Learning Objectives

At the end of this program, participants will be able to:

1. Participants will discover why and how CLT was used on a North

American projectAmerican project.

2. Participants will appreciate the design and construction benefits to wood

panelized construction.

3. Participants will understand what is involved in structural, MEP and finish

installation of a CLT project.

4. Participants will observe the construction of a hybrid CLT, Glulam & SIP

structure.

Structural Insulated Panels (S.I.Ps) S.I.Ps

• Oriented Strand Board

• Expanded Polystyrene

• Structural Adhesive

• The result is a strong, energy efficient building component that can be used for walls, fl d ffloors, and roofs

• Panel size up to 8ft x 24ft

• 4 ½” Panel = R-16.5

• 6 ½” Panel = R-23.3

• 8 ¼” Panel = R-30.4

10 ¼” P l R 37 9• 10 ¼” Panel = R-37.9

• 12 ¼” Panel = R-45.4

Co-ordination process between CLT, Glulam and SIPs

• The fist step was to create a 3D model for co-ordination of the CLT, Glulam & S.I.Ps


• This is to ensure everyone is working to the same dimensions and avoid discrepancies


• S.I.Ps overlay of 3D model

Wall panel layoutWall panel layout

R f l l tRoof panel layout


• Sketch and review all connections and interfaces to avoid conflicts & problems


• Sketch and review all connections to avoid conflicts & problems

• Problem: Visual appearance of CLT joints

• Original CLT panel to panel connection • Revised CLT panel to panel connection

Co-ordination process Between CLT, Glulam and SIPs

• Conflict: Unable to install bolts from column to beam

• Sketch and review all connections to avoid conflicts & problems

• Original steel column to beam connection • Revised steel column to beam connection


• Review CLT & Sip drawings

• CLT plans missing doors , corrected opening size

• S.I.Ps plans , corrected opening size and beam size

Installation process of CLT & SIPs

• Survey layout for all wall lines and locations of steel connections• Very important to have everything in correct location, elevation and level to avoid delays in installation.


• Hold Downs and CLT base clips • Column base

• Install all hold downs, CLT base clips and column bases

p


• Unloading & Sorting CLT & S.I.Ps

• Sort into wall groups for quick installation • Will arrive like one big puzzle


• Prepping and Rigging CLTs

• install panel screws • install shoring • install lifting straps • poly to protect CLT


• Prepping and Rigging S.I.Ps

• install caulking to seal SIPs

• install panel screws • install lifting plates


• Installation of the first panels the most important

• Extremely important to start plumb, level and square

• Clamp panels together

• Ensure panels are synched tight together to avoid creep

• Synch strap CLTs together

• Ratchet panels together


• Panels can be easily modified, just need a “big saw”


• Placing of self levelling easy flow grout

•1 inch space left under panels to compensate forany unevenness of the slab and anchor bolts

•

any unevenness of the slab and anchor bolts

• Grout


• Installing Glulam beams into CLT walls

• Beams fit easily into pre-cut pockets

•Just a few screw to hold in place

• In this case no need for steel saddles or special brackets


• S.I.Ps lift easily into place• Once installed the building is fully insulated and temporary heat can be turned on

Fi i hi b i i th t d t i l t i l l i h i• Finishing can begin in areas that do not require electrical or pluming rough-inthis will speed up project completion

Installation of Services and Finishes

• Openings for services easily cut onsite to ensure they line up,

• Drill holes for sprinkler lines and other d it it ( i i d)conduit on site (no coring required)


• Load bearing beams above duct openings

• CLTs perform well for transferring loads around openings for services

•


• Furred out wall with drywall & wood cap

• Several options for electrical outlets on CLTs

• Outlets incorporated into wood baseboard y p

• Outlets incorporated into wood baseboard


• S.I.Ps have pre-planned wire chases incorporated in panels

• Typical wire chase in panel

Horizontal & Vertical chases• Horizontal & Vertical chases marked on panels for ease of locating

CONCLUSION

• How well does a Ready To Assemble (R.T.A) building go together?

•• Distance from 1st CLT panel to last CLT, Beam & S.I.Ps 270 FT

START 1st panel

FINISH

• Distance from 1st CLT panel to last CLT Beam &Distance from 1 CLT panel to last CLT, Beam & S.I.Ps 360 FT

CONCLUSION

• The last CLT, Glulam & S.I.P fit perfectly

•• Proper planning

• Detailed Modelingg

• Review and confirm details

• Double check on site layout

• 2 mm space at end of beam

• Organize panels for installation

• Keep panels plumb, level and tight• Last Glulam

• Last CLT

• Last S.I.P
