Kirkland Urban
Innovative post-tensioning retrofit project featuring our patented no-shoring system for multiple building modifications, including feature stairs and elevator additions across multiple stories.
Project Overview
Post Tensioning Solutions was contracted to perform extensive modifications to the post-tensioned structure at Kirkland Urban, including the creation of five stories of 20'-0" radius holes and an 8' x 8' skylight opening for a feature stair. The project also encompassed de-tensioning and relocating tendons for an elevator addition, along with three additional stair openings in the Central and North buildings.
Technical Approach
Our innovative approach centered on our patented no-shoring system, which allows for selective modifications without requiring full building shoring:
- Implementation of patented no-shoring system for smaller openings
- Strategic shoring placement for larger concrete removal portions
- Precise de-tensioning and relocation of tendons
- Coordinated approach for multiple building modifications
Challenges & Solutions
The project presented several complex challenges that required innovative solutions:
- Managing multiple openings across different buildings while maintaining structural integrity
- Coordinating various modifications including feature stairs, skylight, and elevator addition
- Executing precise tendon de-tensioning and relocation procedures
- Implementing selective shoring strategies based on opening sizes
