The Central Ohio STEM Expo is a free central Ohio community outreach event for students grades K through 8 to explore the world of Science, Technology, Engineering and Math. At the inaugural event in 2014, the American Society of Civil Engineers Central Ohio Section welcomed over 140 students to participate in interactive activities and exhibits in the STEM fields. The ASCE Central Ohio Section is pleased to announce the 2nd Annual Central Ohio STEM Expo will be held on Saturday, February 28, 2015 at the Metro School from 9 AM to 1 PM.

Purpose and Background
Time of concentration is a frequently overlooked parameter in urban drainage design. It is often calculated using one of several common equations that are selected based on user familiarity rather than on the characteristics of the drainage basin. Time of concentration can also be calculated incorrectly when the emphasis is placed on finding the longest flow path, which often is not appropriate when used to determine peak flows. This webinar will cover the Kirby-Hathaway Equation; the Kirpich Equation; the FAA Equation; the SCS Method for computing time of concentration; as well as a solution using the physical concepts of sheet flow, shallow concentrated flow, and open channel flow. The webinar will include examples of the different equations and a discussion on when the use of each equation is appropriate. It will also include a discussion on requirements for time of concentration calculations in stormwater design manuals.

Join us in celebrating the engineers that make the world a better place.

Topic: Engineering New Horizons: Honda and The Power of dreams

Speaker: Clement D’Souza, Engineering Large Project Leader, Honda of America Mfg., Inc.

Clement D’Souza is an engineering large project leader at Honda of America Mfg. currently assigned to the New Model Group for the Acura NSX and the startup of the new Performance Manufacturing Center.

Clement will talk about his experiences working with Honda, in particular,

• Good engineering starts with the willingness, ability, and empowerment to dream. At Honda we believe that dreaming big is the key to success.
• Clement will share what he has learned since he started at Honda, how the challenges he faced in launching mass production products prepared him for the biggest challenge of his professional career - developing a state-of-the-art manufacturing facility that will build the first-ever produced super sportscar in the United States.
• As the production leader for the NSX project, Clement will explain the thrill in creating an all-new plant to build an all-new super sports car. He will talk about the focus of him and his team on creating a plant that has the perfect synergy between man and machine.

Purpose and Background
During the past 50 years, roadway infrastructure in the urban environment has been focused on moving vehicles as quickly as possible from one place to another – generally into the city in the morning and to the suburbs in the evening. As urban living becomes more popular and dependence on the automobile becomes less desirable, city officials are looking at ways to transform roadway corridors into comprehensive transportation networks. This hierarchical network needs to function efficiently to support the movement of people and goods, as well as benefit the communities in which they are located. This webinar will show various challenges and solutions addressed in a rehabilitation infrastructure project in Washington DC – the Rehabilitation of H Street NE.

Purpose and Background
Concrete has been called durable but not eternal material. Despite its longevity, it eventually deteriorates and requires repair or replacement. This webinar focuses on repairing deteriorated concrete and restoring its structural capacity. (A related topic on strengthening concrete buildings in sound condition is addressed in a separate presentation.) The webinar provides a succinct overview of the issues involved in repair of concrete structures, with a focus on practical solutions useful for a design engineer.

Purpose and Background
Design of foundations for equipment support is often required in industrial and process facilities, yet this topic is rarely, if ever, included in the engineering college curricula. Engineers are left to learn on the job – a process that often produces a variability of foundation designs for similar installations. In some cases the design is performed by the engineers who may or may not even have structural background. Yet whenever any component of an equipment foundation fails, the resulting strengthening and retrofit activities are often very expensive and intrusive into the equipment operations.

Topic: EWB Update - Flood mitigation project in the Esfuerzo de Paraiso, Dominican Republic

(Online registration and payment available, see bottom of page.)

This presentation will be on the Central Ohio Professional chapter of Engineers Without Borders USA. The guiding principles of EWB are based upon sustainability and community ownership and involvement. The implementation of these philosophies will be reviewed through a case study of two projects undertaken by the Central Ohio chapter of EWB. The first project is a municipal roadway project in the Las Pilitas neighborhood of San Pedro Puxtla, El Salvador. The project constructed a 400 foot long street and drainage system for an isolated residential area at the edge of the village of San Pedro Puxtla. The street, which is now complete, connects the Las Pilitas neighborhood to the rest of the town, eliminates unhealthful exposure to contaminated drainage, and allows safer access to the residences in the rainy season. The project was named the 2014 project of the year by EWB-USA. The second project is a flood mitigation project in the Esfuerzo de Paraiso neighborhood of Santo Domingo Norte, Dominican Republic. The Esfuerzo de Paraiso neighborhood, located within a floodplain, bounded by the Yaguaza river to the west and an agricultural canal to the east, experiences frequent and severe flooding. The residents experience near weekly flooding during the rainy season (April through October) with flood water reaching as high as 10+ feet during hurricane level events. The floodwaters also carry contaminants from nearby trash dumping piles and restrict access from the neighborhood to the surrounding city. The Central Ohio Professionals chapter is currently teamed with the OSU student chapter in the assessment phase of this project.

Purpose and Background
Many renovation projects involve strengthening of foundations. Whenever an increase in gravity loading or a lateral load retrofit is proposed, foundation strengthening is likely to follow. Underpinning, the lowering or enlarging an existing foundation, is a basic technique of foundation strengthening. Underpinning of existing foundations is particularly common when new construction occurs nearby.
