APPENDIX

PREFACE

A. BACKGROUND

The Architect of the Capitol (AOC) is dedicated to being the builder and steward of the heritage assets of America’s Capitol while serving Congress and the Supreme Court. AOC works tirelessly with ingenuity and craftsmanship to maintain the historic fabric found throughout the Capitol buildings and grounds.

Purpose: The purpose of this manual is to define the role of the Architect-Engineer in the delivery process for construction, renovation, and rehabilitation projects and to enumerate the project management responsibilities at AOC. The Architect- Engineer may be an AOC employee or a contractor.

Applicability and Reference: The A/E Design Manual is applicable to construction, renovation, and rehabilitation projects of all sizes and complexities undertaken by AOC. The requirements are mandatory unless specifically stated otherwise in the text. The AOC Design Guide provides additional direction for design standards. This document is available through the project manager.

The term “Architect of the Capitol” as used in this manual does not refer to the person appointed as Architect per 2 USC §1801, but rather the organization acting on this person’s behalf in carrying out the Agency’s functions.

The A/E and the project team shall not make the procedures set forth in this Manual and its Appendices part of any Construction Document by reference. Required text for Construction Documents is available within agency guide specifications available on agency servers.

Stewardship: AOC has identified stewardship as one of the agency’s core values. AOC's staff and contractors undertake all design and maintenance efforts in the context of the protection and preservation of the Capitol. AOC designs and constructs new facilities for very long operational lives, using high quality durable materials that return value from their higher initial cost through reduced replacement and maintenance needs. AOC staff and contractors shall be keenly interested in the energy consumed by these facilities, and must consider value-engineering options, life cycle cost analysis, and sustainable design features.

Historic Preservation: The Historic Preservation Officer (HPO) is responsible for ensuring that all heritage assets are properly protected during any modifications or upgrades undertaken by AOC. All AOC Jurisdictions planning or carrying out design or construction projects in spaces including or adjacent to any work of fine art, decorative art, or architectural features, shall consult the HPO and AOC Curator so that appropriate ways to minimize or monitor the impact of the project on the heritage assets can be determined.

There are important distinctions between renovation work and rehabilitation work. Renovation has a connotation of major new work in the historic building, while rehabilitation refers to work with the original design, space, décor, etc. which are intrinsic to the historic building and then, through rehabilitation, use those resources in the new use. The term rehabilitation shall be used to refer to most projects, while renovation projects shall refer to systems renovations.

B. ASSOCIATE ARCHITECT-ENGINEER’S ROLE

The Associate Architect-Engineer’s (AA/E) role as a consultant to the Architect of the Capitol is to provide comprehensive, professional services that support the operations of the Capitol while respecting the historical significance of the buildings and grounds. The AA/E shall be responsible for the professional quality, technical accuracy, and coordination of the project design and construction to include the preparation of Construction Documents and management of other services furnished under the Contract. The Architect uses professional consultants to bring the latest and most up-to-date technology to the project with the intent of reducing building costs, decreasing energy use, and supporting a sustainable environment.

The value of the architect’s contribution extends far beyond form and aesthetics. It can influence the perception, performance and value of the facility. The AA/E is responsible for defining the project through consideration of function, aesthetics, economics, environmental, life safety and regulatory requirements while appropriately balancing these considerations in the final design. Where appropriate, the AA/E shall offer alternatives that ensure the most value derived from an investment. The Architect expects objective ideas from the AA/E without prejudice for their own desires. The AA/E shall look beyond the immediate requirements to ensure the design provides a cost efficient design with functional spaces. The design must be functional, safe, economical, and respond to needs of the client as well as reducing the operating costs by maximizing the efficiency of the building.

AA/E Licensure: Architects/Engineers licensed to provide professional services for the design/construction industry in any state, District of Columbia or territory may provide professional services for the Architect of the Capitol. A professional license is one that is recognized by a state, District of Columbia or a territory. The license shall be current and in good standing with a jurisdiction through the date of project completion. Where a license has expired, the Architect/Engineer shall either reinstate the license or partner with another licensed professional who will seal and sign the contract documents. The A/E is not required to maintain an active office within the state or District of Columbia while performing work for the Architect of the Capitol.

AA/E’s Team: The Architect endeavors to contract with AA/E’s that possess the knowledge, skills and resources to provide services for a particular project. The AA/E shall evaluate project scopes and assemble an experienced, competent team of professionals and technicians who have the knowledge to address the design challenges and execute the work associated with the project. The personnel shall have knowledge of design and construction to include means, methods and techniques required to execute the work. If the AA/E does not possess the necessary disciplines required to perform the work within its firm, they shall subcontract with responsible firms to provide the additional services. AA/E’s shall only practice in the disciplines for which they have received a professional license and continue to maintain a comprehensive professional practice.

For example, Landscape Architects shall not be hired to perform the work of Civil Engineers unless the Landscape Architect also maintains a license as a Civil Engineer and practices within the discipline.

AA/E’s are required to become familiar with the project type, the common design and engineering practice elements associated with the work and the locality prior to beginning the work. The Architect reserves the right to require AA/Es to obtain additional services or partner with other professionals to obtain an expertise in a particular discipline, building type or aspect of the construction industry. This requirement shall not be subject to an increase in the compensation after start of the project.

AA/E fees shall include all costs associated with management of the work to include but not limited to all labor, material, equipment, furnishings, travel, meals, lodging, office operations, consultant services, printing, and all associated costs.

AA/E Document Certification: The AA/E is responsible for providing contract documents that focus on constructability.

Documents must be comprehensive in nature to cover all aspects of the design. The AA/E shall use the latest technology such as Building Information Modeling (BIM) and 3D software in the development of contract documents. The AA/E shall develop documents that are intended for construction and use by Contractors; not just a compilation of drawings that reflect design intent. Documents shall reflect the Scope of Work through the use of the Architect’s standards, including, but not limited to, this Manual and the AOC Design Guide. The AA/E shall manage consultants’ work to reflect a consistent, cohesive set of documents. Documents shall be produced in a timely manner and tailored to the project’s needs, budget and functional requirements.

The AA/E shall seal and sign each drawing associated with their discipline and shall also seal and sign the professional seals section in the Project Manual.

Professional Extended Responsibility: The AA/E shall, without additional compensation, correct or revise errors and deficiencies in the project design, the Construction Documents, and other services furnished under the Contract.

The Government’s review, approval, acceptance of, or payment for any of the services required or rendered under the Contract, shall not be construed as a waiver of any rights under the Contract or of any cause of action arising out of the contract performance. The AA/E shall perform Quality Assurance and Quality Control operations that endeavor to reduce or eliminate potential misinterpretations. The use of a particular criteria requirement, unless specifically prescribed by the Government, shall not release the AA/E from responsibility for professional quality and technical accuracy.

Monitor Cost: The AA/E shall review the initial cost and the cost at each phase of the project and inform the Architect if the project is feasible based on the Scope of Work, which includes, but is not limited to, the Program of Requirements, Construction Methods and Techniques, Materials, and other related factors that affect the completion of the work. The AA/E shall advise the Architect through written communications if the project will exceed or is likely to exceed the funding limitation based on the Scope of Work and if so, shall provide suggestions that will produce a complete and functional project within the available funding. An Option(s) and/or an Alternative(s) may be used to reassign portions of the work to other years when additional funds may be available to complete the remaining work.

The AA/E shall monitor the project cost during each phase of the work. The AA/E shall provide written communication to the Architect at the end of each phase that confirms the scope of work and project cost conforms to the POR and funding limitation, respectively. The AA/E shall immediately alert the Architect at any time during the Design Phases when the AA/E makes significant changes to the Scope of Work that effect the functional requirements or project cost. The Architect (Project Manager) shall review the AA/E's Probable Cost of Construction at the end of each Design Phase of Work. The AA/E shall take into consideration all unique operational requirements associated with performing construction on Government property when preparing cost estimates. The AA/E may request a change in scope of work or selection of materials if the AA/E believes these factors may cause the bids to exceed the funding limitation by more than ten percent.

In the event bids are solicited for a project and the bids received exceed the funds available by more than ten percent, the AA/E shall be responsible for the cost of redesign, preparation of the contract documents and re-solicitation of bids for the work should the Architect determine the AA/E’s performance, work and other factors contributed to the cost increase. When the Architect decides not to solicit bids or proposals following the preparation of Contract Documents or the Bid Solicitation process is unreasonably delayed due to unavailability of funds, the Architect shall prepare another independent Probable Construction Cost Estimate for the Work. This PCCE shall be used in lieu of previous Probable Construction Cost Estimates, bids or proposals to determine the base line for the AA/E’s compliance with the funding limitations.

Bid Options and Alternates: During the design process, the AA/E shall compile a running list of potential options and alternates for use in making adjustments to the contract cost. This list shall be submitted to the Architect with each phase submission of the work. The Options and Alternates may be instituted during the formulation of bidding documents should the Probable Cost of Work exceed the available funds.

Bid Options may take the form of future phases of work. The determination of Options to be included as Bid Options shall ensure that the resultant Base Bid scope shall satisfy the fundamental Government needs detailed in the appropriation and Scope of Work while simultaneously ensuring that bids are within funding limitations. The number of Bid Options and Alternates shall be minimized to preserve bidding practicality. The Architect shall review and approve the formulation of Options and Alternates. The Architect shall endeavor to determine the necessity for Bid Options and Alternates at the earliest possible point in the design process to allow full integration and coordination of information during the preparation of construction documents. The AA/E shall be responsible for altering the contract documents to delineate the Options (to include creating phases of work) and Alternates at no additional cost to the Architect.

Errors and Negligent Performance: The AA/E shall endeavor to reduce design errors and omissions by instituting a Quality Assurance and Quality Control (QA/QC) program that shall be maintained throughout the Design Process. The AA/E shall submit their QA/QC program to the Architect for review and approval prior to beginning work on a project.

Should Design Errors or Omissions occur during the construction period that result in damages or extra cost to the Government, the AA/E performance and design efforts shall be evaluated to determine the potential for AA/E financial liability. If the Architect determines that the AA/E is financially liable for a design deficiency, the Architect (Contracting Officer) shall advise the AA/E of the findings and any AA/E financial liability. The AA/E shall be liable to the Government, in accordance with applicable law, for damages to the Government caused by the AA/E’s negligent performance related to any services furnished under the AA/E contract. The process for handling a settlement shall be addressed on a case-by-case basis as determined by the Architect (Contracting Officer, Project Manager) with input from the General Counsel.

SECTION 1 DOCUMENTS

1.3. DRAWINGS

1.3.1. Sheet Numbers

The AA/E shall organize drawing sets and utilize system formats specified in the Uniform Drawing System (UDS) as published by the Construction Specifications Institute. The AA/E shall use the UDS for the sheet number and computer file suffix portion of the file name. The AA/E shall enter the number generated by the UDS below into the title block drawing number box. Complete copies of the standard may be obtained from CSI. The AA/E shall build a sheet name based on the following:

• Discipline Designation: At the highest level, this designation shall denote the major discipline used for the file (sheet) by the AA/E. The sheet designations and drawing set are ordered as follows:

G General H Hazardous Materials V Survey information C Civil B Geotechnical L Landscape S Structural A Architectural I Interiors Q Equipment F Fire Protection P Plumbing M Mechanical E Electrical T Telecommunications R Resource X Other Disciplines Z Contract/Shop Drawings O Operations

If the AA/E desires to designate additional sheets within a section, the two character designations may be used as indicated in APPENDIX B. If a two character designation is used anywhere in the set, then every discipline and sheet in the set will use two character designations.

• Sheet Type Designation: The AA/E shall use a single numerical character to designate sheet type. Discipline designators may use all sheet types. The sequence listing is used for binding order and set assembly:

0 General - Symbols legend, notes, etc.

1 Plans - Horizontal 2 Elevations - Vertical views 3 Sections - Section views 4 Large Scale Views - Plans, elevations (interior), or sections that are not details 5 Detail 6 Schedules and Diagrams 7 User Defined 8 User Defined 9 3D Representations - Isometrics, perspectives, photographs

• Sheet Sequence Number: The sequence number simply identifies the sheet’s location in the discipline series. Sequence Numbers will be created in the following manner: DDTNN, where “DD” is the one or two letter discipline designation;

“T” is the single number designation for drawing type (see APPENDIX B for examples of sheet numbers); and “NN” is the two number designation for the order. The following examples demonstrate what AA/E’s shall enter into the sheet number box in the title blocks:

G001 Cover Sheet A301 Architectural Sections - Sheet 1 AD101 Architectural Demolition Plan - Sheet 1 EL103 Electrical Lighting Plans - Sheet 3 in plan series M602 Mechanical Schedules -Second sheet of schedules

With some large building projects, AOC prefers to number sheets in a manner to group sheets by the floors of the building. In these projects, the sheet sequence convention is modified as follows: DDTFFNN where “DD” is the one or two letter discipline designation; “T” is the single number designation for drawing type; “FF” is the two character designation for the floor (see APPENDIX B for list of floor designations); and “NN” is the two number designation for the order. The following examples demonstrate what AA/E’s shall enter into the sheet number box in the title blocks:

G00001 Cover Sheet.

AE32010 Architectural Sections – Second Floor, Sheet 10 AD1RF01 Architectural Demolition Plan – Roof, Sheet 1 EL1SB03 Electrical Lighting Plans – Sub-basement, Sheet 3 in plan series M60002 Mechanical Schedules – All Floors, Second sheet of schedules

• CAD File Numbers: The UDS number or reference file name, coupled with the AOC project number and a linking underbar (_) produce the MicroStation File name. The AA/E shall enter this number into the title block field that is labeled as CAD File Number. All sheets in the drawing set are completed in separate CAD files. Reference files do not use number designation to avoid confusion with sheet files For example:

1.4. COMPUTER AIDED DESIGN

1.4.1. Introduction

AOC utilizes MicroStation® software, Version 8 (2004, XM, i), by Bentley Systems, Inc. This section specifies standards to be utilized for computer aided design (CAD) submittals submitted to the AOC for standard graphic files that do not include database linkages or use of Bentley System's Bentley Building Application environments (Building Information Modeling (BIM)). CAD input is required for all disciplines including architectural, electrical, landscaping, civil, fire protection, telecommunications, plumbing, mechanical, and structural plans, elevations, sections, details, riser diagrams, and schedule sheets.

Unless otherwise defined in the AA/E’s contract, design work and submittals shall be accomplished using MicroStation-based software. Selected projects shall require the use of Bentley Building Architectural, Electrical, Mechanical, and Structural BIM applications unless otherwise specified. Additionally, several principal buildings have BIM Models. The project manager shall inform the AA/E if use of Bentley Building Architectural, Electrical, Mechanical, and Structural BIM applications will be required. This requirement shall be specified in the Task Order or Professional Services Contract.

In developing designs, AA/Es may use either MicroStation® or AutoCad®. All AutoCad® work shall be provided in version 2013 or earlier and use only true type fonts (TTF) native to the MS Windows operating system unless otherwise approved by the AOC Technical Support Division. AOC’s drafting, leveling, and symbology standards apply regardless of the authoring software used. Translation and scale conversion from other systems are the responsibility of the AA/E. At commencement of the project, AA/E shall contact the project manager to obtain copies of AOC workspaces, menus, cell libraries, BIM datasets, AOC AutoCad® Requirements, etc.

1.4.2. AOC Provided Information

• Existing Plans: The project manager shall make available to the AA/E the CAD drawings of all areas and disciplines, as they are available within the agency’s master electronic database. The AA/E shall consult with the project manager for availability of documents prior to commencing design. While master plans are believed to be current, the AA/E is responsible for verifying all existing conditions prior to utilizing such masters and the AOC will not be held responsible for omissions or dimensional errors contained therein. All CAD data shall be transmitted in MicroStation .DGN formats only. As available, BIM data shall be furnished.

• CAD Data: The project manager shall provide the AA/E with the following electronic data in MicroStation .DGN format.

o Title Blocks: Use cover sheets and drawing borders (title blocks) as provided by the AOC. Cells/files and user commands to place title blocks shall be provided for 22x34, 24x36, 30x42, and 36x48 sheet sizes. (For projects in which use of other formats is permitted, title block files will be provided with pre-placed title-blocks). Separate title sheet cells shall be provided to support required signature procedures. Final documents shall bear the current Architect of the Capitol’s name.

o Standards: The project manager shall provide a copy of the standard font library, sidebar menus and cell palettes to ease input in conformance with AOC required level/layer schemas, standard architectural/engineering symbology based on Architectural Graphics Standards, and a copy of AOCDEFLT.TBL, the agency’s default color table.

• Workspaces: Use of third-party commercial CAD discipline-specific software is at the consultant’s discretion provided the enclosed layering standards are met and no application-specific elements remain in the file that require use of the application to operate or that could impair standard MicroStation usage, and final translations provide for verified file integrity. The AOC will make available agency workspaces to supplement standard MicroStation usage for the following:

o Architecture: Architectural files may use native MicroStation with AOC Architectural Workspaces or Bentley

Systems' Bentley Architecture file formats.

o Mechanical: Mechanical engineering files shall utilize Bentley Systems' Bentley Building Mechanical with AOC level and symbology defaults or MicroStation with AOC Mechanical workspace.

o Electrical: Electrical engineering files shall utilize AOC Electrical Workspaces with AOC level and symbology defaults or Bentley Systems’ Bentley Building Electrical with AOC levels.

o Structural: Structural engineering files shall use Bentley Systems’ Bentley Building with AOC BIM workspace or

MicroStation with AOC level and symbology defaults.

o Plumbing: Plumbing files shall use AOC Plumbing Workspaces with AOC level and symbology defaults or Bentley

Systems’ Bentley Building Mechanical with AOC BIM workspace.

o Telecommunications: Telecommunication files shall use AOC Telecommunication Workspaces with AOC level and symbology defaults or Bentley Systems’ Bentley Building Electrical with AOC BIM workspace.

o Fire Protection: Fire Protection files shall use AOC Fire Protection Workspaces with AOC level and symbology defaults or Bentley Systems’ Bentley Building Mechanical (piping) and Bentley Systems’ Bentley Building Electrical (controls) with AOC BIM workspace.

1.4.3. Drafting Conventions

• Layer/Level Names: The use of AOC layering conventions is required for all plans. Unless specified otherwise in the

AA/E’s contract, these levels shall be mandatory. The AA/E shall consult the project manager and CAD system manager for clarification or expansion of listing, if required. Level naming standards are contained in APPENDIX B. AOC layer/level names have been derived from the National CAD Standard and CAD Level Standards from the CADD/GIS Technology Center, in Vicksburg, Mississippi. The AA/E shall contact the project manager and CAD system manager to report any conflicts that may arise between the varying standards.

• Line Work: Colors, line weights, and styles shall follow standard architectural practice, and AIA "Architectural Graphics Standards”, Tenth Edition, and APPENDIX B. The AA/E shall restrict actual scaled information line weights to a maximum of three or four weights. Use of standard line types is required; the AA/E shall not utilize "custom line styles" without prior approval.

• Symbols: Symbol names (blocks or cells) shall be standard alphanumeric characters. Cell status shall be maintained in delivered files. The AA/E shall not drop status (or "explode") prior to delivery.

• Text: The AA/E shall use standard Font 1 (Working) for labels and notes. Titles and large-scale text may use AOC Font 5 (Zapf Humanist) or Arial TruType fonts. Minimum text height when plotted for full-size plots shall be 1/10" or 1/8".

These sizes support half-size plotting efforts.

• Annotation: Drawing annotation shall track either AIA MasterSpec "Drawing Coordination Notes" or the recommendations of the CSI. The AA/E shall use system graphics and standard detail libraries and CSI Uniform Drawing System (UDS) system graphic techniques when possible.

• Reference Files: Use of reference files is acceptable; however, it is preferred that path statements are mapped to logical names or directory common to the master file. The AA/E shall consult the project manager prior to finalizing reference file paths on submittal files.

• Working Units: 1:12:8000 (MU:SU:PU) for English or English/Metric architectural files.
