Construction Industry Challenges We Solve
We understand the unique demands of the construction and building technology industry and build solutions that address them head-on. With a market size of $18B global construction tech market, theconstruction sector demands technology partners who truly understand the industry.
Project Management & Scheduling
Construction projects involve hundreds of tasks with complex dependencies, multiple subcontractors, weather delays, and material delivery timing. Critical path scheduling, resource leveling, and real-time progress tracking are essential to keep projects on time — yet the industry still often relies on spreadsheets and paper.
Budget Tracking & Cost Estimation
Construction cost overruns average 80% on large projects. Accurate estimation requires databases of current material costs, labor rates, equipment rentals, and historical project data. Real-time budget tracking with change order management helps prevent cost surprises.
Safety Compliance & Incident Tracking
Construction is one of the most dangerous industries, with OSHA requiring detailed safety documentation. Digital safety platforms must track certifications, conduct toolbox talks, report incidents, manage PPE compliance, and provide real-time safety dashboards for multi-site operations.
Subcontractor & Vendor Management
General contractors coordinate dozens of subcontractors per project. Managing bid invitations, contract negotiation, schedule coordination, payment applications, lien waivers, and performance evaluations requires sophisticated vendor management platforms.
How We Help Construction Businesses
Our team brings deep construction domain knowledge combined with technical excellence to deliver solutions that work in the real world — not just in demos.
Digital Project Management
We build construction project management platforms with Gantt scheduling, critical path analysis, daily logs, photo documentation, RFI tracking, and real-time progress dashboards — giving project managers visibility across every job site from their phone.
Cost Estimation & Budget Control
Our estimation tools use historical cost databases, material price feeds, and parametric models to generate accurate estimates. Real-time budget tracking with change order workflows ensures financial control throughout the project lifecycle.
Safety & Compliance Platforms
We create digital safety systems: certification tracking, toolbox talk management, incident reporting with photo/video, OSHA log generation, and safety scorecards that help contractors maintain excellent safety records across all projects.
Subcontractor Portals
We build vendor management platforms that handle the full subcontractor lifecycle: prequalification, bid management, contract execution, daily reporting, payment applications, lien waiver tracking, and performance scoring.
Legacy App Modernization Capabilities We Apply to Construction

Modernize one module at a time — reducing risk, delivering value early, and keeping the business running throughout.
- ✓Business Logic Preservation
We extract and document the business rules embedded in legacy code so nothing gets lost in the new system.
- ✓Data Migration
Migrate from legacy databases (Access, FoxPro, SQL Server) to modern PostgreSQL or cloud-managed databases.
- ✓API Layer Design
Build modern REST or GraphQL APIs that let the new system talk to legacy components during the transition period.
- ✓Automated Testing
Create comprehensive test suites that verify the new system behaves identically to the old one for every critical workflow.
- ✓Cloud Deployment
Deploy the modernized application on AWS, Azure, or Vercel with CI/CD pipelines, monitoring, and auto-scaling.
