I have read with much interest, a letter written by an out-spoken and articulated Engineer, Mr. Charles P. Ceres, PE, in your letter page on the 3rd March, 2012 and captioned “Someone must be able to demonstrate that engineers are performing an engineering function in this country”.
I humbly crave a space in your letter page, in the event and in the light of commending and acknowledging the above mentioned engineer for his technical comments and advices pertinent to Hydrological and civil engineering.
I just cannot agree with him more, as he basically expanded on soil preparation, in the advent of road building and general construction that are on-going throughout Guyana.
Sand in particular, as he emphasized, cannot be replaced or substituted for top clay soil or any earthen embankment, such as land filling or compact foundation.
It is well known from reality that sand does not sink into the soil but it can be feasibly and possibly shifted, swayed and washed away from one direction to the other.
It is now questionable, why Guyanese engineers have recommended sand to be land-filling, foundational use, etc. especially in and around watery environs.
I am a retired Hydrological engineer here in the Netherlands, since December, 2010. Prior, I have worked and served in such a capacity for more than 20 years. With such an experience, I can proudly say that I am qualified to voice my opinions on such a matter, pertinent to Hydrological engineering.
I have previously warned that the present ongoing steel-plates revetment at Hope-Craig, is a time bomb, meaning that after the lifespan of such steel-plates, there would an open cliff-space, of more than 10 meters perpendicular.
More so, I have learnt that the steel-plates were not being tarred prior their slicing/separating the river bed from the coastal land. This is pure nonsense and ridiculous. Tarred or oxide coatings not, would not prevent the river salt air from rotting the steel plates.
This is a grave issue right now in Guyana and must seriously be executed immediately. We have to retreat and beat back the sea and rivers.
With such a hydrological engineering, (revetment and land reclamation) silt would be terminated, feasible flows of heavy current water would be in advantage, reclaimed water front land would be accessible and beneficially in use.
Presently, I am in consultation and in negotiation with Ballast-Nedam here in the Netherlands, for us to merge and to set up such a hydrological engineering company in Guyana. Rev. Surujlall Motilall (Hydrological engineer from the Netherlands)
