First Bank- Galeria San Patricio Branch: (2004)

Project consisting of a 4,000 s.f. interior space at an existing commercial building.  A innovative atmosphere was created by the architect by using a “wave” style suspended ceiling, to complement this, general illumination was achieved with vertically mounted fluorescent fixtures that pierced through the suspended ceiling plane.  Our design also included interior electrical facilities for power distribution, security, telecommunications and an on-site stand-by generator.

Sun Bay Marina: (2000)

Located in the eastern part of P.R.,consisted of 141 slips dedicated for boats from small cruisers to large luxury yachts.  Our design included the electrical and CTV distribution for the project, which included the electrical distribution for the slips power centers, substations, administration and commercial facilities.
An interesting and challenging feature of this marina is that it was completely built on piles over the water including parking, administrative and service facilities.
This is one of the many marinas we have design throughout Puerto Rico and the Virgin Islands.

Finished Goods Warehouse - McNeil C&SP, Las Piedras, P.R.:  (2006)

A 20,000 finish goods warehouse for the McNeil C&SP pharmaceutical plant in Las Piedras.  The project scope included a secondary unit substation with power factor correction capacitors, complete 480/277 & 120/208V voltage power distribution system, energy efficient fluorescent high bay lighting with a fully automatic occupancy sensor system throughout the entire warehouse and signalling systems (CCTV, FA & Telecomm). JRR performed 100% of the power, lighting and signalling design for this project.

Institutional Projects

A high school vocational complex with more than 20 classroom buildings distributed in a 20 acre (875,000 sq. ft.) land lot with covered basketball court, cafeteria building, amphitheater, administration building, vocational workshops, etc.  The project required a dedicated 38kV utility connection, 38kv private substation and various loop feed 13.2kV pad mounted transformers.

Bayamon Pediatric Hospital - Hermanos Meléndez: (2004)

New 131 bed healthcare facility part of the well-known Hermanos Melendez Hospital Campus.  Facility is dedicated to pediatric care and includes pediatric emergency room, radiology, pediatric and neonatal intensive care units and surgery ward.   Electrical distribution system consists of two 1000 KVA pad mounted transformers connected at a primary voltage of 13.2KV.  Secondary distribution was done at 277/480V.  The electrical design was done in strict accordance with the governing codes for healthcare facilities, including the use of three different power distribution  systems for critical, essential and non-essential loads with a redundant 100% stand-by generating system which will shed power in order of priority in the case of system failure.  Interior lighting design was instrumental in creating an atmosphere of wellness for the pediatric patients.
A unique characteristic of this project is that it was designed in a partially completed office building.  This connection represented a great challenge and required an intense coordination with the mechanical systems and the architectural features due to the limited spaces available.
