Walsh Construction

Walsh Construction is building two additional data centers on an existing campus in Arizona, each a 48MW tilt-up structure, representing a significant expansion project. The developer or owner has not been publicly identified in the available information. This is a confirmed GC award for Walsh Construction, indicating they have an active and growing data center portfolio in the Arizona market. For sales professionals, this represents a near-term opportunity as the project appears to be in active construction, and the combined 96MW of new capacity signals a major investment. Outreach to Walsh Construction's project team and supply chain should be prioritized given the scale and active status of this build.

Walsh Construction received the NRC 2022 Large Project of the Year Award from the National Railroad Construction and Maintenance Association, which recognizes excellence in railroad construction.

This signal has no relevance for data center industry business development purposes. No action is warranted based on this information.

Walsh Construction is building a new data center campus on a 242-acre greenfield site in Wisconsin, referred to as 'Wisconsin Data Center Campus Site 2.' The project includes three primary structures featuring a two-story conventional steel framed building, indicating a significant-scale development. The developer or client has not been publicly identified in the available information. This confirmed GC award for Walsh Construction on a large greenfield campus signals substantial new data center capacity coming to the Wisconsin market, presenting opportunities for suppliers and subcontractors involved in critical power, cooling, and infrastructure. Given that this is a greenfield campus build with multiple structures, procurement and vendor selection are likely actively underway, making timely outreach important.

Walsh Construction completed a 140,000-square-foot data center expansion for an unnamed communications firm, bringing the facility's overall whitespace capacity to 50,000 square feet. The project is an expansion of an existing data center, and Walsh Construction served as the general contractor. The specific city and state are not disclosed in the available information, and the client is identified only as a 'communications firm.' This confirmed GC award demonstrates Walsh Construction's capability in data center expansion projects for telecommunications and communications companies. For BD professionals, Walsh's involvement signals their active presence in the data center construction market, and tracking this communications firm client could reveal future expansion phases or additional facility investments.

Archer Western Construction, a subsidiary of Walsh Construction, has been awarded a preconstruction services contract for the Central Arizona Project (CAP) Aqueduct Hydrology Improvement CMAR Project in Arizona. The client is the Central Arizona Project, a major water infrastructure entity. This is a hydrology improvement project delivered via Construction Manager at Risk (CMAR) and is not a data center project. While the award confirms Walsh/Archer Western's active presence in Arizona infrastructure, this particular project does not directly signal data center construction activity. Sales professionals should note Walsh's expanding footprint in Arizona but should not treat this as a data center opportunity.

Walsh Construction completed a 95,000-square-foot data computing and training center for Healthcare Services Corporation (HCSC), a major health insurance company. The single-story facility serves as HCSC's primary data processing center and includes training functions. Walsh Construction was the general contractor on this project, indicating a confirmed GC award for a purpose-built enterprise data center. For data center sales professionals, this signals HCSC as an active enterprise buyer of data center infrastructure and Walsh as an experienced GC in this space. The project appears to be completed, so any immediate sales opportunities would relate to ongoing operations, upgrades, or potential expansion of the facility.

Walsh Construction has been awarded the general contractor role for the SSC Enterprise Data Centre in Borden, Ontario, developed by Defense Construction Canada with Ehvert Mission Critical serving as architect. The contract value is listed as confidential, and the project appears to be a new construction data center supporting the Shared Services Canada (SSC) enterprise infrastructure. This is a confirmed GC award for a government-backed defense data center project in Ontario, Canada, indicating Walsh Construction's involvement in mission-critical federal facilities. For data center industry sales professionals, this represents a significant opportunity to engage early on infrastructure, power, cooling, and security solutions for a government-grade facility. The project is active and likely in early construction phases, making timely outreach important.

Walsh Construction served as GC for a 53-acre data center campus in Hoffman Estates, IL (not Chicago proper), delivering two data centers with 38.4 MW of critical IT power. Each building includes admin space and multiple COLO data halls with 2N redundant power (UPS/PDU), evaporative AHU cooling with hot aisle containment, and pre-action fire protection. The site includes a new substation with four 40 MW transformers (160 MVA total capacity) and redundant generator power with integral belly fuel tanks. Owner and architect are listed as confidential.

Walsh Construction is building a data center campus on a 315-acre greenfield site in Mount Pleasant, WI, for a confidential owner. The project includes three primary structures: a two-story steel-framed building with 294.4 MW critical IT load, a one-story building with 43.2 MW critical IT load, and a Central Utility Plant with non-evaporative water-cooled chillers. Walsh provided preconstruction services and OFCI management overseeing approximately 5,000 pieces of commissionable equipment. The project is described as a first-of-its-kind AI facility requiring agile delivery strategies.

Walsh Construction completed a 361,000-square-foot data center addition for an undisclosed financial firm, which included upgrades to existing infrastructure to achieve a Tier 3-plus performance classification. The project is classified as an expansion, combining new construction with infrastructure upgrades to the existing facility. The specific client, city, and state are not disclosed in the available information, though the project is confirmed as part of Walsh Construction's portfolio. For data center industry sales professionals, this signals Walsh Construction's proven capability in delivering large-scale, high-tier financial sector data center projects, making them a key GC to monitor for future opportunities. Given that this project appears to be completed, the immediate BD urgency is low, but tracking Walsh for similar upcoming financial sector data center work is recommended.
