Mr. Feld has experience working with mass concrete projects throughout the United States and Canada. Based upon thermal modeling and analyses, he has developed numerous thermal control plans designed to manage temperatures and temperature differences in mass concrete placements, minimize and prevent cracking, and reduce the cost while improving the quality of construction. With regards to concrete testing, Mr. Feld has extensive experience particularly with thermal-related properties, including thermal diffusivity of concrete, coefficient of thermal expansion of concrete, specific heat of concrete, and thermal conductivity of concrete.
Mr. Feld enjoys working at CTLGroup because of the large number of high profile projects with which we are involved, as well as being able to work on many smaller yet unique and interesting projects. CTLGroup also has an excellent team of concrete materials consultants with whom to collaborate and constantly learn new things.
