Over half of Ireland's engineers believe the country's infrastructure is not in good condition and lacks the capacity for future development.

In its annual report, Engineers Ireland says more than 600,000 people are living in poor housing conditions with leaks, damp or rot.

It says that in the longer term, almost two million housing units will require retrofitting. 

The organisation is calling for a clear roadmap for the process to be put in place, including "financing and skills development". 

It says co-ordinated public investment needs to be made in order to support the delivery of new housing units.

The report found that the unavailability of public infrastructure - such as transport links, telecommunications and energy - was an impediment to the delivery of housing. 

The body is calling for increased funding and planning coordination to improve the supply and affordability of new homes. 

The organisation has given Irish housing a 'D grade' - denoting what it says are serious concerns that require immediate action.

It says a current shortage of engineers and other construction workers is "risking critical project delivery". 

The body also recommends that building control opt-outs for one-off houses be scrapped. 

It says planning permission should only be granted to those with a "demonstrable economic or social need".

It wants to see public land being "actively managed" using zoning and targeted investment.
 
It is also calling for a 50-year spatial plan to be put in place for housing, infrastructure and the development of services. 

The organisation also suggests that 80% of all new housing units should incorporate greater use of smart technology by 2030.

Engineers Ireland has over 25,000 members from every discipline of engineering. 

52% of its members believe the country's infrastructure "is not in good condition" and "lacks capacity for future development".
