10. Hydraulics, Item 611 Summary Jeffrey Syar, Administrator Office of Hydraulic Engineering

11. Item 611 PIPE CULVERTS, SEWERS, DRAINS, AND DRAINAGE STRUCTURES
This is a Performance Based Specification that encompasses 2010 items: 603, 604 and SS 802.
SS 802 is now item 611.

12. Why Change?
Method based specifications were being faulted when conduit was poorly installed by the Contractor
Resulted in the Department accepting poorly installed conduit or incurring additional costs during construction

13. Background
1997 – SS802 optional performance based installation specification included on all projects with 603 and 604.

14. Background
2008 SS 802 was revamped with the intent of developing a performance based standard specification
2009 SS 802 was required on a number of projects state wide in an attempt to pilot the specification.
2012 Projects that are sold after March 31, 2012 and have any Item 603 or Item 604 work and have a construction cost estimate of 10 million dollars or more.
2013 Implement C&MS 611 (Page 471)

15. General Differences
The contractor develops and executes his own installation plan for all conduit and drainage structures.
Requires documented coordination between the material supplier and the installer.

16. General Differences (cont’)
Conduit and drainage structures require both Installation and Performance Inspection that is tied to payment.
Contractor is required to repair or replace conduits and drainage structures that do not meet the performance requirements.
611 Substantially expanded the acceptable inspection methods and equipment versus SS 802.

17. How it works
Contractor selects the drainage component materials allowed by contract (as shown in the plan).
Contractor develops an installation plan appropriate for the materials selected.
Contractor installs, monitors and documents the installation.
Based on contract criteria, the Contractor provides inspection / 3rd party evaluation and certification of Performance.

18. Conduit
Conduit shown in the plans is designed for hydraulic capacity and durability only
Structural design is performed by the Contractor in coordination with the conduit Manufacturer

19. Submittals Shop Drawings Installation Plan
Construction Inspection Forms
Performance Report

20. Shop Drawings
Have a Registered Engineer prepare, sign, seal and date all calculations. Second Registered Engineer checks and seals the submittal as well.
Allow at least 15 days for the review.
Note:
D load special design reinforced concrete pipe
Concrete precast 3 sided, arches and round sections
Substitutions involving box culverts and or 3 sided, arches and round sections.

21. Installation Plan Trench dimensions
Identify locations where the conduit is installed in a
cut installation
fill installation
Type of bedding and backfill material with lift thickness
Compaction density and equipment proposed for bedding and backfill
Identify the starting location for each run of conduit
Maximum allowable joint gap between conduit sections
Other installation details as necessary

22. Installation Plan (cont.)
Provide written confirmation from the conduit manufacturer that the pipe material and strength supplied are appropriate for the material and density requirements described in the installation plan regarding backfill and bedding as well as height of cover. This confirmation by the conduit manufacturer will not relieve the Contractor of the responsibility for obtaining the required results.

23. Construction Inspection Forms
Perform work only in the presence of the Contractor’s representative doing the inspection. Submit construction inspection forms to the Engineer for each run of conduit and each drainage structure.
Form CA-P-1 for conduit
Form CA-P-3 for drainage structures.  
“I certify that the information on this form is accurate and all deviations from the current installation plan have been noted.”

24. Performance Report
Performance report required for each Performance Inspection
Separate report for each change in conduit size or change in material type
Report includes the following:
Project information
Date of inspection
Type and size of conduit
Conduit diameter report from the Manufacturer
Time of video recording
Location – latitude and longitude where conduit crosses centerline of roadway – for culverts
Summary of all defects and locations
Size of Mandrel and how the size was calculated if using Mandrel

25. Performance Report
Submit performance report within 5 days of completing a performance inspection to the Project Engineer

26. Performance Inspection
Notify the Engineer at least five workdays before conducting a performance inspection.
A performance inspection is not required for projects that meet all of the following:
All conduit is Type C (Sewers not under pavement)
Conduit plan quantities are less than 100 feet
All conduit has less than 16 feet of maximum fill height

27. Performance Inspection (Cont’)
Inspection is performed between days after: the
completion of the finished grade when not below pavement
after the completion of the aggregate base when below pavement.
after completion of conduit correction
Engineer may adjust this time frame if the contract duration will not permit a 30 day waiting period.

28. Performance Inspection (Cont’)
Inspection required for Conduits and Drainage Structures
Inspection required for any conduit that requires correction
Inspection may be performed by Contractor
Ensure the Project Engineer is present during all performance inspection activities
Project Engineer must be notified at least 5 workdays before conducting a performance inspection

29. Manual or Remote Inspection
Either Manual or remote inspection are required to measure cracks, deflections, and joint gaps in conduit.
Conduits with a rise 48 inches and greater  Manual Inspection
Conduits with a rise of 36 to 48 inches  Manual or Remote Inspection
Conduits with a rise of 12 to 36 inches  Remote Inspection
Drainage Structures are inspected Manually

30. Manual Inspection
Manual inspections require entering the conduit or drainage structure to record video and to make measurements - coordinate confined space access per OSHA requirements.

31. Remote Inspection
Use a crawler mounted camera to record video with the equipment described in Supplemental Specification 902.
Remove all debris from the conduits being inspected according to Dewater the conduit if the water level hinders the performance of the equipment.

32. Conduit Inspection - Flexible Conduit
Evaluate:
