Geotechnical Instruments

Every geotechnical design is to some extent hypothetical, and every construction job involving earth or rock runs the risk of encountering surprises. These circumstances are the inevitable result of working with materials created by nature, often before the advent of human beings, by processes seldom resulting in uniform conditions. The inability of exploratory procedures to detect in advance all the possibly significant properties and conditions of natural materials requires the designer to make assumptions that may be at variance with reality and the constructor to choose equipment and construction procedures without full knowledge of what might be encountered.Field observetions, including quantitative measurements obtained by field instrumentation, provide the means by which the geotechnical engineer, in spite of these inherent limitationsm can design a project to be safe and efficient, and the constructor can execute the work with safety and economy. Thus, field instrumentation is vital to the practice of most geotechnics, in costrast to the practice of most other branches of engineering in which have greater control over the materials with which they deal.

Wind Monitoring

Wind resource data are often available from public and private sources, but is inadequate to meet the information needs of ISOs, wind farm operators and developers, power traders, resource analysts and government. These data sources are designed for aviation and consumer weather markets. They do not meet the need for actual wind speed data at the hub height and above the boundary layer of 80 meters. Usually, surface data from 30 or 40meter towers within the project boudaries is used to "guesstimate" UP to the hub height of today"s utility scale wind turbines. Or satellite data is used to project DOWN to land based wind farm projects. Both are inaccurate and inadequate to meet investor due diligence and to support wind power integration into the grid. All parties are focused on satisfying investor need for de-risked projects recognizing capital as the top barrier to wind power deployment.

Wind Sensors

GaiaComm provides all type of sensors available in the market in order to measure wind speed and direction, temperature, barometric pressure, hummidity etc.. Additonally we equip our systems with data loggers that offer flexible programming solutions with powerful data storage and a wide choice of communication options, all key elements of any wind prospecting or wind profiling system.

Post-Tensioning Systems

Post-tensioning is a means of strengthening or reinforcing concrete by introducing stress to the element using high strength steel bars or strands. A compressive force is applied to the concrete member, which strengthens the slab and can allow it to remain in compression when it flexes under applied loads. This method of construction provides many benefits over traditionally reinforced concrete. In buildings it can provide thinner slabs resulting in lower building heights and consequently a reduction in the amount of concrete required, thereby offering both cost and environmental benefits. Longer spans can be achieved which increase layout flexibility and offer cost-savings in terms of service location and maximisation of valuable floor space. In the design of bridges, post-tensioning can allow the creation of longer, more slender spans with fewer supports thereby facilitating the design of more elegant and aesthetic structures. Post-tensioned concrete can also minimise problems of cracking and settlement, to improve structural durability and longevity.
