Transcription

1 August 17, 2017 Vancouver Fraser Port Authority 100 The Pointe, 999 Canada Place Vancouver, BC, Canada V6C 3T4 Attention: Jessica Mehigan Subject: Overview Kiewit Ledcor TMEP Partnership ( KLTP ) has been formed for the construction of the Trans Mountain Expansion Project (the Project ) in the Lower Mainland. KLTP has identified the 2115 Commissioner Street - Site 1 (the Site ) as a potential support site for the construction of the Westridge Marine Terminal expansion. The proposed scope of work for the Site includes; site preparation, construction laydown, security fencing, parking stalls, site offices, and temporary marine structures. This memo is intended to provide an overview of the scope of work associated with the western portion of the Site, designated as Site 1 and Waterlot 1 in Appendix A, in support of our application for a Category C permit, as described in the PER Application Guide. East Vancouver Port Lands The Site is located in the western end of the East Vancouver Port Lands (EVPL) region, within Area 1 as shown in Figure 8 of the EVPL Plan. Commissioner Street and a CP Rail ROW separate the site from the surrounding residential community. The East Vancouver Port Lands Area Plan was approved by the City of Vancouver, the Vancouver Fraser Port Authority (VFPA) and the Burrardview Community Association in 2007 to guide future development and Port operations. As part of the EVPL, the East Vancouver Port Lands Liaison Group was established comprising of representatives from Burrardview Community Association, City of Vancouver, CP Rail and the VFPA to advise on issues of mutual interest. KLTP comprehends the potential community impact of the project operations and will comply with the guidelines to minimize impact on noise, views, air quality of the area. We have reviewed the East Vancouver Port Lands Area Plan and anticipate the planned use for the site to be a mixture of Green - Marine Taxis, and Yellow - Works Yard, uses as defined in Appendix B of the Area Plan.

2 Green Uses Marine Taxis A moderate amount of marine transportation services will be required throughout the operation of the Site. A combination of large and small marine taxi will pick-up and drop-off employees on the Flexi-Float platform at the start and end of shift. A portion of the parking stalls will be allocated to the marine workers and each stall will be painted and numbered. Yellow Uses Works Yards The Site will be used for storage and assembly of construction materials and supplies throughout the duration of the Project. The majority of the lot space will be occupied with equipment and fabricated materials required to support the construction of the Project. An extensive list of equipment and materials can be found in the Operations section of this memo. Key Impacts KLTP recognizes the importance of the preserving the mountain and water views to the surrounding communities. As per the EVPL height guidelines, the proposed site falls under Area 1 with a recommended maximum height of 13.7 m (45 feet). The two mobile cranes on site will exceed the maximum allowable height for structures resulting in the potential obstruction of the views over the Port Lands of the Burrard Inlet and North Shore mountains. The Liebherr LR1300 crawler crane will have a maximum boom height of 240 feet (73.0 m). However, the width of the boom of the crane is approximately 2.5 m, much less than the limit considered in Policy H5 of the EVPL Plan. Likewise, the Tadano Rough Terrain GR-1000XL crane has a maximum boom height of 150 feet (45.7 m) and boom width of approximately 0.6m. The cranes will used in a variety of locations throughout the site and thus will not cause a permanent obstacle to the residents and public s panoramic views. The two proposed cranes will be used to load and offload large and heavy materials from trucks and barges, as this work cannot be safely completed with other material handling equipment such as forklifts. The cranes will also assist in the fabrication and assembly of materials and equipment within the Site. Description of Physical Works and Construction Activities In general, our intended purpose for this site is a marine off-loading facility and laydown yard for the project. In order to prepare the site for the intended use the following activities, as shown in Appendix A, will be undertaken on the property: - Minor clean-up and site grading including: o Removal of any debris left onsite o Filling in of pot holes

3 - Upgrades to existing ground, as required to support the mobile cranes. This may include: o Milling or removal of existing asphalt. o Temporary removal of the top mm of gravel. o Placement of Geotextile grid or fabric o Replacement, compaction and grading of gravel previously removed. o Import and placement of additional gravel required to achieve design capacity and grade. - Installation of 630 m of 1.8m high standard chain link fence, with barb wire above the top bar. - Installation of two 10m wide, double swing gate for vehicle and personnel access. - Placement of 55m of precast concrete barricades to delineate the Old Wharf. - Installation of a 300T crawler crane (Liebherr LR 1300 or equivalent) o Dimensions: 27 x 67 x 16.5 with max boom to tip height of Placement of a mobile rough terrain crane (Tadano GR1000XL or equivalent) o Dimensions: 47 x 11 x 12.5 with max boom tip height of Placement of mobile construction trailers and storage containers that will tie into existing power and communications. The laydown yard will consist of: o One Office Trailer 12 x 60 o One Lunch Room 10 x 40 o One Wash Car 12 x 32 o Two Mechanics Storage containers 10 x 20 o One Mechanics Office 10 x 20 o One Environmental Connex 10 x 20 o Four Storage Connexes 10 x 20 o One Dry Shack Heated Connex 10 x 20 o One 45 x 45 Covered Shop - Layout of approximately 50 parking stalls for onsite and offsite staff. - Construction of a Temporary Trestle consisting of: o A 30 x 115 Access Trestle o A 48 x 180 Main Trestle o 25 ea 600mm diameter pipe piles o 28 ea 900mm diameter pipe piles o 5 ea 900mm diameter dolphin piles o Structural Steel Superstructure o Timber Crane Mat working surface. o Bull rails, hand rails, etc. See Appendix D for the preliminary design of this trestle. Pipe piles will be installed as far as possible via vibratory method. Where necessary the installation will be finished using a diesel impact hammer. Underwater noise and pressure will be monitored and mitigated as detailed in the CEMP, provided in Appendix H-1. - Installation of temporary mobile small boat dock made up of three flexi-float barges.

4 o Dimensions: 10 x 100 flexi-float barge with a 77 x 4 engineered gangway. o Appendix E provides details of this barge and a conceptual design for the gangway. - Installation of ten temporary 1000W flood lights on the existing wooden poles along Commissioner Street. o These lights will be designed and installed based on the PER Guidelines for Lighting. o Specifically, they will be installed to improve safety and security on the site, without creating nuisance lighting for the neighbouring community or marine vessels. o Appendix F shows the detailed site lighting plan prepared by a qualified lighting professional. o We have confirmed the capacity exists within the network and will coordinate the light installation with BC Hydro. Necessary approvals and permits will be obtained prior to any installations. The center portion of the site, designated as the Old Wharf in Appendix A, will be barricaded and fenced off due to various structural deficiencies. Construction for site setup will begin after issuance of the Permit and will take 6-8 weeks to complete. The anticipated construction start day, if the permit review takes the full 120 days, is Monday, January 29 th, Table 1 below provides an approximate schedule for permitting, construction and operations based on accelerated and full-term review periods.

If any work is required outside of these hours, we will submit a Request for Amendment to Port of Vancouver. We understand that it may take up to 30 days for this amendment to be approved. During construction KLTP and its subcontractors will access the site to complete the aforementioned site preparations. We anticipate 1-2 contractors will be onsite each day, each having crews of up to 10 people, arriving in personal and/or company vehicles.

5 Marine contractors involved in the dock construction may also access the site via water. We currently anticipate the necessary pile for the trestle to arrive on barges and the structural steel to be delivered by truck. Further details on this will be provided as the design and planning progresses, prior to the issuance of this permit. Studies and Reports Final Structural and Geotechnical Design for the Trestle will be provided to VFPA for review and assessment prior to the issuance of this permit. These will be sealed by a Professional Engineer registered in the Province of BC. KLTP will also provide VFPA intermediary design drawings for review, as the design progresses. The design, construction and inspection of this structure will follow KLTP s policy for the Construction and Design of Temporary Structures and Construction Devices. The design and construction of any crane working surfaces will also follow the aforementioned policy. The final design and construction requirements of the trestle and crane working surfaces will be determined following a geotechnical site investigation. The Category A permit application for the completion of this investigation was recently approved and KLTP plans to complete the work in July and August, Appendix J is provided with this application as a preliminary assessment of the geotechnical site conditions and the work necessary to complete the geotechnical design for the site. The operational activity noise was considered and assessed in accordance to the PER guidelines. Upon completion of the project noise screening, the total weighted project score determined was A copy of the Project Noise Screening Worksheet can be found in Appendix I. A record of any noise complaints received by KLTP during construction or operations will be submitted to Port of Vancouver. Appendix K is provided as a Traffic Impact Study for the construction and operational use of the site. The study was prepared by a qualified Professional Traffic Engineer registered in British Columbia. Appendix H-1 through H-5 provide our Construction Environmental Management Plan (CEMP) and the following supporting documents: - Stormwater Pollution Prevention Plan - Spill Prevention and Emergency Response Plan - Terrestrial and Aquatic Bio-physical Survey Reports - Soil Management Plan (Part of the CEMP) As discussed in the Bio-physical Survey Reports, there is no planned tree or vegetation removal for this site. Prior to the issuance of this permit, KLTP will conduct the following studies in support of the application. - Site Utility Verification - Site topographical and legal surveys. o A preliminary site grading plan shown in Appendix G-1 Site Drainage Plan.

6 o A further detailed site grading plan will be initiated shortly and will be provided as part of Category C permit application in August, Review of any Environment Assessments provided by VFPA, include assessments conducted by the previous tenant. Additional studies and/or testing may be proposed pending KLTP s review of these documents. - The aforementioned geotechnical investigation Operations Once construction is complete, we will commence using the site for construction laydown and loading / offloading barges. Material expected to be handled and stored in the yard includes: steel pipe pile, steel sheet piles, steel beams, rebar, forms, lumber, beams, nuts and bolts, pipe modules, anchors, buoys, wire rope, skip boxes, piping spools, electrical components, and insulation. This storage and handling will continue until the completion of the Project, currently scheduled for December We anticipate approximately 50 vehicles will access the site each day during the operations period. These vehicles will mainly arrive at the site between 0600 hrs and 0700 hrs, and leave the site between 1530 hrs and 1800 hrs, Monday through Friday. The site will also be operational on Saturdays. We anticipate approximately 40 vehicles per day on Saturdays, arriving and leaving at similar times as during the work week. Buses will also be used to transport workers to sites throughout the project. This will require 1-2 buses, each making one trip at the start (~0630 hrs) and end (~1730 hrs) of each shift. Materials will be delivered to and hauled from site on road legal trucks. We anticipate up to 10 trucks per day will access the site. Appendix K is provided as a Traffic Impact Study. A 300T crawler crane and 100T rough terrain mobile crane will be stationed onsite to load / offload material from barges and road legal trucks in the laydown areas. Additional material handling equipment, such as forklifts and wheeled loaders will be onsite during the operational stage of the project. The equipment at Site 1 will consists of: - Liebherr LR T Crawler Crane - GR1000XL Tadano 100T RT Crane - Cat 966 Loader - 10 Ton Forklift - 20 Ton Fortlift - Welders - Air Compressors - Mechanics Truck - Portable Generators - Pile Driving Equipment (storage between season) - Company trucks

7 - Tractor Trucks with Trailer (to move pipe modules) - Man Lifts Marine Traffic We anticipate up to two barges being moored at site at any time and for barges to be brought to site, or hauled away from site approximately once per day. All barge moves will be controlled by tug boats with certified personnel. Appendix C shows our Marine Staging Plan. The anticipated draft of the barges and tug boats will vary between one and three meters. KLTP recently conducted a Bathymetric Survey of the area which confirmed that there is sufficient water depth to operate all our vessels as planned, regardless of the tide. Transit of Marine vessels will be conducted following the practices and procedures outlined in the Port Information Guide, particularly those regarding the MRA-2 area as the Second Narrows Railway Bridge is located between the 2115 Commissioner Street site and the Project site. This bridge provides 10.8m of vertical clearance at higher high water. We anticipate that the majority of our vessels will have an Air Draft of less than 8.8m, allowing for 2m of clearance under the structure. Communication of transits will be made with the Marine Communications and Traffic Services, per the MRA-2 Communications protocol. For vessels with an Air Draft of greater than 8.8m, marine transits may require special planning and consultation with BC Coast Pilots and Pacific Pilotage Authority. The water taxis will transport workers daily to the marine facility located approximately 5 km east of the Second Narrow s Bridge. This will require 2-3 water taxis, each making one trip at the start (~0630 hrs) and end (~1730 hrs) of each shift. One of these vessels will carry ~40 passengers and will measure 10.7m long x 4.8m wide. The other 1-2 vessels will carry 12 passengers and will measure 8.8m long x 3.4m wide. One of these water taxis will be on-call throughout the shift providing site access to supervisors, inspectors and other personnel. Aboriginal Consultation Consultation with Aboriginal groups has not been undertaken with regard to this site-specific project to date. KLTP understands VFPA will undertake an assessment to determine whether any of the proposed work could adversely impact asserted or established Aboriginal or treaty rights and to avoid, mitigate, or otherwise accommodate those impacts. KLTP will provide information requested by VFPA to inform its assessment as part of the application review. It is understood final determination of the legal duty to consult, scope of consultation, potential impacts to archaeological resources, participation funding and general timing will only be made upon review and consideration of a complete Project Application.

8 Public and Stakeholder Consultation The proposed project site is completely located within the jurisdiction of the VFPA. KLTP recognizes the longstanding and respectful relationship the VFPA has established with the communities adjacent to port lands; represented locally by the East Vancouver Port Lands (EVPL) Committee. KLTP has reviewed the EVPL Area Plan and acknowledges the efforts made by the community and the Port to balance the needs of residents and growing port trade. Consultation with the local community will be undertaken subject to guidance from the VFPA on their consultation requirements for this site-specific permit review. KLTP recognizes the proposed Project site was occupied by the original tenant for over 85 years. As such KLTP is respectful of local resident concerns to what changes of activity could be on site, including any changes to viewscape and marine activity to service the site. Consultation will help to refine project plans as the project undergoes project and environmental review; however, should the project be approved, ongoing communication with the community will remain an important element to supporting a collaborative working relationship between the VFPA and the community to address operational issues should they arise. End of Project At the end phase of the project, KLTP will remove all temporary structures, materials, and debris on site and perform a full site clean up to restore the premises back to its original state. Specifically KLTP will remove the trestle dock, flexi-floats, access ramps and any buildings brought onto site during the operations. Removals will follow similar means & methods to the early phase of construction. Closing We believe that we have provided sufficient information for you to review and accept our application as complete. Please do not hesitate to contact us if you have any questions or require any additional information. Sincerely, Kiewit Ledcor TMEP Partnership,
