El Portal Design-Build Sidewalk Ext. Project

EL PORTAL DESIGN-BUILD SIDEWALK EXTENSION PROJECT

DESCRIPTION/SPECIFICATIONS/STATEMENT OF WORK

This project is a Design-Build (DB) which consists of constructing approximately 880 linear feet x 5-feet wide of new ADA concrete sidewalk to enable and provide safer pedestrian access to El

Portal de El Yunque’s Visitor Center. The proposed sidewalk is located within the Administrative

Site footprint of El Portal that was analyzed for the El Portal Revitalization Project in 2019/2020.

The proposed sidewalk to be constructed will run parallel and adjacent to an existing asphalt surfaced road and shall connect to an existing 5-feet wide sidewalk, located at the fee booth. The proposed sidewalk shall then continue to the egress off El Portal (see Appendix 2).

Installation of the proposed ADA sidewalk shall include all erosion control measures and BMPs, temporary traffic control measures, removal of topsoil, removal and re-planting of shrubs, removal and resetting of boulders, removal of two (2) existing trees, removal and resetting signs, sidewalk drainages, sidewalk construction around existing trees near El Portal’s entrance, new curb and gutter in specified area, ADA curb ramp(s) with detectable warning surface, installation and paintings of two (2) street crossings, and turf establishment.

During the duration of construction, the Contractor shall preserve and protect all existing structures, existing asphalt surfaced road, and protect vegetation (such as trees, shrubs, and grass) adjacent to the work site not found within the clearing limits, which are not to be removed and which do not unreasonably interfere with the work required under this solicitation.

Operations shall be scheduled and conducted to minimize erosion of soils and to prevent silting and muddying of streams, rivers, irrigation systems, and impoundments (lakes, reservoirs, etc.).

The DB contractor shall consider using rubber tire equipment to prevent damage to existing asphalt surfaced road. At no cost to the Government, the contractor shall be responsible and repair any damage to the existing asphalt surfaced road that deemed at fault by DB contractor.

The DB Contractor will be responsible for furnishing a 35%, 85% and 100% professional engineered design deliverable planset drawings for the Contracting Officer’s (C.O.) approval with finalized construction cost as reflected in the Schedule of Items. The 100% design deliverable shall be stamped and/or sealed by a certified Professional Engineer licensed in Puerto

Rico. Government final acceptance of the 100% design deliverable shall be approved in writing only by the C.O. before commencing of any construction work or activities.

The proposed ADA sidewalk design shall be designed and constructed to Forest Service

Supplemental Specification (FSSS), Standard Specifications for Construction of Roads and

Bridges on Federal Highway Projects per FP-14 Specifications, and USFS Standard Drawings.

All specifications, concrete design strength etc shall be reflected into the DB contractor’s design package as a submittal for government approval. The proposed sidewalk shall match the existing sidewalk in color and finished surface. Proposed sidewalk expansion and contraction joints shall be reflected in finished design and construction.

Prior to beginning work, the Contractor is responsible for identifying all appropriate commercial sources of material and equipment.

At all times during the performance of this contract and until the work is completed and accepted, the Contractor shall directly supervise the work or assign and have on the work site a competent superintendent who is satisfactory to the Contracting Officer and has authority to act for the Contractor. The superintendent shall be designated in writing to the Contracting Officer prior to the commencement of work. This individual shall be able to read, speak, and understand

English.
