RECENT POLICY CHANGES IN THE EPG

Maintenance Worker Marc Jackson (left) practices a pre-trip inspection with Darnel DeBoise (right), a student earning his commercial drivers license at St. Louis' Westlake training site. Shari Dye, NE District Safety and Health Manager, discusses the contents of a chemical's container with Elsberry Maintenance Supervisor Roy Niemeyer during his building's annual environmental inspection. 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. Millions of 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. Checking plans on the Chestnut Expressway/Rte. 65 Diverging Diamond Interchange project, Springfield's newest DDI, are Resident Engineer Brad Gripka, left, and Sr. Construction Inspector Craig Huckaby. Keith Zey, a Central District Maintenance Crew Leader, became the first Safety Jackpot winner. Safety Jackpot is one of the first new programs promoting a safe work environment. This incentive program rewards excellence in safety. Perhaps you've wondered how many hits the most popular EPG articles have. As of late August, the numbers of hits are: 20. EPG 136, 44421 10. EPG 903, 76555 19. EPG 1000, 56588 9. EPG 616, 93950 18. EPG 903.5, 60863 8. EPG 616.23, 106277 17. EPG 751.13, 62773 7. EPG 200, 107185 16. EPG 751.5, 64074 6. EPG 600, 129842 15.

Anchor Bolts Used on Weathering Steel Bridges 8/28/12: Bridge has clarified some the H3c and d Bearings Standard Detailing Notes to change the requirement for anchor bolts used on weathering steel bridges to coated with inorganic zinc primer. Also, in numerous notes and figures, especially in EPG 751.11.3 Details, "rod" was changed to "bolt", as in "anchor bolt". Full Depth Pavement Repair Dowel Bars 8/28/12: New guidance instructs designers calculating quantities for full depth repairs that each dowel bar is to be counted separately as a pay item, regardless of whether being drilled into a slab or placed as part of a dowel basket with other bars. Links to Free Web-based NHI Training 8/27/12: Links to NHI's Transportation Curriculum Coordination Council courses are now available at EPG 106.18 Technician Certification Program. Overcoating Existing Steel Standard Detailing Notes 8/24/12: Three paint notes were modified, primarily revising an existing note that prime coat shall not be required for calcium sulfonate overcoating projects. Two Updated QRGs 8/23/12: Change Orders – Value Engineering and Job Order Contracts were updated. Widening and Repair of Bridges 8/23/12: Bridge has updated numerous figures in EPG 751.40.2.4.1 Cast-In-Place Deck With (and Without) an Existing Wearing Surface, Hydro Demolition to match the standard plans. Consultant Contract Invoicing 8/22/12: The invoice template guidance was clarified and slightly expanded in EPG 134.5.1 Invoicing. Mulch Overspray 8/20/12: An acceptance statement was added to clarify the method of acceptance for mulch overspray. Girder/Beam Chairs and Concrete Pile Cap Integral End Bents 8/14/12: Bridge Division has clarified guidance for girder chairs and for reinforcement of concrete pile cap integral end bents. Table 1020.4.17 Tensile Strength of Lock Seams 8/9/12: This table's values have been updated to conform with AASHTO and ASTM standard practices. EPG 751.2.1.1 Dead Load 8/9/12: The table of unit weights of dead load was updated to conform with AASHTO Table 3.5.1-1. Safety EdgeSM 8/3/12: A Safety EdgeSM constructed at the edge of each shoulder has been added as a minimum expectation for minor route shouldering projects. Copying Detailing Notes 8/2/12: Bridge has produced directions on how to copy detailing notes from the EPG to MicroStation drawings. Minor Routes Shouldering Project Guidelines 8/2/12: Since the public perceives shoulders as an enhancement to the transportation system and consistently identifies them as a top tier desire, this new article facilitates the design of shoulders for minor routes. EPG 139 Design-Build 7/31/12: Guidance for the procurement process and implementation procedures has been expanded in this article. Two Updated QRGs 7/31/12: Contract Adjustments and Line Item Adjustments were updated. New Adopt-A-Highway Signs 7/26/12: New guidance has been added to EPG 903.9.6 for the updated signs. Sequential Flashing Warning Light 7/26/12: Fig. 616.6.83 has been added for additional guidance. New Guardrail Height Requirement 7/25/12: Guidance was revised with the new guardrail height requirements per FHWA and AASHTO. New height requirements were also provided for using guardrail with urban sections of curb and curb and gutter. Innovative Contracting 7/25/12: This new article includes guidance for Add Alternate Bidding (additional items of work that the contractors all bid on and may be awarded if the bids come within the budget specified in the bidding documents), Job Order Contracting (JOC) (a procurement process that allows MoDOT to award fixed price construction contracts with indefinite delivery and indefinite quantities at individual work locations throughout the project limits) and Alternative Technical Concepts (a proposed change to agency-supplied base design configurations, project scope, design criteria or construction criteria that provides a solution that is equal or better to the requirement in the contract). EPG 450.9 Safety Edge 7/25/12: New guidance for Safety EdgeSM. This concept consists of beveling the edge of an HMA pavement during placement, to provide a smooth height transition for future errant vehicles to regain the roadway. The Safety EdgeSM is easy to construct, uses very little additional material, and has the residual benefit of increasing the compaction of the edge. Sequential Lighting 7/25/12: EPG 616.6.63 and EPG 616.6.83 were revised to accommodate sequential lighting which allows traffic, especially large trucks, to enter the work zone in a safer manner. Lateral Placement of Guard Cable in the Median 7/25/12: The parameters were clarified for lateral placement of high-tension cable barriers in medians that are 30 ft. or wider. TM-64 and TM-67 7/24/12: Both TM-64 and TM-67 are no longer valid and were deleted from Material Inspection Test Methods guidance. EPG 236.5.18 Categorical Exclusion Review 7/23/12: Guidance was updated to allow the review time for a Categorical Exclusion to be extended from 1 to 3 years.
