Every package, every interface, every claim.
Rail, metro, airports, ports and highways. Bildstak federates your models, P6 programme, cost and contract documents across packages — and an AI analyst surfaces the risks.
Built for multi-package linear delivery.
From interface coordination to programme, claims, and portfolio risk — in one connected workspace.
Multi-package programme & EVM
Cost-loaded schedule and earned value across every package and alignment section. Variance and forecast-at-completion update as actuals flow in.
Interface & clash coordination
Federate civil, structural, systems, and track models. Find interface clashes across disciplines before they surface as a site instruction.
RFI & instruction register
A live register connected to Procore or Aconex — overdue flags, ball-in-court tracking, and a full audit trail across every section and contractor.
Claims & EOT builder
Assemble a variation or extension-of-time claim that cites the cause, RFI notice trail, schedule slippage, contract clauses, and cost quantum — one cited package.
Geospatial & asset data
Bring chainage, alignment, and PostGIS spatial data alongside the schedule and cost. Query the corridor and its assets in one place.
Portfolio risk — the Analyst
An autonomous analyst investigates each line or package and ranks the portfolio by risk: cost, schedule slip, open claims, interface gaps — with the evidence behind each.
Connects what you already use.
Primavera P6, IFC / BIM models, Procore, Aconex, SAP, Maconomy, PostGIS, Excel, CSV, and PDF document libraries. Thirty-plus source types, federated into one model. No middleware required.
See it on your rail or transport programme.
Bring your programme and cost export. We'll run the demo on your real project data.
Frequently asked questions
How does Bildstak work for transportation and rail projects?
Bildstak supports transportation and rail programmes with multi-package earned value management, interface and clash coordination, RFI registers across packages, EOT claims and delay tracing, geospatial and PostGIS data, and the Analyst — all federated from P6, cost ERP and document systems.

How does Bildstak handle multi-package megaprojects?
Bildstak handles multi-package megaprojects by federating every package's schedule, cost, RFI and document data into one model — so programme leadership can query across packages simultaneously, track interface risks, rank packages by performance and assemble claims without consolidating separate reports. 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 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 →
What is "the Analyst" in Bildstak?
The Analyst is Bildstak's autonomous risk investigation module. It cross-references every connected source — BIM, schedule, cost, RFIs, documents — ranks risks across the portfolio with evidence, and surfaces findings proactively, without needing to be asked a specific question.
