A computer that can't run your estimating software, or dies the first time it's knocked off a ute tray, costs you far more than its price tag. Lost time, lost files and a scramble to replace it in the middle of a job.
There's no single best computer for a construction business. A drafter, an estimator and a site supervisor need different things. This guide covers the types of computers that suit different roles, what to look for in each, and the brands we'd shortlist.
Match the computer to the job
Desktops for the office
If someone works at a desk all day, especially on CAD, 3D modelling, rendering or big spreadsheets, a desktop gives you the most performance for the money. Desktops are also easy to upgrade and repair: open the case, swap the part. The downside is obvious. They don't leave the office.
Laptops for people who move around
Project managers and construction managers spend their days between the office, sites and meetings. A good business laptop does the lot: email, scheduling, project management software, reviewing plans and the odd bit of light CAD.
Mobile workstations for heavy design work
Engineers, architects and drafters who need serious power away from the desk should look at mobile workstations, such as the Dell Precision or HP ZBook ranges. They have professional graphics cards, 32 GB of RAM or more, and high-resolution screens. They're heavier and dearer than standard laptops, but they'll run demanding CAD and modelling software.
Rugged laptops for site
Site is hard on equipment. Rugged laptops like the Panasonic Toughbook range are built to survive dust, rain and drops. Their specs are usually more modest than an office laptop, but for a site supervisor that matters less than a machine that still works after a fall.
Look at the IP rating, which tells you how well a device resists dust and water. For working outdoors, also look for a bright screen (1,000 nits or more) so you can actually read it in the Queensland sun.
Tablets and 2-in-1s
Devices like the Microsoft Surface Pro combine a touch screen, stylus and detachable keyboard. They're great for marking up plans on site, taking notes during inspections and showing clients drawings. They're not workstations, but for most site and management tasks they're plenty.
What specs to look for
- Processor: a current-generation Intel Core Ultra or AMD Ryzen chip. Avoid older generations sold cheap, as they'll age quickly.
- RAM: 16 GB minimum. 32 GB or more for CAD, modelling or heavy multitasking.
- Storage: an SSD, not a hard drive. 512 GB at least, 1 TB if you store drawings, photos and video locally.
- Graphics: for CAD and rendering, a dedicated professional card, such as NVIDIA's RTX professional range (formerly Quadro) or AMD Radeon Pro. For office and site work, built-in graphics are fine.
Durability and portability
- Build: reinforced frames and spill-resistant keyboards help on site.
- Weight: lighter is easier to carry, but very light machines are often less tough. Find the balance for how the person actually works.
- Battery: a full day's battery and fast charging matter if you're on site without power.
Screen, keyboard and security
- Screen: high resolution for reviewing plans. Bigger screens are easier on the eyes but harder to carry. Most people end up with a laptop plus an external monitor in the office.
- Keyboard: comfortable and backlit.
- Security: a fingerprint reader or face login, plus encrypted storage. A lost laptop full of client details and plans is a real problem.
- Ports: USB-C and HDMI save you carrying a bag of adaptors.
Operating systems
- Windows runs most construction software, including most estimating, accounting and CAD packages. For most businesses, it's the safe choice.
- macOS is smooth and reliable and good for creative work, but check every program you rely on runs on it before you buy.
- ChromeOS is cheap and simple for web-based tasks, but won't run most desktop construction software.
Linux is worth a look
We use Linux, and it's a genuine option for a construction business. Distributions like Linux Mint and Pop!_OS are user-friendly, secure, run well on modest hardware and cost nothing to licence.
The catch is Windows-only software. There are three ways around it:
- Dual boot: install Windows and Linux on the same machine and choose at start-up.
- Virtual machine: run Windows inside Linux for the programs that need it.
- Wine: run many Windows programs directly on Linux without installing Windows.
If your business depends on one Windows-only program, test it before you commit. Plenty of tasks are now web-based anyway, which makes the operating system matter less.
Cost, warranty and repairs
Cheap computers often cost more over their life. Think about the total cost of ownership: purchase price, repairs, downtime and how long it will last.
- Warranty: one year is standard. For machines that go to site, an extended warranty or onsite service plan is worth considering. Remember the Australian Consumer Law also gives you rights beyond the manufacturer's warranty if a product fails early.
- Repairability: check how easily the device can be opened, whether parts like batteries, screens and keyboards are available and affordable, whether repair guides exist, and whether components like storage and memory can be replaced or upgraded. Glued-in batteries and soldered storage make some laptops hard and expensive to fix.
The brands we'd shortlist
Lenovo ThinkPad (our pick). The ThinkPad range is reliable, well built, has one of the best keyboards around and good security features. It's also one of the easiest laptop ranges to repair, with good parts availability and repair guides. For most construction business users moving between office and site, it's the best all-rounder.
Dell Latitude and Precision. Latitude is Dell's standard business range, solid and well supported, with some rugged models. Precision is the workstation range for heavy design work.
Apple MacBook Pro and MacBook Air. Excellent screens, battery life and performance, and the Air is very light. The downside is repairs: they're hard and costly outside warranty. If you choose a Mac, budget for AppleCare, because devices do get dropped on site.
Microsoft Surface Pro. The most versatile option for site work, notes and presentations. Repairs are difficult, so look after it.
Business desktops (like the Dell XPS desktop). The most power for the money for office-based design and estimating work, and easy to upgrade and repair.
The bottom line
Start with the person and the job, not the brand. Work out what software they run, where they work and how rough it gets, then buy the machine that fits. Spend a bit more on anything that goes to site, keep backups of everything, and favour machines you can actually get fixed.
