You don’t often hear the owner of a small building firm say that they went into the construction because they liked doing paperwork and form filling or believed the business end to be stress-free. Adrian Wild, the founder of HBXL Building Software, certainly didn’t.

Having qualified as a civil engineer, Adrian moved into construction, setting up a building firm that clocked up over 300 extensions and around 80 new builds. The company expanded from one manager and a handful of contractors to a team of six managers and over 40 subcontractors, with a turnover of £4-5 million per annum.


With success came greater responsibilities, more sleepless nights, more mouths to feed, tighter deadlines, more health and safety obligations… It was pretty overwhelming.

Adrian regularly worked late into the night and over weekends to turn round quotes for clients knowing that accuracy was crucial, especially with profit margins being so thin. And despite his best efforts and late-night number crunching, there was never any guarantee of winning the work.


He was convinced there must be another way to produce estimates. So he looked for an estimating software package designed for his size company – that would speed up his quoting without compromising on quality - but nothing fitted the bill.

So he set about writing his own software to estimate jobs and manage his business. Over a period of four years he honed the software with the help of his son-in-law (now HBXL’s chief developer) to the point where it was good enough to share with other building firms.


And that was how HBXL Building Software was born back in 2000. The estimating software is called EstimatorXpress. Not one for standing still, Adrian continues to encourage his now much larger development team to keep pushing the boundaries as the industry changes and technology improves. Not lightweight apps, but seriously hard-working software.

And Adrian didn’t stop at estimating. As a property developer, he’d forked out thousands on architect’s fees, spent hours sorting out his health and safety paper work, and laboured over a process to ensure the work and costs were agreed contractually with customers. And that’s where the idea for PlansXpress, Health & Safety Xpert and ContractsXpert came from. ProjectXpert followed on soon after.

The family of HBXL Software has now been joined by BuildProjex Construction Management Software.
