| In 1992, a voluntary team of civil engineers and laypeople designed, funded and constructed a 90-foot-long suspension bridge for the people of Chauffard, Haiti. This is their story, as told by Kenneth E. Wilson, P.E. |

A BRIDGE THAT WILL SAVE LIVES Running through Chauffard (Haiti) is a dangerous river that schoolchildren must cross to get to their mission school and that farmers must cross to take their crops to market. Each year during the flooding season, two or three people, most often schoolchildren, are swept away to their death by the raging current. Upon learning of this condition, a voluntary joint venture, consisting of the Foundation for International Development Assistance (FIDA), Engineering Ministries International (EMI), the Michael Baker Corporation (an engineering firm based in Pittsburgh, PA), and a local Haitian church, the Harmony-Zelienople United Methodist Church, stepped in to design, fund, and construct a 90-foot-long steel suspension bridge for the people of Chaufford. |

PRIMITIVE CONSTRUCTION TECHNIQUES The Haiti Eight, as [the volunteers] came to be known, helped the Haitian people erect the 20-foot high steel towers, pour the 10-inch thick concrete tower pads, and excavate and set reinforcing steel for the 54,000-pound concrete anchor blocks. Brent Wolff, who has lived in Haiti with his family for the past five years, then lead and assisted the people of Chauffard in pouring the anchor blocks, assembling the suspension cable system, placing and welding the steel plate deck, and finally painting the entire bridge. |

Since the bridge site is so remote, all bridge materials were transported by foot down a steep and winding half-mile path from a truck to the bridge site. The Haitians and their American co-workers hauled 200-pound pipes and 90-pound bags of cement over the mountainous terrain, with the Haitian children generally leading the way and leaving their new American friends with wounded pride and sore muscles. |

With no conventional construction equipment available at this remote mountainous site, the bridge was constructed using only support cables, a welder, and a lot of ingenuity and fortitude. Steel pipes were assembled and welded into towers, braced with steel angles, and capped with a steel saddle to support the main cables. Working side by side, the Haiti Eight and the local Haitian people chiseled away at the rock in both the tower pads and the anchor block holes, slowly excavating them to their proper depths. Reinforcing steel was cut by hand and was bent about a large rock near the bridge site. |

About 30 Haitians joined the Haiti Eight in raising the 20-foot high towers into their vertical positions. A great roar went up from the assembled Haitian crowd when the towers were finally upright, and the Haiti Eight breathed a collective sigh of relief that none of the towers wound up in the 100-foot-deep canyon. Using a primitive yet innovative system of strings and plumb bobs, the team positioned, squared, and leveled the towers. |

THE HAITIAN PEOPLE While many professionals were involved in the design and construction of this bridge, the local Haitian people, who will use the bridge and who made the decision to build it, played a major role in constructing it. However, Wolff is occasionally discouraged by his work in Haiti, and he compares the Haitian people with a group of crabs stuck in a bowl. "When one crab is about to make its way out of the bowl," he says, "the others drag it back down, not allowing it to escape its desperate conditions. When a crab finally does make it out of the bowl, it never looks back or returns to show the others the way out." But he uses another word picture to illustrate his reason for staying in Haiti. "If an ocean storm strands thousands of starfish on the Haitian beach, it may seem pretty futile for someone to begin throwing them back into the ocean, one at a time. But it sure makes a difference for the ones he does throw back." |

A PEOPLE SERVING PROFESSION In addition to helping to construct the bridge and leaving a supply of food, medical supplies, and clothing, the Haiti Eight also left a small bronze plaque for the bridge with the words, "Pon Chofa, Depi ke Jezu to sevi tankou yon pon ant Bondye e nou menm lanmou Jesu fe nou konstwi pon sa-a pou ou e nou Dedye-l pou glwa granmet la." ("Chauffard Bridge, since Jesus bridges the gap between us and God, the love of Jesus compels us to build this bridge for you and dedicate it to God's glory.") Wilson says of his experiences in Haiti, "This project has been a dream come true for me, allowing me to apply my bridge engineering skills in a cross-cultural setting. There's something special about the Haitian people that draws you like a magnet. They have taught us all a lesson in contentment and fortitude, and we have received a lot from the Haitians as well as giving to them." |
