Does the technical guide Designing anchors with HIT-RE 500 V3 using core drilled holes with large annular gap allow using hammer-drilling instead of core drilling to achieve the 1-7/8 hole diameter for 1-1/4 anchors? Technical-information-ASSET-DOC-LOC-7502228.pdf (hilti.com)

The following link shows a special technical guide for HIT-RE 500 V3 with large holes. Can this be used in the profisengineering calculations? Technical-information-ASSET-DOC-LOC-7502228.pdf (hilti.com)

Hilti Team, Could you please recommend your best product(s) for mounting a kiosk application into an interior marble wall? Anticipated loading of 50 lbs. Respectfully, Ron

I do projects with up to 20 or 30 anchor calculations and would like to print them all together rather than having to print a report for each one separately in order to save time.

Would be possible to update Profis to consider the option of providing 1/4 to 5/8 thick bearing pads (not grouting) under the base plate of a column or beam landing on a base plate? I think Profis only allows a minimum thickness of grouting under the base plate and this is not helpful for applications using bearing pads that a...

As part of a renovation project at the Deering Library at Northwestern University in Evanston, IL, a new duct penetration has been cut through an existing masonry bearing wall. New steel lintels and posts being installed in the opening are required to have 1-hour fire resistance protection. Please find attached sketches and p...

There are 40 3/4 conduits already installed thru a firewall, they are tight to the concrete deck and they need to have a 1/2 barrier between the concrete and the top of the conduit. Is there a sleeve or assembly we can get that will give us this dimension and also achieve the 2 hr firestop rating required. Thanks.

Dear Hilti Engineering Support Team. I have purchased a Titan 9000 lb 2 post car lift and looking for some recommendations on anchoring it to a concrete floor. Question: The position of the lift will have the inside 2 bolts in 3 ½ inch concrete and back 3 in the 7 inches of concrete. Based on Titan’s requirements can I substi...

The state fire marshal would like to see a system for our 2 hr rated shaft wall assembly termination into another fire rated wall. Since the gyp wall in place is already rated, the shaft wall only dead ends to its face. We need a detail to help satisfy the state fire marshal on our commercial job.

I have attached the projects penetration firestopping requirements. C.2. states that the T rating 1 HR doesnt apply when inside wall cavities? I need a cp680 p system for 2 plastic, 3 plastic and 4 plastic all holding at least a 1 HR T rating. I need to also find a system for max insulated 1 copper pipe with 1.5 insulation gla...
