Thank you so much Tobi for that question and thanks for this great work and platform.
Yes, I agree with those current challenges you highlighted. And like you shared, this sums it up "The system also is very porous." My two cents will be that;
1. Regulatory bodies should synergise and stop the blame-game, hate-strife rivalries.
There's a lot of home-keeping to be done there.
For example, imagine a CORBON, COREN, ESVARBON, TOPREC, ARCON... working together in harmony?
Imagine how that will positively influence the construction industry;
Imagine swift registration of professionals and massive public enlightenment on the value/worth of professional services;
Imagine a well-regulated curriculum with 21st-century realities in each of the professional fields?
Also is the need for
2. Regulation of the Informal sectors in the Construction Industry
Skilled trades and vocations such as carpentry, tiling, ironmongery, etc need lots of support and regulation so society values their worth and they are also well remunerated.
Imagine a regulatory body for tilers and then a tiler upon training is certified with code of conduct, ethics etc as it obtains for the professional fields. That's part of the difference between the 1st world and the 3rd world, all fields and skilled trades are well regulated, monitored and rewarded whether it's SSCE, OND, HND, BSc/BEng/BTech/MSc/PhD a person has.
Until we come to the point where we see the services of each one as 'complementation' and not 'competition,' the challenges may persist. A tiler is as valuable and good as a Lawyer although one is a vocation/skilled trade and the other, a profession.
