This memorandum provides a project timeline summary and details of events that have affected the completion date of the Warner Milne Road project. The project experienced delays totaling ninety-eight (98) calendar days that were justifiable under the ODOT Standard Specifications.

• May 14, 2010 -Original completion date.
• September 21, 2009 -Onsite work began.
• September 21 – October 14, 2009 – During this time period the Contractor worked on the sanitary sewer improvements within the Danielson’s property and encountered a sewer manhole problem and a water line conflict which were not anticipated, thus leading to a justified contract extension. A contract change order was approved for the delays to the work. Nine (9) additional calendar days were provided to the Contractor.
•  November 4, 2009 – The Contractor broke a mis-located 2-inch galvanized water service at approximate station 26+75. A contract change order was approved providing one (1) additional calendar day and compensation for the Contractor’s work to repair the broken water service. This contract change order was included with the manhole replacements change order described above.
• January 18 -March 5, 2010 – During this approximately six week time period the project sanitary sewer improvements were put on hold to allow for relocation of a NW Natural Gas main. The gas main relocation was necessary due to the decision to replace an existing sanitary sewer manhole (manhole ‘A’) and the decision to replace the existing culvert crossing Warner Milne Road. Both these items were replaced as a result of unusual conditions encountered in the field that could not be anticipated. The existing gas main was installed too close to manhole ‘A’ for the Contractor to safely remove and replace the manhole. The gas main was also in direct conflict with the proposed culvert replacement. NW Natural relocated the gas main to the north using directional drilling methods. The gas main relocation work took longer than anticipated and the sanitary sewer improvements could not continue until the relocation work was completed. A draft contract change order providing sixteen (16) additional calendar days associated with the delay is currently being reviewed by ODOT.
• March 22 -April 23, 2010 – The Contractor spent this approximately five (5) week time period locating and repairing leaks in the newly installed water main. The project was delayed during this time period as the Contractor could not begin roadway reconstruction work until they successfully passed a pressure test on the new water main. No additional calendar days were added because the work was concurrent with other critical path work items. 
•  May 24 -June 16, 2010 – During this approximately three and a half (3.5) week time period the project area experienced record setting rainfall. Due to the heavy rains and high flow within the drainage ditch the Contractor was unable to complete replacement of the storm sewer culvert crossing Warner Milne Road. The culvert replacement was a critical path item as the roadway reconstruction could not begin until it was completed. A contract change order was approved providing the Contractor with twenty (20) additional calendar days. 
•  June 11, 2010 – The original plans called for reconditioning of Warner Milne Road west of the full depth reconstruction area. Reconditioning consisted of removal of the existing asphalt pavement, re-grading the existing aggregate base and placing new hot mix asphalt pavement. During trenching work for the sanitary and water system improvements it was determined that, given the nature of the subsoil and existing aggregate base, the pavement life would be increased substantially by full-depth reconstruction as opposed to reconditioning. The decision was made to perform a full depth reconstruction of the roadway. A contract change order was approved providing seventeen (17) additional calendar days to the Contractor.
• August 20, 2010 –
