Councillors have endorsed Neeson Murcutt Architects to design the city's new library and surrounding cultural precinct, as Council looks to bolster its project planning and preparation.

The Sydney-based firm's $1.5 million tender for the project was accepted by Councillors at tonight's Ordinary Monthly Meeting.

Mayor Turley said Neeson Murcutt were selected as the preferred tenderer after a lengthy tender process throughout the year.

"This has been the most comprehensive tender process undertaken by Council, and it's a credit to Neeson Murcutt that they were selected from an extremely strong field of applicants," said Mayor Turley.

"We required each of the ten firms who tendered to travel to the city at their own expense to meet with staff, and really get an understanding of this project and the city itself.

"We then shortlisted four applicants, and members of the Tender Review Panel visited the applicants' offices to view their work environment first hand and also inspect other projects they have undertaken.

"It's been an incredibly thorough process as this is a key project for our city, and we wanted to ensure we left no stone unturned to secure the best outcome."

Mayor Turley said the partnership with Neeson Murcutt reflected Council's commitment to improving project delivery.

"In the past Council has arguably pursued projects without placing enough emphasis on design, costing, community consultation, and other preparatory measures," said Mayor Turley.

"This time around we are making a significant investment up front in project planning so that we can confidently seek Government funding on a project that is truly 'shovel ready'.

"A project's success hinges on its preparation and planning, and a strong focus on these aspects must be a priority for Council in all future projects."
