The delay was in the schedule data six weeks before the progress report showed it.
A commercial project burns through its schedule float in the first quarter. Nobody flags it, because float consumption does not turn a status report red until the milestone is already missed. By the time the report goes red, there is no contingency left to protect.
An AI model trained on your last 30 projects reads that same schedule data every week. It sees float running at 2.3x the planned rate, names the activity driving it, and does it while there is still time to intervene.
The warning was always in the data. The point is to see it before it becomes a variation claim.
Most delay and cost overrun events follow patterns. The project that runs out of float in month two rarely recovers. The subcontractor who missed the first three milestones rarely delivers the fourth on time. The safety incident that happens on a Friday afternoon on a site without adequate supervision was foreseeable. AI trained on your historical project data surfaces these patterns on active projects before the damage is done.
According to a McKinsey analysis of more than 300 large capital projects, the average cost overrun is 80% and the average schedule delay is 20 months (McKinsey Global Institute, Reinventing Construction, 2017). KPMG's Global Construction Survey found only about a quarter of large projects came within 10% of their original deadline (KPMG, 2015). These are not freak events. They are the base rate, and a base rate is exactly what a model trained on your own project history learns to read early.
RaftLabs has shipped production software since 2015 for clients including Vodafone, T-Mobile, Aldi, Cisco, and Lockheed Martin, with AI, SaaS, and automation work across healthcare, fintech, and logistics. Construction is a newer vertical for us, and we say so plainly: the delay, cost, and safety models below build on the same schedule-data, computer-vision, and document-extraction work we have already shipped in operations-heavy industries next door. The team that scopes your problem in week 1 ships a validated v1 by week 12, then keeps iterating with you. Compliance requirements, OSHA, CDM, and GDPR, are scoped in week 1, not retrofitted before launch.
This works when you have project history and a specific risk to see earlier.
Everything on the left should already be true for your operation. Even one thing on the right, and a scoped model is not the right first step yet.
A fit01You run repeat construction projects and keep historical schedule, resource, and change order data from at least 20-30 completed projects.
02Delays, cost overruns, or safety non-compliance keep surfacing after the fact, in progress reports or post-incident, rather than before.
03You have a specific cost, schedule, or safety target and budget for a scoped build from $30,000.
Not a fitYou have no historical project records, or data lives only in disconnected spreadsheets no one maintains.
You want an off-the-shelf dashboard rather than a model trained on your own project data.
The decision you need is a one-off judgment call, not a repeatable pattern across many projects.
What we build
AI systems scoped to your project data
01Project delay prediction
Delay risk models trained on your historical project schedule data, resource utilisation logs, and milestone completion records. The model scores each active project weekly with a delay probability and the contributing signals, so project managers see which projects are at risk while there is still schedule contingency to protect.
02Cost overrun prediction
Cost risk models trained on your project cost history, change order logs, and resource consumption data. The model produces a cost-at-completion estimate and flags projects where the current trajectory puts the contingency at risk before the cost report shows it, giving commercial managers an early signal to review scope and subcontract exposure.
03Computer vision safety compliance monitoring
Camera-based safety compliance detection running computer vision over your standard CCTV feeds, covering PPE compliance, exclusion zone breaches during plant and machinery operation, and access route safety. Alerts reach site safety managers in real time with a timestamped image and location, backed by a full event log for audit trail and incident investigation.
04Contract and specification document extraction
An NLP pipeline that reads contracts, subcontract agreements, and technical specifications and extracts structured data: obligation dates, milestone payment triggers, penalty thresholds, and scope inclusions. Reduces per-contract review time and the risk of missing an obligation buried in a dense appendix.
05Equipment maintenance prediction
Predictive maintenance models for construction plant and equipment, trained on your maintenance history, usage logs, and fault records to predict failure before it causes downtime. Surfaces high-risk equipment so maintenance can be scheduled during planned downtime rather than during an unplanned breakdown that stops a programme-critical activity.
06Subcontractor performance scoring and BIM analysis
Performance scoring models that use your project records to build a milestone hit rate, defect rate, variation frequency, and safety event score for each subcontractor. BIM data analysis tools extract quantity and specification data from your models, cross-reference against procurement and programme records, and flag discrepancies against site installation records or purchase orders.
After shipping prediction and computer-vision systems in adjacent operations-heavy industries, our view on construction is specific. AI earns its keep where a decision repeats across many projects and the signal already sits in structured data nobody has time to read. It does not earn its keep on one-off judgment calls, or on sites with no usable data history. These are the four places it pays off first.
Schedule risk. Float consumption, milestone hit rates, and resource loading are numeric, weekly, and repeat on every project. This is the strongest starting point for most contractors.
RFI and submittal triage. The volume is high and the pattern is consistent: which RFIs stall, which submittals bounce, which drawings drive the most queries. NLP over your RFI log surfaces the bottleneck before it becomes a delay claim.
Safety image analysis. Computer vision over existing CCTV catches PPE and exclusion-zone breaches continuously, not on the next safety walk. High value, but the one place we insist on a human in the loop.
Cost forecasting. Cost-at-completion from change-order velocity and committed-versus-actual spend gives commercial teams an earlier read than the monthly cost report.
What each system needs from you, and what it changes
| AI system | Data it needs | What it changes |
|---|
| Delay prediction | Planned vs actual milestones, resource logs, and change orders from 20-30 past projects | Weekly delay-risk score that names the driving activity while float remains |
| Cost overrun forecasting | Cost history, committed vs actual spend, change-order logs | Cost-at-completion estimate before the monthly cost report shows the gap |
| Safety image analysis | CCTV feeds from high-risk zones, plus your per-zone PPE rules | Timestamped non-compliance alerts to the safety manager, with a full audit log |
| Contract and submittal extraction | Native or scanned contracts, specs, RFI and submittal logs | Key obligations and bottlenecks surfaced in minutes instead of hours |
| Subcontractor scoring | Historical milestone, defect, variation, and safety records per sub | A data-driven performance record for procurement and early-warning flags |
We have watched enough data projects stall to name the failure modes up front, rather than discover them in week 8.
The first is dirty field data. Site data is entered under time pressure and is often incomplete, and a model is only as good as the milestone and cost records behind it. When history is thin, we scope a smaller first system and help structure data collection rather than promise accuracy the data cannot support.
The second is adoption on site. A delay score that lives in a dashboard no project manager opens changes nothing. We wire alerts into the tools your team already uses and design for the site manager's day, not a data scientist's.
The third is model trust on safety. A safety model that cries wolf gets muted, and a muted safety model is worse than none. We tune to the site's real risk tolerance and keep a person in the loop on every safety decision. The model flags. A human acts.

How it works
From scope to shipped
Every project follows the same four phases. Scope is locked and price is fixed before development starts.
- Week 1
01Discover and scope
We map your project data: what you have, what is missing, and which AI system your data supports. You leave week 1 with a written scope document and a fixed-price quote. No development starts without your sign-off.
- Weeks 2-3
02Design and architecture
Model selection, data pipeline design, and system architecture before a line of production code is written. Decisions made here cost ten times less than the same decisions made in week 8.
- Weeks 4-12
03Build, integrate, and QA
Working system at a staging environment by the end of sprint one. Bi-weekly demos. QA runs in parallel with every sprint, not as a phase at the end. Integration with your project management system tested before launch.
- Weeks 12+
04Launch and post-launch support
Production deployment with monitoring activated on launch day. 8 weeks of post-launch support included in every project. Alert thresholds and model retraining cadence confirmed before handover.
Where you land depends on scope and data availability, not negotiation:
- Single-system build, $30,000-$80,000
- A focused build such as a delay prediction model or a computer vision safety monitoring deployment, scoped against your project data.
- Multi-system build
- Delay, cost, and subcontractor scoring together. Runs higher, scoped and fixed-priced during a paid discovery phase before any development starts.
What it costs
One system, scoped against your data, starting at $30,000.
We assess your project data during a paid discovery phase and produce a firm quote before any development starts.
Starts at $30,000A focused single-system build is the common starting point. Multi-system builds get scoped and priced during discovery, once the first system is running.
The discovery quote locks in one system's scope and timeline. Once it's running, we scope the next system against real results, not a guess made before you saw anything.
No hourly billing
Once we scope the system against your data, that price is locked in writing, no surprise invoices, no change fees you didn't agree to.
Post-launch support
Production deployment with monitoring activated on launch day, plus 8 weeks of post-launch support included in every project.
