As one of the oldest and most respected general contractors in America, McCarthy Building Companies brings more than 160 years of building experience to every project — underpinned by a commitment to innovation, technology, and integrated delivery. The company’s self-perform model — which enables McCarthy to directly execute scopes including concrete, electrical, mechanical, plumbing, drywall and framing — is foundational to its approach. In recent years, McCarthy has publicly emphasized that prefabrication and offsite modular construction are not just supplemental tactics but central to the firm’s long-term strategy as labor shortages, supply-chain disruptions and cost inflation reshape the construction industry. For example, on the 40,500-square-foot outpatient clinic for CHI Health in Omaha, McCarthy reported prefabricating over 75% of the exterior walls and more than 60 % of the building enclosure, yielding schedule and cost advantages. 

Recognizing that self-perform prefab offers a compelling path forward – combining operational control, quality assurance and delivery speed – McCarthy determined that implementing a robust manufacturing execution platform was essential to fully capturing the ROI of offsite construction. That’s where Offsight comes into play. Designed with Design for Manufacturing & Assembly (DfMA) workflows in mind, Offsight offers a real-time, shop-floor-centric solution for project manufacturing rather than a retrofit of field construction software. McCarthy selected to partner with Offsight, to enable the firm to capture key production metrics, for example takt time, scrap rate and cycle time, that conventional field tools simply don’t support. By using Offsight as a single system of record for production, labor and materials workflows, McCarthy is positioning itself to deliver faster, more cost-efficient and higher-quality outcomes from its self-perform prefab business.
