Description

The project work includes channel excavation using backhoes, trucks, shovels and bulldozers; levee construction; installation of culverts; construction of highway ramps and utility relocations. Levee construction will require hauling borrow fill from borrow areas located away from the project, therefore, extensive use of highway trucks is anticipated. This is a flood control project to protect towns near the Manati River. Project work includes construction of 5,300 meters of levees around the town of Barceloneta and 1,545 meters of pilot channels in the Rio Grande de Manati. The east levee extends for about 3,200 meters and would require approximately 508,000 cubic meters of fill material. Due to the east levee construction, a boat ramp, which is approximately 12 meters long with a parking lot and a paved access road will be constructed near P.R. Highway 684. The west levee extends for 2,100 meters and would require approximately 200,300 cubic meters of fill material. The total length of the levee would have an average height above ground of 5.4 meters, 1 on 3 side slopes on the east levee, 1 on 3.5 side slopes on a portion of the west levee, a levee top width of 3.0 meters, and an average levee base of 38 meters. Two portions of the existing Rio Grande de Manati channel cutoff by the east levee would be replaced by pilot (bypass) channels. The upstream channel would have a trapezoidal cross section with 1 on 3 side slopes and a 15 meters bottom width at elevation -1.1 meters NGVD. The side slope of upstream channel near the levee and the levee near the pilot channel would be revetted gabion matresses. The downstream channel is located about 750 meters east of the existing channel. The downstream channel would have a trapezoidal cross section with 1 on 3 side slopes and a 15 meters bottom width at elevation 2.2 meters NGVD. The project plan requires the construction of minimum interior drainage facilities to collect and dispose of urban runoff caused by a local rainfall event. The drainage facilities will consist of 5,230 meters of drainage ditches along the protected side of the levee, drainage culverts under two highway ramps, and two drainage structures on the levees. The drainage ditches would be constructed with a triangular cross section with an average depth of flow of 1.5 meters and an average top width of 9.0 meters. Corrugated metal pipe culverts for interior drainage would be provided under P.R. Highway 681 ramp and the agricultural road access ramp. The drainage structures on the levees, Culverts 1 and 2, consist of corrugated metal pipe culverts with flap gates and concrete headwalls. Due to levee construction, 3 highway ramps will be required at P.R. Highways 681, 682, and 684. The P.R. 681 ramp will have a length of 447 meters and require approximately 23,600 cubic meters of fill to construct. The P.R. 682 ramp will be 428 meters long and require 16,300 cubic meters of fill. P.R. 684 ramp will be 314 meters long and require 25,000 cubic meters of material for construction. All road relocations will be paved with hot bituminous mix surface course and have crushed gravel or crushed stone as the base material. These road relocations require traffic control along with maintenance/detour plans. The project also requires utility coordination due to power and telephone line relocations along the proposed highway and levee locations. Two manholes will be relocated/raised and will require new tops. The job requires knowledge of construction methods and practices that minimize or negate environmental impacts including turbidity, noise, and dust. Turbidity monitoring will be required and cessation of all earthwork activities will be required should turbidity levels exceed 29 NTU over background levels. The borrow area is within the endangered Puerto Rican Boa's habitat and the contractor will be required to engage the services of personnel knowledgeable in it's biology monitor for it's presence. Cessation of work within the borrow area and capture and relocation is required if a boa is found. It is anticipated a commercial borrow source will be required to supplement a shortfall of material from the project borrow area. The project will require the contractor have sufficient personnel and equipment resources to engage in multiple construction activities at different locations in and around the municipality of Barceloneta and coordinate his activities with local, municipal, and commonwealth agencies. Magnitude of construction is over $10 Million. Invitation for Bids DACW17-01-B-0015 will be issued on or about 9 July 2001 and bids will be received on or about 23 August 2001.
