Quick Summary

The National Aeronautics and Space Administration (NASA) Kennedy Space Center has issued a Justification for an Exception to Fair Opportunity for the design modification of the Vehicle Assembly Building (VAB) High Bay 3 (HB-3) for the Space Launch System (SLS) Phase 3. This justification supports a sole-source award to Merrick & Company under the Southeast Regional Architect and Engineer (SERAE) contract.

Purpose of Justification

This document justifies issuing a firm-fixed-price task order to Merrick & Company without full and open competition. The basis for this exception is FAR 16.505(b)(2)(i)(C), citing that it is a logical follow-on to an order already issued under the contract, and is in the interest of economy and efficiency.

Scope of Work

The requirement is for the study and design modification of the VAB High Bay 3 (HB-3) at Kennedy Space Center, Florida, to support the Space Launch System (SLS) Block 1B Crew, Phase 3. This includes designing specialized platforms to be installed, which are a key component of the overall construction work. Merrick is also involved in evaluating integrated models for existing level B2 and C platforms.

Contract Details

  • Contract Type: Firm-Fixed-Price Task Order
  • Parent Contract: Southeast Regional Architect and Engineer (SERAE) contract 80KSC022DA115
  • Awardee: Merrick & Company
  • Period of Performance: Estimated 245 days from award
  • Product/Service Code: C219 (Other Architect And Engineering Services)
  • Place of Performance: Kennedy Space Center, Florida

Basis for Exception

Merrick & Company is identified as the only Architect and Engineer (A&E) firm with the specialized expertise required to design the platforms and is the Engineer of Record (EOR) for the design. Procuring this design from another contractor would likely result in significant additional costs and schedule delays due to the need for extensive familiarization with the ongoing work and existing designs.

Additional Notes

This is a justification notice, not a solicitation for proposals. The Contracting Officer will continue to examine the market for alternative solutions for future acquisitions.
