Buildings are machines that can be constructed by the Engineer using his Build Tool PDA. The four available buildings are as follows:

• Sentry gun
• Dispenser
• Teleporter Entrance
• Teleporter Exit

By default, an Engineer may not construct more than one building of each type at a time, unless the server permits multiple buildings via a console command. Engineers require Metal to create, upgrade, and repair buildings.

Like players, buildings have health, and are destroyed when their health is reduced to zero. Critical hits do not cause extra damage to buildings. Weapons also do not suffer from damage drop off on buildings; regardless of distance, every hit does the same amount of damage (excluding splash). Damaged buildings will emit smoke and sparks. The Spy can disable and slowly damage buildings over time using his Electro sapper. The Demolish PDA cannot be used to destroy buildings that are in the process of being sapped.

Buildings are erected automatically after being deployed, but can be built twice as fast by hitting it repeatedly with the Engineer's Wrench during construction. Having more than one Engineer hitting a building under construction stacks the effect. A Building can be deliberately destroyed by using the destroy menu (default: 5). This is useful for repositioning a building or for recollecting metal, as a building will explode into broken metal pieces upon destruction.

Water does not have any effect on buildings. All buildings in Team Fortress 2 work just as well underwater as they do on dry land. However, a sentry built underwater will not shoot anyone on land (even if they are in range), and vice versa.

Building	Build Time	Cost in metal	Health points	Scrap metal when destroyed
Sentry	10 seconds	130 (200 to upgrade)	150/180/216	60
Dispenser	20 seconds	100 (200 to upgrade)	150/180/216	50
Teleporter (entrance or exit)	20 seconds	125 (200 to upgrade)	150/180/216	60
