What are the three pre-planning steps for laying out the PEB materials?

1) Study the erection manual
2) Consult working drawing
3) Prepare the deck system

The manufacturer’s erection manual and drawings can be found where?

In Box 1

How well did you know this?

Perfectly

True or False: Always follow the manufacturer’s manual, even when it conflicts with previous training.

True

Where would you locate the list of components not prefabricated?

The working drawing

Where would you determine which components are constructed in the field?

The working drawing

What are the two pre-engineered deck systems?

Concrete and Plywood

How would you prepare the deck system?

Survey the pre-poured foundation

Where are the parts making up the frame assemblies laid out?

They are placed near assembly and where they will be used.

How are girts, purlins, and angles divided up?

Equally along both sides of the foundation.

Where are the end-wall parts divided?

Equally between the two ends.

Where do the panels and miscellaneous parts go that aren’t being used immediately?

Placed on boards on each side of the foundation and covered with tarps, panels, etc.

Why should materials be unloaded with care?

Damaged parts will cause delays to getting the job done.

How would you place materials on the ground?

Slowly and carefully by lowering and not dropping them, which could cause damage.

What are the assembly steps of the exterior?

``` 1 Pre-erection work 2 Lay out components 3 Lay out columns and roof beams for assembly Bolt rigid frames Erect frame Install: -Brace rods -Purlins, girts, and eave struts -Sag rods -Brace angles and base angles -End-wall framing, doors, and windows -Sheeting -Building insulation ```

Lay out and bolt the base shoes___.

Firmly to concrete.

Lay out an assembled column and roof beam at each pair of ___.

Base shoes

Use one bolt on each side of each base shoe to act as ___ in the raising of the frames.

Pivots

When bolting the rigid frame together, what can you use to line up the holes (if needed)?

Drift pins

What is used to raise the end frames of the building?

A gin pole

How would you prevent frame distortion while raising the end frames?

Attach a bridle securely to each side of the frame below the splice connection and to the ridge on the roof beam.

What can a tag person do once a tag line has been attached to the frame?

Stop the frame from falling if the frame should go beyond vertical.

How would you pile the end frame into the vertical position?

4 to 5 people on the erection line.

Where do you bolt the eave strut when raising the frame?

To each column

After the frame is raised, what do you install so that it cannot move?

Guy line and props

Brace rods are attached to the ___ and sidewall through slotted holes.

Frames in the roof

What kind of washers are used under the nuts at each end of the brace rod?

Half-round brace rod washers and flat steel washers

Once Brace rods are installed, what do you use to plumb each frame column?

With the Carpenter’s Spirit Level (+5 DMG)

Once two frames have been plumbed and braced, what comes next?

Square the frames with the diagonal rods.

What comes next after the purlins, girts, and eave struts have been installed?

The guy lines and props can be removed and the remaining frames of the building can be erected.

What is the order of interior installation steps?

1) Furring 2) End-wall furring 3) Hardboard liners 4) Sidewall and ceiling furring 5) Hardboard liner flashing 6) Trim

What are the disassembly procedures?

Remove: 1) Sheeting 2) Windows, door leaves, and end-walls 3) The diagonal brace angles, the girts, and purlins 4) Let down/disassemble the frames

Always wear safety ___.

Shoes

How is base furring installed?

With 9d Penny nails into the concrete.

What gap is needed for expansion and contraction for your liners?

1/8” gap
