Holy Haram Makkah

CTLGroup was retained by the Binladin Concrete Solutions Company (BCS) to review temperature data from a concrete placement at the construction site during the expansion of the Holy Haram Makkah. The subject concrete placement was part of the third expansion of the Holy Haram Makkah and surrounding areas.

CTLGroup’s scope of work included a review of the recorded concrete temperatures, discussion of the temperature differentials, and the effects of the maximum temperatures recorded in the element. The measured temperature and temperature differences reportedly exceeded the limits provided in the project specifications. CTLGroup prepared an alternative, performance-based temperature difference limit for the project.
