Sustainable Construction represents the commitment to
the resources and quality of life of future generations. Reductions in the carbon footprint through the use of supplementary cementitious materials, development of energy efficiency aerated concretes, design of longer lasting
structures, utilization of locally available materials, and
use of waste by-products are among the many techniques
that have been incorporated into construction projects.
As the emphasis on long-term performance and construction costs controls increases, greater importance is given
to assessing the service life of new or existing construction and/or repaired structures. Service Life Analysis expertise and experience has proven of great importance in
developing models of service life predictions in structures.
These predictions have provided supporting information for
evaluating specification requirements, materials selection,
protection measures, and maintenance programs.

Panama has seen construction at a scale not seen by many as a result of the new revolutionary canal expansion project. The expansion
consists of a new lane of traffic along the Canal which is made possible by the installation of a new set of locks. The expansion will allow
double the waterway capacity as the original Canal, and Post-Panamax vessels will have the ability to transit through the Canal with up
to 13,000 Twenty-Foot Equivalent Shipping Container Units (TEUs), tripling the original Canal’s size limit. The project intends to meet
current and future demand growth while obtaining a cost advantage through economies of scale which will allow the Canal to keep a
competitive advantage through higher perceived value of the maritime route that Panama has to offer. The total expansion costs are
estimated to be around $5.25 billion dollars. CA was retained in July 2012 to serve as an independent consulting expert to the owner/
administrator of the Panama Canal, the Autoridad del Canal de Panama (ACP), in matters regarding aggregate and concrete used in the
canal expansion project.
Located atop a hillside on the northern shores in the city of Arecibo, Puerto Rico, a Christopher Columbus Statue is being erected and
is projected to be completed by late summer of 2015. This project consists of the erection of a statue twice the height of the Statue of
Liberty without its pedestal, and so tall that it could interfere with air traffic once erected. The Statue consists of over 2,000 exterior pieces of copper and bronze connected to an interior structural steel frame for a total weight of over 600 tons. The structure was
originally designed by Russian sculptor Zurab Tsereteli in 1991 to commemorate the 500th anniversary of Columbus’ 1942 arrival to the
Western Hemisphere. CESG’s contribution to the project included consulting services in regards to the mat concrete foundation consisting
of the structural design, project specifications development, material condition assessments, and construction management. In addition,
CESG’s project involvement also included the development of the concrete mixture proportions, concrete placement sequencing, quality
control, temperature and maturity monitoring, and implementation of early age protection measures of the mass concrete elements.
Over 1,500 cubic yards of concrete were placed in approximately 8 hours, during which all concrete loads were accepted, there was no
evidence of cracking within the mat foundation mass concrete elements, and all the concrete compression strength tests exceeded the
28-day specified design strength in 7 days.
In May of 1997, the world renowned architect, Tadao Ando, was selected as the architect for the Modern Art Museum’s building in Fort
Worth, Texas. The museum is a 150,000 square foot building sitting on an 11-acre property. CA provided consulting services for the
production and construction of the architectural concrete including, among others, material selection, concrete proportions, batching,
quality control, formwork, concrete placement, and consolidation. Notable features of the building included: a natural setting utilizing
existing major trees on site augmented by additional trees, shrubs, and plant materials native to North-Central Texas; three gallery
pavilions that appear to float above a shallow reflecting pond to the north and west; double skin or envelope inner structural walls of
cast concrete to protect interior gallery spaces and support large projecting roof planes above; outer glass and metal panel walls to
provide public circulation areas from which to view the museum’s landscaped exterior and reflecting pond; and immense concrete roof
overhangs, supported by Y-shaped columns on the east side to help shade interior spaces surrounded by 36 foot glass walls constructed
with energy-efficient insulated glass units.
