Construction schedules, calculated and explained.

Answer a few questions and RunF9 builds the schedule with you. Already have one? Upload it and RunF9 checks it, compares every update and models delays.

Everything a scheduler does. Shown, not hidden.

RunF9 does the repetitive parts of scheduling and shows its work, so you can review and defend the result.

Build.

A baseline from a conversation.

RunF9 interviews you like a senior scheduler (scope, permits, long-lead equipment, site and calendar) and builds a CPM schedule with a written basis for every duration and link.

Check.

All 14 DCMA checks, every time.

Upload a P6 or MS Project file. Each failing check lists the activities involved and a suggested fix, with the published thresholds or your organization’s own.

Forecast.

Know the finish before it moves.

Monte Carlo risk analysis over the full network gives P50 and P80 finish dates. When a date slips, recovery options are re-scheduled and priced from your labor cost.

Every update. Every delay.

The baseline is the first week. RunF9 keeps working every month after it: what changed, why the finish moved, and what a delay does to the dates.

What changed this month

Upload this month’s P6 or MS Project update. RunF9 pairs it with the last one, activity by activity.

  • How far the finish moved, and which driving-path activities moved it
  • Critical path changes and float erosion
  • Logic, duration, lag, constraint and calendar edits
  • Actual dates that were rewritten since the last update

Every difference is listed with its activity ID, and exports to Excel.

Time Impact Analysis

Model a delay event as a fragnet, insert it into the status-date schedule and recalculate.

  • Finish and milestone dates before and after, and the days of impact
  • The driving path before and after, and float absorbed off the critical path
  • Potential concurrent delay flagged for the analyst
  • Inputs and results hashed: the same inputs reproduce the same answer

A schedule calculation, not an opinion on entitlement. The report (PDF, Excel) says so.

Built by a scheduler, for everyone on the project.

Native P6 and MS Project files

Import .xer and .xml with activities, logic, lags, constraints and calendars, and export the same formats. Excel and PDF imports read activities and dates; a PDF carries no logic.

Critical path and float

Forward and backward CPM passes with calendars, holidays, lags and constraints. Total and free float for every activity.

DCMA 14-Point Assessment

All 14 checks, with the published thresholds by default or your organization’s own.

An interview, not a blank page

Questions are ranked by how far each answer can move your finish date.

Risk and recovery

Monte Carlo analysis (200 to 1,000 iterations of the full network) gives P50 and P80 finish dates; recovery options are priced from your labor cost.

Ask AI, with limits

Plain-English questions and narrative drafts with a version-pinned model (Anthropic Claude by default, OpenAI as an approved alternate) or one inside your own network. Calculated figures such as DCMA results come from the engine, not the model. AI can be switched off.

Four steps. One finish date you can defend.

  1. 1
    Start

    Answer the interview, or upload a P6 (.xer), MS Project (.xml), Excel or PDF schedule.

  2. 2
    Calculate

    The CPM engine computes dates, float and the critical path. This is arithmetic, not AI.

  3. 3
    Check

    DCMA 14-Point checks, date logic and risk analysis, with the reason for every finding.

  4. 4
    Deliver

    Export to P6, MS Project, Excel or PDF, with a Basis of Schedule narrative. Then compare each update and model delays.

Reports, drafted from your numbers.

Drafted by AI from your schedule’s calculated figures. Review them before you send them: the figures come from the schedule, the wording from the model.

  • Executive Schedule Summary
    Status, key dates, findings and recommendations in plain language.
  • Critical Path Report
    Driving activities, float and low-float paths from the CPM calculation.
  • Baseline vs Current Variance
    Compares current dates with the baseline stored in your P6 or MS Project file.
  • Schedule QA/QC Report
    The DCMA 14-Point results, with the issues and suggested fixes.
  • Time Impact Analysis
    The delay event, its fragnet, the impact on each milestone and the driving path before and after, with input and result hashes.

Simple, transparent pricing.

Where these numbers come from

Every figure on this page is reproducible. Customers and auditors can ask us to run the tests below in front of them.

14 of 14 DCMA checks

All fourteen checks of the DCMA 14-Point Assessment are implemented, each with a unit test that makes it pass and fail. Checks that need data a file doesn’t have (for example baselines) are reported as not applicable, never as passed.

100,000 activities

An automated performance test schedules synthetic networks of 10,000, 50,000 and 100,000 activities, with mixed relationship types, lags and two calendars, on every code change. It measures the CPM calculation, not file upload.

0 days after a round trip

Five test schedules (different calendars, delivery methods and a required finish) are exported to P6 XER and MS Project XML, imported back and re-scheduled from scratch. Every activity’s early start, early finish and total float must match exactly. This proves RunF9’s files keep the logic intact; a side-by-side comparison with P6 and MS Project calculating the same reference projects is planned and will be published here.

Private beta

RunF9 is in a private beta. New firms join with an invitation, and members join through their organization’s admin. Plan limits are listed in the pricing table and enforced by the server.
