The 2,000-foot to WEST ELECTRIC COMPLETED THE FIRST-EVER HIGHWAY TUNNEL IN PUERTO RICO. BY RUSS GAGER he lighting is a showstopper,” says Fernando Sumaza, president of West Electric Corp., in Myaguez, Puerto Rico, about his company’s contribution to a double highway tunnel carved 2,000 feet into a mountain near Maunabo. Located on the southeastern end of the selfgoverning commonwealth and unincorporated U.S. territory, the tunnel has the latest lighting features, Sumaza emphasizes. Lighting levels are modulated throughout the length of the two, two-lane tunnels so they brighten when entering the tunnel to adjust to leaving the brightness of sunlight. But as drivers continue at approximately 40 to 45 miles per hour through the tunnel and their eyes adjust to the darker conditions, lighting levels are lowered. “When exiting the tunnel, there’s way less light, because your eyes have adjusted to the lighting level inside,” Sumaza explains. Lighting at night can be much dimmer than during the day. “We have light sensors in the tunnel that check for light levels inside,” Sumaza continues. “When it hits a threshold, it changes into night mode. “We also have a system of lights when the power goes out,” he relates. “It usually takes 20 seconds for the generator to kick in. We have lighting fixtures, but putting a battery pack on each fixture would cost way too much.” So instead, two uninterruptible power supplies (UPS) were installed, one for the lights and one for the system. “It works faster than a generator,” Sumaza points out. “Not all the lighting is on UPS, but a certain amount is constantly. If you kill the power to the system, the UPS has batteries inside it and power comes on. The batteries keep lighting going continuously while the generator starts up, and then it gets substituted for the UPS.” If the power outage continues, information boards at the entrance to each tunnel automatically generate messages instructing motorists CONSTRUCTION-TODAY.COM DECEMBER 2009 http://www.CONSTRUCTION-TODAY.COM
