area based on the VA Structural Design Manual.

Foundations The new addition will be founded on conventional spread footings designed to meet the allowable soil bearing criteria that was used in original building design and modified by construction documents of existing additions to the building in the area the planned addition is located. Footing elevations will be stepped as required to match existing foundations and to step with changes in grade around the addition Subgrade preparation for the footings and floor slabs shall be in accordance with available soils investigations from previous addition projects to the hospital.

VA Sioux Falls – Pharmacy Addition

Mechanical/Electrical CD Narrative

December 12, 2018

A. HVAC

a. Two new rooftop units will be provided for this project, with one unit being variable air

volume (RTU-2) and one unit being constant volume (RTU-1). Separate units will be

provided to allow the new OT area to operate independently of the Pharmacy area.

Each area will be on different occupancy scheduling, while the Pharmacy area requires

precise pressure control and the OT area does not. In addition, RTU-1 serving the

Pharmacy will be required to be on backup emergency power, while RTU-2 serving the

OT area will not be. For this project, we will look at two strategies for the equipment.

The preferred Option #1 would be to utilize existing campus chilled water and heating

water, along with campus steam for humidification. Option #2 will still utilize campus

heating water and steam for humidification, but will utilize packaged DX cooling at the

equipment, in lieu of chilled water, should it be determined the campus chilled water

system cannot handle the additional capacity of the project. The loads for each system

are indicated in the narrative, and shortly after issue of this report, we will discuss the

capacity requirements with the VA and determine the best course of action for the

cooling system.

1. Final Design: In lieu of providing a variable volume RTU-2 for the OT portion of

the project, it was determined that the existing indoor air handing unit AHU-2

serving the existing OT space had enough spare capacity to serve the new OT

space. The existing AHU-2 is variable air volume and served with campus

chilled and heating water. For the new RTU-43 serving the pharmacy area, we

utilized option #1 which will use campus chilled water for campus, campus

heating water for heating, and campus steam for humidification.

b. (Option #1) RTU-1: 4,525 cfm supply air at 2.0” ESP with VFD; chilled water coil with

88.7F DB / 70.1F WB EAT, target 55F LAT off cooling coil (approximately 19 tons);

heating water preheat coil with 5F EAT, target 60F LAT off heating coil; 1,270 cfm

exhaust fan with VFD; insulated roof curb; Merv 8 pre-filter bank; Merv 14 final filter

bank; modulating outside air damper; modulating return air damper. Provide with

airflow measuring station on outside air opening and inlet airflow measuring station on

the exhaust fan.

1. Final Design: RTU-43: 3,950 cfm supply air at 4.0” ESP with VFD; chilled water

coil with 88.3F DB / 73.7F WB EAT, 23.6 tons; heating water preheat coil with -

5F EAT, 60F LAT off heating coil; insulated roof curb; Merv 8 pre-filter bank;

modulating outside air damper; modulating return air damper. Provide with

airflow measuring station on outside air opening and inlet airflow measuring

station on the exhaust fan. A desiccant dehumidification wheel was added to

the RTU in order to achieve the space temperature and humidity requirements

in the compounding rooms (68F and 50%). Finally, since the compounding

rooms are served with HEPA filters for each space, the MERV 14 filters were

removed from the RTU and only MERV 8 filters provided.

c. (Option #2) RTU-1: 4,525 cfm supply air at 2.0” ESP with VFD; chilled water coil with

88.7F DB / 70.1F WB EAT, target 55F LAT off cooling coil (approximately 19 tons), 95F

ambient; provide variable capacity scroll compressors on all circuits, heating water

preheat coil with 5F EAT, target 60F LAT off heating coil; 1,270 cfm exhaust fan with

VFD; insulated roof curb; Merv 8 pre-filter bank; Merv 14 final filter bank; modulating

outside air damper; modulating return air damper. Provide with airflow measuring

station on outside air opening and inlet airflow measuring station on the exhaust fan.
