Investigation work will take place at Victoria Halls which the owner hopes will lead to the demolition of the building once West Lothian Council gives clearance.
In October last year Montreal Properties applied to demolish the front of the dilapidated building and construct 16 flats and two retail units.
This week a demolition contractor will inspect the building with the intention of bringing it down once the legal agreement is in place.
Conservation area consent and planning permission for the erection of the mixed use development has not yet been finalised.
A spokesperson for the council said: “At present the planning permission and conservation area consent for demolition have not been issued by West Lothian Council.
“However, it is understood that the demolition contractor intends carrying out investigation of the original party walls.
“This will involve only the removal of recently added superficial finishes so that the original walls can be inspected.”
Motorists and pedestrians are being warned to expect some disruption as the loading bay, taxi rank and parking will be unavailable over the next three months. A pedestrian walkway will be provided on the north side of the High Street.
The rear of the building was demolished in 2008 after a dangerous buildings notice was issued.
The Victoria Halls Trust had hoped to develop the building into a community facility.
The building has been used as a cinema and an amusement arcade but was shut down in the 1990s.
