J-Dos Management Services for this citywide alleyway restoration project enabled DDOT to complete the restoration of 8 alleyways in each of the 8 city wards for the FY15 Alley Palooza 1 & 2, in all 128 alleyways were restored. Notably, the 64 alleys in the Ally Palooza 1 program was completed 2 weeks ahead of the 8-week schedule. The schedule required that the roadway and alleyway restoration activities run simultaneously, requiring a staff of 14 inspectors at the height of activities.

J-Dos was also proactive in creating, building upon and improving DDOT alleyway pavement repair management database, using real time uploading and data entry of field inspections reports. This shorten the time required for field inspections and analysis for pavement maintenance planning.

J-Dos was also in charge of Public Outreach Services this involved: drafting and distributing notification letters to residents, local businesses, and ANC Commissioners outlining project impact and length. Visiting project locations before the onset of construction, providing face-to-face outreach services to stakeholders. Attending public meetings, provided administrative support for project team, and worked closely with DDOT Outreach Coordinators to ensure success.

Project Summary

In January, 2015, the Ministry of Public Works, Works Services Group (WSG), in conjunction with the Guyana Geology and Mines Commission GGMC), engaged the consulting Team, J-Dos Internationalé, Inc. to provide engineering designs and supervision of works for the Parika to Goshen Road. One of the key challenges to the mining industry is the ability for miners to access the various mining locations; in addition, the opening of this new road would facilitate access to many agricultural lands in the region.

The proposed Parika to Goshen Road is approximately 56 km (35 miles) long and runs within the right-of-way of the 1962-66 old road alignment (known as the Del Conte Road) on the east bank of the Essequibo River, passing through occupied agricultural and forest lands. It crosses over eighty (80) streams of varying widths from 12 m (40 feet) to 119 m (393 feet). Three (3) major crossings – Naamryck, Bonasika, and Makouria will require extensive civil works before being bridged.

J-Dos Role

J-Dos as the prime consultant is providing Program Management Services which include engineering designs and supervision of works for the construction of the new road and associated structures.
