The Modal Shop, Inc.

The Modal Shop, Inc., doing business as TMS, a subsidiary of PCB Piezotronics, Inc., manufactures and supplies vibration sensing and calibration equipment to federal defense and aerospace agencies as a prime contractor (94% of recent awards), with no set-aside designations across its footprint. TMS is a for-profit manufacturer headquartered in Cincinnati, Ohio, with performance occurring primarily at its Wyoming, Ohio facility. The vendor competes full-and-open and has not pursued socioeconomic set-asides in recent procurement activity.

TMS's capability portfolio centers on specialized calibration systems and vibration measurement instrumentation. The company's product line includes secondary vibration calibration systems (used to calibrate piezoelectric accelerometers, high and low impedance transducers, and velocity sensors), portable vibration calibrators, accelerometer calibration workstations, and primary vibration calibration systems. Representative prime work includes a $1,064,000 delivery order from Naval Sea Systems Command in July 2023 for a secondary vibration calibration system, a $982,710 delivery order from the same command in January 2022 for a portable vibration calibrator, a $410,440 delivery order in May 2022 for three secondary vibration calibration systems, and a $329,389 purchase order from Naval Sea Systems Command in April 2024 for a primary vibration calibration system. More recently, TMS delivered a $798,000 secondary vibration calibration systems order to Naval Sea Systems Command in May 2025 and a $25,037 two-year secondary service contract for calibration systems to NASA's Shared Services Center in April 2026, covering secondary calibrations, software upgrades, annual training, and service visits for the 9155D system.

Customer concentration is pronounced. Naval Sea Systems Command dominates both award count and dollar value — 44 awards worth $11 million combined potential value represent 47% of the award count and 59% of total potential value across TMS's footprint. The top five customers account for 47% of awards and 84% of combined potential value, with the Department of the Air Force Materiel Command placing seven awards for $2.7 million, the Army Materiel Command's Aviation and Missile Life Cycle Management Command placing sixteen awards for $999 thousand, the Army Test and Evaluation Command placing twelve awards for $552 thousand, and NASA's Shared Services Center placing fourteen awards for $365 thousand. The portfolio spans 50 distinct federal agencies, but concentration in Navy calibration requirements is the defining characteristic.

TMS holds three significant Indefinite Delivery Contracts with Naval Sea Systems Command. The largest, awarded May 18, 2022, is a $3.6 million IDC running through May 11, 2027, for secondary vibration calibration systems; task orders against this vehicle have ranged from $266,000 to $1,064,000. Two additional IDCs for portable vibration calibrators are valued at $2.02 million (awarded December 2020) and referenced in multiple contract summaries as active vehicles generating task orders. Beyond Navy IDCs, TMS places work under the Federal Supply Schedule (GSA) with 43 task orders worth $1.1 million combined potential value, and holds or participates in additional Air Force and unspecified IDCs that account for lower order volumes.

Activity has grown from a baseline of nine awards in 2022 to twenty-three in 2024, though 2025 and early 2026 have produced only eight awards year-to-date, reflecting the seasonal and requirement-driven nature of calibration equipment procurement. Five awards with ultimate completion dates in the next twenty-four months carry combined potential value of $303 thousand, representing modest recompete exposure in that window. The vendor's combined potential value across 201 total awards stands at $18.6 million, with $13.4 million obligated (72% of potential value), indicating a mature, established position with realized revenue backing the pipeline.

In its subcontractor role, TMS supplies vibration and accelerometer measurement equipment to defense primes including Lockheed Martin (guided missile components and electrodynamic exciter kits), Northrop Grumman Systems Corporation (ship repair leases and rentals), L3Harris Technologies (accelerometer cables and accelerometers for the Wide Field Infrared Survey Telescope Optical Telescope Assembly), Fluor Marine Propulsion (Naval Nuclear Laboratory equipment including resonance ultrasound spectroscopy equipment and high-range microphone comparison calibrators), and BAE Systems (instrumentation range support program equipment). Sub work represents 6% of the award base by count and appears to flow through defense prime integrators on major platforms rather than through specialized IT or systems primes.

TMS's primary NAICS concentration is Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals (55 awards), followed by Other Electronic Component Manufacturing (34 awards) and Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables (34 awards). The PSC footprint aligns: Electrical and Electronic Properties Measuring and Testing Instruments (54 awards) and Laboratory Equipment and Supplies (21 awards) dominate. The company's capital-intensive, specialized product portfolio — systems that retail for $16,000 to over $1 million per unit — drives a delivery-order and purchase-order model under Navy IDCs rather than BPAs or task-order vehicles with high velocity.

As a subsidiary of PCB Piezotronics, TMS inherits parent-company connectivity to the broader sensing and transducer supply ecosystem serving defense test, evaluation, and certification programs. PCB Piezotronics itself holds contracts with federal agencies, but TMS operates with distinct UEI and contract award identity, suggesting operational autonomy within the parent structure.
