Construction systems by ENIGMA
How ENIGMA structures a connected construction operating platform
Commercial layer: leads, clients, estimates, BOQ, quotation, revisions, approvals and project conversion.
Project layer: sites, phases, teams, milestones, contractors, responsibilities, schedules and documents.
Material layer: purchase requests, vendor orders, receipts, site inventory, issue, transfer and consumption.
Execution layer: daily progress, site evidence, contractor work, approvals, variation and delay tracking.
Finance layer: bills, expenses, contractor payments, client billing, collections, project cost and reporting.
Industry Fit
Built for construction businesses where project control depends on connected workflows.
The operating model can be adapted to construction companies, EPC contractors, interior project businesses, infrastructure teams and multi-site contractors.
EPC project businesses
Engineering, procurement, site execution, approvals, project controls and reporting.
Interior & fit-out firms
BOQ, vendor coordination, material planning, site progress and client billing.
Infrastructure teams
Multi-site operations, contractor control, material movement and centralized reporting.
Operational Problems
Why construction operations lose control as projects multiply.
The problem usually starts when estimates, procurement, site progress, contractor bills and finance are managed in separate systems.
Estimate disconnect
Approved BOQ and quotation data do not flow cleanly into the project and procurement plan.
Material leakage
Purchase, receipt, site issue, transfer and consumption lack one traceable material history.
Contractor ambiguity
Scope, work done, measurement, approval and payment are difficult to reconcile.
Progress blind spots
Office teams see delayed progress reports instead of structured site evidence and milestone status.
Approval bottlenecks
Variations, purchases, bills and exceptions wait without clear ownership or ageing.
Project-cost delay
Revenue, cost, outstanding and margin visibility arrive too late for corrective action.
Connected Workflow
One operating flow from enquiry to project closure.
Lead
Capture requirement, client, source, site and opportunity context.
Estimate
Create BOQ, pricing, revisions, quotation and approvals.
Plan
Set project, team, budget, milestones and procurement needs.
Execute
Track site progress, material, contractor work and evidence.
Bill
Manage vendor bills, contractor bills, client invoices and receipts.
Report
Review cost, progress, delays, outstanding and project performance.

Construction Architecture
A controlled operating layer across office, site, procurement and finance.
ENIGMA can connect CRM, ERP, inventory, mobile field workflows, contractor portals, accounting and management reporting under one project data model.
Illustrative Workflow
COMMERCIAL
EXECUTION
FINANCE
Approved estimate to controlled site execution.
Estimate approved
BOQ, quotation, client scope and commercial approvals become the initial project baseline.
Material and contractor work tracked
Procurement, receipts, site issue, contractor scope and progress stay linked to the project.
Billing and cost update together
Contractor bills, vendor expenses, client invoices and collections feed project reporting.
This is an illustrative operating pattern, not a fabricated client result.
