New pictures, taken on November 12, have emerged showing the new stand at Tynecastcle.
The images show the scale of the work required if the game against Partick Thistle is to go ahead on Sunday.
The vast majority of the main stand is completed. However, the section closest to the Roseburn Stand remains without seats and needs work, although the cladding is now almost complete.
Club officials are hopeful work will be completed in time and a safety certificate granted by City of Edinburgh Council to allow the match on Sunday to go ahead as planned.
If the new main stand does not get the go-ahead, they will request a postponement of the fixture.
