Standards & Criteria Design Standards Manual Purpose of this Document

Purpose of Design Standards Manuals The DEN Design Standards have been developed to ensure a unified and consistent approach to the thematic and technical design for DEN. These standards are for use and strict implementation by all consultants under contract to DEN, to tenants, and all other consultants under contract to any other entity for the design of projects at DEN.

The Standards Manuals are working documents, which will be revised and updated, as required, to address the general, conceptual, design, and technical standards for all areas of design for DEN.

This Design Standards Manuals (DSM) for DEN has been prepared for use by competent, professionally licensed architectural and engineering consultants under the direction of DEN Maintenance and Engineering or tenants of

DEN.

The Design Standards shall not be quoted, copied, or referenced in any bidding or construction contract doc-uments. Content contained in this Manual shall not be copied in any bidding or construction documents, except where specifically instructed to do so. All information contained in these standards must be fully explained and shown in all bidding and contract documents.

The Design Standards Manuals are intended to be used as a whole, as each manual is complimentary to the other DSMs. To understand the overall thematic and design standards for DEN, the applicable manuals must be utilized together and not separated from the Design Standards Manuals.

The Consultant shall not reproduce, duplicate in any manner, transmit to other consultants or other entities, or use in conjunction with other projects without the express written consent of DEN.

NOTE: This document is optimized for duplex (double-sided) printing.

VARIANCE FROM DEN DESIGN STANDARDS MANUALS

Requests for non-conformance or variance from DEN Design Standards manuals, for any DEN or Tenant Projects, must be formally submitted using the online DSM Variance Request form at the following website:

DEN DSM Variance Request Form

Variance requests may or may not be approved by DEN and response will be communicated to the requestor.

Standards & Criteria Design Standards Manual Chapter 1-Administration

Chapter 1 - Administration

1.0 Administration

1.0.1 References

The DEN Design Standards may be cited as such and are referred to herein as the Standards. The Design Standards Manuals are referred herein as DSMs.

City and County of Denver is referred to herein as the City or CCD.

Denver International Airport is referred to herein as DEN.

DEN is operated by the Department of Aviation of the City and County of Denver. More information about the organization and administration of DEN can be found at:

Denver International Airport

Denver Government Website

1.0.2 Purpose

The DSMs define a precise architectural and engineering vocabulary that serves as a basis for making decisions throughout the design and construction process. The DSMs provide direction without limiting the creative abilities of those who are governed by them.

1.0.3 Scope

The provisions of the DSMs apply to the design of any building, structure, infrastructure, or improvement on DEN property.

1.0.4 Format

Where specific formats are provided or referenced, those formats shall be used by the consultant.

1.0.5 Procedures

The procedural guidelines contained in these manuals are intended to supplement existing consultants’ pro-cedures and to establish a uniform basis for program control for DEN. Where the manuals are silent on a pro-cedural matter, it is incumbent on the consultant to request specific direction from the DEN Project Manager. If no guideline is available, the consultant shall propose its existing corporate guidelines.

1.0.6 Exclusions

The DSMs are not all-inclusive, and there are areas of the DSMs that do not address design requirements. In these instances, the consultant shall use professional design judgment and expertise in preparing a proposed system design for those areas within the consultant's Scope of Work (SOW).

1.0.7 ORAT Requirements

The Operational Readiness, Activation, and Transition (ORAT) team at DEN plays a critical role in ensuring that DEN’s Design Standards Manuals integrate operational requirements throughout the design and construction phases. By collaborating closely with project teams, architects, and engineers, ORAT ensures that the DSMs align with the airport’s functional and operational needs. This alignment is achieved by gathering feedback based on operational expertise, identifying potential challenges in facility layouts, and ensuring that the final design

Q4 2024 29 Denver International Airport https://www.flydenver.com/ https://denvergov.org/Home facilitates a seamless transition to full-scale operations. Program and project design teams are expected to be familiar with the DEN ORAT Standards Manual (OSM) and actively participate in ORAT-led meetings, charrettes, workshops, trials, and testing at the request of the DEN Project Manager.

1.1 Compliance with Codes and Regulations

The DSMs are not to be used in lieu of codes or regulations that may be applicable to design or construction work.

The user of the DSMs shall be solely responsible for the design product compliance with all codes and regulations.

In some cases, the DSMs contain requirements that are more stringent than codes or regulations. The user shall comply with the more stringent requirement unless the requirement conflicts with any code requirements.

1.2 Variance and Interpretation

It is recognized that these DSMs may not always contain the newest developments in technology. While airport construction is not to serve as an experiment for new, untested systems and technologies, the consultant should present to DEN any proven new developments in systems and alternate methods of technology which the con-sultant thinks are worthy and beneficial for consideration.

1.2.1 Request Submittals

Variance and interpretation requests must meet at least one of the following criteria:

A. Improvement to design B. Improvement to public safety C. Improvement to construction schedule D. Construction cost savings E. Operation and maintenance cost savings F. Resolution of conflict of established standards G. Design condition not covered by the DSMs H. Lifecycle cost-benefit

Consultant shall submit the appropriate form to the Project Manager for approval. Consultant shall not proceed with any variance in design without written approval from DEN.

1.2.2 Request Format

Variance requests shall be submitted for stakeholder review using the DSM Variance Request form accessible from the link below

DEN DSM Variance Request Form

Approved DSM variances shall be submitted to DEN using the RFI process in Unifier, the current DEN Project Man-agement Information Systems (PMIS). Requests shall include evidence of the stakeholder approval, such as an email record and shall contain the following information:

A. Project title and description B. Applicable Design Standards by reference to manual, volume, part or chapter, section, subsection, and exhibit.

C. Description of requested variance, including any applicable drawings and calculations to fully develop variance in question.

D. Budget impact of proposed variance E. Schedule impact of proposed variance F. Other pertinent factors
