He is leading the company to great heights with more than 20 years of experience in the field of structural design. He is experienced in the design of a wide variety of building types including retail centers, office buildings, schools, hospitals, university campuses, residential housing, high rise buildings and renovation and retrofitting of structures. He has thorough understanding of construction economy and its application. His expertise lies in developing innovative, sound structural systems which appeal to the architectural aesthetics

We have earned a reputation for designing large structural engineering projects. The Company has given consultancy service for commercial & multistoried Residential Building, Hospitals, Malls, Religious buildings, Educational institutions, auditoriums, Hotels, Stadiums, Water tanks, Industrial Structures and Public Infrastructures. As a Design Consultancy firm, we have rendered our services to some of the foremost urban spaces and systems in Kerala and all over India. The breadth and amount of our work earmark our goal to give the best. We ensure diversity in our projects that our clients entrust upon us.

Mr. Rojan Mathew is a post graduate from Indian Institute of Technology, Gandhinagar, Gujrat(IIT Gandhinagar) and Graduate from National Institute of Technology, Calicut, Kerala(REC/NIT Calicut). He is an expertise in the field of seismic design and dynamic analysis. Aftercompletion of studies, he was working in Ahmedabad. He is is well versed with variousstructural design and analysis softwares like STAAD PRO, SAP2000, ETABS, SAFE,MATLAB, AUTOCAD etc. He has experience in the seismic design of water tanks, multistoryresidential and commercial buildings, shopping malls, educational institutions, hospitalsretaining structures like diaphragm wall.

Practicing at the confluence of Architecture, Sustainability & Quality by offering disruptive building technologies, we collaborate with clients & technocrats to create Buildings in harmony with the Environment

We have established a State of the Art manufacturing facility in collaboration with our European associates, bringing in Innovation Industrialization & introducing a paradigm shift in the concept of construction of buildings.

The consortium is instrumental in Design, Engineering & providing turnkey solutions, training of local partners,enforcing stringent quality controls to ensure that projects are delivered and executed as per international standards.

Although simple the system is unconventional and requires a slightly different approach from standard structural design & construction; Standard design software like STAAD, ETABS, SAP etc. are used for design analysis; Optimization and effective design is paramount and a special Schnell Cad software is used to generate all the structural panels to detail in manufacturing all the elements.

Panels are precisely produced and also often adjustable to site conditions; the panels & modules are assembled with set of instructions. Depending on the size of the project, typically a 3000 sq.ft building requires a team of 6 to 10 trained craftsmen and a dedicated supervisor to carry out the installation in a timely and efficient manner. Estimated about 60 days for complete Shell and Core installation.

During the period, I familiarized with British standards such as BS 8110, BS 8007, BS 6399, CP3 Chapter V-2, etc., and manuals such as IStructE manuals for standard detailing. Further, I got familiarized with structural analysis and design softwares such as MIDAS Gen, ETABS, SAFE, and PROKON. I started the regular CPD by participating in the FEM software workshops, IESL seminars, short courses and Conferences, Question times arranged by SSESL etc. Since Design Advocacy (Pvt) Ltd provides consortium consultancy service, I always had the opportunity to work in-house with different professionals in the construction industry, such as Architects, Service engineers (M&E), QS, and Urban Designers etc and obtained a good understanding of their role & responsibilities in a project.

After familiarizing with the basic design concepts, I experienced in design by getting involved with different types of projects from small houses to large scale buildings. Usually, I had to work on two to three independent designs at a time. It is sort of an absolute requirement of our office to visit the near sites before commencement of design work, to obtain first-hand information about site terrain, access to site, available services, surrounding buildings, ground conditions and ground water table etc. I visited assigned sites, inspected the construction works such as inspections of each slab & beam reinforcements, piling works etc. and participated the progress meetings. Following were some major projects I got involved during this period.

On October 29, 2008, over one hundred people came to the Helen Mills Theatre in Midtown Manhattan to listen to Professor Xueyi Fu, director and chief engineer of China Construction Design International, discuss the building concept, behavior and geometry of the polyhedron frame structure, structural analysis and research, geotechnical conditions, and the unique construction of the National Aquatics Center. The Water Cube was selected as the winning entry of an international design competition and was submitted by a consortium consisting of China State Construction Engineering Co. (Beijing), China State Construction International Design Consultant Co. Ltd. (Shenzhen), PTW Architects (Sydney), and Ove Arup PTY. Ltd. (Sydney).

Back in 1887, physicist Lord Kelvin questioned how a three dimensional space could be divided into cells of equal volume with minimal surface area, such as a natural formation of soap bubbles. Kelvin proposed a "foam" consisting of tetrakaidecahedra, a 14-sided polyhedron with six square sides and eight hexagonal sides. It wasn't until 1993 that Weaire and Phelan discovered a more efficient array consisting of two 12-sided polyhedrons and six 14-sided polyhedrons. The steel space frame structure of the Water Cube is essentially the Weaire-Phelan answer to Kelvin's question with a slight twist. To create a more natural look, the template for the space frame was cut out from a rotated array of polyhedrons.

The steel members were encased by a "film" of some 4,000 ETFE (ethylene-tetrafluoroethylene) cushions filled with low-pressure air. ETFE is a special polymer that is one percent the weight of glass and can also transmit more light through its surface. A total of 100,000 square meters (1.1 million square feet) of ETFE were used in the Water Cube. The ETFE cushions improve energy efficiency by allowing solar energy to heat the pools, protect the steel members from the high levels of condensation in the swimming pool environment, and are illuminated by LEDs for impressive displays of changing colors at night.

A variety of software programs were used to evaluate the substructure, superstructure, and overall structure of the Water Cube including ETABS, MIDAS, MST, SAFE, SAP2000, SATWE, STRAND7, and TAT. The steel structure was optimized to make it as strong but as light as possible, accommodating dead loads, roof loads, wind loads, earthquake loads, and temperature effects. Bending moments were reduced in high stress areas and different stress levels were developed for the walls and roof to achieve a strong-column, weak-beam design to achieve good seismic design.

The design of the pile foundation for the Water Cube needed to account for differential settlement rates between the pools and main structure. Two design load cases where analyzed: one with the pools filled with water and another with no water in the pools. As there would be an uplift effect when pools are emptied for cleaning, compression piles were used below the main structure, tension piles were used below the pools, and compression and tension piles were used below the boundary areas.

The Water Cube accommodates a competition pool, diving pool, and warm-up pool in the 177 m x 177 m x 31 m (580 ft x 580 ft x 102 ft) structure. The venue held 17,000 spectators during the Olympics and its capacity will be reduced to 6,000 when the temporary seats are removed and interior parts of the building are converted a fitness and recreation center that is open to the public. No changes will be made to the main structure after the Olympics.
