Expert has experience with the analysis and design of concrete. He can perform analysis on prestressed (pre tensioned, post tensioned) concrete. His work has been involved with concrete structures (buildings and bridges) as well as steel bridges.

Expert has experience designing concrete and steel buildings including high-rise buildings. He can do analysis and design of any concrete structure.

Expert is familiar with the design of concrete resistant to weathering conditions. Expert has diagnosed concrete deteriorations such as sulfate attack, alkali aggregate reaction, freeze-thaw deterioration, etc. He has also used corrosion inhibitors in concrete.

Expert can conduct structural evaluations of existing concrete structures. He has a lot of experience finding the reason for structural failure of concrete structures. He has performed failure analysis for a number of failed structures to find the main reason for the failure. Expert can determine the proper retrofit design.

Expert is very familiar with High Strength and High Performance Concrete (HSC/HPC). He can determine the proper mix design for high strength concrete.

Expert is an expert in most of the structural engineering fields ( structural analysis, finite element analysis, design of concrete structures, design of steel structures, wood design, and masonry design).

Expert has experience with state of the art structural repair systems.

He can provide evaluation and redesign of the existing structures, application of ACI code for structural evaluation and loading tests for his clients.

Expert is an expert in concrete materials and structures. He has designed numerous concrete structures. He has designed large span concrete thin shells for a public auditorium. He is very familiar with concrete durability. On several occasions, Expert has evaluated the structural integrity of the concrete structures to determine structural deficiencies or material deterioration.

He has evaluated several construction defects in buildings such as concrete failure, steel failure, and wood element (beams, columns, trusses) failure.

He is familiar with concrete mixes using numerous additives (admixtures) such as: water reducing, plasticizers, super plasticizers, micro silica, fly ash, slag, accelerating, retarders, air entraining, polymers, etc...


He has been a consultant for design of several special structures as follows:
Design of Concrete Silos and Bunkers for cement Industry;
Design of large span concrete domes;
Design of Concrete Reservoirs for Water and Waste water industry;
Design of High Rise Buildings;
Design of numerous bridge structures

He is a consultant for design of numerous residential buildings. The consulting includes structural design of industrial, residential and non-residential buildings. He been a consultant for Structural evaluation of numerous buildings. Structural evaluations are for structural deficiencies such as excessive deflection, concrete cracking, steel corrosion, wood deterioration, soil settlement etc. He has been structural witness for several structural failures.

Expert may consult nationally and internationally, and is also local to the following cities: Phoenix, Arizona - Tucson, Arizona - Mesa, Arizona - Glendale, Arizona - Scottsdale, Arizona - Chandler, Arizona - Tempe, Arizona - Gilbert, Arizona - Peoria, Arizona
