Duty-based intervals and spare parts planning.
Convert duty and environment into maintainable schedules. Build an asset list of bollards, panels, and HPUs; feed counters/health pings (541–542) and climate factors (337). Select tasks from a library (734), generate calendarized plans, and export to O&M and SLA bundles (733, 738). This sustains crash rated bollard availability and predictable lifecycle costs (842). Include one-sentence context that naturally links upward to the parent hubs (this section and the chapter hub). Add SIRA context with a link to SIRA Bollards (UAE) when relevant. Link installation pages only if helpful: What to Expect and Installation Guide.
Important: This is a general guide. For live projects we develop a tailored
Method Statement & Risk Assessment (MS/RA) and align with authority approvals (e.g., SIRA) where in scope.
928.1 Purpose
Set PM intervals from duty, climate, and condition data for HVM bollards (734, 842).
This page shows how to translate usage (KPI) and environment into a preventive plan that maintains availability targets in your SLA. You’ll connect telemetry (541–542), select task templates (734), and produce intervals that balance risk, cost, and uptime. Where equipment is crash-rated, the plan preserves the tested performance envelope during service life.
Use this planner alongside 734 Preventive Maintenance Plan and lifecycle guidance in 842 Lifecycle & maintenance. Telemetry setup and thresholds are covered in 541 Remote Fault Logging, Counters, Health Pings and 542 KPI Set.

| Operations | Duty cycles, fail-state, safety devices & measures | Installation Guide |
928.2 Inputs
Ops/hour, environment, device types, failure history, KPIs (541–542, 337). Include crash rated bollard components.
Start with a clean asset register for lanes, bollards, HPUs, controllers, and field devices. Pull hourly operations and health pings (541), cycle time stats and MTBF (542). Capture site climate per 337 Hot Climate Design—heat, dust, and coastal exposure affect grease life, seals, and electronics.
Include failure history (what failed, root causes, time-to-repair) and any warranty constraints (see 854 Warranty & Spares Policy). If you operate under UAE approvals, note any inspection cadence that touches maintenance; coordinate with SIRA Bollards (UAE) as required.
928.3 Method
Blends manufacturer guidance with usage thresholds and predictive signals (543). Produces calendar and counters.
(a) Build your baseline from manufacturer recommendations by device class (e.g., electromechanical drives vs hydraulic). (b) Overlay duty bands from ops/hour and cycle-time variance. (c) Add predictive maintenance signals—temperature, vibration, pressure, and fault frequency (543). (d) Apply PM plan tasks per component.
Output both calendar-based (e.g., quarterly) and counter-based triggers (e.g., every N operations). Use operational dashboards (544) to watch drift: if a lane’s cycle times rise, pull-forward lubrication and seal checks. Keep a simple change log of interval tweaks and reasons, referencing 118 Change Log practice.
928.4 Outputs
Task lists, parts kits, intervals, and triggers. Uptime targets aligned to SLAs (738).
Deliver a machine-readable plan (for dashboards and O&M) and a human-friendly checklist per visit. Group parts into kits by task (filters, seals, fluids) and lane. Tie availability targets to 738 Service Levels & Availability, and specify your availability target and response windows.
Where crash performance could be affected (e.g., loose fixings, drain failure causing corrosion), mark those tasks as rating-critical and reference 421 Rating-critical dependencies.
928.5 Limits
Revise after SAT and first-year data (638, 118). Living plan.
Initial intervals are estimates until validated by SAT results (638) and one year of telemetry. Expect to lengthen or shorten intervals as KPI trends stabilize. Document every change in your maintenance change log (118) and re-brief the operator team.
928.6 Spares & logistics
Min/max levels, lead times, storage conditions (856, 854). Practical availability for HVM bollards.
Define 856 Logistics, Storage & Handling rules: shelf-life, humidity, and temperature (especially seals and fluids in hot climates). Set spares policy with min–max stock levels and reorder points per lane. Note long-lead items and create a lane-down kit for rapid restoration. Store and label everything against the asset register.
928.7 Validation
Audits and compliance checks (728, 858). Close the loop.
Use 728 Site Audits & Compliance Checks to verify that tasks are completed to standard and that critical characteristics (e.g., drain function, fixings torque) meet acceptance. Add periodic 858 Quality Audits & Surveillance to sample work orders and spares management. Feed findings into interval tuning and training refreshers.
928.8 Save/Export
CSV to CMMS with IDs (911). Easy adoption.
Export a simple CSV with asset IDs (from 732), task codes, intervals (calendar/counter), parts kits, and warranty-sensitive steps. Map file names and IDs to the site’s conventions per 911 File Index & Naming Rules so your Ops team and SLA reporting can ingest it in the 730 As-Builts/O&M/Training stream or your dashboards.
928.9 Related
Operator workflows and dashboards (545, 544). Operational clarity.
For day-to-day execution, complement this planner with 545 Operator Workflows & Error-Proofing and 544 Operational Dashboards & Reporting. If you’re building the maintenance content pack, align with 733 O&M Manuals and 734 PM Plan.

928 Maintenance Interval Planner — FAQ
How often should automatic HVM bollards be serviced?
Use a blended approach: start with manufacturer guidance, then adjust by counters (e.g., every N operations) and telemetry trends (cycle-time change, temperature, vibration). In hot/dusty sites, shorten lubrication and filter intervals and review quarterly in year one.
What data do I need before setting intervals?
Collect operations/hour, cycle-time stats, recent faults, MTBF, environment (heat, dust, coastal exposure), and an asset register with serials. Add warranty constraints and lead times for critical spares.
How do SLAs influence the maintenance plan?
Availability targets and response windows in the SLA determine how conservative your intervals and spares levels should be. Higher uptime targets usually mean tighter intervals and a lane-down kit on site.
Can I export this plan to a CMMS?
Yes. Export CSV with asset IDs, task codes, calendar and counter triggers, parts kits, and safety checks. Follow the site’s File Index & Naming Rules so dashboards and reports can ingest it cleanly.
