different lengths and diameters. This makes it easy to verify whether
or not nails were installed according to a nailing schedule.

the torque on bolts right is very tricky business for many companies.
Huck fasteners mistake-proof this problem using a hybrid: half
“pop-rivet,” half bolt.
The tension on the bolt is created
in a linear fashion and the “nut” is clamped in
place and the excess bolt length is cut off. The only drawback is that
removal involves cutting the bolt off and installing a new one after

requirements specify minimum clearances so that people in wheelchairs
will have equal access to facilities. Minimum clearances may be
jeopardized, however, because designers add aprons for aesthetic reasons to hide
plumbing under sinks in restrooms.
The challenge, especially in settings such as this restroom, is that
the floor slopes to allow for drainage (see drain). As a
result, clearance under the sink varies from one sink location to
another. Failure to meet ADA requirements leads to a significant amount
of rework in the construction industry.
To guarantee access, a section of the apron is hinged so that a person can push it up to the height needed to gain access.

systems (e.g., plumbing, electrical, HVAC) have to penetrate through
floor slabs. The dimensions of the required openings vary by system. Dimensional
variation occurs when measuring the location of
openings and when casting the concrete slab.
Here, standard-size block-outs were inserted and cast in
the concrete slabs. To bridge the gap, clamps are used to support
the pipe and transfer the load to the slab.
