From cost variance to the element that caused it.
You own the forecast. Bildstak connects your cost data to the model and the schedule, so a number in the variance report is one click from the component behind it.
The forecast is only as good as the trail behind each number.
Cost lives away from the model
Procore, Maconomy, and SAP hold the numbers. The model holds the scope. Joining them is a spreadsheet exercise every reporting cycle.
Variance without a cause
The report shows the project is over by a percent. Finding out which package, which element, and why takes the rest of the afternoon.
Forecasts age fast
By the time the cost-at-completion is assembled, the inputs have already moved. You are forecasting from last week.
What Bildstak gives you
Cost joined to scope
Procore, Maconomy, and SAP connect directly. Every cost line maps to the model element and the work package it belongs to.
Integrations →Drill from the summary down
Start at the variance summary and click through to the package, then the element. The trail behind each number is one step away.
Reports and dashboards →Cost-at-completion that stays current
Forecasts rebuild as the source data changes, so the number in front of you reflects today, not the last manual roll-up.
Federation engine →Drill from a variance summary to the element on the model.
The dashboard shows open clashes, RFI cycle time, and cost variance at a glance. When a number moves, click it. Bildstak takes you to the work package, then the element in the 3D viewer, with the cost line and the source record from Procore or SAP attached. Approved changes write back, so the ERP and the model never disagree.

Reporting cycles get shorter
The roll-up is already assembled, so the cycle is spent reviewing, not collecting.
Every number has a trail
A variance figure is one click from its cause, so reviews move straight to the decision.
One agreed set of figures
Cost, model, and schedule draw from the same join, so finance and delivery work from the same numbers.
Frequently asked questions
How does Bildstak help project controls and cost managers?
Bildstak gives project controls teams a live cost-loaded schedule with earned value management, cost variance across packages, and RFI overdue tracking — all joined from Primavera P6, the cost ERP and the document system in one federated model you can query in plain English. Read the full answer →
How does Bildstak do earned value management?
Bildstak delivers earned value management by loading your Primavera P6 schedule with cost data from your ERP (SAP, Maconomy or equivalent), then calculating CPI, SPI, EAC and variance at completion in real time — with every metric cited back to the source records. Read the full answer →
How do I see cost variance across my portfolio?
Bildstak's portfolio module federates cost and schedule data from every connected project, then ranks them by cost variance, spend-to-date, EAC and claim exposure — so portfolio directors see which projects need intervention without waiting for monthly reports. Read the full answer →
What is a cost-loaded schedule?
A cost-loaded schedule is a project programme where each activity has a budget and resource rate assigned, so that cost is earned as work progresses. It is the foundation of earned value management — linking schedule performance to financial performance in a single integrated model. Read the full answer →
How do I assemble an EOT claim with Bildstak?
Bildstak's Claims Builder assembles an EOT claim by tracing the delay chain — cause event → RFI notice trail → programme slippage → contract entitlement clause → cost quantum — across every connected source, then exports a cited PDF package ready for submission. Read the full answer →
