For Asset Management

Transcription

1 For Asset Management By: Larry Weiss SDLTAP It Begins with Accurate Inventory Inventory of existing system: The Local Roads Needs Study conducted in Aug/Sept of 08 indicated by it s results and from LTAP visits that inventory information is limited to non existent in some cases. This is essential information from which to plan especially for annual budgeting and for making longer term decisions. 1

2 Starting the Process of Inventory Location of existing culverts and small structures Size Length Diameter Fill Depth Slope Condition Rating system Excellent Good Fair Poor Needs Replaced Priority Purpose of Inventory To know the condition of our culverts To plan for future projects Added costs Doing it right the first time Make sure we have the pipe needed on hand or ordered Replace what is bad before we begin a street project Especially if it is a hard surface project To complete the project in a timely and cost effective manner 2

3 Pipe Maintenance Determining needs from timely inspection reports Reacting to the inspection reports Guidance in maintenance procedures and methods Repair vs replace CONCRETE CULVERTS BOX OR BARREL HEADWALLS DETERIORATION JOINT SEPARATIONS CRACKS SETTLEMENT EROSION/SOIL LOSS AROUND PIPE CLEANING NEEDED 3

4 What Are We Looking For? Deterioration of the pipe Rusting through Seems or bands coming apart Concrete failure Common failures End sections tipping or falling off Erosion Undermining Collapsing Settling Sediment and debris causing reduced or no flow Flared Ends Safety Ends Beveled for Trash Type of Pipe Items of Importance CMP or Concrete Round Arched Box 4

5 Method To Be Used Visual and hand written evaluation Use of a contractor ( Engineering Company) Visual and electronic submission of data GPS device with notes Juno device No method (common method in smaller cities) Replace after failure (also common) Planning for the future The JUNO System Hand held electronic device (around $850 State Contract) It is a full service device GPS location of center and both ends Stores pipe dimensions Drop down box for condition Has condition box that can be checked Capable of taking and attaching pictures Miscellaneous screen for making notes Can also be a good tool for street signs ect. 5

6 Hand Written Method Pros: Very effective Easy to use Understandable Easy to Learn Cons: Need to attach photos Time consuming Another file of cumbersome papers CULVERT INSPECTION CHECKLIST LOCATION: STRUCTURE NO: _ DATE: /INSPECTED BY: SIZE,LENGTH,TYPE: GPS COORDINATES: ITEM GOOD OR NEEDS COMMENTS COND. REPAIR METAL CULVERTS Rusting/Corrosion Connections Settlement Erosion/Soil loss around pipe Cleaning needed CONCRETE CULVERTS Box or Barrel Headwalls Deterioration Joint Separations Cracks Settlement Erosion/Soil loss around pipe Cleaning needed 6

7 Conclusion Must be used in some form to make cost effective and responsible decisions A way to communicate with your council as to your needs looking forward A means to track repairs and maintenance as completed As a budgeting tool To prevent damage in the future Both property and infrastructure Sign Inventory Paper Method 7

8 What must we know Sign inventory number Location (GPS Location) Sign type (R1 1 R1 2 W11 19 W2 4 MUTCD#) Size of sign (30X30 36X36 12X36) Post type (round square U channel Metal Wood size of post 2x2 4x4 4x6 telspar) Height Lateral offset continued Sheeting (engineer grade diamond grade ect.) Reflectivity (night time or reflectometer) Sign facing direction ( east west north south) Condition of sign ( sign blank sheeting post) Needs (repaired or replaced or OK) Is it the proper sign Take a photo (proves the sign was up) 8

10 LOOKING FORWARD FOR SUCCESS BY: Beau Riopel BACKGROUND INFO Nearly 80 miles of roadway surface (excluding alleys) 73 Miles are Bituminous 4.5 Miles of gravel.35 Miles of concrete pavement 24 Miles are considered arterial or collectors 26 Miles are considered residential City increases their system inventory by 1.25% yearly Equates to 13.6 new miles in 17 years Currently working from a 5 year capital outlay plan 10

11 CURRENT MAINTENANCE PLAN Fixed budget driven maintenance program A basic mill and fill program Very limited Budget for crack sealing and patching PLANNING FOR THE FUTURE Implement a street maintenance program Include current maintenance and future growth Look at what other agencies are using Principals that will work for Spearfish Develop a strategic map of our needs Use these tools to develop a working budget Develop a plan the City Council can grasp moving forward and is understandable to the public 11

12 RESEARCH METHOD CHOSEN Determine how long our current roads are lasting Determine maintenance needed to current roads How long before each road needs a major rehab Gain these numbers by adopting the Army Corps of Engineers PCI method 2013 will be the first of using PCI and we are in hopes it will help us in implementing a long range plan for maintenance, new construction, and rehab time tables EXPANDING OUR MAINTENANCE Need for more aggressive crack sealing Need for more chip sealing Looked into micro surfacing but found the cost of this due to no contractors in our area that perform this was very cost prohibitive We are also looking to add flush sealing and fog sealing to our tool box The need for increasing our number of annual street improvement projects 12

13 BUDGET INCREASES 2012 Our SI projects cost were $800,000 Increased maintenance budget from $80,000 to $155,000 with an additional SI project 2013 $1.8 million on joint project with county Small projects estimates are $175,000 + $25,000 additional for crack sealing 2014 Capital outlay of $2.5 million 2015 Capital outlay of $2.8 million CONTINUING IMPROVEMENTS Crack Seal and chip seal within 2 5 years of a major project completion Continue looking at micro surfacing or an alternative as budget allows Keep looking for newest methods available that are most cost effective for our City Some of these methods may include in place processing and reclamation as well as AC cement, soil and base stabilization 13
