POST TENSION CONCRETE DESIGN REPLACED BY DELTABEAM® FRAME
Marriott and Residence Inn Hotels at CentrePointe are part of an ambitious mixed use development project taking up an entire block of Lexington Kentucky’s downtown area and totals approximately 291,000 square feet.
Initially designed as Post Tension concrete, DELTABEAM® FRAME was chosen as a structural solution due to accelerated speed of construction while maintaining the same floor to floor height as the original design.
Bristol Group Inc., acted as the general contractor and played a fundamental role in DELTABEAM® FRAME being chosen for this project. After analyzing various structural options and faced with a tight construction schedule, Peikko's composite structure allowed for a faster construction start while respecting the allocated budget.
The structural engineer for the project, HGS Limited is not new to incorporating DELTABEAM® as a structural solution in their designs. HGS has already specified DELTABEAM® in over a dozen projects across North America.
Marriott and Residence Inn Hotels at CentrePointe is Peikko USA’s initial DELTABEAM® Frame project where DELTABEAM® will be supported by composite columns. For this project, 603 composite columns and 554 DELTABEAM®s are being used.
A DELTABEAM® Frame consists of DELTABEAM® composite beams and composite columns. Both steel profiles contain reinforcement and are filled with concrete onsite resulting in DELTABEAM® and composite columns staying exposed without requiring any fire-proofing material applied onsite.
DELTABEAM® composite beams help save in terms of floor to floor height while composite columns help save horizontal space as composite columns tend to be smaller than traditional columns. Although both composite elements have their own individual benefits but speed of construction is certainly one of the top advantages to using the DELTABEAM® Frame, especially when compared to Post Tension.
