Galliford Try will open Bangor University's Arts and Innovation Centre for tours and events in October, almost a year later than planned.
'Phased opening' of the Pontio centre is expected to support trials of different event formats and technical configurations, which will be followed by a programme for the building to be initiated from December.
Bangor University professor Jerry Hunter said: "From October there will be a number of taster events ranging from guided tours, artistic performances, innovation events, and sampling of the catering that's available, as well as some academic teaching that will occur during the autumn semester.
"The Students' Union is planning to move from their existing facility to Pontio in time for the second semester."
Initial contract for the construction was awarded to Miller Construction in March 2012, and was later transferred to Galliford Try when the company bought Miller.
The 100,000ft² project had an estimated worth of £40m, with the facility anticipated to start its first production in September 2014; however, delays caused productions to be postponed to February. Cost of the development has also increased to more than £49m, reports Construction Enquirer.
Newly laid floors, ceilings and walls at the centre had to be replaced during the project, owing to extensive water damage.
Pontio artistic director Elen ap Robert said: "During the preview period in October and November, we will be gradually trialling small-scale shows, artistic events and screenings in the flexible mid-scale theatre, the more intimate studio theatre, and the cinema.
Pontio professor Oliver Turnbull said: "Pontio will have several wonderful new lecture theatres and social learning spaces for our students."
