| RECENT POLICY CHANGES IN THE EPG | |||||||||||||||||||||||||||||||
MoDOT has made great strides to build a good transportation system and increase taxpayers' trust in its ability to deliver what was promised. Innovative concepts, such as Practical Design and design-build, were used to deliver those commitments and have made MoDOT a leader in the transportation industry. These forward-thinking, innovative concepts are reflected in the ENGINEERING POLICY GUIDE (EPG). This document provides a single reference for all engineering and engineering-related guidance by combining the former Right of Way, Design, Bridge, Construction, Traffic and Maintenance manuals. MediaWiki, the engine behind the Wikipedia on the World Wide Web, is the software delivering the EPG. Over 30 million hits on the EPG endorse this format to be easy to navigate and pleasing to read. A small HELP ARTICLE is included to assist with helpful hints on how to use the EPG as well as other points of interest.

Standard Detailing Notes on Bridge Standard Drawings for Prestressed Panels 9/10/15: New references to prestressed truncated end deck panels have been added. EPG 617.1.1 Temporary Concrete Traffic Barrier – Type F 9/9/15: Guidance for Temporary Concrete Traffic Barrier Standard Drawings now reflects recent crash studies. Of particular note, the Midwest State's Regional Pooled Fund Research Program Report TRP-03-113-03 (revised) recommends the design deflection limit for free standing (unpinned) temporary traffic barrier be set at 2 feet. This would reduce instances in which temporary traffic barrier would require pinning. EPG 606.1.3.2 Approved Crashworthy End Terminals 9/9/15: Previously, a contractor would typically choose the cheapest end treatment from the approved list and provide that unit whether it was the best solution or not. For that reason, end treatments are now further subdivided to more closely match the hardware to its intended use, performance, reusability and cost of repair. Determination of the International Roughness Index 9/9/15: Guidance now codifies the intent that no filters may be used to distort the true road profile measurement with an inertial profiler. Airport Requirements 9/9/15: Guidance in EPG 235.8 Airports now details the requirements for Obstruction Evaluation/Airport Airspace Analysis that ensure that FAA filing requirements are met when MoDOT operations impact FAA airspace. EPG 133.4 Snow and Ice Control Operations 9/8/15: Guidance for non-continuous operations routes and plowing was clarified. It has never been intended to meet objectives on the non-continuous treatment routes "as soon as possible". Rather, operations on these routes may be suspended overnight and at times when progress is not being made. EPG 751.50 Standard Detailing Notes 9/8/15: Clarified numerous notes and revised the Bridge Approach Slab Notes to match the recent release of new Bridge Approach Slab std. drawings. Series I Protective Coating 8/28/15: Guidance in EPG 751.14.5.8 Protective Coating Requirements and EPG 751.50 Standard Detailing Notes A4. Protective Coatings was revised to conform to Sec 1081, clarifying when to use System I. Alternate Paving Minimal Thickness 8/27/15: Guidance was clarified to indicate the minimal thickness of pavement must be 7" for a Life Cycle Cost Adjustment to be applied. EPG 129.4 Coordination with other Agencies 8/25/15: Guidance was clarified about the list of agencies with whom to coordinate the environmental process. 8/25/15: Guidance about contractor's surety has been clarified since contractor surety has not been necessary for some time. Illicit Discharge Detection and Elimination (IDDE) Fact Sheet 8/24/15: This helpful document is available at EPG 127.29.5 MCM 3: Illicit Discharge Detection and Elimination. 8/19/15: This new subarticle updates EPG guidance to current practice for concrete design. EPG 806.7.6 Pollution, Erosion and Sediment Control Basis of Payment 8/17/15: To maintain compliance with the Consent Decree's requirements, erosion control change order guidance has been provided. 8/11/15: Guidance was updated in EPG 109.12 Change Orders because the EPA is now mandating the Stormwater Compliance and Environmental Specialist be able to execute change orders up to $100,000 for erosion control items. ET-Plus Policy 8/7/15: In EPG 606.1.3.1 3R/4R Projects, guidance now requires ET-Plus end treatment devices to be replaced during construction or repair, including anytime existing adjacent guardrail is raised or the end treatment modified. Concrete Coring 8/6/15: In several locations in EPG 751 LRFD Bridge Design Guidelines, references to concrete coring of drilled shafts were removed because it is no longer specified on a set of bridge plans for integrity testing of drilled shafts. During construction, concrete coring may still be called for by the engineer when there is a dispute with the sonic logging testing. Geometric Layout of a Diamond Interchange 7/31/15: In EPG 234.2.1.1 Ramp and Preliminary Plan Criteria, the 700 ft. dimension between ramp termini previously shown in this diagram was revised to 800 ft. to reflect recent USDOT/FHWA guidance. EPG 236.3.7.5 Distribution of Clearance Certification 7/24/15: Guidance has been provided for loading documents into RWPA. Work Zone Questions for the Core Team 7/23/15: This new list has been produced to aid PMs and the core team to develop the WZ JSP and to identify early on the WZ impacts. It is available in EPG 616.14.3.2.4 Project Core Team. PCC and Superpave Smoothness 7/22/15: Guidance about PCC and Superpave concerning smoothness in EPG 403.1.17 Quality Control, EPG 403.1.21 Basis of Payment and EPG 502.1.8 Surface Test was revised to comply with Sec 610. Engineering Policy Group Ballot Cycles 7/17/15: The ballot cycle dates have been updated. New RW Form 7/15/15: The new Property Owner Opinion Survey will help property owners show how MoDOT representatives performed their job of acquiring property rights and, perhaps, indicate possible future improvements. Fatal Crash Reviews 7/15/15: Fatal crash reviews are now an optional regional council process. EPG 907.6 Fatal Crash Reviews has been removed. Composite Design for Steel Superstructures 7/9/15: In EPG 751.10.2.1 Precast Prestressed Concrete Panel Forms - Design and especially in EPG 751.14.4 Composite Design, guidance and details about making steel girders and beams composite were added. |
