A | EC | Environmental compliance requirements complete | 6/15/2013 | 6/16/2013 | Concluded | Joseph Connor (Inactive) | 4/4/2014 4:43:57 PM |
Description: On-the-ground work associated with this work element cannot proceed until this milestone is complete. Milestone is complete when final documentation is received from BPA environmental compliance staff (completion can be based on pre-existing environmental documentation from BPA). | |||||||
B | Suggested | Hold initial kick-off meeting with all stakeholders | 6/21/2013 | 7/12/2013 | Concluded | Joseph Connor (Inactive) | 4/4/2014 4:43:57 PM |
Description: Hold construction kick-off meeting with the contractors and CCNRD staff. | |||||||
C | Pile driving | 7/1/2013 | 7/31/2013 | Concluded | Joseph Connor (Inactive) | 4/4/2014 4:43:57 PM | |
Description: CCNRD will sub-contract to BNSF for pile driving and construction of a fish passable bridge under the BNSR railway prism. The proposed bridge will have an H-Pile foundation with 4 pilings at each pier for a total of 16 pilings. The pile foundations would be constructed using a railroad pile driver to allow for construction during track work windows and avoid the need for a shoofly track. Pile driving will occur from the top of the railroad prism. All piling installation work will be completed in dry conditions because they will be installed into the existing railroad prism before this is connected to Nason Creek and the floodplain. BNSF anticipates that 6 pilings can be installed per day. | |||||||
D | BNSF flaggers for construction safety | 6/24/2013 | 10/31/2013 | Concluded | Joseph Connor (Inactive) | 4/4/2014 4:43:57 PM | |
Description: CCNRD will sub-contract to BNSF for pile driving and construction of a fish passable bridge under the BNSR railway prism. The sub-contract will cover BNSF bridge installation, flaggers, and the costs of the easement associated with construction. More detailed information about the number, timing, and type of flaggers will be developed as part of the 60% design. | |||||||
E | Bridge Construction | 7/1/2013 | 10/15/2013 | Concluded | Joseph Connor (Inactive) | 4/4/2014 4:43:57 PM | |
Description: The proposed bridge will consist of an 89-foot three-span pre-cast concrete bridge placed in the existing BNSF rail embankment at BNSF MP 1690.58. This bridge would allow the removal of three existing 48-inch-diameter, 60-foot-long concrete pipes that are often plugged. This will provide a vastly improved hydraulic connection for both flood flow conveyance and fish migration between Nason Creek and the disconnected wetland floodplain and tributary stream habitats. The bridge structure would be constructed from the railroad. Equipment would include a pile driver to drive the piles for foundations; pile driving is more completely described under milestone 184 C. An excavator will be used to remove the upper portion of the railroad embankment to allow placement of the bridge components. Then, a crane will lift the precast concrete bridge deck pieces into place. Railroad vehicles will use the existing tracks to convey materials and equipment. Following bridge installation the area beneath the bridge would be excavated to allow Nason Creek waters to freely connect with waters currently impounded behind the rail prism and connected only through undersized culverts that are commonly blocked with debris. Earthwork actions under the bridge are described under work element 180. | |||||||
F | Construction easement | 6/24/2013 | 6/14/2014 | Concluded | Joseph Connor (Inactive) | 4/4/2014 4:43:57 PM | |
Description: In order to avoid a long term easement for the stream (just like a city would need if they put a road under a bridge), this bridge will be built under the construction easement. Then the construction easement will expire and everything will be turned back over to BNSF. The easement fees will be paid per sq. footage for the 34,000 sq. foot easement. | |||||||
G | DELIV | Bridge Installation | 8/30/2013 | Concluded | Joseph Connor (Inactive) | 4/4/2014 4:43:57 PM | |
Description: Installation of 4 H-pile pilings per pier for a total of 16 bridge pilings and installation of a bridge. The deliverable will include a construction completion report with photos to document bridge installation. |
