RECENT POLICY CHANGES IN THE EPG

Sr. Construction Inspector Craig Huckaby prepares a sample of concrete for testing at the new Diverging Diamond Interchange under construction at U.S. 65 and Battlefield Rd. in Springfield. Customer Service Rep. Tonya Staeger (center) recognizes volunteers at the MO Dept. of Conservation Nature Center for their participation in the Adopt-a-Highway program. Volunteers pick up trash along Nature Center Way in Springfield and have gone out twice each month to do so since 2003. Resurfacing, shoulder improvements and a curve improvement are all part of the Rte. U project in Lincoln County. Here at Sand Run Rd., the contractor, Mid-River Asphalt, is softening the curve. 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. Sr. Maintc. Worker Justin Fagre provides temporary traffic control during recent culvert pipe repair work on Rte. AA in Maries County. Perhaps you've wondered how many hits the most popular EPG articles have. As of mid-August, the numbers of hits are: 20. EPG 903.6, 119153 10. EPG 616, 168233 19. EPG 134, 122159 9. EPG 600, 201947 18. EPG 751.50, 123204 8. EPG 616.23, 215327 17. EPG 136.4, 129085 7. EPG 101, 230996 16. EPG 751.40, 129693 6. EPG 100, 249365 15. EPG 751.5, 136036 5. EPG 136.12, 254773 14. EPG 620.2, 138395 4. EPG 700, 256909 13. EPG 136.9, 144814 3. EPG 900, 278514 12.

EPG 806.7.6 Pollution, Erosion and Sediment Control Basis of Payment 8/17/15: To comply with the Consent Decree, erosion control change order guidance has been provided. Erosion Control Change Orders 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. Construction Inspection Guidance for Temporary Stream Crossings 7/9/15: Guidance was updated to bring it into compliance with Sec 303.2. Pavement Marking Guidelines 7/8/15: The types of paint available to contractors has been clarified in this table. A diagram, "Pavement Marking Material Decision Tree for Design Projects", was also added. EPG 109.12 Change Orders 7/7/15: Under MoDOT's agreement with FHWA, Level 2 change orders will also be sent to FHWA for review.  Custody of QA Cores 7/1/15: In EPG 403.1.19 Acceptance of Material and EPG 502.2 Material Inspection, guidance has been updated to show that tamper-proof bags will be used when the MoDOT project inspector could not maintain full-time possession. EPG 143.2 Practical Design Concepts to Consider 6/30/15: This new guidance leads designers to consider typical items during project design to produce a practical application of radical cost control. EPG 106.3.2.86 TM-86 Preparation of Samples for Surface Sealer Wet Track Abrasion 6/30/15: This is a new MoDOT Test Method. Seal Coats and Contracting Level Coats 6/26/15: The CLC and Seal Coat guidelines and JSP packages were updated. Guidance in EPG 409.1 Design now provides contractor flexibility and increases the potential usage of seal coats. Guardrail Height 6/25/15: Guardrail adjustment height requirements has been clarified. The minimum height after adjusting/replacing blocks is 27 ¾ inches. Bridge Approach Slab 6/22/15: In EPG 503 Bridge Approach Slabs, EPG 611.1.1 Design, EPG 748.7 Bridge Deck and Bridge End Drainage, EPG 751.1 Preliminary Design and EPG 806 Bridge End Drainage, two new designs of bridge approach slabs were implemented. The new designs reduce construction costs while maintaining current performance. Significant clarifications and drawing maintenance are also included in this change. EPG 751.22.3.13 Intermediate Diaphragms 6/22/15: Guidance has been brought into compliance with the standard drawings. EPG 152 Contactor Bonding Responsibilities 6/19/15: This new article provides guidance about bid, performance and payment bonds and how surety companies are involved with these bonds on road and bridge contracts. J. MSE Wall Notes (Notes for Bridge Standard Drawings) 6/17/15: These general notes were revised to clarify wedge requirements for the area behind soil reinforced zone. Also, design options were given to designers to achieve more economical results.
