The following construction-related designs were produced for specific Real Estate developments. Even if they were all sufficiently different as to merit their own patents, the circumstances made patent applications a secondary concern and they were never submitted.

For the "Rio Lama" development: Design and development of a hybrid prefabricated system and special steel forms for the construction of the 650 apartment Rio Lama complex in Barquisimeto, Venezuela. A masterpiece of industrialized concrete residential construction, this system was entirely developed by myself and permitted such a degree of industrialization that a building needed only 3 months to be completed from scratch. All partitions were prefabricated as well as the circulation module. (see "Projects" for more info and a map)
 
For "La Cima" development: Design and development of a second kind of hybrid prefabricated system and special metallic forms for the construction of the 212 apartment La Cima complex in Caracas, Venezuela. This design, also 100% developed by myself, permitted a high degree of industrialization, but this time in a high-rise (12 floor) environment. Noteworthy was the facade system and its method of installation. (see "Projects" for more info and a map)

For "La Virginia" development: Design and development of a third kind of hybrid prefabricated system and special forms for the construction of a 134 unit single floor town house complex in La Virginia, Sta. Lucia, Venezuela. This system used cast in place walls and prefabricated roof slabs. Again, like in Rio Lama and La Cima, a high degree of industrialization was achieved and a row of houses was finished in weeks. The whole concept was designed and developed by myself. (see "Projects" for more info and a map)

For "La Esmeralda" development: Design and development of a system to pour retaining walls formed on one side only. With this system some 2 miles of retaining walls were built in La Esmeralda, Valencia. The concept was designed and developed by myself. (see "Projects" for more info and a map)

For two homes in Caracas: Design and development of large, variable-speed, motor-operated, pivoting, three-dimensional steel and glass structures for two homes in Caracas, Venezuela. (See pictures above, left)

For the "Casa Guri" project: Conceptualization and implementation of a method to guarantee complete financial fairness to investors in joint ventures supplying different amounts of money at different times, based in obtaining equal internal rates of return for all investors (probably non-original, but a pearl of financial mathematics, nevertheless).  To view this financial model, open the following link: resources/Example of IRR.xls (see "Projects" for more info and a map)

For the "Casa Guri" project: Development of a method for building a geometrically perfect, rectangular-based brick dome, in Los Cabos, Mexico. The method represents an important advance in the art of rectangular-based dome-making, until then subject to unsightly imperfections in shape (See pictures below and above, to the far right). Unfortunately, the low-quality picture does not convey the exquisite beauty of the "soufflé" shaped dome. The approximate dimensions of the base are 15 feet x 12 feet and the height at center is about 4 feet.

Other designs not related to construction

Ergonomic design of a chair: Obsessed with the general discomfort of chairs, I designed a super-comfortable chair that I could build myself in my own workshop. (See photo below). I built 10 units like this, including two scaled-down (70% and 80% scales) versions for children.


Ergonomic design of a laptop computer stand: by petition, I designed and built a laptop computer support that allows to work while sitting or while laying down on a couch. (See photo below).

Design of a cabinet using the Golden Ratio proportions: I designed and built this cabinet, using the Golden Ratio proportions, to house my collection of antique instruments and machines.
