NAREI inks $13.8M contract for geotextile tubes in Essequibo

Sep 15, 2017 News

With the aim of strengthening sea defence in Reliance, Essequibo Coast, Region Two, the National Agricultural Research and Extension Institute (NAREI) on Wednesday signed a $13.8M contract with Samaroo Investment for the installation of geotextiles tubes.
NAREI’s Chief Executive Officer (CEO), Oudho Homenauth, and Doodnauth Samaroo, Managing Director of the contracting company, signed the contract at NAREI, Mon Repos, East Coast Demerara (ECD) location.
The contract specifies that 100m geotextiles tubes are to be installed to form groynes along the foreshore at Reliance, Essequibo. The general scope of works includes the alignment of 100m geotextile tubes with a circumference of 30 feet and geotextile layers (scour aprons with four feet circumference anchor tubes and Geo-grids) perpendicular to the existing sea defences and sand fill tubes using slurry. Groyne shall be placed 10m from the sea defences.
Geotextile tubes are used as a cost-effective material alternative for coastal and marine projects. They are manufactured from geosynthetic based materials which are factory sewn to achieve the desired formation. Installation of the tubes is carried out by filling with sand or suitable dredged material.

NAREI’s CEO hands over the contract to Mr. Samaroo as Kene Moseley, Project Coordinator (left) and Luanda Jack, Project Engineer of Mangrove Restoration and Management Department look on.

To strengthen coastal sea defence, NAREI has over the years implemented a number of interventions throughout the country. In Essequibo, interventions were made for the restoration of mangroves and creation of suitable environment to promote restoration in areas where the supporting criteria does not exist.
The entity has completed seedling planting at Lima, Essequibo, resulting in successful restoration and natural regeneration extending the forest length and width. Geotextile tube groyne and spartina planting at Devonshire castle were done and this resulted in increased elevation and natural regeneration.
Currently, bamboo brushwood dam that was done in Walton Hall is being monitored and is expected to support increased elevation. NAREI will follow up with Spartina grass planting.
