PURPOSE 2. ORGANIZATION OF DESIGN REQUIREMENTS 3. DESIGN PRINCIPLES Killeen Independent School District Design & Construction Standards 5 VERSION 1.1 APRIL 15, 2015 PURPOSE AND PRINCIPLES 1. PURPOSE The Killeen Independent School District is committed to creating high-quality educational environments – places that provide well-planned, high-performing, healthy school environments that foster student achievement and well-being, as well as being centers of community. The “Facilities Design and Construction Standards” establishes and ensures consistent representation of requirements and quality standards for those environments to all members of the Design Teams for KISD facilities. It is based on the current curricula, teaching methodologies, student groupings, structural functionality, intended use requirements, and site constraints of the District. It reflects the District’s experience in building and operating schools to balance the needs for instructional functionality with aesthetics, practical comforts, sustainability, accessibility, ease of maintenance and operation, and assurance of safety so that all students, staff and community members feel welcome, safe, and proud of their schools – all while reflecting the wise and efficient use of limited land and public resources. Architects and engineers shall follow the requirements and standards presented here for the planning and design of renovations, modernization, reconstruction, and new school construction. The intent of the FDCS is to serve as a foundation for all phases from concept to occupation, not to stifle creativity or innovation. If a design professional feels that varying from specific requirements, while still meeting the intended design requirement and it is desirable for a specific project, it may be possible to incorporate the variations into the design with written approval of the District’s Executive Director for Facilities Services, Deputy Superintendent, or Superintendent. Email is sufficient if the full content is included as a documented element of the amendments, change order, or RFI process. The FDCS incorporates and complements the policies, requirements, and standards of other KISD documents that direct the design of school facilities (you may CTRL+CLICK on the links below). The Facilities Services Directorate will update these policies, requirements, and standards on a quarterly basis. We will publish interim changes periodically and post them as a change to the existing document until the District Superintendent reviews and elects to incorporate all changes into this document.

ORGANIZATION OF DESIGN REQUIREMENTS Killeen Independent School District Design & Construction Standards 6 VERSION 1.1 APRIL 15, 2015 The content of the “Facilities Design and Construction Standards Manual” is divided into four Parts: a. b. c. d. Part 1 – general items, purpose and principles Part 2 – functional and relational planning and design criteria; including general environmental and sustainability issues; and Part 3 – detailed information on material choices, system design criteria, requirements, by Specifications Divisions on each major technical discipline. Part 4 – includes submittal checklists for the various project phases. The references and links to requirements and standards that KISD includes in design and construction include: e. The Code that governs the educational specifications, capacity, size, and number of functional spaces of each school project is the Texas Administrative Code, Title 10, Part 2 (Texas Web Link: School Facilities Standards Education Agency), Chapter 61 (School Districts), Subchapter CC (Commissioner’s Rules for Construction on or after Concerning School Facilities): January 1, 2004 f. g. “Guide Specifications:” KISD applies standardized construction specifications in CSI format to define the materials and systems acceptable to the District, including considerations of economy, performance, maintenance, and operations. The Guide Specifications often include alternative choices for materials and equipment. These Guide Specifications must be edited by the Architect and reviewed for approval by the KISD Executive Director Facilities Services to ensure they meet the needs of each specific project. “Standard Technical Drawings” (Standard Drawings.): These are construction details with standardized specifications adopted across the district that provide District-wide consistency for materials, supplies, operations, and safety standards. As technology, design, and energy efficiencies increase over time, these drawings will supplant older or inefficient drawings as adopted by the district. Killeen Independent School District Design & Construction Standards 7 VERSION 1.1 APRIL 15, 2015 DESIGN PRINCIPLES A. B. C. D. E. F. G. Learning Environment: The integrated design of district educational facilities will provide instructional spaces that best facilitate student-teacher interaction in the educational process. As methods of instruction change or become increasingly interactive and collaborative so, too, must the space in which the learning is to take place. Therefore, the available space must provide flexibility to accommodate different teaching styles, a health-enhancing environmental ambience, and enable multiuse for all curricula if practical. Architectural Quality: The central Texas region is rich in history, fauna, and its geological formations. Bringing these qualities and elements into the site plan and design of the facility will tie the appearance and character of each school to our surrounding culture. The structural aesthetics should be pleasing and stimulating to students, teachers, parents, and the surrounding community while providing a welcoming and attractive place to visit or to spend the day. In the planning and design for the reconstruction or renovation existing facilities and grounds, the new materials and design of the structures will be architecturally compatible with the existing buildings and site. As the population of the district continues to grow, the designs of our structures, site placement, traffic and pedestrian circulation as an integral part of the district’s Capital Improvement Master Plan. Innovation in the “Learningscape”: The core functionality of the KISD educational space focuses entirely on student learning through user-centered planning and design for all schools. Input from the faculty, administration, and local community are integral parts in the design process and center around collaborative learning spaces; ease of accessibility; integration of faculty and students into the day-today learning; and flexible environments to support a range of learning activities. Enabling criteria include, but are not limited to cheerful and imaginative spaces that are open and inviting to occupants; variety in materials, colors, and structure that excites the senses; inclusion of small learning communities; select site placement; and quality and enduring building materials. Pride in Ownership: Ownership begins with an individual sense of belonging and uniqueness and grows by fostering a desire to contribute the common goals of success and synergy among the whole. From concept through occupation, the design of our educational and supporting administrative facilities must include a sense of pride from the materials, colors, aesthetics, and prominence in the community and site placement as they will serve as a landmark for 50 years or more. Flexibility: The design of schools and facilities must anticipate future growth across the district – not designing for “the now.” The intended use of a structure must be conceptualized “outside the box” as changes in systems, instructional methods, technology, equipment, and requirements will certainly impact future costs and designs. The “edge” or undefined boundary of education is constantly expanding, but our facilities must remain affordable in scale and use. Planning efficient multi-use spaces (studios/activity based learning vs. classrooms/lecture based learning), structural/mechanical/electrical/plumbing/safety/security “tie-ins” for additional buildings, and creating small learning communities and options for unforeseen changes are imperative for future design considerations – built in flexibility. Learning Environments: The learning space is equally as critical as the process of learning itself. The design of schools must consider and integrate varying levels of educational methods, elements, and scale of audience. Providing the opportunity for students to create and learn simultaneously and bridge the gap between knowing and knowledge through provisions in space, interactivity, and technology from an individual level to a collective group level. Building facilities with this concept in mind enables the reduction or increase of actual or perceived scale of the learning environment for students. These integrated learning environments with common affinities, such as common curricula, digital device interconnectivity (BYOD), themed educational programs and methods, multimedia, age, and grade are all elements we must consider in future design of schools and facilities. Accessibility: District facilities must accommodate all students, staff and community members including the physically disabled and wheelchair-bound, deaf, visually or emotionally impaired – inclusive rather than exclusive in design. Design shall allow for construction and material tolerances to Killeen Independent School District Design & Construction Standards 8 VERSION 1.1 APRIL 15, 2015 H. I. J. K. L. accommodate dimensional requirements set by ADA and other codes. Do not design to minimum or maximum requirements, thus risking potential non-compliant designs. Safety and Security: Schools must be safe and secure without appearing prison-like. Structures, fences and site amenities shall be designed to maintain safety, prevent unauthorized access and deter vandalism. Opportunities to climb to gain access to other floors, roofs, etc. shall be eliminated. Community Focus: The school, as the center of the neighborhood, must be accessible on evenings and weekends for joint use of facilities by the community and provision for securing the rest of the site shall be implemented. The design of our facilities provide for expanding educational, leisure, and interconnected multi-media opportunities thereby increasing potential revenue and partnerships with other institutions or organizations as part of a greater community-based facility. Land Use and Site Planning: As the surrounding communities continue to grow in population, land is becoming a premium for schools and support facilities. Unless purchased in advance of pending developments, “prime” land for ideally siting schools and the required grounds for elementary, middle, and high schools are difficult to predict, fund, and acquire for future construction. Once the developer acquires land for construction, the District must innovatively site buildings, playgrounds, athletic venues, vehicular circulation, and parking to meet and achieve educational requirements of the community. Sustainability: The District must assertively address the design, renovation, and construction of existing and facilities for their long-term requirements and environmental impacts, recycling, water conservation and energy efficiencies. The efficiency of every facility should improve upon the previous design and make every effort to highlight to the students and community that the District will do what is taught in being stewards of our future resources. Maintainability: From the concept design through the construction phases for every facility, the District will strive to continually integrate material solutions that will minimize future maintenance requirements. As a reference, over a 30-year period, the initial building costs account for approximately 2% of the total, while operations and maintenance costs equal 6%, and personnel costs equal 92%. Selecting materials that enable maintenance savings can be reinvested in educational initiatives or facility improvements. Killeen Independent School District Design & Construction Standards 9 VERSION 1.1 APRIL 15, 2015 LIFE CYCLE SCHEDULE: It is critical to include the “Total Cost of Ownership” (TCO) when specifying materials, systems, and equipment for educational facilities. You can save very small percentages up front and wind up paying higher replacement costs more frequently if a balance of expectations and fiscal obligation is not achieved. Materials and systems installed in facilities, typically, do not have the same 50-year designed life cycle as the structures in which they are placed. This schedule codifies the industry average life cycles for materials and systems typically found in educational and administrative facilities. Decisions to accelerate the life cycle replacement or defer replacement timelines vary due to many tangible and intangible factors to include mean time between failure (of system or components), fiscal timing, parts availability, cost of procurement, cost of maintenance, cost of use, frequency of repairs (reliability), frequency of use, material and technology upgrades, code compliance, environmental constraints, and many, many more. The purpose of life cycle analysis is to provide decision makers with the requsite information required to fully support the educational process by providing equipment and building components with: 1. mechanical resistance and stability 2. safe to operate and in mechanical functionality 3. hygienic and promote a healthy and clean environment 4. minimal noise impact 6. energy efficiency for lighting, heating, cooling, and maintenance The image below depicts the subsequent three pages of component useful life cycles in years.

This space left intentionally blank. Killeen Independent School District Design & Construction Standards 12 VERSION 1.1 APRIL 15, 2015 Killeen Independent School District Design & Construction Standards 13 VERSION 1.1 APRIL 15, 2015 DEFINITIONS: • A/E, Architect/Engineer: The lead consultant for the master planning, programming and/or design of new facilities. • Facilities Audit/Assessment: Provides a source for identifying the existing physical condition and functional performance of buildings and infrastructure, as well as their maintenance deficiencies. • Board: The Board of Trustees, current, elected, or appointed. • Commissioning: The process of placing buildings and building systems into service. The thorough validation of operation of all building systems to assure completeness and optimum performance in accordance with the architectural and engineering design and specifications. The Commissioning and validation task is conducted three times in the first year: prior to substantial completion and before the district takes possession of the structure and at full occupancy load at the historical peak energy demand periods for heating and cooling (normally winter and late summer). • Consultant(s): Planning and/or design professionals contracted by Texas Independent School District to create master plans, programs, and construction documents for building or renovating school facilities. Consultants include but are not limited to Attorneys, Architects, Engineers, (Structural, Civil, Mechanical, Electrical, and other), Landscape Architects, Urban Planners, Kitchen Designers, Ecologists, Environmental Abatement Engineers and Communications/Technology. • Design Charrette: An intense period of design and/or planning activity conducted by specifically selected and appointed stakeholders in the school district to ensure the design specifications and requirements are holistic and inclusive and meet the administrative or educational specifications for the facility. The inclusiveness of the team cannot be so large that it becomes unmanageable and unproductive. For example, a new elementary school design charrette team will consist of administrator (principal or assistant principal, select teachers (based on type of curriculum and skills included in the new school), maintainers (senior technicians), architects, engineers, custodians (district supervisor or zone foreman), budget, food services, procurement, and the facilities services project management team. The inclusiveness promotes joint ownership of solutions and establishes a balance between cost, needs, wants, and functionality. • Educational specifications: Serve as a written communication from the owner or the educator to the design professionals particularly the architect, describing the educational activities that school plant should accommodate, present and future. • Facilities: All district-owned physical or real property and grounds. • Faculty: Current Texas Independent School District teaching staff. • Guidelines and Standards: Board approved methods, procedures and instructions to direct consultants in the programming, planning, design and construction of new facilities. Also district standard materials and systems for installation in new school facilities. Killeen Independent School District Design & Construction Standards 14 VERSION 1.1 APRIL 15, 2015 • HVAC Systems: The Heating Ventilation & Air Conditioning mechanical systems, components and controls that provide ventilation, heating, cooling and humidity control within a building or set of buildings. • Maintenance: The routine operation, inspection, adjustment, cleaning, testing, general care and repair/replacement of facilities to assure their optimum performance at all times. • Master Plan: A detailed, comprehensive study and report defining the ultimate built environment for a given site. • Operations: The day to day workings of a facility including the housekeeping and routine use of facilities. • Planning team: The collaborative collection of persons responsible for planning, programming, and design of new or renovated school district facilities. • Programming: The planning and organizational efforts to establish a set of criteria for the design of building and other improvements. • Scope or Scope of Work: A written description of the work to be accomplished. • Site: The physical location for a proposed improvement. • Staff: Current Texas Independent School District administrative staff. (Non-instructional personnel) • Test and Balancing Report: A report generated by an independent, certified testing and balancing company. The report reflects the field verification of mechanical (and other) systems including water flow, airflow, controls, dampers, valves, actuators, and other items as based on the A/E's design requirements. The intent of the work is to verify the equipment is performing as designed. • Value Engineering: The process of evaluating the performance of materials, finishes, systems and components against their cost over the lifespan of a facility. Value engineering should be done in the early stages of the designing of a project. Killeen Independent School District Design & Construction Standards 15 VERSION 1.1 APRIL 15, 2015 Project Scope and Development Design Team Requirements: A. The Superintendent shall appoint a design team to assemble and participate in the design charrette for the project. The team shall ideally have the following members: o o o o B. Campus representatives (principal or designee, optimally w/an educational background plus one representative from each major department: math, social studies, P.E., science, fine arts and special programs as required). District Representatives may include (but is not limited to): § Maintenance Technicians § Facilities Planning and Construction § Information Technology (data, computers, projection, systems, networks) § Fine Arts (acoustical, lighting, video, platforms/stages, art, etc.) § Environmental and Energy Management § Food Services and Nutrition § Security & Safety § Transportation § Athletic Department (fields, gyms, locker rooms, weight training, etc.) § Custodial and Grounds Care External District Representatives may include: § Parents or Citizen's from the neighborhood where the facility will be built. § The commissioned Architect and Engineer team. § Public-Private Partner And others deemed desirable by the superintendent. Design Team Tasks and Responsibilities: The owner representative and architect (O/A) for this project shall be the team co-leaders for the design of the project. The team shall meet regularly to review the program and designs of the new facility. This should occur at intervals that reflect the O/A’s planned review with the administration and board. A clear and concise schedule for the design of the school shall be established. The schedule shall include review of preliminary, design/development, and construction document reviews shall be scheduled and executed with the committee and The A/E consultant shall conduct a review of the written program with the committee to establish a clear understanding of the proposed facilities. As the work progresses the architect shall conduct the following: 1. 2. Preliminary plan work session with schematic plan review(s). These reviews shall provide the committee an opportunity for input into the planning process within the framework of the program. A discussion of the general style and character of the school shall occur. A cursory review of the site information shall be done with the committee. The commissioning agent shall provide input to the architect and engineers to assure building systems are appropriate and inclusive. The site analysis shall be discussed and the A/E's rational for the siting of the building(s) shall be discussed. Final preliminary plan shall be reviewed with the committee prior to board review. Design Development review. As the floor plans, elevations and building sections are executed by the architect, appropriate reviews shall be conducted with the committee. These reviews shall be informative and help committee members understand the spaces within the structure, the vocabulary of materials and the building systems to be included in the project. The architect's cost estimates shall also be reviewed and understood by the committee. Final design development shall be reviewed with the committee prior to board review. Killeen Independent School District Design & Construction Standards 16 VERSION 1.1 APRIL 15, 2015 3. 4. 5. 6. Final Contract Documents shall include a series of reviews that include mechanical, electrical, Structural, plumbing, communications, and other technical area reviews to assure compliance with the district guidelines and standards. At least one of these reviews will afford the opportunity for the design committee to examine the plans and specifications as they are completed and before the board reviews them. The design committee is to provide input into the design but as the plans progress the role of the committee becomes more to review and not design the building. This is the job of the architect. Team Summary Report When the construction and occupancy is complete, the committee will assemble one last time for a summary evaluation and discussion, revisiting the process and making any comments, suggestions, notes, ideas on how the process could be improved. This evaluation should result in a written report submitted to the Facilities Planning and Construction Department and should occur within one year of the completion of the project. Killeen Independent School District Design & Construction Standards 17 VERSION 1.1 APRIL 15, 2015 KISD Project Process Flow Task Name District Requirements Assessment Identify Available Land in Proximity to Meet Requirements Develop FF&E (Facilities/Purchasing/Budget/Campus Representatives) Superintendent Approves SOW/REQS Prepare Land Acquisition Board Documents Board Approves REQs & Land Procurement A/E/C Board Document Preparation Definition Occurs as a result of district growth, rezoning, school closures, and anticipated/forecasted Capital Improvements to meet educational needs. The administration and Board of Trustees has a dialogue to identify requirements for land/property in closed sessions during meetings and workshops. This dialogue helps to establish or determine suitability, acceptability, affordability, and to provide guidance for acquisition actions. This single programmatic step provides the most critical information from which to begin the Capital Improvements Process. Reference TAC, Title 19, Part 2, Chap 61, CC, Rule §61.1036 and §74.1. District coordinates through a land broker or procurement representative to identify sufficient acreage to meet the anticipated requirements (ES = 12-15 acres, MS = 25-30 acres, HS > 70 acres). Variances must be taken into account based on the supporting infrastructure (sewer, water, power, roads), useable terrain, code & environmental restrictions, and cost per acre. District procurement planning begins with a like sized facility as a baseline for FF&E and is tailored based on the occupational and educational requirements being met by the construction of the facility. To ensure the district soundly establishes the standards and requirements for each project, the Superintendent receives a decision briefing to approve the Scope of Work for the landscaping, material selection (interior & exterior), and occupational expectations, educational capacity, security, IT infrastructure, and energy efficiencies. Additionally, this will include , the number and types of students and faculty who will use the facility, the number and types of spaces, any special equipment requirements, and specific objectives that the end product will enable. District staff prepares the appropriate documents (letter of intent, land offers, legal documents, surveys, rental agreement, lease, or memorandum of agreement) to present to the Board of Trustees at a Workshop to gain their support or clarify requirements to justify the acquisition of land/property meets the future anticipated needs of the district for the best available value. Due to the level of fidelity and amount of information provided, it is best to present this as an information item to gain support for approval or consent at a subsequent Board of Trustees Meeting. The ultimate decision for expending capital resources lies with the Board of Trustees who will make an informed decision based on the recommendations of the Superintendent and the staff. The district acquires and maintains professional services as a “Pool of Professional Services” using proximity to the district, cost/affordability, past performance, and portfolio as critical selection criteria.

KISD’s Design and Construction Standards to the consultants who design facilities for the district. This is intended to be a “working document” and the district welcomes your comments in our continuous improvement efforts to maintain a relevant document. Comments regarding improvement of standards may be submitted to Bonnie Tomczyk by email at Bonnie.Tomczyk@killeenisd.org. Facilities Services will review and consider input on a weekly basis during it’s Monday morning Strategic Planning Meetings. If any standard differs from the consultants’ professional opinion or experience as to the proper materials, components, or equipment for the project under contract by the consultant, the consultant is requested to communicate that concern through the KISD Project Manager in writing at the earliest possible phase of the project for review during the weekly Project Update Meetings. Nevertheless, no provision herein shall alter the contractual or fiduciary responsibility of the consultant or of Killeen Independent School District, as executed in the Owner-Consultant Agreement. Neither shall the absence of a particular instruction or detail relieve the consultant of the responsibility to deliver a comprehensive professional service or final product in accordance with the most current (2015) International Building Codes and the International Existing Building Codes. KISD encourages innovative quality design of the architectural and engineering components of the work, but the following standards listed are not optional. The A/E may propose other materials and systems for KISD consideration and written approval. KISD encourages and supports sustainable architectural design. Minimal maintenance requirements, long life cycle, and flexible designs are paramount to the design of buildings that will last for the next 50 years. During the pre-design and design stages, discuss with the district possible options for meeting Green Building Council’s “LEED” or Green Building Initiative’s “Green Globes” Certification criteria in every facet, and address recycling of waste materials and use of recycled and regionally manufactured products. Killeen Independent School District Design & Construction Standards 31 VERSION 1.1 APRIL 15, 2015 Division 01 General Requirements Section 01 05 00 – General Requirements A. B. C. D.
