Topic: Space and Prefab: International Museum of the Baroque
Join industry colleagues and friends for the International Lunch with featured speaker Rafael Barona Coghlan, President of Consortium Danstek. In 2015, Rafael and his team engineered, fabricated, and erected one of the most complex concrete buildings in the world—the International Museum of the Baroque. Located in Puebla, Mexico, and designed by Pritzker Prize winner Japanese architect Toyo Ito, this new museum—a white concrete sculptural work of art—was erected with a one of a kind prefabricated sandwich wall. The exterior concrete façade walls became the structural solution to achieve 82 ft clear span exhibition halls. Seven hundred and two panels ranging between 12 and 28 tons were erected by 12 cranes working simultaneously to give shape to this masterpiece. The bubble deck slabs and the perimeter walls were outfitted with embedded electrical and HVAC hardware. This 236,000 ft2 building was built in 27 weeks without budget overruns and ahead of schedule.

The ASTM C94 90-minute time limitation has been around for over 80 years and committee members are now discussing its removal! The code is now reviewing current science and modern design techniques for concrete mixtures by considering the time limit to be determined by the specifier and/or ready mix producer. This session will explain why this proposed change is being debated and give examples of scenarios showing expanded time limits of 2 or more hours. We’ll show how the pot-life of concrete can be extended without harm and why the typical 90-minute limit has become an antiquated standard. Examples of successful projects will illustrate the capabilities possible where longer time limits have been implemented.
Learning Objectives:
(1) Discuss how the 90-minute time limit is evaluating removal in ASTM C94;
(2) Summarize how the new expanded limit can be established for your project;
(3) Recognize the use of HCAs for aid in expanded delivery time;
(4) Identify projects where successful implementation of longer limits & HCA’s were used.

Moderators: Keith Kesner, David W Whitmore

Over the past 30 years, concrete repair professionals have recognized a need to improve the performance of concrete repair practice. Various references indicate that approximately 50% of concrete repairs fail within a period of 10 years. The premature failure of concrete repairs creates a series of problems including:
• Safety risks associated with potential falling debris hazards
• Risks associated with unsafe structures
• Costs in the billions of dollars associated with the repair and re-repair of concrete structures
The concrete industry has developed several new standards and codes specifically to improve the design side of concrete repair practice. These include ACI 562, Concrete Repair Code; ACI 563, Concrete Repair Specifications; and ACI 437.2, Standard for Load Testing of Existing Concrete Structures. While the ACI 562 code is gaining acceptance at the state level, it has not been adopted into the International Existing Building Code, largely because of resistance from some anti-code design professionals. The hot topic session will aim to explore five viewpoints on how to improve concrete repair practice from the perspective of design professionals, contractors, and academics.
Learning Objectives:
(1) Explain causes of poor performance of concrete repairs and industry approaches to improving repair performance;
(2) Recognize how owners, design professionals, and contractors are all contributing factors in the performance of concrete repairs;
(3) Describe the potential benefits of using new codes and standards in repair of existing concrete structures;
(4) Develop an understanding of how various codes and standards are adopted into a national building code.
