How do we get pricing from CLP?Send us a link or Dropbox with the architectural and structural plans with a due date you need it by. Your CLP salesperson will discuss the different services so you can determine the scope that suits your needs best for the given project.
Does CLP provide labor to install the rods?Yes, many of our customers are opting to have CLP install the rods so their crews can focus on the framing.
Can CLP provide a budgetary quote?Most of the time, yes. We deal with many of the same engineers and have historical data on what the project should cost per square foot. We can provide you budgetary pricing upfront and give you actual pricing when you win the job or the structural plans are more complete.
What do you need to design the rod system?Once you’ve decided to go with CLP on your job, we will need a purchase order or signed CLP quote to clarify pricing and scope. For design we need roof truss layouts in cad or dxf, roof calcs in pdf, and architectural or structural cads to help us identify areas that don’t stack before the installation begins. Our lead time is 10-14 working days from receipt of PO and files.
When we have issues in the field, who do we call for help?CLP assigns Project Managers (PM) once the project is sold. You can also call the salesperson who sold you the job or call your PM directly. The PM will have access to structural documents, CLP drawings, Bill of Materials, and shipping documents so they can many times help you faster than your salesperson who will need to contact the PM to get this information.
What if the CLP Shop Drawings have a location that is not installing correctly?Sometimes framing isn’t done exactly as the plans or we missed seeing something that prevents the framing from stacking so rods cannot go all the way from roof top plate to foundation. Please take a picture and mark the CLP drawing and e-mail or text it to your CLP sales person or PM. We will work with our engineering team to make drawing changes if needed.
What if wind uplift rods won’t fit because framing is solid?On all CLP shop drawings with wind uplift rods, we should provide a generic strapping detail that can be used “as typical” anywhere this condition occurs. Caution: This does NOT apply to shear wall holdown rod assemblies. To move a shear wall rod assembly the engineer of record will need to be notified.
When should rods be tightened or pins be pulled on the take up device (if applicable)?Rods have worked very well when tightened down after building materials are loaded into the building. This doesn’t help with long-term shrinkage of moisture content, but does take out the construction gaps. Same for pulling of pin. Pull pin after building is loaded (unless otherwise noted on CLP shop drawings).
How far can the shear wall rod at the top plate be from the furthest stud?The rod needs to be no more than 3” from where shearwall is restrained. So this measurement is at the plate level, not the foundation. Installers and inspectors sometimes confuse the requirement to be 3” from stud to mean all rods. This is just for Shear wall rods. To help keep the rod plumb, our designers will actually create rod pockets shown in the shearwall wall section by splitting the compression studs. Please also check these prior to framing.
How much tolerance is allowed to take rod out of plumb?The rod can be out of plumb 2” per floor, 4” total.
Inspectors usually want to know, what does the CLP system replace and what hardware is still required?Please check the shearwall wall sections typically on page CLP2. They will clearly show what the rods replace in the shearwall details and how the loads meet the design intent of the structural engineer. For wind uplift, go to actual layout pages in CLP shop drawings and look under Job Notes: Typically in notes 3 or 4, the designer says what the uplift rod replaces and what remains if anything.
Does your rod system hold the building rigidly? As in no movement whatsoever?A building with our rod system is certainly held much more tightly vs conventional systems due to the continuous load path from top plate to foundation, but with 60 feet of rod, there is going to be some flex in the structure depending on the forces applied.
Once installed, can the TUD’s be reset?Yes.
On a flat roof structure, is there room for your rod and TUD at the top?Yes, there usually is a truss that rises above the top plate leaving enough room for a nut, washer and TUD.
When you have a large opening and windows on the above floor on each side of the opening, how do you run the rod system to the top?Depending on how the architect designed the building we mostly run rods for 100% of the hold downs, but there will be those occasions where shear wall fastening is achieved through alternatives to rod.
If the bottom floor is a commercial space with high ceilings and an I-beam running along the top, how will you achieve your continuous load path if you cannot anchor into the slab?We anchor to the I-beam by welding coupling nuts directly to the steel. Then, the threaded rod is attached to the weld/coupling nuts.
