this is an simple investigation assignment using engineering judgment for area called "Meadowlands"
no reference required. just short answers u might need resource such as google map or Nearmap.
i have already done table "3.1" ,"3.2" so just answer the questions when is says "#2" for table "3.3" and "6.1"
make sure u keep ur response in green color. any question please let me know as soon as possible . and if you cant get it done please let me know now so i don't waste time . thanks
A small residential neighbourhood street sub-catchment identified in this document as Meadowlands is located in the north east of the suburb of Carindale and is shown in Figure 2.1 and has a developed area of 0.37km2. Each occupied allotment contains a single-family detached dwelling. Meadowlands is bounded to the south and east by Carindale Recreational Reserve, to the north by Meadowlands Road, and to the west by Baynes Street and Carindale Recreational Reserve. Figure 21 Meadowlands Residential Neighbourhood Sub-catchment in Carindale, Brisbane Complete the following Table 2.1 to determine the number of dwellings (i.e. driveways) on each street and the average number of vehicles per day generated by dwellings on each street (assuming a trip generation rate of 9.5veh/day-dwg). (In each cell, round to nearest: 1 dwg, 1 veh/day.) Table 2.1 Streets, their Dwellings and Classifications in Meadowlands Residential Neighbourhood Sub-catchment 3.0 Task B Environment Management The small residential neighbourhood street sub-catchment of Meadowlands in the north east of the suburb of Carindale from Task A above applies to this task. With your team having already determined the number of dwellings in Task A, complete the following Table 3.1 to determine the waste transfer task for Meadowlands assuming: one household per dwelling and an average household size of 3.2 persons/dwg, and the specific values provided in the table. For the bottom two rows, use your engineering judgment and online information available about waste management in Brisbane to identify destinations of collected waste (hint: locations of certain facilities include Acacia Ridge, Chandler, Rochedale, Rocklea). (In each cell, round to nearest: 1 svc, 1 kg/hh/yr, 1 kg/svc/yr, 0.1 kg/svc/clct, 0.01 t/clct, 0.01 load/clct.)

For Meadowlands, and based on the results of Table 3.1, use these proportionalities to determine the annual tonnages by waste type produced and their relative percentages.

Table 3.3 Waste Management Commentary for Meadowlands Residential Sub-catchment Question Sub-question Response 1. The greater north Carindale neighbourhood is bounded by Old Cleveland Rd, Creek Rd, Carina State School, Meadowlands Rd and Bulimba Creek and has a developed area of 1.04km2, all of which consists of residential development similar in type and density to the above sub-catchment. Discuss the whole neighbourhood’s needs with respect to vehicle loads per collection, by waste type by responding to these sub-questions. How many landfill (red bin waste) RCV loads per week (load/wk) does this neighbourhood produce? Provide comment. (# 2) 2. (# 2) 3. How many recyclables (yellow bin waste) RCV loads per fortnight (load/ftnt) does this neighbourhood produce? Provide comment. (# 2) 4. (# 2) 5. How many green bin waste RCV loads per fortnight (load/ftnt) does this neighbourhood produce? Provide comment. (# 2) 6. (# 2) 7. How many kerbside collection loads by type (light pickup/ trailer, medium rigid truck in respective columns) (pre COVID19) does this neighbourhood produce per annual collection event (load/yr)? Provide comment. (# 2) (# 2) 8. (# 2) 9. How many light pickup/trailer loads of householder transfer waste per week (load/wk) does this neighbourhood produce? Provide comment. (# 2) 10. (# 2) 11. Some of the red bin waste collected from the Meadowlands sub-catchment includes green waste, mainly from households that do not have a green bin. Identify from Table 3.2 for the Meadowlands sub-catchment, the proportion of overall household waste that ultimately goes to landfill. Assuming all other collection sources unchanged, by responding to the these sub-questions, identify how many additional green bin services would need to be taken up by households to reduce the sub-catchment's landfill waste by 2.7% of total household waste. What percentage of total household waste in this sub-catchment does landfill waste presently constitute? (# 2) 12. What is the objective percentage of total household waste in this sub-catchment to be constituted by landfill waste? (# 2) 13. What annual tonnage (t/yr) would therefore need to be shifted from landfill to composting? (# 2) 14. What would be the percentage increase in composting per year? (# 2) 15. How many additional green bin services would be required in the sub-catchment assuming each existing green bin household maintained their present use? (# 2) 16. Provide comment. (# 2) 17. Some of the red bin waste collected from the Meadowlands sub-catchment includes waste that could be eligible for resource recovery. Assuming all other collection sources unchanged, if a campaign resulted in each household placing 800g of such waste into the yellow bin instead of red bin each week, by responding to these sub-questions identify the changes in both landfill and resource recovery annual tonnage and proportions of each produced by the sub-catchment. What is the annual tonnage (t/yr) of sub-catchment waste that will change from landfill to resource recovery? (# 2) 18. What will be the change in landfill waste as a percentage of total waste? (# 2) 19. What will be the change in resource recovery waste as a percentage of total waste? (# 2) 20. Provide comment. (# 2) 21. Assuming that on top of the personal annual waste rates for red bin and yellow bin listed in Table 2.1, an additional 0.9% is spilt onto the street and not recovered in the collection process, by responding to these sub-questions determine how much additional waste this amounts to and where it would most likely end up. What is the combined annual tonnage (t/yr) of sub-catchment red bin and yellow bin waste that is collected? (# 2) 22. What is the additional combined annual tonnage (t/yr) of red bin and yellow bin waste that is spilt onto the street? (# 2) 23. What is the additional combined average weekly mass (kg/wk) of red bin and yellow bin waste that is spilt onto the street? (# 2) 24. Where would be the most likely location in the immediate area where this waste would end up? (# 2) 6.1 Task E Bridge Structure The Meadowlands Rd Bridge (MRB) is located in the northeast corner of the aerial photograph of the small residential neighbourhood street sub-catchment of Meadowlands shown in Figure 2.1. Photographs of the MRB are shown in Figures 6.1 to 6.6 below. The purpose of this task is to compare and contrast structural aspects of the MRB with those of the Goodwill Bridge (GB), which was covered in EGB123 class, by completing the “Response” column for the MRB in Table 6.1.
