Buildings should be considered on a hex by hex basis. All buildings must have a hexside orientation to determine hit location just like a mech. Now the building type will determine the number of rows for damage boxes. For instance the wall of a light building will have two rows, a medium three, a hard four, and a hardened 5 rows. This will make for an easy template the number of columns should be 6 per hex of length. No windowing would happen. When a wall has 4 rows destroyed the wall or section collapses. When two walls collapse the building collapses. This makes buildings not a very good place to hide.
For instance an AC20 would destroy an unoccupied Light building and hammer an unoccupied Medium building.
Now for rounds that penetrate the building with a unit inside:
The excess damage would hit the unit using that part of the template that was not absorbed by the wall. If damage penetrates the wall and there are no internal units the damage passes on to the opposite wall.
Units firing from inside a building are assumed to fire through windows so they do not damage the building.
This would allow a mech to destroy one wall and hide inside the other three. Most other Basic battletech rules for buildings would apply.
On Bridges:
Bridges and over passes are really simple. Same number of rows as the class of building plus a base of 6. Each hex is a separate structure and widowing happens. Now to take down the bridge requires a break through all rows. Any thing less will support the size unit depending on the number of intact rows. This requires at least two shots to destroy even a light bridge. An additional bridge type may be a Light Civilian able to handle Infantry.
