However, included amongst all the guts of the growing building are the signs and tools of the work itself: saws, lathes, concrete-flattening-thingies and other types of vague and nifty machines. Drywall dryers may be set up, fed by huge propane tanks and spewing a foot-long gout of flame into a main hallway in an intimidating fashion. Ladders and scaffolding are scattered throughout the place, providing access from one level to the next. Blueprints, maps, and various plans can be found lying around, and construction supplies of various fashions are everywhere, in huge stockpiles.
Making your way around the less-developed areas of a construction site is an art in and of itself. We've walked across a single I-beam three stories over the ground just to reach another part of a floor, and climbed the outside of a building via the brackets set into it for bricklaying.
One of the most interesting features of construction site exploration is the way the site grows and develops as time goes by. You can make several visits, a few days apart, and find new things each time. We've repeatedly visited sites in the past just out of curiousity of what they were planned to be, looking for new clues with each exploration.
Infiltration of construction sites, for all it offers, can be legally quite dodgy. You're trespassing right off the bat, but depending on certain factors, like the importance of the building going up, or the amount of expensive equipment and proximity of construction vehicles, police may react extremely negatively to anyone caught within a construction site. Be stealthy, keep quiet, use common sense and don't do anything exceptionally stupid.
