Introduction
The University of South Carolina’s Thomas Cooper Library serves a fundamental role supporting campus life and learning. Not only does it provide academic resources, but it serves as a place where students, faculty, and visitors experience the spirit of the University’s mission. The library’s internal Spaces Planning Team states “Our goal for Thomas Cooper Library is to inspire discovery, collaboration, and scholarship.” In a digital age where most students or faculty can conduct research, study, or collaborate from anywhere, Thomas Cooper Library must seek to continually evolve to remain relevant in service of these goals. In addition to the academic aspirations of the library, security is an increasing concern, particularly in buildings such as the library that manage a significant traffic flow of students and visitors. Providing a welcoming, safe, and secure environment is paramount to the success of these goals and addressing the goals for success and improved security require a careful and through evaluation of existing conditions.
Scope of Study
The University of South Carolina contracted Quackenbush Architects + Planners to develop a redesign of the Main Floor of Thomas Cooper Library. This study provides a roadmap to revitalize the current library interiors with a focus on improving the layout and access to resources, updated interior finishes that reflect original historic design intent, and creating a welcoming and secure front entrance. The scope of this study included:
• Research of historical architectural design and evaluation of library case studies
• Evaluation of library departmental spatial needs for the Main Level and study of how service points function
• Documentation of current student seat counts and reference collections for the Main Level
• Documentation of current computing and printing services
• Code Analysis and summary of entrance and exit data to inform design of new secure entrance
• Evaluation of existing Mechanical, Electrical, and Plumbing systems regarding proposed renovation concepts
• Development of design concepts
• Probable Cost Estimate

Project Goals
The following goals were established by Thomas Cooper Library Spaces Planning Team regarding the front entrance on the Main Level:
The Spaces Planning Team recommends the renovation of the entrance and front area of the Main Level of the Thomas Cooper Library to more appropriately reflect its role as a place of learning and discovery for our University. By securing the front entrance, we will better serve our students and faculty and create a safer environment for all our visitors. For reasons of safety and security, utility, and aesthetics, we propose that the entrance be updated to:
• Facilitate secure sign-in. Visitors will register to enter, while students will swipe IDs (real or digital)
• Provide a welcoming and inspiring space where patrons can quickly get directional, basic technical, and basic reference (known item searching) assistance, and be referred to more in-depth services
• Create a clear navigational flow
• House an intuitive printing hub where students can quickly print and assemble their work
In addition to these goals, this study will provide a more ambitious plan to re-invent Thomas Cooper Library by integrating the goals for the transformation of the front entrance with a more comprehensive re-design of the entire Main Level to include:
• Streamlining the library user experience by improving access to research and instruction librarians
• Provide a variety of study and collaboration space better suited to current needs
• Increase the quantity and quality of student seating
• Update and integrate technology to reflect a more 21st century learning environment
• Create better sightlines for improved navigational flow and access to all existing means of vertical circulation throughout the Main Level
• Increase the access to natural daylight for all patrons and a return to the original historic design intent
• Update interior finishes with materials that reflect the original historic design while also meeting needs for durability and a timeless aesthetic
• Create an environment that will “showcase scholarship” with space for presentations, exhibits and digital displays

Thomas Cooper Library History
The Thomas Cooper Library is an icon of architectural destination on the University of South Carolina’s main campus. The original structure envisioned in 1959 by architect Edward Durell Stone and the local architectural firm, Lyles, Bissett, Carlisle & Wolff, was that of a “temple” dedicated to serving as the university’s Undergraduate Library.
In response to a need to consolidate the university’s collections, operations, and growing student population, a subsequent renovation of the original building in 1976 expanded the library’s capacity by more than twice the original design. In this process the interiors of the library shifted from iconic architectural design to a more utilitarian space focused on the operations and support of evolving technology.
Additional interior renovations over the past decade put even more emphasis on addressing emerging technology and resources. The addition of computers located on the Main Level at the front entrance were originally designed for short term use in searching catalogs and indexes but have evolved into a literal computer lab. Although most research assistance is given online or in scheduled consultations, the Research and Reference Help desk adjacent to the computer stations still serves as a resource for directional, technical, and printing inquires. The main circulation desk and library administrative operations are disconnected from Research and Reference Help, as well as from the small security and information desk located near the vestibule. This disconnect of service points has a negative impact on wayfinding for patrons and visitors.
New amenities, such as Starbucks and updated study spaces on lower levels, have helped make the library a destination; however, to remain relevant, the library must address the lack of security, outdated finishes and furnishings, and efficiency of service points.

Influential Work of Edward Durell Stone
To enrich our understanding of Edward Durell Stone and his legacy as a design influence for Thomas Cooper Library, Quackenbush Architects + Planners conducted research of his significant projects that include similar design strategies and other notable design elements of his style.
The exterior design of Thomas Cooper Library was influenced by many of Stone’s iconic elements that are found in his other works such as the Stuart Pharmaceutical Company, Pasadena, CA (1956), U.S. Embassy in New Delhi, India (1959), and the John F. Kennedy Center for the Performing Arts in Washington, DC (1962). The interiors are also reflective of some of these works. The original large and open multi-functional central space of the Main Level took full advantage of natural light and views. The original interior finishes were simple yet luxurious materials reflective of Mid-Century Modern design, yet unlike other works by Stone, lacked the intrinsic connection to the exterior character. Furnishings were in the Mid-Century Modern style and were scaled and positioned to encourage interaction. Patterns and color, another of Stone’s design influences, were found in the long curtains made of round gold-colored anodized aluminum discs and the 1976 addition of gold anodized aluminum honeycomb patterned screen on the exterior curtain wall.
The key elements of design influence that were a driving force behind the recommended concepts in this study include:
• Filtered daylight
• Clean, white and natural finish materials
• Open sight lines and one point perspective views
• Clear and focused organization

Thomas Cooper Library Main Level Renovation Study | 11Chapter 3: Program & Concept Diagrams
Process Overview
Programming data was gathered for the Circulation and Research and Instruction Departments that occupy existing space on the Main Level of Thomas Cooper Library. This data was evaluated to determine which staff and staff space had critical need to be located on the Main Level and what spaces could be consolidated and/or relocated on other levels of the library.
Student Study space both open and enclosed was documented by seat count. The existing layout includes seating for approximately 400-420 students in a variety of settings - group study, individual study, and computer/printing.
Starbucks location to remain.
Goals for programming of the re-design included:
• Establishing a logical and efficient division of space for circulation activities.
• Design of an appropriately sized and central check in/check out desk to include upgraded security equipment and staff
• Increased size of space available for classroom/presentation
• Reduced the number of book stacks and computer stations

The Speedlane Lifeline series is a design oriented range of optical turnstiles which manage and channel the flow of people entering and moving around buildings. The series consists of three models: the Open, Slide and Swing, each of which has a whole array of finish and function options.
Unique FeaturesThe form given to the Lifeline Series is sleek, ergonomic and refined. The ‘V’ shape of the product, seen from all angles, creates the impression of spaciousness and a
much smaller footprint. Combined with a mirror panel at its base, the product “floats” above the floor, giving a sense of futurism.
CustomizationWhether making a statement, fitting with corporate identity colors or creating a harmonious interior design, the Speedlane Lifeline Series can be customized to the latest design trends, offering the opportunity to blend-in or stand-out from its surrounds.

PLUMBING SYSTEMS
1. GENERAL
The plumbing system will cover all materials, fixtures and workmanship complete to provide all items as will be shown on the plumbing and architectural drawings. The plumbing system will be designed in accordance with the requirements of the 2018 International Plumbing Code, and all local and state codes. Plumbing systems shall be designed to meet the requirements of the American’s with Disabilities Act (ADA) and will be designed with water conservation in mind to reduce utility costs. All plumbing will be accomplished to connect to the fixtures as indicated on the current architectural drawings.
The general scope of this project is to replace all of the existing fixtures in the same location as the existing fixtures but to provide an aesthetic upgrade. Existing fixtures do not necessarily accommodate correct ADA heights, so the new fixtures may require some adjustments for correct heights. There is an existing hot water line exposed in the existing restroom that will be replaced. A new single occupant restroom is being added as required and a new janitor’s closet is being added.
The following narrative describes the systems more completely.
2. SUPPLY PIPING
All above grade piping will be type L copper piping with joints made with lead free solder. The Viega, or similar, “ProPress” system of piping will be allowed as an option. Where possible, the existing domestic cold water piping will be reused with some alterations made for new fixture heights in the current restrooms. For the cold water piping for the new individual restroom, the custodial closet, and the new hot water piping, it is anticipated that the piping will be run primarily above the ceiling of the floor below and fed up to the fixtures. This will allow access to the piping for repair or maintenance at future dates and will locate the supply piping above the same ceiling where the new waste piping will be routed. All domestic water piping will be insulated with 1” thick fiberglass insulation. There will be new shut off valves added for the new individual restroom as well.
3. WASTE PIPING
Waste lines will be standard weight hubless cast iron with heavy-duty clamps and will connect to the existing sanitary waste system. All waste systems will be served with above ceiling cleanouts located above the accessible ceiling on the floor below. Only the new fixtures are anticipated to have new waste piping as the waste piping for the removed fixtures is anticipated to be reused.
4. VENT PIPING
All new sanitary vent piping will be standard weight hubless cast iron with heavy-duty clamps. Minimum vent size will be 2” and will connect to the existing sanitary vent system. Only the new fixtures are anticipated to have new vent piping as the vent piping for the removed fixtures is anticipated to be reused.
5. DEMOLITION
All existing fixtures, carriers, etc. shall be removed and disposed of properly. Existing piping at the fixtures will be reused at the same location where possible. This does not include the hot water piping that is routed to the lavatories and around the two restrooms along the wall. This piping will all be removed.
6. FIXTURES
All fixtures, floor drains, etc. will be as shown on plumbing drawings. All floor drains will be complete with trap guards to prevent sewer odors from entering the building and will be located in the same locations as the existing where applicable. There are four floor drains total in the existing restrooms and a new floor drain in the janitors closet and the new individual restroom. Most fixtures will be cast iron, vitreous china, or 18 gauge stainless steel with cast brass faucets. Water closets will be wall mounted with chair carriers, and all flush valves on water closets will likely utilize battery operated sensor valves. Urinals will be wall hung and the flush valves on these urinals will likely utilize battery operated sensor valves. Lavatories will be both countertop and wall mounted as indicated on the architectural plans with single handle sensor faucets and ASSE 1070 approved mixing valves. All fixtures will be low consumption for water efficiency in order to reduce on utility costs. New custodial sink will be floor mounted terrazzo type. The existing custodial closet contains a wall mounted emergency eyewash fixture and we will plan on including one in the new custodial closet. Eyewash shall be complete with a mixing valve to provide tepid temperature water to the fixture. Hot water will be provided through an electric water heater (approximately 40 gallons) located in the janitor’s room. The water heater will be complete with expansion tank. The water heater will utilize a hot water recirculating pump to maintain water temperature and will be circulated to the furthest fixtures.

HVAC SYSTEMS
1. DESIGN CRITERIA
All HVAC systems shall be designed in accordance with the 2018 International Mechanical Code, ASHRAE 90.1-2007, and the State Fire Marshal Regulations, Latest Edition.
Outdoor Design Conditions Summer 97 FDB, 78 FWB Winter 22 FDB
Indoor Design Conditions Summer 75 FDB, 50-60% RH Winter 70 FDB
2. GENERAL
The existing HVAC systems serving the first floor is a large single zone unit that provides conditioned air over a large area of the floor. Smaller individual temperature control zones are not possible with the existing system in the current configuration.
The existing system can be modified to provide air to the renovated areas. However individual temperature control and ventilation cannot be provided unless more extensive modifications are made to the existing systems.
Several options will be listed for consideration in this feasibility study.
Option 1 will consist of minor modifications to the existing duct systems to include new diffusers for each new space. This will not provide for any individual temperature control. Spaces like the Multipurpose Room and Meeting Room may not be comfortable when filled with people for extended periods of time. Office spaces will not be individually controlled. The main thermostat is the only temperature control and it will not react to changing conditions in the individual spaces.
Option 2 will be similar to Option 1, however supplemental conditioning systems will be added to the large spaces like the Multipurpose Room and Meeting Room to offer some level of temperature control for these spaces. Additional supplemental units could be added if more temperature control is required in other spaces.
Option 3 requires an HVAC system replacement and upgrade. The existing system should be replaced with a central variable air volume unit. The system will include variable air volume terminal units that control the temperature in the individual spaces. The VAV system will ensure that proper outside ventilation air is provided to each space. Option 3 is the recommended system type for this building renovation. Please note that it is considered outside of the feasibility scope of this project and budgeting has not been provided for this option. A further study of the HVAC systems would be required to provide a scope of work and an opinion of probable cost for this option.
3. OPTION 1
The existing ductwork will remain in place. New ceiling diffusers and plenum return grilles will be installed from the existing ductwork as required for each new space.
4. OPTION 2
The existing ductwork will remain in place. New ceiling diffusers and plenum return grilles will be installed from the existing ductwork as required for each new space.
Two 3 ton ductless split heat pumps will be installed in the Multipurpose Room 118. The condensing units will be located on grade.
One 1-1/2 ton ductless split heat pump will be installed in the Meeting Room 124. The condensing unit will be located on grade.
5. EXHAUST SYSTEMS
The existing exhaust system will be utilized to provide exhaust air for Restroom 126 and Janitor/ Storage 125. A ceiling grille will be installed and ducted to the existing central exhaust system.
6. AIR DISTRIBUTION SYSTEMS
Ductwork will be galvanized sheet metal per SMACNA Duct Construction Standards. Ductwork from air handling units to ceiling grilles will be low pressure galvanized metal and flexible duct runouts at grilles. Air distribution will be selected as appropriate for the spaces served from a durability, noise and air delivery standpoint.
7. INSULATION
Indoor duct insulation will be fiberglass with an all service jacket.
Refrigerant tubing and condensate drains will be insulated with ¾” wall Armaflex and the outdoor pipe insulation shall be covered with a corrugated aluminum jacket.
8. CONTROL SYSTEM
The existing control system will not be modified for this renovation. Option 2 will require a stand alone thermostat for each split heat pump. The existing central control system will provide start and stop control to each split heat pump for after hours and nighttime setback.
