The schedule, the cost, and the claim.
No BIM model required. Bildstak connects P6, Maconomy or SAP cost, Procore or Aconex, and your contract documents — and answers in plain English.
Built for schedule, cost, and contractual risk.
Six modules purpose-built for civil and infrastructure delivery. No BIM required.
Claims Builder
Assemble a variation or EOT claim that cites the cause, RFI notice trail, schedule slippage evidence, contract clauses, and cost quantum. Everything in one cited package.
Cost-loaded schedule and EVM
Roll BoQ pay-item rates onto P6 activities. Earned value and cost variance update as actuals flow in from Maconomy, SAP, or your cost system.
RFI and instruction register
A live register connected to Procore or Aconex. Overdue flags, ball-in-court tracking, and a full audit trail of every status change and instruction.
Specification tracker
Track specifications component by component across the head contract and all supply contracts. Flag conflicts before they become RFIs on site.
Submittal schedule generator
Back-calculate submit-by dates from your programme and agreed lead times. Regenerate the schedule when milestones move.
Portfolio and supplier benchmarking
Rank every project by cost variance, open claims, and overdue RFIs. Benchmark supplier delivery rates and on-time performance across your portfolio.
Connects what you already use.
Primavera P6, Maconomy, SAP, Procore, Aconex, Excel, CSV, PDF document libraries, and PostGIS spatial data. Thirty-plus source types. No middleware required.

Does Bildstak work for projects without BIM?
Yes. Bildstak works without BIM on any project that has a schedule, cost data and a document system. Heavy civil, infrastructure, industrial and process programmes connect Primavera P6, an ERP, Procore or Aconex and contract documents — no IFC model needed — and get full intelligence.

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 →
How do I track RFIs across Procore and Aconex?
Bildstak federates your Procore and Aconex RFI registers into one unified view with ball-in-court status, overdue flags, and response-time analytics — so you can see every open RFI across both platforms in a single query without manual exports. Read the full answer →
How much does Bildstak cost and how is it priced?
Bildstak is priced per project, with two tiers plus optional add-on modules, so cost is predictable for procurement. Pricing scales with the project rather than per-seat, and a tailored quote is available on request. Read the full answer →
