Task Mission Remove Radomes at selected sites without compromising Upper air Inflation Building (UAIB) integrity Review PWS Highlights & Deliverables Overview of UAIB’s & Radomes Types & Settings / Radome Details / Roof Conditions / On-site Constraints / Map Proposal Instructions Address Questions Tour of Radome (On-site Attendees) Adjourn

Agenda

NWS intends to remove (Government) selected radomes given the constraints of building conditions Radome candidates for removal will be selected under the assumption that:

UAIBs are structurally sound UAIBs will not require any significant structural changes/repairs to make the building safe for use after the radome is removed Major structural changes, repairs, or modifications as a result of Radome removal are considered beyond the scope of this contract.

Task Mission

Review PWS & Deliverables Task Area 1: Assessment (Site Visit) Submit plans to remove the radome and any required refurbishment of the UAIB roof.

Submit plans to dispose of the radome and related construction materials.

Submit a detailed cost estimate to execute radome removal, disposal.

Task Area 2: Radome Removal Remove the radome and associated materials.

Repair/refurbish the roof on UAIB and cover it with a long lasting, durable waterproof membrane.

Dispose of the old radome and related materials in an environmentally responsible manner.

Deliver site-specific Final Report with associated documentation.

Objectives:

Site-Specific Planning Package must include:

Appendix C: Radome Removal Plan Appendix D: Radome and Structural Materials Disposal Plan Appendix E: Roof Repair/Refurbishment Radome Removal Design Plan Appendix F: Hazardous Materials Removal/Mitigation Plan, if needed Appendix G: Accident Prevention Plan

Review PWS & Deliverables (cont.)

Review PWS & Deliverables (cont.)

Site-Specific Cost Estimate to include:

Project Planning: Engineering design and planning Mobilization and Equipment Staging: Travel to the site and set up the equipment Radome Removal & Disposal: Remove the radome and any electrical conduits UAIB Roof Surface Preparation: Refurbish roof structure as needed and prep the roof deck for waterproofing UAIB Roof Membrane Installation: Install a new waterproof roofing membrane, and any needed caulking/flashing Site Clean Up and Inspection: Cleanup and return building to operational status Project Wrap Up and Reports: Engineering follow up and report preparation in the weeks after construction

Review PWS & Deliverables (cont.)

Site-Specific Radome Removal Reports to include:

Summary of the removal activity from start to finish; highlighting key steps and any problems encountered Description of any deviations from the radome removal plan Description of how and where all radome components, construction materials, and hazardous materials were disposed Before and after photographs of the UAIB roof (pre- & post-removal) Final ‘as-built’ drawings that reflect modifications (specified in the PWS) Description of areas of concerns related to the UAIB’s structure or physical condition Any lessons learned (best practices) at this site that may be applicable for future radome removal activities

General Task Deliverables

Task 1 & 2 Deliverables

Types & Settings:

Diverse Scenarios: UAIB’s vary in age, condition, and construction material.

UAIB’s are located at sites throughout CONUS with unique layouts and varying degrees of access.

UAIB & Radome Overview

Site: Jackson, MS UAIB: Corrugated Steel Site: Springfield, MO UAIB: Cinder Block Site: Salem, OR UAIB: Masonry/Stucco Site: Greensboro, NC UAIB: Brick & Mortar Radomes are typically made of fiberglass sections bolted together and to the UAIB roof.

Site: Dallas/FW, TX UAIB: Cinder Block

Site: Grand Junction, CO

Radome Details (Exterior):

The quality of roofing at each UAIB will vary from site to site.

The Pittsburgh site illustrates the typical membrane barrier on UAIB roof surrounding each Radome.

UAIB Roof Conditions

Site: Pittsburgh, PA

Site: Pittsburgh, PA Typical UAIB Site Layout An example of UAIB roof materials and conditions around each Radome.

Radome

Some UAIB’s have existing equipment on their roof requiring attention to work around.

Greensboro illustrates an antenna array that rests upon the roof near the Radome.

Any roofing activity will need to address repositioning existing assets.

NWS will alert the vendor to sites with similar constraints.

On-Site Constraints

Site: Greensboro, NC UAIB: Brick & Mortar Examples of MROS on UAIB roof that must be worked around during roof rehab.

Proposal Instructions Proposal Due: July 21, 2023 at 12:00 PM EDT Submit to: Nicole Frie, Nicole.Frie@noaa.gov Proposal Volume Format:

Volume I: Business Proposal Volume II: Technical Proposal Volume III: Past Performance Volume IV: Price

Factor 2 Past Performance

Factor 3 Price Unlimited

Factor 1 – Technical Approach Planned approach to performing this work Type of equipment to be used Labor categories Qualifications for both CLIN 0001 Site Assessment and CLIN 0002 Dome Removal and Roof Remediation Crew accommodations, major subcontractors and their roles, and anticipated schedule of work.

Factor 1 – Technical Approach (Continued) The planned approach shall include:

Health and safety plan Quality assurance plan Quality control inspection system

Factor 2 – Past Performance Describe relevant performance on other contracts or affirmatively state that it possesses no relevant past performance.

List up to, but not more than three (3) contracts similar in size, scope, and complexity as that of the PWS, utilizing Attachment III – Past Performance Information Form. Each past performance reference is to be listed separately.

Evaluation Factors Factor 3 – Price:

Price proposals should support the proposed technical factor and will be evaluated for reasonableness of (1) Total Evaluated Price (TEP), (2) completeness and (3) unbalanced pricing. Offerors whose price is determined to be incomplete or unreasonable will not be considered for award.
