The verdict in three sentences
For 3 ready-mix concrete plants and an aggregate quarry around Denver, a CMMS costs an estimated $60 to $140 per user per month as SaaS in 2026, or $45,000 to $100,000 as a custom build, with 3 to 5 months of rollout. The real lever is preventive maintenance driven by hour meters on crushers, screens and wheel loaders, combined with a wear parts inventory tracked in real time. Cutting unplanned downtime from 6% to 3% of operating hours is worth several hundred thousand dollars a year on a site this size.
Where your 6% unplanned downtime comes from
In a quarry, stoppages cluster on a handful of assets: the primary jaw crusher, the secondary cone crusher, screens, conveyors and wheel loaders. At a batch plant, it is the mixer, the feed screws and belts, the air compressor and the mixer trucks. The cause is almost always the same: a wear part replacement (liners, jaw dies, screen media, belts) done too late because actual run hours are not tracked, or a part missing from the storeroom when the failure happens. MSHA workplace examination rules add a compliance reason to track inspections properly.
| Asset | Typical failure | Metric to track | Indicative preventive interval |
|---|---|---|---|
| Jaw crusher | Worn jaw dies, bearings | Engine hours, tonnage | Inspection every 250 h |
| Cone crusher | Worn mantle and bowl liner | Hours, CSS setting | Check every 500 h |
| Screens | Torn media, springs | Hours, vibration | Weekly check |
| Conveyors | Belts, idlers, pulleys | Hours, visual inspection | Daily walk-around |
| Wheel loader | Hydraulics, tires | Hour meter | Oil change every 500 h |
| Batch plant mixer | Paddles, arms, seals | Batch count | Check every 5,000 batches |
A suitable CMMS reads these meters automatically (PLC, equipment telematics) or through a mobile entry by the operator at the end of the shift, then triggers work orders at the right time.
SaaS or custom: comparing 5-year costs
For a team of 12 users (technicians, shift leads, storeroom clerk, maintenance manager), both options land in a similar range over 5 years. The difference is fit: generic SaaS CMMS tools handle work orders well, but batch counters, crushed tonnage and equipment telematics less so.
| Criterion | SaaS CMMS | Custom CMMS |
|---|---|---|
| Upfront cost | $4,000 to $12,000 configuration | $45,000 to $100,000 |
| Recurring cost | $60 to $140 per user per month | $400 to $1,000 per month hosting and support |
| 5-year total (12 users) | $47,000 to $113,000 | $69,000 to $160,000 |
| Batch and tonnage meters | Often manual import | Connected to PLC and truck scale |
| Offline mode in the pit | Varies by vendor | Designed in from day one |
| Time to go live | 1 to 3 months | 3 to 5 months |
| Data ownership | Vendor contract | Full |
Rule of thumb: if you only need work orders and calendar-based preventive maintenance, SaaS is enough. If you want preventive triggered by hours, batches and tonnage, and wear parts linked to purchasing, custom becomes competitive.
Wear parts inventory, the usual blind spot
A set of jaw dies costs $10,000 to $25,000 and supplier lead time can reach 6 to 10 weeks. Without visibility, the storeroom overstocks out of caution or, worse, discovers the stockout on the day of the breakdown. The CMMS must therefore manage, for each critical part, a minimum stock based on actual consumption, a reorder alert and a service life history per asset. On a fleet this size, cutting inventory value by 15 to 25% while eliminating stockouts is common.

Mike, maintenance manager for 3 ready-mix plants and a quarry near Denver, records 6% unplanned downtime over 2,200 annual operating hours at the quarry, so 132 hours. Each hour the primary crusher is down costs about $3,000 in lost production, purchased aggregate and idle crew time, so $396,000 a year. With a $75,000 custom CMMS and a 3% target, he recovers 66 hours, about $198,000 a year. The project pays back in under 5 months of operation. Illustrative scenario to adapt to your actual costs.
FAQ
How much does a CMMS for a quarry cost in 2026?
As SaaS, allow $60 to $140 per user per month plus $4,000 to $12,000 of setup. A custom build runs an estimated $45,000 to $100,000 with 3 to 5 months of rollout.
Can the CMMS connect to equipment meters?
Yes, through manufacturer telematics (AEMP/ISO 15143-3 APIs from the major equipment makers) or a mobile entry at shift end. Automation saves about 10 minutes of data entry per machine per day.
Does the CMMS work without coverage in the pit?
An app designed for offline use stores readings and work orders and syncs when the network returns. Check this carefully, as many pit floors have weak LTE coverage.
What reduction in unplanned downtime can we expect?
Sites moving from calendar-based to meter-based preventive maintenance commonly target a 30 to 50% reduction in unplanned stops. Going from 6% to 3% is a realistic 12 to 18 month goal.
Do technicians need training?
Yes, plan 1 to 2 days of training and a month of support. Adoption depends mostly on how simple mobile entry is, ideally under 2 minutes per job.
