1. Technical Services By Nathan Haaland

2.  Increase in Construction Costs  Asphalt  $350 to $735 per ton  Labor  3.6% increase  Inflation  13% increase

3.  Increase in Construction Costs  Concrete  3.3% increase  Steel  24% increase in last 4 years  Diesel  55% increase

4.  Special Project  Design Division  Environmental and Transportation Services  Materials and Research Division  Bridge Division

5.  Special Project  Evaluated individual projects  October Bid Opening  November Bid Opening  February Bid Opening  Thin Lift Overlay, Slurry Seal, Micro Surfacing and Seal Coat Projects

6.  October Bid Opening and November Bid Opening  All projects were independently evaluated by a team of individuals

7.  February Bid Opening  All projects were independently evaluated  Preventative Maintenance Projects

8.  Thin Lift Overlay, Slurry Seal, Micro Surfacing and Seal Coat Projects  All projects were evaluated according to the Highway Performance Classification System

9.  Decision Document  Office Holders Recommendations  Deputy Director of Engineering Decision

10.  Sub-Grade, Base and Topsoil  Edge Drain  Controlled Density Backfill  Topsoil Thickness  Shoulder Preparation

11.  Sub-Grade, Base and Topsoil  Edge Drain PROSCONS CostWith the clay soils, it could create a holding area for water that cannot drain Water moves very slowly through Non- Permeable Base(Salvage Base) City requests the edge drain system Cheap Insurance(to protect Subgrade)

12.  Sub-Grade, Base and Topsoil  Controlled Density Backfill PROSCONS CostThe pipe standards are changing and this may be eliminated with the new standard drawings for pipe Backfill the same day as the pipe is placedThe smaller size pipe tends to move when compaction takes place with a tamper/compactor. The flat pipe grades required will not drain if the pipe moves

13.  Sub-Grade, Base and Topsoil  Topsoil Thickness PROSCONS CostThinner top soil layer

14.  Sub-Grade, Base and Topsoil  Shoulder Preparation PROSCONS CostNon-aesthetically pleasing shoulder

15.  Pavement  FAA  PG Oil Type  Shoulders  Entrance Ramps  Pavement Width  Pavement Thickness  Prime Coat  RAP

16.  Pavement  FAA PROSCONS CostDecrease Design Life Safety issues with existing rutting Increase Rutting and shoving

17.  Pavement  PG Oil Type PROSCONS CostIncrease Rutting Increased Pavement Shoving Decreases the ability of the Asphalt to flow

18.  Pavement  Shoulders PROSCONS CostAesthetics – New PCC vs. Old PCC No change structurallyWill Delay Bid Opening

19.  Pavement  Shoulders PROSCONS CostPaved shoulders on North and South ends of project Will Delay Bid Opening

20.  Pavement  Entrance Ramps PROSCONS CostOnly one entry lane Follows Design StandardsWill Delay Bid Opening

21.  Pavement  Pavement Width PROSCONS CostFuture TLO Projects Following Design Guidelines

22.  Pavement  Pavement Thickness PROSCONS CostShoulders not protected Decrease Design Life by 5 years and reliability by 10%

23.  Pavement  Prime Coat PROSCONS CostPrime coat will only hold aggregate for 1 year Lower unit cost by adding multiple projectsHBP needs to be placed in 1 year Low Volume roadNo HBP surface with new bridge No surcharge is required and some settlement will occur Aesthetics

24.  Pavement  Prime Coat PROSCONS CostAesthetics Easier to MaintainTemporary Bypass is not sealed Low Volume road

25.  Pavement  RAP PROSCONS CostInconsistent RAP material Use of existing materials 20% RAP use will decrease AC content by 1%

26.  Miscellaneous Construction  Median Paving  Shared Use Path  Guardrail  Concrete Reinforcement over Pipes  Jersey Barrier  Joint Resealing

27.  Miscellaneous Construction  Median Paving PROSCONS CostAesthetics No change structurallyThe 2’ width colored brick pattern behind the curb provides a visual separation of the pedestrian from the vehicle traffic

28.  Miscellaneous Construction  Shared Use Path PROSCONS CostIs not consistent with the 10’ widths on existing Shared Use Paths 8’ is recommended only when the Shared Use Path has limited use Will Delay Bid Opening

29.  Miscellaneous Construction  Guardrail PROSCONS CostWeed Control Aesthetics More Maintenance is required

30.  Miscellaneous Construction  Concrete Reinforcement over Pipes PROSCONS CostPossible settlement over pipe areas

31.  Miscellaneous Construction  Jersey Barrier PROSCONS CostPossible headlight glare Less of a snow trapInconsistent with the 42” height recently constructed on I-29 urban corridor in Fargo Existing concrete barrier on I-94 is 32”Will Delay Bid Opening

32.  Miscellaneous Construction  Jersey Barrier PROSCONS CostProject will be constructed in 2 phases Safety for Workers

33.  Miscellaneous Construction  Joint Resealing PROSCONS CostUnsealed Joints Pavement is approximately 30 years oldShortens life of pavement CPR is a short term fix onlyWeakens sub-grade

34.  Miscellaneous Construction  Detection Loops  Signal Heads  Decorative Lighting

35.  Miscellaneous Construction  Detection Loops PROSCONS CostAesthetics - Future loops will have to be sawed and other loops are placed below pavement surface with the concrete reconstruction project

36.  Miscellaneous Construction  Signal Heads PROSCONS CostInconsistent with existing signaled intersections within the city

37.  Miscellaneous Construction  Decorative Lighting PROSCONS CostIt is not consistent with existing conditions Will Delay Bid Opening

38.  Location of Decision Documents  FileNet

39.  Implemented to evaluate individual projects on ways to save money  Offset rising Construction Costs  Uncertain future of the Highway Trust Fund.
