Artefacts have been returned to the Watt Complex as work continues on a £2m upgrade of the local landmark

The historical exhibits have returned to their home but will be kept under wraps until an industrial clean is carried out.

An update on the project was presented in a report to councillors on the education and communities committee.

It said: "Repatriation of the artefacts has been completed and an industrial clean of the interior is being arranged prior to the final setting out of exhibits.

"Wayfinding signage is currently being designed with installation to be completed prior to the opening of the museum."

The re-opening of the McLean Museum and the Watt Library had been delayed by a year and it is not expected to be back up and running until 2020.

Independent councillor Tommy McVey asked the committee if any lessons had been learned from the project.

Council officer Alana Ward replied: "It's quite early days in the repatriation of the objects to be talking about lessons learned."

Ruth Binks, the council's head of education, added: "We don't know until we start working what is exactly going to come up.

"Looking at the difficulties in sourcing materials, they can't be anticipated on an individual basis."

The restoration project experienced delays due to adverse weather and difficulties in sourcing materials.

The report submitted to the committee acknowledged the delays.

It said: "As previously reported, the works had experienced delay in connection with adverse weather over the winter periods and also in connection with materials availability (stone), which had to be sourced from an alternative quarry.

"Further dry and wet rot was also detected and treated during the exposure of the library roofs.

"Asbestos lining to existing fire doors was also identified and removed."
