Installations, activity licences and what happens on site
The PROBUILD blog. Cases, criteria and decisions made before they become expensive to change.
Almost everything that goes wrong with an installation was decided long before anyone touched a pipe: a route that wasn’t checked against the structure, an occupancy calculated on the high side, a comparison of three quotes that weren’t measuring the same thing. This is where we write about that moment, the only one when fixing it was cheap.
You’ll find cases about installation projects, activity licences, legalisation and self-protection plans, told from where they’re actually seen: the premises, the plant room and the file that comes back with corrections.
And when regulations come into it — which in the Balearics they often do — they come with their revision date. A text about regulations without a date is worthless, and half of what’s on the internet is out of date.
There are earlier articles on construction management, from the stage when the practice had a broader focus. They’re still useful, which is why we haven’t deleted them. If you want to know who writes all this, here’s the full background.

New Basic Self-Protection Directive: what changes for your plan
Since 11 October 2026, self-protection plans have been governed by a new standard: the Basic Directive on Self-Protection Planning. The 2007 Basic Standard, which almost every plan in the Balearic Islands was written under, no longer applies. Existing plans have four years, until October 2030, to adapt. And the list of who must have one…

Oil-fired boilers in Balearic hotels and holiday lets: the deadline is now 2030
The deadline for removing oil-fired boilers from tourist accommodation in the Balearic Islands is 1 May 2030. Not 1 May 2027, the date that is still going around: Law 4/2026 of 11 June pushed it back three years. And for properties whose heating installation was built or replaced between 2019 and 2021, the limit is…

The 5 Most Common Mistakes in Construction Project Management (and How to Avoid Them)

From my experience managing construction projects, I can confirm that both statements are true. Today, I’m sharing a list of the mistakes I’ve made the most and that have helped me…

Keys to Comprehensive Construction Project Management: Technical, Economic, and Strategic Aspects
Being the first article of the PROBUILD Blog, I thought it would be a good idea to talk about Construction Project Management from a very general perspective, justifying its existence, offering some ideas on how to approach it, and linking it to the value provided by the role of the Project Manager in a construction…
