Resource utilisation KPIs for Indian AEC firms

Utilisation is the single most important operating metric for any consultancy-shaped AEC business. If your senior architects are 50% utilised, you're underbilling or overstaffed. If they're at 110%, something's about to break. This post is the short list of KPIs that matter.

1. Billable utilisation

Formula: (billable hours worked) / (available hours) × 100

"Available hours" = standard working hours (~40/week) minus leave and holidays.

• Healthy range for a senior architect: 65–75%.
• Healthy range for a junior: 75–85% (more execution, less client management).
• Over 85% sustained = burnout + mistakes.
• Under 60% sustained = either staffing imbalance or bench problem.

2. Project utilisation

Formula: (allocated resource-weeks on a project) / (planned resource-weeks) × 100

Tracks whether the project is consuming more or less effort than estimated. Over 120% = scope creep or underestimation; under 80% = smoother-than-expected or the work isn't happening.

3. Realisation rate

Formula: (billed hours) / (tracked billable hours) × 100

Tracks how much of your billable effort actually turned into revenue. The difference is usually write-offs — hours worked that weren't billable at full rate (client pushback, scope creep you absorbed, rework).

• Healthy: 90–100%.
• Under 85% = you're absorbing scope creep instead of issuing change orders.

4. Pipeline-to-capacity ratio

Formula: (signed work, next 90 days, in weeks of effort) / (available capacity, next 90 days, in weeks)

The leading indicator. Above 1 = you need to hire or subcontract. Below 0.7 = you need sales effort.

Where Blueprint surfaces these

Blueprint's resource planning module tracks allocations and Blueprint's time tracking captures billable vs non-billable hours. The utilisation view rolls the two together:

• Per-user utilisation this week, last 4 weeks, last 13 weeks.
• Per-project utilisation vs plan.
• A flagged list of anyone over 90% or under 60% sustained.

The caveat

Utilisation is a blunt instrument. The moment you optimise for the number, the number gets gamed — "billable" entries that aren't, hours stretched to hit a target. Use it as a leading indicator, not a performance metric. Pair it with realisation rate — if utilisation is up but realisation is falling, you're not actually earning more.
