Construction Software Companies & Consultants in Chesterfield, MO

Byrne Software Technologies, Inc. is an IT consulting and software firm based in Chesterfield, Missouri, in the St. Louis area. It was founded in 1985 and has now been in business for forty years. Its construction practice helps facility owners and building companies adopt, configure and connect project control software.

The company also runs divisions for government agencies, benefits administration, general IT services, network hosting and staffing. That breadth suits buyers who want a technology partner able to manage the systems around a single application.

Construction Technology Work

Construction management is one of the firm's named service lines. Its consultants combine specialized skills with an understanding of the business and technical questions that arise throughout the project management life cycle on capital projects. Two long-running relationships with construction software vendors anchor this work.

• Prolog: Byrne implemented the Prolog product in 1999, and that project introduced its staff to the Prolog software group. The firm then built implementation, integration and ongoing programming services for Prolog clients. It became an integration partner of Meridian, which owns Prolog, in 2000, and in 2004 it began selling the product in its region.
• Kahua: Byrne partnered with Kahua in 2018 to expand its services for facility owners and construction companies, with a focus on implementing and integrating construction control software.

For public agencies, including those that oversee building activity, Byrne provides services for the Accela Civic Platform. It states that it has the largest staff dedicated to Accela services. Relevant solution areas include building permitting, planning and zoning, fire protection and code enforcement. The company also offers a Bluebeam integration, an automatic GIS update solution, custom payment adapters, and custom public web and mobile tools.

Broader Technical Capabilities

Construction clients can also draw on the professional services group, which works with a range of technologies and covers the following areas:

• Custom web, cloud, mobile and desktop software development
• Business intelligence dashboards with drill-downs, charts and maps
• System integration and technology infrastructure planning
• Application design and technology consulting
• Project management by certified managers, from needs analysis through scope control
• SharePoint work, from basic configuration to enterprise portals
• Accela data conversion, interface development, scripting and custom training
• Network engineering and hosting
• Selective staffing, with recruiters who interview and validate candidates

The firm was approved as a Microsoft partner in 1988. It became an Oracle partner in 2019, having worked with Oracle products for more than twenty years before then.

Background and Approach

William Byrne started the company as William Byrne & Associates, writing custom programs for clients. It adopted its current name in 2006, saying the change better described the business while preserving a link to its roots. Work gained through Women's Business Enterprise status, awarded in 2008, helped it build a national client base.

In early 2024 it announced an Employee Stock Ownership Plan, which gives employees a stake in the firm and is meant to support continued investment and leadership continuity.

Jason O'Bryan is president, and Bill Byrne chairs the board. The leadership group also includes senior managing directors, managing directors, a controller and a director of sales and business development. The client base spans small, family-style private companies through to the largest corporations.

The firm says it offers clients a choice of ways to run a project, and it stresses clear communication and joint working. St. Louis media outlets have named it Best in Value and listed it among the area's largest IT companies.

For buyers, its main distinction in construction is a long record with Prolog and Kahua, backed by in-house development and integration staff.

Software Design Partners (SDP) is a custom software developer and technology consultancy headquartered in Chesterfield, Missouri, in the St. Louis area. It acts as an outsourced technology department for organizations that need senior IT leadership, development capacity and data expertise without hiring a full internal team.

Construction buyers should note that SDP builds tailored systems rather than selling a packaged construction platform. Its site lists no off-the-shelf construction product. However, its blog covers how contractors use AI agents to accelerate estimates, surface scheduling risks and catch likely change orders, with those agents drawing on project records such as daily reports, RFIs and plan sets.

Practice areas

The firm groups its offerings into seven areas, which can be combined into one engagement:

• Strategy and consulting: digital transformation, aligning technology with business goals, part-time executive technology leadership, process automation and build-versus-buy analysis
• Development and integration: bespoke applications, modernizing legacy systems, connecting disparate systems, mobile apps, and testing and support
• Business intelligence: dashboards, interactive reporting, data modeling and Microsoft Power BI
• Data management: warehousing, stewardship, and data transformation and integration
• Cloud adoption: planning, cloud-native development, migrating and integrating applications, and Microsoft Azure
• Application management: enhancements, modernization, performance and scalability tuning, and on-call help
• Artificial intelligence: AI planning, workflow optimization, chatbots and machine learning

How SDP works

SDP develops software in iterative cycles with heavy client participation and says experienced leadership should stay involved from start to finish. Projects can be standalone builds or extensions that connect to commercial packages a company already runs. For a contractor, that could mean linking existing accounting or project tools rather than replacing them.

After launch, the firm offers maintenance, content management and ongoing support. Its business intelligence work centers on KPI dashboards with drill-down views and role-based security, so field and office teams see only the data relevant to them.

Technology

The firm works mainly in the Microsoft ecosystem: .NET and .NET Core, SQL Server with SSIS and SSAS, Power BI, PowerApps, Office 365, and Azure services such as Functions, App Service, Cosmos DB, Blob Storage and Active Directory. It also lists AWS, React, Angular, VueJS, NodeJS, Java and C++. Mapping tools include MapBox, LeafletJS and Google Maps, and it uses Apache Cordova for mobile apps along with Bluetooth and 4G LTE connectivity. These skills suit location-aware and field-based applications.

Background and clients

SDP calls itself a Midwest technology firm focused on lasting client relationships. Its stated values include collaboration, innovation, accountability and a client-driven approach. Its longest-featured relationship is with Anheuser-Busch, spanning many years and a large number of projects, including a Codebook mobile app, GPS tracking and retail account planning tools.

Other examples include a loan documentation tracking system for The Servion Group and work on Castit, an ERP built for foundries that covers quoting through certification and shipping. Testimonials come from financial services and manufacturing clients.

Construction firms looking for a local partner to build, integrate or modernize custom operational software, or to apply AI and analytics to project data, may find SDP a relevant option.
