Construction IT has to work in a trailer, a truck and the office

The short answer

IT support for a construction company has to cover the office and the field. The field side is what makes it different: phones and tablets used on job sites, internet in trailers and remote sites, field apps that sync with the office, and bids, plans and payment details that criminals actively target. The office side covers the usual computers, email, accounting and estimating software, and backups.

The goal is simple: a superintendent can open the current drawings, log the day and approve a change order from any site, and the office knows every device and account is under control. The sections below cover each piece and what to ask an IT provider.

Field devices: phones, tablets and laptops

Field devices get dropped, left in trucks and passed between crews. Treat them as company equipment that can be lost on any day.

• Manage every device centrally. Mobile device management lets you push field apps, require a passcode and encryption, and wipe a lost tablet remotely. Microsoft Intune, included in Microsoft 365 Business Premium, is one common option.
• Use rugged cases or rugged models for anyone working outside. They cost less than replacing screens every few months.
• Avoid shared logins on shared tablets. If a crew shares a device, use the app’s shared-device mode or separate profiles so you know who did what.
• Keep a simple inventory of who has which device, so you can recover it when someone leaves.
• Protect personal phones lightly. If foremen use their own phones for email, app protection keeps company data inside work apps without managing the whole phone.

Internet at the job site

Drawings, photos and video calls all need a connection, and many sites start with none. Common options, from simplest to most robust:

• Phone hotspots for a single user on a short job. Cheap, but slow and drains batteries.
• Cellular routers with an external antenna in the trailer. Good for most sites, especially with a plan from the carrier with the strongest local signal.
• Dual-carrier routers that switch between two cellular networks if one drops.
• Satellite internet for remote sites without good cellular coverage.

Whatever you use, put a business-grade router or firewall in the trailer, change default passwords, and keep a separate guest network for subcontractors. A trailer network that anyone can join is an open door to company laptops.

Field apps and the office systems behind them

Most contractors now run project management in a field app, plus estimating, scheduling, accounting and payroll systems in the office. The value comes from connecting them.

• Store current drawings in one place that syncs to field devices, and make older sets read-only so nobody builds from a superseded sheet.
• Make sure large plan sets are available offline for sites with weak signal.
• Connect field apps to accounting where you can, so approved change orders and timesheets do not get re-keyed.
• Use one company login, with multi-factor authentication, for as many apps as possible, so turning off a leaver’s access is one step instead of ten.

Our systems integration work connects field, CRM and accounting systems so data moves without retyping.

Protecting bids, plans and payments

Bids and plans

Bid numbers, estimates and owner drawings are valuable to competitors and sometimes confidential under contract. Limit who can open the estimating folder, use sharing links that expire, and remove access the same day an estimator or project manager leaves. Our employee offboarding checklist covers the steps.

Wire fraud

Construction moves large payments between owners, general contractors, subcontractors and suppliers, which makes it an attractive target for business email compromise. Criminals take over or imitate an email account, then send new bank details just before a payment is due. The FBI’s Internet Crime Complaint Center reported 21,442 business email compromise complaints and about $2.77 billion in losses in 2024.

1. Turn on multi-factor authentication for every email account, including the owner’s.
2. Verify any change in payment instructions by calling a known number, never one in the email.
3. Require two people to approve new payees and bank changes.
4. Use email filtering that flags lookalike domains and external senders.
5. If a fraudulent wire goes out, call your bank immediately and report it to the FBI at ic3.gov.

Not sure how secure your field and office setup is? Contractors often have devices, accounts and shared folders nobody has reviewed since the last big job. Our free Technology Health Assessment takes about 30 minutes of data collection. The next day you get a plain-language report rating your IT operations, cybersecurity, applications, business continuity and technology spending, with a short list of next steps in order. It is yours to keep, with no obligation. Book your assessment.

A standard kit for every new project

Most construction IT headaches start when a new job ramps up in a hurry. A standard kit makes each start-up predictable.

• A trailer router and antenna, pre-configured with your settings and a guest network
• Enrolled tablets with the field app, current drawings and a charger bank
• A project folder created from a template, with permissions set for the project team only
• A shared project mailbox or channel so communication does not live in one person’s inbox
• A closeout step that archives files, returns devices and removes subcontractor access when the job ends

Writing this down once saves hours on every job and keeps old projects from becoming security gaps.

The office side still matters

• Back up accounting, estimating and project files, with an off-site copy and regular test restores.
• Keep office computers patched and protected with endpoint protection.
• Plan for peaks: a new project can mean ten new users in a week. Have a standard setup ready.
• Check what your insurer asks. Many cyber-insurance applications ask about multi-factor authentication, backups and endpoint protection, so keep evidence of each control ready.

CISA’s guidance for small businesses is a good free reference for the basics.

What to ask an IT provider

• Can you manage field phones and tablets, and wipe one the same day it is lost?
• How do you handle internet at new job sites?
• Can you connect our field app to our accounting system?
• How fast can you set up a new hire’s laptop, phone and accounts?
• Can someone come on-site when needed?
• How do you keep subcontractors and former staff out of our files once a job closes?
