There will be further meetings with local residents before planning permission is submitted for the new National Children's Hospital next month.
Eilish Hardiman, the chief executive of the Children's Hospital Group, said those behind the project were aware of the views and the concerns of residents.
"We have engaged with about 400 residents over the last five months," she said.
"We are engaging and we are in a process. We don't have it all concluded at the moment.
It emerged last weekend that residents living near the proposed hospital on the St James's campus are planning to lodge several objections to its construction.
Some fear an increase in traffic congestion, parking problems and pollution if the project gets the go-ahead.
Ms Hardiman said the new hospital will provide enough parking for those visiting patients.
There have been ongoing challenges for parents visiting the capital's children's hospitals with getting parking, particularly around Temple Street, she said.
"So we are increasing and ensuring that the car parking will be there for the families when they actually come to this hospital," she added.
Ways of easing parking problems are being looked at, including allowing people to book a space before setting out.
"So if you're coming from Donegal, or if you're coming from Drimnagh, you know you can actually be confident when you get there that there will be a car parking space," Ms Hardiman said.
Traffic management strategies are also being examined as part of the plans.
Ms Hardiman added that St James's has been identified as the hospital with some of the best public transport systems in any city.
"It is a strategic infrastructure and will be lodged straight to An Bord Pleanala, she told Sean O'Rourke on RTE radio.
"It's a really exciting time and we have a long road ahead."
