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.

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
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.

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.

The November 2014 newsletter is now available for download.

The Ohio State University Department of Civil, Environmental & Geodetic Engineering announces the introduction of structures graduate-level courses beginning at 4:00 PM that may be of interest to Central Ohio working professionals. These courses start in the Spring semester of 2015 and include:

• CIVILEN 7330 Earthquake Engineering
• CIVILEN 7332 Advanced Behavior and Design of Metal Structures

Additional information may be found the University’s College of Engineering website at https://ceg.osu.edu/graduate.

Topic: SR33/I270 Interchange

Joint meeting with ASHE
(Online registration and payment available, see bottom of page.)

The reconstruction of the I-270/US 33 interchange was identified as an intermediate project in the I-270/US 33 Northwest Freeway Study (NFS), completed by the Mid-Ohio Regional Planning Commission (MORPC) and the Ohio Department of Transportation (ODOT) in 2006. Eight conceptual alternatives were developed and studied to improve traffic operations, promote economic growth and eliminate hazardous crash areas while minimizing environmental and right-of-way impacts. The interchange improvements will be constructed in phases, with Phase 1 construction beginning in 2015 and Phase 2 construction approximately 15 years after completion of Phase 1.

Please join ASCE, ASHE, OSPE, Engineers Club, EWB, & WTS for a happy hour after OTEC. It is sure to be a great networking event.

Purpose and Background
Cut walls (top down construction) have a wide range of applications and encompass a diverse range of wall families including sheet pile, post and panel, H-pile and lagging, slurry and soil mix. These walls resist lateral earth and water pressures through their structural stiffness and anchorages. The LRFD platform offers a rational framework for consideration of different types of walls. This webinar will use the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge and Structures Specifications as a basis for the technical content. Applicable articles in Sections 11, 10 and 3 of the 6th Edition (2012) of AASHTO LRFD Specifications will be used as a basis of discussion.

The webinar will assume that the participant has a basic working knowledge of design and construction of cut retaining walls including fundamental aspects of earth pressure theories and earth pressure diagrams. It will include discussion on the terminology and types of cut walls, lateral earth pressure design approaches for cut walls, applicable load factors, use of minimum and maximum load factors for permanent loads, permanent and transient surcharge loads, identification of limit states and resistance factors, pressure surfaces for geotechnical and structural analysis, and consideration of extreme event limits state such as scour and seismic events. Introductory information on ground anchor application, construction and design of ground anchor walls in the context of limit states and general concepts will also be presented. A standalone webinar on ground anchor walls addresses the application of ground anchors in all types of cut walls in more detail.

Purpose and Background
Fill walls have a wide range of applications and range in configuration from the basic gravity and cast-in-place (CIP) semi-gravity walls to complex mechanically stabilized earth (MSE) walls. The LRFD platform offers a rational framework for consideration of different types of fill walls. The webinar will use the 6th Edition (2012) American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge Design Specifications as a basis for the technical content. Applicable articles in Sections 11, 10 and 3 of the AASHTO LRFD Specifications will be used as a basis of discussion.

The webinar will assume that the participant has a basic working knowledge of design and construction of fill retaining walls including fundamental aspects of earth pressure theories. The webinar will include discussion on the terminology and types of fill walls, lateral earth pressure theories for fill walls, permanent and transient surcharge loads, applicable load factors, use of minimum and maximum load factors for permanent loads, identification of limit states and resistance factors, pressure surfaces for geotechnical and structural analysis, and consideration of extreme event limit states such as seismic events.

The webinar will concentrate on external stability of CIP and MSE walls. Introductory information on internal stability of MSE walls in the context of limit states and general concepts will also be presented. A standalone webinar on MSE walls addresses MSE walls in more detail.
