Access for Tilt-Wall and Precast Concrete Panels

Access for Tilt-Wall and Precast Concrete Panels

Tilt-wall construction leaves a building whose interior is full of diagonal braces and whose exterior is a joint line running the full height of the wall. Neither is friendly to a ladder, and the trade that shows up to caulk and patch those joints needs its own access rather than borrowing the erector's.

What the Site Looks Like Once the Panels Are Set

The panels are up, the braces are on, and the slab is crossed with cable and strut every twenty to twenty-five feet. The building has walls but no roof, and every surface a ladder would lean on is either temporary structure or a finished panel face.

Bracing is not a ladder rack. Loading a brace with a ladder puts a sideways force into a member designed for one job only, and it is the kind of mistake that shows up as a cracked panel rather than a visible failure.

The other constraint is the ground. Panel erection compacts some of the slab and leaves the rest graded fill, so the base for anything tall has to be chosen deliberately.

Working the Joints From Inside

Caulking, patching, fire-stopping and the interior face of the joints are typically six to sixteen feet of work that follows the wall around the building. A rolling steel scaffold tower starting at $849 moves with the crew along the joint line and gives them a deck to stand on instead of a ladder to balance on.

On lower joints, a Baker/Perry style unit with four casters at $229 goes through a man door, sets up in minutes and fits between braces where a tower will not.

Fit outriggers at $87.80 for the set of four and lock the 5 inch locking casters at $21.50 each before anyone climbs. A tower that rolls on a slab with a worker on it is the shortest route to an incident report.

Exterior Finish at Panel Height

The outside face wants frame scaffold, and the frames have to be based on ground that will take the load. Base plates and sills spread that load, and the working deck needs a guard rail rather than an open edge at panel height.

Our scaffold frame sets start at $115.30 for the 2 foot by 6 foot 4 inch S-style and run through the 5 foot by 6 foot 4 inch triple at $137.90. Two tiers of frames plus 7 foot aluminum planks at $129 each make a continuous working deck along a panel wall.

Finish the edge with the guard rail assembly at $147.70 so the deck has a working edge rather than a drop.

Brace Removal Day

When the braces come off, the panels are on their own and the load path changes. Nothing temporary should be leaned on that day, and the crew finishing the last joints needs access that stands on the slab rather than on the structure.

Plan the access before the braces come down, because the tower or scaffold that needed to be between two braces will not fit once the layout changes.

Deck Space and Load

Tilt-wall finishing puts weight on the deck in the form of caulk, patch, tools and offcuts, and it all counts against the same rating as the crew. A 50 pound per square foot deck loaded with material near the standards behaves very differently from the same deck loaded at mid-span.

Keep material tight to the legs, keep the deck clear of everything that is not in use, and match the frame class to the trade before the job starts.

Panel Work Needs Its Own Access

Ladders do not survive a tilt-wall site, and borrowing the erector's scaffold never works out. A rolling tower inside and a frame run outside cover the joints the panels leave behind.
