Air Force B-21 Facility Cost Estimating Support 

Under MSI’s USACE Walla Walla Cost Engineering contract, MOCA Services provided parametric cost estimating support to the USACE Kansas City District and the U.S. Air Force Planning Assistance Team for new B-21 military construction facilities at three major Air Force installations. 

As part of this critical federal program support, MOCA Services embedded a senior cost estimator to develop preliminary cost estimates for mission-critical infrastructure, drawing on conceptual design documentation, planning criteria, and reference materials provided by the client. Estimates were developed using the latest PACES software in accordance with USACE standards and procedures. 

MOCA Services also deployed a discipline-specific team—including architectural, structural, civil, mechanical/electrical, and risk analysis experts—to review the MCACES Second Generation (MII) current working estimate. 

The primary goal was to produce accurate early-phase cost forecasts to support funding requests, strategic programming, and long-range infrastructure planning for the B-21 Raider program. 

Project Overview 

This project supported the development of more than 2.4 million square feet of new B-21 infrastructure across three strategic Air Force installations. The facilities varied in complexity and function, supporting mission-critical needs such as aircraft maintenance, training, and operations planning. MOCA Services provided estimates for: 

  • 38 projects at Ellsworth AFB (SD), totaling over 1.46 million square feet 
  • 8 projects at Whiteman AFB (MO), covering more than 385,000 square feet 
  • 10 projects at Dyess AFB (TX), encompassing over 590,000 square feet 

Each estimate played a critical role in shaping early funding strategies and guiding long-range facility development aligned with U.S. Air Force operational goals.
