The St. Louis Board of Aldermen deferred a vote on new citywide zoning rules governing data center development after public pushback. The proposed regulations would establish a comprehensive framework for data center siting across St. Louis, not a single project. Community concerns—likely noise, water, and energy impacts—drove the delay. No specific developer or capacity figures are tied to the rules. GCs and suppliers targeting St. Louis should monitor the rescheduled vote, as final rules will dictate permitting requirements for all future builds in the market.

A St. Louis-based investor is seeking a conditional use permit to convert the Armory building into a data center in St. Louis, Missouri. This is a retrofit project that is still in the permitting and approval stage, with no confirmed general contractor, project size, or contract value disclosed at this time. The project represents an adaptive reuse approach to data center development in the St. Louis metro market, which could signal growing interest in the region for data center capacity. For BD professionals, this is an early-stage opportunity where construction services, MEP systems, and data center infrastructure vendors could potentially engage before contractor selections are finalized. Urgency is moderate — the conditional use permit process suggests the project is still in its early planning phases, leaving time for outreach.

A local real estate investor has filed documents with the city of St. Louis to convert a shuttered historic Armory building into a data center, with the project valued at approximately $3.1 billion. The developer has not been fully identified in available reporting, and no general contractor has been named at this stage. The project is located in the St. Louis, MO metro area and appears to be in the early planning and permitting phase. A $3.1 billion data center retrofit of this scale would represent a significant investment in a market not traditionally known as a major data center hub, potentially signaling growing demand for capacity in secondary markets. Given the early-stage filing status and lack of confirmed partners, this is worth monitoring closely but outreach should begin soon to establish relationships before contractor selections are finalized.

TierPoint is expanding its data center footprint in the St. Louis market by acquiring a historic building at 2300 Locust Street for conversion into a data center facility. This represents a significant expansion for TierPoint, which already operates in the region as one of at least 9 data center operators across 44 facilities in the St. Louis metro. The acquisition of a historic building suggests a retrofit or adaptive reuse project, which often requires specialized construction and MEP work. For BD professionals, this is a confirmed project in a mid-tier but growing market, and the adaptive reuse nature of the project may create opportunities for contractors experienced in converting older buildings to meet modern data center power and cooling requirements. Outreach should be timely as planning and design phases for such conversions typically move quickly once the acquisition is complete.

A St. Louis-based investor identified as Thomas has filed plans with the city of St. Louis to convert the Armory building into a data center, along with plans for a second data center facility. This is a confirmed retrofit project as formal documents have been filed with the city, indicating the project is actively moving through the planning and permitting stage. The project is located in the St. Louis, MO metro area, which represents emerging data center activity in a market not traditionally considered a primary data center hub. For BD professionals, this signals early-mover opportunity in the St. Louis market, particularly for vendors offering retrofit and adaptive reuse expertise, mechanical/electrical systems, and cooling infrastructure. With plans already filed, outreach should be timely as contractor and vendor selections are likely underway or imminent.

A multi-billion-dollar data center project is being pursued in the Midtown area of St. Louis, Missouri, with Rod Thomas of THO Investments having filed plans with the city. The project appears to be a new construction effort of significant scale, though specific capacity details in megawatts or square footage were not provided in the available snippet. The St. Louis metro area has seen enough data center activity to prompt a moratorium discussion in nearby St. Charles, indicating growing regional demand. For BD professionals, this represents a potentially massive opportunity in an emerging secondary market, and the multi-billion-dollar scale suggests substantial procurement needs across mechanical, electrical, and construction services. The project appears to be in early planning stages given that plans have just been filed, so outreach to THO Investments and monitoring of local permitting activity should be prioritized promptly.

A job posting for a Hyperscale Estimator role associated with Millstone Weber LLC in the St. Louis/St. Charles, Missouri area suggests the general contractor is actively pursuing or engaged in hyperscale data center work in the region. No specific developer, project size, or contract value is identified from this listing. The posting indicates that Millstone Weber LLC is building or planning to build capacity in hyperscale data center estimation, which is an early signal of potential data center construction activity in the greater St. Louis market. For BD professionals, this is a low-certainty but notable indicator that hyperscale projects may be in the pipeline in this metro, warranting further investigation. Urgency is low given the indirect nature of the signal, but monitoring Millstone Weber's activity and any related land or permitting filings in the area would be prudent.

Connect Data Centers has one planned data center facility in the St. Louis, Missouri colocation market, described as hyperscale capable, though no existing facilities are currently operational under their name in the market. No details on project size, construction timeline, general contractor, or contract value are available from this listing. The St. Louis market appears to be an emerging opportunity for hyperscale-capable colocation, which could signal future demand for construction and infrastructure services. For BD professionals, this is a very early-stage signal with minimal detail, so it warrants monitoring but is not yet actionable without further intelligence on the project's scope and timeline.

A data center proposal in St. Louis, MO has been revamped with a significantly increased price tag of $3 billion, indicating a major shift in project scope and ambition. The revised plan notably excludes the Armory building from data center use, instead repurposing it as office space, suggesting the data center component will be built as new construction at the site. The specific developer or operator behind the project is not named in the available details, and the project appears to still be in the proposal stage. For BD professionals, this is a significant signal in the St. Louis metro market, as a $3 billion investment would represent one of the larger data center developments in the region and could drive substantial demand for construction services, power infrastructure, and cooling systems. The urgency is moderate — the project is still being shaped and the revamped proposal suggests plans are evolving, making this an ideal time for early engagement before contracts are finalized.

This snippet references the St. Louis, Missouri data center market and mentions the Mastercard Technology Campus as a small, operational facility in the region. No specific new project, expansion, or construction details are provided — this appears to be a general market overview listing rather than a discrete project announcement. Mastercard is identified as having an existing presence in the St. Louis metro, but there is no named general contractor, project size in MW or square feet, or contract value disclosed. For BD professionals, this signal is low-urgency and primarily useful as background context on the St. Louis colocation and enterprise data center landscape rather than an actionable near-term opportunity. Further research would be needed to determine if any new construction or expansion activity is planned in this market.
