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.

ODOT's Office of Materials Management, the Federal Highway Administration, and the Industrial Resources Council are co-sponsoring the upcoming Ohio Sustainable Roadway Materials Workshop, which will be held December 3 at ODOT central office in Columbus, OH. This FREE workshop will provide information and resources to help agencies, engineers, project designers and contractors make sustainable material choices to comply with FHWA's recycling policy. The agenda and listing of speakers can be found at http://industrialresourcescouncil.org/ohsrm

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.

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.

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.

Based on the popularity of our previous two Blue Jackets outings, we, in conjunction with ASHE and Engineers Club of Columbus, have a group package of 50 tickets to the Blue Jackets-Hurricanes game. Tickets are $10 per member and $15 per guests. We're accepting pre-payment using PayPal. As these tickets usually sell for $50 face value, it's a great deal. Prior to the game, we’ll have a social put on by the Younger Members group at Brother's, so even if you don't want to go to the hockey game, please come out for drinks, food, and fellowship.

More than 250 experts from 30 states and 19 state departments of transportation attended the first two International Conferences on Perpetual Pavement (ICPP), held in 2006 and 2009, to discuss optimal design and construction approaches for asphalt pavements designed and built to last longer than 50 years without requiring major structural rehabilitation or reconstruction, and needing only periodic surface renewal in response to distresses confined to the top of the pavement.

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