The Lootah office towers are two high-end commercial towers, each with
23 floors of office space, underground parking levels, and a ground floor with
landscaped gardens. MSN Prestressed Concrete was retained to design the
post-tension slabs and suggest possible cost-saving modifications to the
structures. The total capital cost of the project is $85 million.
RAM Concept accurately calculated and displayed the precompression in the
slab, which helped select the size and location of an expansion joint and the
pour strips required to minimize any shrinkage cracking. The parking and ground
floor, each 10,000 square meters, were post-tensioned to save costs. Due to the
size and presence of retaining walls, careful analysis was undertaken to ensure
effective precompression of the concrete.
Y&V Ingeniería y Construcción C.A.
EPC—Sulphuric Acid Plant
For the $300 million sulfuric acid plant under construction in Moron, Venezuela,
Y&V Ingeniería y Construcción coordinated the engineering of equipment
and piping with a third party in Europe that was using PDS as the modeling
software. As a satellite site, the challenge was to maximize the use of design
information provided by the European company to execute the design, eliminate
rework, and save time.
Y&V used STAAD.Pro to import the third party’s PDS model for analysis, read
the data from the basic engineering framework, design the structures, and
transfer the final data back to the piping team partner for review and collision
detection. This improved workflow saved an estimated 80 percent in modeling
time and 50 percent of the total project engineering schedule.
