CMiC Construction ERP API
CMiC Construction ERP REST API for enterprise construction project management, job cost accounting, and subcontractor management. Enables AI agents to manage project cost control and job cost accounting for construction financial management, handle subcontractor prequalification and contract management for vendor risk management, access project forecasting and earned value analysis for construction project controls, retrieve RFI and submittal management for project documentation workflow, manage change order processing and contract modification for project change management, handle construction billing (AIA G702/G703, T&M, unit price) for project invoicing automation, access equipment and resource management for construction asset tracking, retrieve safety incident reporting and OSHA compliance for jobsite safety management, manage document control and BIM integration for project information management, and integrate CMiC data with payroll, estimating, and field management platforms.

⚡ Reliability
Best When
A large general contractor or construction manager using CMiC wants AI agents to automate job cost control, subcontractor management, change order processing, construction billing, and project financial reporting.
Avoid When
FINANCIAL RISK: CMiC construction billing integration generates AIA G702/G703 payment applications — automated overbilling or incorrect retainage calculations create contract disputes and lien exposure. Subcontractor compliance automation (insurance, lien waivers, certified payroll) must validate all required documents; incomplete compliance creates lien liability on owner's property. CMiC is on-premises or hosted deployment; API access requires direct database or middleware integration — not a modern cloud REST API for all modules.
Use Cases
- • Managing job costs from construction financial agents
- • Processing subcontractor contracts from procurement agents
- • Tracking project forecasts from construction controls agents
- • Automating AIA billing from project billing agents
Not For
- • Small contractors without enterprise construction ERP needs
- • Non-construction industries without job cost project accounting
- • Light commercial contractors without complex subcontractor management

Known Gotchas
- ⚠ BILLING RISK: Automated AIA G702/G703 payment application generation requires accurate stored material tracking and retainage calculation; overbilling or miscalculated retainage creates contract dispute and lien exposure
- ⚠ Subcontractor lien waiver compliance — automated subcontractor payment must collect conditional/unconditional lien waivers per state requirements; missing lien waivers create mechanic's lien liability on owner's property
- ⚠ On-premises deployment complexity — CMiC is primarily on-premises or hosted; API access may require middleware layer or database-level integration; not a modern cloud-native REST API for all modules
- ⚠ Legacy SOAP modules — CMiC has older modules (payroll, equipment) with SOAP/XML API; newer REST API coverage varies by module; verify REST availability per target module
- ⚠ No webhooks — job cost and project event notification requires polling; no native event push for change orders, billing, or subcontractor payment events
- ⚠ Multi-currency and Canadian operations — CMiC serves US and Canadian construction; verify currency handling and tax compliance for Canadian GST/HST in automated billing
