4D Scheduling & 5D Costing

4D Scheduling and 5D Costing represent the ultimate transition from passive 3D geometry to complete multi-dimensional project control. By linking critical path timelines (4D) and real-time financial tracking variables (5D) directly to individual parametric components, we transform static models into intelligent, live construction simulations that dictate exactly when an asset element is built and how much it will cost at that precise moment.
At PT. Buana Engineering Consultant (BEC), our Virtual Design & Construction (VDC) specialists synchronize master project management pipelines with automated quantity take-offs. This precise integration eradicates schedule volatility, balances institutional cash flows, and neutralizes budgetary risks before field deployment.

Services Overview

Our 4D and 5D BIM framework delivers complete, uncompromised visibility over a project’s physical and economic progress simultaneously. We eliminate standard spreadsheets and retrospective project reviews by loading master project schedules (such as Primavera P6 or MS Project) and live cost matrices directly onto the federated 3D model. This enables automated, step-by-step visual step simulations of the entire construction sequence. Project owners can visually track material flows, audit logistics, isolate construction supply choke points, and instantly view the financial impact of design modifications. This level of algorithmic precision ensures total budget data control and zero material waste.

Benefits & Solutions

Dynamic Visual Sequencing

Simulate the entire construction lifecycle chronologically on screen to expose logistical staging bottlenecks, crew cross-over risks, and critical path delays early.

Live Budget Transparency

Extract instantaneous, exact Bill of Quantities (BOQ) and itemized cost take-offs directly from geometry modifications, eliminating manual spreadsheet accounting human errors.

Cash Flow Optimization

Generate predictive, curve-accurate financial progress reports to balance resource outlays, coordinate milestone billing, and maintain strict corporate liquidity control.

Change Order Defense

Defend project budgets against contractor claim inflation by cross-verifying physical progress modifications with objective, model-embedded parameter sheets.

Questions? You Need Answer

While a standard 3D BIM model handles spatial coordinates and structural geometries, 4D BIM injects the element of time data, mapping the construction schedule to the objects. 5D BIM integrates the financial layer, linking cost calculations, labor rates, and material pricing directly to that same synchronized timeline and geometry asset.
