COUNCIL POLICY 1. Council approved the south shore of False Creek as a let-go industrial area in July 1990, and made provision for the relocation of the land based operations from the Cambie Yard through the purchase of the former Burlington Northern Rail (BNR) Yards in the East False Creek Flats in 1992. 2. Council, in 1979, made provision for the future relocation of the water-based aggregate operation and related asphalt plant in Cambie Yard by securing the former Sterling Shipyard property on Burrard Inlet. 3. On July 26, 1995, Council approved the relocation of the Fire Training Facility from the Main Street site to the BNR yard, and put a hold on the property at the south foot of Main Street until Engineering Services reported back on its future Yards plan. PURPOSE This report reviews a proposal for relocating City aggregate and asphalt plant operations and recommends that a new aggregate and asphalt facility, with expanded recycling capabilities, be developed on a site on the Fraser River in order to realize major financial, technical and operational gains for the City, in the short and long- term. SUMMARY The Cambie Yard in False Creek will be planned and redeveloped to non-industrial uses over the next few years. The current land-based Yard Operations will be relocated, most likely to the proposed Yard at the former BNR site, pending the results of a major yard study which is expected by mid-1996. The water-based operations also require relocation and this report proposes a relocation and development process and a financing strategy. A detailed study of the aggregate handling and asphalt plant operation, identified major savings to the City by continuing existing operations. Without a City-run operation, prices would be subject to market forces and costs would increase. The study also identified additional savings to be made by adding a construction material recycling facility to the aggregate and asphalt plant operation. The costs for the relocation to the Fraser River are estimated at $13.3 million for Yard development and $5.0 to $6.0 million for land. The site at Main Street is owned in the PEF, and arrangements can be made to secure it for yard use. It remains possible that an alternative site might be located and final details on a preferred site will be reported back in early 1996. BACKGROUND The proposed redevelopment on the South Shore of False Creek will require the City's Cambie Works Yard to relocate. Property was purchased in the former BNR Yard, to accommodate the land-based yard operations. A site at the former Sterling Shipyard is being held for the water-based aggregate and asphalt operation, but further review identified potential community and site concerns as reasons not to locate there. An alternate City-owned site on the Fraser River at Main Street is available. Council recently approved the relocation of the Fire Department's Training operation from the Main Street site and put a hold on that site, subject to a report back on City yard requirements. The aggregate handling and asphalt plant operations are very important components of the City's Capital and Maintenance Programs for infrastructure. They provide an efficient (both in time and dollars) materials supply and production facility dedicated to serving Sewers, Waterworks, and Streets Operations. The estimated 400,000 tonnes of aggregate handled at the Yard each year are purchased through a public tender process and costs are low because of the high volume. Most of the aggregate materials are distributed to work sites in a combination of City trucks and privately owned hired trucks. Approximately 25% of the aggregate is used to produce asphaltic concrete (asphalt) products for street construction and repair. Currently, the aggregate and asphalt plant operation employs three full time staff and contributes to major savings in excess of $1.4 million per year, over contracted aggregate delivery and private asphalt supply. The aggregate operation works well, but can be improved with new handling equipment. The asphalt plant, installed in 1967 with an expected life of 25 years, has served the City well, but is experiencing increased maintenance costs and cannot meet the peak volume demands of the paving operation. With the timing of development of False Creek, the condition of the existing plant, and the need to be even more competitive, a comprehensive review of the City's aggregate and asphalt operations was done. The following discussion reviews current and future demands for aggregate and asphalt, compares current practice to other options for supply and production, and recommends continuing operations in a new facility on the Fraser River. DISCUSSION A detailed study was done of the current and future aggregate and asphaltic concrete needs of the City and how best to provide them. The complete study is available from the General Manager of Engineering Services and has been reviewed by Corporate Services, who agree with the study conclusions. The study answered the following questions: (a) how do City operations compare to other aggregate suppliers, asphalt suppliers and production options? (b) how will City operations handle, and what changes are necessary to meet, future demands? (c) what other ideas could be implemented to reduce costs and improve the efficiency of the operations? The following sections summarize the study findings. Aggregate Handling Currently, because of the large demand for aggregate materials generated by City operations, approximately 400,000 tonnes of aggregate are purchased annually by the City through a public tender process. The aggregate is delivered by barge to Cambie Yard, where it is off-loaded and made available for pick up to all City operations, including Parks and Recreation. Distribution from the central facility is by trucks dispatched by the user branches. The aggregate operation employs one equipment operator and one half of a foreman. In the existing facility, trucks are required to off- load some barges because there is insufficient handling equipment. Barge deliveries are coordinated by Materials Branch staff, as required. The low overhead and no profit requirement, make this operation very competitive. Numerous reviews have been done over the years that clearly indicate the costs for aggregate materials and delivery are lower with a City operation, than by private contract. An analysis of City versus private aggregate supply and delivery to job sites, identified savings (estimated at $750,000 annually) with the City operation. The current volumes of material used in City operations will continue into the future, given the requirements for infrastructure construction and maintenance. The overall operation is efficient, but could be improved. A new Fraser River Yard to replace Cambie Yard, offers an opportunity to install new material handling equipment and improve efficiency. Recycling of concrete rubble is proposed to reduce dependency on new aggregate materials and this option is discussed under Recycling. Asphalt Production The City produces approximately 100,000 tonnes of asphalt each year in the existing plant. The Streets Operations Branch uses the majority of the asphalt produced for new construction and maintenance, and repair of streets. The plant employs one equipment operator and one half of a foreman. As with aggregate supply, the City is competitive in its asphalt operation due to the low labour and equipment costs and the non-profit operation. In addition to the benefits of low cost, there are benefits from the plant location which give flexibility and quick response to demand. The current costs to produce asphalt were compared with other municipalities and private contractors. The lowest cost asphalt in the region was in Matsqui (now Abbotsford), where the price is $35.60 per tonne, compared with our price of $28.86 per tonne at a new facility. This conservatively translates to an annual saving of $675,000 per year over private supply. However, local prices are higher, in the range of $45.00 per tonne, suggesting real savings over $1.5 million annually. The analysis showed that the existing operation is extremely competitive and that replacement of the plant and addition of improved storage facilities, can make it even more so. Reduced dependency on new aggregate through increased recycling of asphalt would further reduce costs. Recycling During reconstruction operations, large amounts of concrete and asphalt rubble are removed and disposed of at landfills. The existing Cambie Yard site was too small and incompatible with the adjacent residential uses, to allow comprehensive recycling of construction materials. With the proposed relocation to the Fraser River, a significant opportunity to re-use and recycle asphalt and concrete and carry out limited soil and rubble separation, is created. Waste asphalt can be reclaimed and added to new asphalt mixes to reduce production costs by at least an estimated $350,000 per year. Concrete rubble can be crushed into aggregate-sized particles to be used as road base and trench fill. This would reduce our requirement for aggregate materials, thereby saving the aggregate operation an estimated $260,000 per year. In addition, savings in operations, estimated at $560,000, could be realized through reduced trucking costs and dumping fees currently spent to dispose of rubble at landfills. The current tender award for mineral aggregate is recommending a recycled concrete product. A recycling operation re-uses materials, reduces space demand at the landfill, reduces truck traffic in the region and is environmentally sound business. The savings identified above, are based on a thorough economic analysis. In carrying out the comparative review with private operations, market land lease rates were used to ensure that all costs were accounted for. The Analysis Report, available from the General Manager of Engineering Services, demonstrates that the continuation of City-run aggregate and asphalt production operations and the addition of a recycling capability, are in the best interest of the City from operational, environmental, and economic perspectives. PROPOSED NEW YARD Cambie Yard will soon be discontinued. The existing aggregate handling and asphalt plant operations described above are efficient, cost effective and provide best value to the City. For these reasons, it is proposed that the City develop a new Work Yard on the Fraser River to replace the water-based aggregate and asphalt plant operations from Cambie Yard. A proposed Fraser River Yard would accommodate the new asphalt plant and associated storage facilities, improved aggregate handling and a new recycling operation. A modernized materials testing laboratory would also be accommodated. The preliminary design would identify the site layout and geotechnical conditions, and refine the cost estimates. It is recommended that consultants be selected and hired at an estimated cost of $150,000 to carry out the design. FUNDING The conceptual estimate of the Capital Costs (excluding land) to develop the new Aggregate and Asphalt Facility on either site is: Asphalt plant $5,000,000 Aggregate handling 6,000,000 Recycling 2,100,000 TOTAL $13,300,000 It is suggested that funding could be provided from the Asphalt Plant Equipment Reserve (current balance $3,200,000) and potentially a loan from the Solid Waste Fund or some other element of private funding. An updated cost estimate and financing plan will be reported back after preliminary design is completed. The Main Street site is owned in the PEF and could be available for between $5.5 million to $6.5 million. The General Manager of Engineering Services recommends that the Sterling Shipyard and Commissioner Yard be marketed and that any shortfall in the land purchase price be funded through a loan from the Solid Waste Fund, to be repaid from the Asphalt Plant and Aggregate operation. Commissioner Yard would continue to operate at its current location, until it is relocated to the proposed new yard at the BNR site. CONCLUSION The existing asphalt and aggregate operations have served the City well for many years by providing necessary products at a lower cost than from other sources. With the pending closure of the Cambie Yard, and with the value to the City that the aggregate handling and asphalt plant provide, it is now appropriate to redevelop the facilities at a site on the Fraser River. The estimated total savings in operating and capital budgets with the new asphalt plant and asphalt recycling operation, will be over $1.0 million annually ($675,000 currently), when compared to outside purchase of asphalt. The estimated savings in the aggregate and aggregate recycling operation will increase from the current estimate of $750,000 annually, to over $1.5 million annually. The recommendations contained in this report will allow design and estimates to proceed, with a report back in Spring 1996. The target date for completion and start up is summer 1997. * * * * *
