Uncovering Hidden Costs in Construction Operations

Read time: 3 minutes

Welcome to the 41st issue of the Punchline Memo, specifically tailored for leaders in construction and the built environment!

Construction industry businesses are often blindsided by costs that don’t show up in straightforward line items. While materials, labour, and equipment grab the spotlight, hidden costs quietly chip away at your margins.

The good news?

Once identified, these sneaky expenses can often be reduced or eliminated entirely.

1. Overtime Overload

Overtime might seem like the easiest way to hit deadlines, but it’s a costly habit. Studies show that worker productivity drops sharply after 40 hours per week, leading to diminishing returns. If overtime is your norm, you’re not only paying more but also setting the stage for burnout and costly mistakes.

Real Example: A contractor in Manchester reduced labour costs by 18% after introducing staggered shifts during peak project phases. Workers were more productive, and projects stayed on track.

What to Do: Use workforce management software to track labour hours and predict where additional shifts might be needed before it’s too late.

2. Equipment Expenses

Rental equipment is a money pit when it’s not properly managed. You might think you’re getting the most out of your machinery, but the costs of underutilisation add up fast.

Real Example: A contractor in Bristol saved £25,000 annually by introducing a fleet management system that identified unused rentals, allowing them to terminate unneeded contracts early.

What to Do: Set up weekly reviews of your equipment use. If something hasn’t been touched in two weeks, return it or reschedule its use.

3. The Cost of Rework

Mistakes cost money. Rework accounts for 5–9% of total project expenses on average. And more often than not, it’s caused by poor communication or unclear project plans.

Real Example: A London-based firm cut rework expenses in half by adopting a digital document system, which ensured every stakeholder had up-to-date specs and plans.

What to Do: Make project specs accessible to everyone through a centralised system. Apps like Autodesk Build or Procore make this process simple and effective.

4. Change Order Chaos

Uncontrolled change orders are profit killers. A survey found that poorly managed changes added 10–12% to project budgets. The problem often boils down to a lack of process for managing adjustments efficiently.

Real Example: A mid-sized contractor in Leeds improved profit margins by 8% after standardising their change order system with clear approval timelines for clients.

What to Do: Implement a robust change order policy. Get every alteration signed off in writing and keep a log of approvals.

5. The Domino Effect of Delays

Delays come with a cost that goes beyond the obvious. Extended equipment rentals, added labour, and wasted materials can spiral quickly.

What to Do: Use scheduling tools to track your project’s critical path and flag delays before they snowball into bigger problems.

One Actionable Tip
