DBB 3.0 Design Development (DD)

3.1 Prepare Design Development (DD) Documents

Based on the Final Schematic Design (SD) Documents and the Response Memorandum to the Investment Review Board (IRB) review questions, prepare the following:

The Architect/Engineer (A/E) shall exclude Brand Name materials from specifications and utilize salient characteristics to the maximum extent practicable. When Brand Name is required to ensure quality of design, and the A/E suspects [based on market research] that suitable equal materials are likely available from other manufactures, the A/E shall identify the item as “Brand Name or Equal,” and include the salient physical, functional, or performance characteristics that will satisfy the design requirements in the specifications in the following format:

[Brand Name; Part Number; Etc.] Brand Name or Equal Salient Characteristics that an equal must meet are delineated below:

Physical: (All physical characteristic that an equal must meet shall be included here).

Functional: (All functional characteristic that an equal must meet shall be included here).

Performance: (All functional characteristic that an equal must meet shall be included here).

If any of the above mentioned characteristic categories (physical, functional, or performance) are not applicable, “None” shall be used to denote that no salient characteristics apply to that specific brand name or equal description.

3.2 Develop In-Depth NPS Constructability Checklist (DD Comments)

Identify unique project issues under the DD Comments (Design Development) column on the NPS Constructability Checklist. A Constructability Analysis utilizing the NPS Constructability Checklist is required for every project.

Template: NPS Constructability Checklist


3.3 Draft Contract Price Schedule

Prepare a draft Contract Price Schedule utilizing the Contract Price Schedule template.

Template: Contract Price Schedule

Sample: second tab of Contract Price Schedule template

Guideline: Guide for Specifiers (pdf)


3.4 Update Class B MasterFormat Construction Cost Estimate and Construction Schedule

Update the Class B MasterFormat Construction Cost Estimate based on the completed Design Development (DD) documents. Confirm that project cost is within available funds.

Template: Class B & A MasterFormat Construction Cost Estimate

Guidance: Cost Estimating Requirements Handbook


3.5 Conduct Value Methodology (VM)

If required, conduct a Value Methodology Exercise when draft design and contract documentation is approximately 30%-50% complete. Identify major asset/components/systems and proposed changes for reasons of performance, reliability, quality, and value. Provide recommendations to modify the design based on value methodology principles.

While not required for projects under $10 Million, value methodology exercises may be effectively used on an overall project bases for selected systems and/or decisions.

Prepare Value Methodology Report. Final submission will be made with the Schematic submission to the Investment Review Board (IRB).

VM Tools (templates and standards):

  • Value Methodology Report template and other VM Tools are available through NPS Project Managers (PMs).

Guidance: Director's Order (DO) 90 Value Analysis


3.6 Permitting

If permitting was completed in Predesign and Schematic Design following the DSC PPMP, continue to 3.6.2 Initiate Permit Acquisition Services.

If permitting was not completed in Predesign and Schematic Design following the DSC PPMP, complete Late Permit Scoping (3.6.1.1, 3.6.1.2, & 3.6.1.3). As soon as available, provide Late Permit Scoping deliverables: Permitting Assessment Form (PAF), Permitting Road Map, and Permit Plans.

3.6.1 Late Permit Scoping (if required)

Select Permitting Lead

The Architect-Engineer (A/E) is responsible for leading the DSC Project Permitting Management Process (PPMP). Provide name and qualifications of A/E staff member for approval to act as the Permitting Lead.

3.6.1.1 Permit Scoping & Permitting Assessment

Initiate Permit Scoping & Prepare Permitting Assessment Form (PAF)

Evaluate potential jurisdictions and Agencies that apply to the project. Identify applicable project topics, missing information, and decisions needed to determine applicable permits. Use this information and any information provided by National Park Service to identify permits. If information is insufficient to identify permits, inform National Park Service and include necessary steps to obtain needed information.

Research missing information and questions in the PAF. As the design develops, review for compliance with applicable regulations and applicable permits. Document resolutions to issues, identify additional concerns, and identify permits.

Form: Permitting Assessment

Finalize Permit Scoping & PAF

Finalize jurisdictions and Agencies that apply to the project. Refer to the PAF and finalize project topics. Resolve missing information or decisions needed to determine applicable permits.

Form: Permitting Assessment

3.6.1.2 Prepare Permitting Road Map

Provide a list of all appropriate permits and their needed associated milestones by stage. Recommend if permits should be:

Form: Permitting Road Map

3.6.1.3 Initiate Permit Planning & Prepare Permit Plans

Conduct Permit Planning Meeting

Review draft Permitting Asssessment Form (PAF) and draft Permitting Road Map.

Minimum attendees:

Goals:

Prepare Permit Plans

Working collaboratively with the interdisciplinary team (IDT), at a minimum, prepare a Permit Plan for each Design (Government-Furnished (GF)) Permit.

Form: Permit Plan

3.6.2 Initiate Permit Acquisition Services (if required)

Initiate Permit Acquisition Services (3.6.2.1, 3.6.2.2, & 3.6.2.3) if during permit scoping, Design (Government-Furnished (GF)) Permits were reliant on the Design were identified. Design (GF) Permits are part of design responsibility.

3.6.2.1 Prepare Permit Schedule

Review Permitting Road map to be used in Division 1 Specifications 01 31 00 Project Management and Coordination. Prepare a Permit Schedule using the timelines developed in the Permit Plans.

3.6.2.2 Develop Application for each Design (Government-Furnished (GF)) Permit

Develop an application for each Design (GF) Permit on the Permitting Road Map and include all required documents and products. Consult with the appropriate Agency for each permit. Bring any permit issues to the interdisciplinary team (IDT) for resolutions. Provide a draft application for each Design (GF) Permit to the IDT for review prior to submitting to the associated Agency. Finalize the application by incorporating comments from the IDT review.

3.6.2.3 Initiate Permit Acquisition and Provide Permit Status and/or Final Permits

Obtain all Design (GF) Permits identified in the Permit Plans. Submit Design (GF) Permit applications and proactively manage the DSC Project PPMP to ensure each permit is issued within the identified timeline. Consult with the interdisciplinary team (IDT) to prepare and submit additional documents requested by the Agency and resolve any comments. Provide original versions of all issued permits to NPS by the required date.


3.7 Complete Construction Inspection Checklist (Phase 1 projects only)

Based on the design and the International Code Council (ICC) Codes and National Fire Protection Association (NFPA) 70, indicate which inspection will be required during construction. This does not include Special Inspections. Checklist will be reviewed by the appropriate Building Code Official.
