A computer-implemented, multi-modular, software-based construction project management system facilitates comprehensive construction project management from design to build completion stages. The management system provides a platform to network a series of computer clients for implementing a series of non-transitory, computer-implementable modules, including a first Design Input Conversion & Management module, a second Project Survey, Code Match & Organize module, a third Scheduling module, a fourth Vendor Selection & Bid Process module, a fifth Total Cost, Bid Evaluations & Contract Finalization module, a sixth Project Assembly & Quality Verification module, and a seventh Financial Accounting & Transactions module. Together the system-supportive modules operate to continually advance a construction project as initiated by design component data input into the system via the Design Input Conversion & Management module from an outside source provider and converted for use throughout the system as the project advances to completion.
