Dynamically Loaded Machine and Equipment Foundations - A Design Primer

Date & Time: 
Mon, 03/30/2015 - 12:00pm - 1:30pm
Location: 
E.L. Robinson Engineering, 1801 Watermark Drive, Suite 310, Columbus, OH 43215

*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch

Machinery and equipment typically found in industrial and process facilities often exert dynamic loads on their foundations. Designing these foundations is quite complicated, much more so than the design of the foundations that support buildings and statically loaded equipment. (The latter is addressed in the companion ASCE webinar, Design of Foundations for Equipment Supports.) This topic is rarely, if ever, included in the engineering college curricula, and the engineers are left to learn on the job. Yet the stakes are high: The failure of an incorrectly designed machine foundation can lead to damaged equipment and to expensive downtime. This webinar provides a practical introduction to the complex issues of designing dynamically loaded machine and equipment foundations.

Purpose and Background
Many engineering firms that specialize in the design of industrial facilities and heavy-equipment foundations have developed a wealth of in-house design standards, but this information is not available to others. As a result, and because of the design complexity involving dynamic analysis and specialized software, some engineers have resorted to simplistic rules-of-thumb without understanding the limitations of such shortcuts.

Calculation and Use of Time of Concentration

Date & Time: 
Fri, 02/27/2015 - 12:00pm - 1:00pm
Location: 
Stantec, 1500 Lake Shore Drive, Suite 100 Columbus, Ohio 43204

*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch

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.

Sustainable Transformation/Rehabilitation of an Urban Corridor

Date & Time: 
Tue, 02/10/2015 - 12:00pm - 1:30pm
Location: 
Burgess & Niple, Inc., 5085 Reed Road, Columbus, OH 43220

*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch

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.

Engineers Without Borders Central Ohio Professionals Chapter

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.

Design of Foundations for Equipment Support

Date & Time: 
Fri, 01/23/2015 - 11:30am - 1:00pm
Location: 
E.L. Robinson Engineering, 1801 Watermark Drive, Suite 310, Columbus, OH 43215

*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch

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: Blueprint Clintonville Integrated Solutions Project
Pilot Area Technical Committee (PATC) - Approach and Interim Findings in Columbus, Ohio

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

The City of Columbus, Department of Public Utilities, Division of Sewerage and Drainage (the City) has embarked upon its approved Wet-Weather Management Plan (WWMP). Currently, that plan is almost entirely comprised of a series of treatment plant capacity upgrades, storage tanks, tunnels, and other piping system augmentations; collectively known as “gray” infrastructure. After approval of the WWMP, the use of more renewable, sustainable, and environmentally friendly systems, commonly referred to as “green” infrastructure, has been recognized and implemented in many communities as a potential solution to many of the elements associated with consent order requirements.

Recently, the City received approval from Ohio EPA to delay many elements of the WWMP so the City can investigate whether it can meet the WWMP goals and future stormwater regulations with green infrastructure and I&I control on public and private property. The solution is known as the Integrated Solution (IS). The City is proceeding forward with the pilot for this Integrated Solutions approach in the Clintonville neighborhood. 

This presentation will discuss the efforts of the Pilot Area Technical Committee (PATC) charged with developing and refining the project objectives, as well as the methodology and logistical challenges of achieving these goals.
