… project is technically sound, among largestever government funded projects – JagdeoGovernment yesterday unveiled a $3.6B alternative drainage canal for the Demerara area and described it as one of its biggest projects ever to be funded directly from its coffers.Five years after the worst spate of flooding the country has ever seen coupled with the very real threat of a catastrophic collapse of the East Demerara Water Conservancy (EDWC), the government has finally broken ground on what President Jagdeo called, “a long term solution” to the threat of flooding from the EDWC.According to President Bharrat Jagdeo,Nike Shox Clearance, for many years villages in the area suffered from flooding with no immediate possibility of easing the situation when the EDWC is swollen to dangerous levels – a situation that occurs with greater frequency as each rainy season passes.The proposed channel joins the conservancy at a point on its north-eastern embankment and then cuts across 10.3km of the coast to spill directly into the Atlantic Ocean. Excess water from the Conservancy will drain into the canal via a three-door sluice at that end, run along the excavated channel and be spilt into the Atlantic via an eight-door high-discharge sluice structure.The canal also cuts one major roadway where the engineers have proposed a span resembling the truss bridges that currently cross the Mahaica and Abary Rivers.Chief Executive Officer of the National Drainage and Irrigation Authority, Lionel Wordsworth, highlighted the project background for those gathered to mark the occasion –a group which included farmers and residents from the adjoining communities which were hardest hit in 2005 and stand to lose everything should a breach occur in any of the conservancy embankments.He noted that a number of relief options were considered in the aftermath of the 2005 floods; among these were channels at Belmont, Hope/Dochfour and Nabaclis. Eventually the Hope/Dochfour option was chosen and the next step became the proposed design of the structure.Wordsworth said that a contract was signed with the consulting firm CEMCO on March 19, 2009 to deliver feasible design options in 16 weeks. The value of that design contract was some $56.4M however the consultant was unable to deliver the service as agreed within the stipulated time frame – a lapse that the consultant explained himself.Lead Consultant of CEMCO, Raymond Latchmansingh, explained the delay in the completion of the required design and report.? He said that what was a four-month contract became a much tougher job when the terrain, varying soil types and logistics were factored in.The first challenge was undertaking the topographical survey,Cheap NFL Jerseys China, this meant taking the measurements of the land they were intending to use, however as Minister of Agriculture, Robert Persaud,China NFL Jerseys, later explained, a large part of the land was swamp where the men would sink almost to their waists.Coupled with torrential rains, this added up to a situation where the topographical survey extended long past the time it would have taken on dry solid land. The next step was a hydrological survey of the conservancy and the surrounding area – this entailed measuring the dimensions of the waterways, flow rates in the channels as well as charting and recording the rainfall in the area.Then, the team had to undertake the geotechnical survey where the type,Cheap Jerseys From China, strength and other characteristics of the soil were measured.? According to Latchmansingh this in itself created a whole host of problems for the team since the terrain was a serious problem for the geologists.To undertake the survey they needed to drill boreholes around the site to remove soil samples for analyses but the fact that the rig kept sinking in the soft soil quickly put a halt to that process, eventually a Surinamese firm was contracted to undertake the geotechnical survey using CPT or Cone Penetration Testing.Originally developed in a Dutch laboratory, the technique makes it possible to undertake geotechnical scans of soil as well as delineating strata (or layers) by doing as the name suggests and penetrating the soil with a cone. Eventually the testing was completed and a design submitted to the NDIA for review.Yesterday CEMCO was conducting a test dig on a sample plot to determine the methodology that would eventually be used by the NDIA as they begin excavating the canal. The excavation will be done with the 14 long reach excavators acquired in December 2009 by the NDIA which, according to Wordsworth will save some 60 per cent of the excavating costs.The Geotechnical survey also allowed the NDIA to call for the supply of geo-textiles. According to Latchmansingh, the quality of the
