Programme intelligence for construction
No Slip captures weekly programme variance from MS Project, Asta, or P6. Every snapshot is timestamped, immutable, and built for client reporting and forensic delay claims.
| Site | Status | Variance |
|---|---|---|
| Long Marston WWTW | RED | -5d |
| Holt Heath Reservoir | AMBER | -2d |
| Alderton Pumping Stn. | GREEN | 0d |
| Tewkesbury South | GREEN | +1d |
Trusted by contractors delivering the UK’s most critical infrastructure programmes.
The Problem
When a contractor faces a delay claim, the question is not whether slippage happened. The question is whether the contractor has a contemporaneous, defensible record of when slippage happened, what caused it, and who recorded it. Most do not. They reconstruct the story from emails and revised Gantt charts months after the fact. That reconstruction loses in adjudication.
Weekly programme updates live in disconnected Excel files no one can audit.
Clients cannot read MS Project files. Reporting takes hours every week.
Without a structured weekly record, delay events become unprovable.
The Solution
No Slip imports your planning tool's export, calculates variance against baseline, captures the cause of any slippage, and locks the snapshot. Every week. Every site. Forever.

What No Slip does
Slippage Tracking
Upload your MS Project, Asta, or Primavera export. No Slip calculates variance per site, assigns RAG status, and creates an immutable snapshot record. Your week-on-week programme history builds automatically.
Stakeholder Reporting
A clean view of every site in your programme. RAG status at a glance. Variance in plain days. Trend lines that explain themselves. No more PowerPoint marathons every Friday.
Defensibility
Every snapshot is timestamped, attributed, and immutable. Every action in the platform is logged in an append-only audit trail. When a delay claim arises, your evidence is already there, structured, and admissible.

What makes No Slip different
A delay claim costs UK contractors between £50,000 and £150,000 in expert fees before adjudication even begins. The bottleneck is reconstructing what happened, week by week, with admissible evidence. No Slip turns your weekly programme reporting into a delay chronology, cause attribution summary, and critical path impact statement.
No Slip is a data platform, not a claims consultancy. The forensic module produces analysis based on user-inputted programme data and is intended for use with qualified legal and delay analysis professionals.
Proven in the field
Catchment Civils
A Tier 1 civils contractor delivering ten wastewater treatment sites under an AMP8 framework replaced their weekly Excel-and-PowerPoint reporting cycle with No Slip in March 2025. Within six weeks the client moved from monthly review meetings to weekly self-service dashboard access.

Northern Infrastructure Group
A mid-tier civil engineering contractor on a regional highway scheme used No Slip's forensic delay analysis module to support a substantial extension of time claim. The contemporaneous weekly snapshot record, supplemented by the cause attribution summary, became the primary evidence in adjudication.

Westwater Frameworks
A small regional civils contractor with a single in-house planner deployed No Slip to handle weekly reporting for three sites under a water company framework. The story is not about scale or claims. It is about how a small team replaced their reporting overhead without spending a week learning a new system.
