What IT Issues Cause the Most Downtime for Construction Companies?

Published February 2nd, 2026 by Canetadmin

For 10–25 employee construction companies, the majority of downtime comes from 5 preventable IT issues: internet outages, email failures, outdated hardware, lack of backups, and cybersecurity incidents. Even short outages can delay bids, payroll, and project coordination. With proactive managed IT services, most construction firms can reduce downtime by 50–70% and avoid the emergency disruptions that cost both time and money.

1. Internet and Network Outages

Construction offices rely heavily on internet access for:

Cloud-based project management

Email communication with vendors and clients

File sharing for plans and drawings

Unmonitored networks, aging firewalls, or single-point internet connections often cause outages that bring work to a halt.

2. Email Problems and Server Failures

Email outages are more than an inconvenience. They can:

Delay bids and approvals

Interrupt communication with job sites

Prevent access to shared files

Common causes include misconfigured systems, spam overload, and lack of proactive maintenance.

3. Outdated or Failing Hardware

Many small construction companies run:

Old desktops and laptops

Aging servers

Unsupported operating systems

Failing hardware leads to slow performance, crashes, and unexpected downtime — often at the worst possible time.

4. Missing or Unreliable Backups

Without proper backups, simple mistakes become disasters:

Accidental file deletion

Corrupted updates

Hardware failures

Companies without tested backups can experience days of downtime instead of hours.

5. Cybersecurity Incidents

Ransomware, phishing, and malware are major downtime drivers. A single compromised email account can:

Lock access to job site plans

Disrupt accounting and payroll

Force systems offline during cleanup

Most incidents start with one unprotected user account.

How Managed IT Reduces Construction Downtime

A proactive managed IT approach helps prevent downtime by:

Monitoring systems 24/7

Applying updates before failures occur

Detecting security threats early

Backing up data automatically

Responding quickly with onsite support when issues arise

Prevention is far less costly than emergency recovery.

Real-World Example

A 18-employee construction company experienced frequent internet outages and slow systems, averaging 6–8 hours of downtime per month. After moving to managed IT with proactive monitoring and hardware upgrades, downtime dropped to under 2 hours per month, and emergency IT calls were virtually eliminated.
