The government requires an Architect and Engineering firm to update the existing plans and specifications for a security forces center renovation to meet current codes. The original design was completed in October 2021. Only the original A&E firm can legally certify the drawings without a full redesign, and it holds the native BIM files and engineering data. A new firm would face significant ramp-up time and duplicate effort, forcing the government to pay for recreating baseline calculations and load models. This requirement is best fulfilled by the original firm to avoid redundant costs.
