CACI International opened a 61,000-square-foot Manufacturing Center of Excellence for Defense Electronics at 3750 Monroe Ave. in Pittsford on Aug. 18, 2026, a build-out that increases the company's Rochester-area manufacturing footprint by more than 300 percent (Rochester Business Journal). The company confirmed the opening and the scale of the expansion in its own announcement (CACI International, via Yahoo Finance).

The facility is production space for signals-intelligence and electronic warfare hardware, and it lands in a market that has been rebuilding its manufacturing base around optics, photonics and defense electronics rather than volume assembly.

What Happened

The new center supports production of the U.S. Army's Terrestrial Layer System Brigade Combat Team (TLS BCT) Manpack, a soldier-carried electronic warfare and signals intelligence system (Rochester Business Journal). CACI received a contract modification valued at nearly $400 million in 2025 tied to that program (CACI International).

The Rochester presence traces to CACI's $225 million acquisition of Mastodon Design LLC in 2019, a ruggedized-electronics firm based at 55 Science Parkway in Rochester (Rochester Business Journal). The Pittsford building consolidates and expands that capability, and CACI said the site has room for further expansion (CACI International).

Monroe County Executive Adam Bello and U.S. Rep. Joe Morelle attended the opening (Rochester Business Journal).

Key Project and Company Details

• Address: 3750 Monroe Ave., Pittsford, New York (Rochester Business Journal)
• Size: 61,000 square feet; more than a 300 percent increase in manufacturing space (CACI International)
• Opened: Aug. 18, 2026 (Rochester Business Journal)
• Program: U.S. Army TLS BCT Manpack, backed by a nearly $400 million 2025 contract modification (CACI International)
• Company scale: CACI reported fiscal 2026 revenue of nearly $9.7 billion and approximately 27,000 employees (CACI International)
• Supply chain: The operation supports dozens of Upstate New York small-business suppliers (CACI International)

One caution for anyone benchmarking costs: CACI has not published a construction cost, general contractor, or design team for the Pittsford facility, and none of the available reporting identifies them (Rochester Business Journal; CACI International). Treat any circulating dollar-per-square-foot figure for this project as unverified.

Executive Comments

CACI President and Chief Executive Officer John Mengucci spoke at the opening, as did Executive Vice President of Electronic Warfare Tom Kirkland, who said demand for advanced electronic warfare technology is surging (CACI International). Chris Monoski, the company's executive vice president for manufacturing and a Rochester Institute of Technology graduate, also participated (Rochester Business Journal). Defense trade coverage framed the facility as a capacity response to accelerating electronic warfare requirements (The Defense Post).

Why It Matters to Construction Professionals

Defense electronics production space is a specific building type, and it behaves differently from the light industrial and warehouse work that has dominated suburban Monroe County absorption. Expect requirements around electrostatic discharge control, controlled temperature and humidity, shielded or restricted areas, secure access control, and clean assembly zones. Those requirements push construction value into electrical, mechanical, low-voltage and finishes scopes rather than into structure and site work.

Second, this is an existing-building expansion story, not a greenfield one. The company describes a more-than-300-percent increase in manufacturing space with room to grow further (CACI International). For contractors, that means the near-term opportunity set is interior build-out, process utility upgrades and phased expansion inside a secured envelope — work that rewards firms comfortable with badging, escorting and background-check requirements.

Third, program funding drives schedule. The nearly $400 million contract modification in 2025 preceded the facility opening in 2026 (CACI International). Defense construction demand in this region is therefore readable in advance from award announcements, which gives contractors a genuine forecasting tool.

Implications for Owners, Developers, Contractors and Subcontractors

For owners and developers, the Pittsford project is evidence that Monroe County can retain and grow high-value manufacturing tenants in existing suburban corridors. Buildings on Monroe Avenue were not designed as defense plants; converting them requires power capacity, structural capacity for equipment, and dock and staging improvements. Developers holding older suburban office and flex assets should be evaluating whether their properties can meet those thresholds.

For general contractors, the recurring theme in this market is cleared, credentialed capability. Firms that already work at Mastodon's Science Parkway site, or on other defense and aerospace campuses in the region, have a structural advantage in follow-on packages.

For subcontractors, the addressable scopes are concentrated: switchgear and distribution, UPS and backup power, precision HVAC, grounding and shielding, access control and intrusion detection, epoxy and static-dissipative flooring, and specialized casework or benching. Local suppliers should also note CACI's statement that the operation supports dozens of Upstate New York small businesses (CACI International).

What to Watch Next

The clearest signal to monitor is future Army production and follow-on orders for TLS BCT Manpack. Because CACI has stated the Pittsford site has room for expansion, additional program awards would plausibly translate into another build-out package rather than a new site search (CACI International).

Also watch whether the 55 Science Parkway operation is repurposed, expanded or consolidated, and whether local incentive filings appear for any further Pittsford phases. County-level industrial development agency agendas are the practical place to catch those early. And keep an eye on regional workforce programs: precision electronics assembly competes for technicians with the same optics and photonics employers already active in Rochester (Rochester Business Journal).

Bottom Line

CACI's 61,000-square-foot Pittsford facility, opened Aug. 18, 2026, more than quadruples the company's local manufacturing space and is tied to a nearly $400 million Army electronic warfare award (CACI International). Cost and construction-team details have not been disclosed, so the useful signal for contractors is not the price tag — it is the confirmation that defense electronics is now a repeat source of high-specification interior construction demand in Monroe County.
