1. Executive Summary:

This report revises the unit costs assumed, seeks to include fencing and survey related costs in relation to creation of easements and expands the scope of ‘The Lockhart Shire Council Sewerage Reticulation Feasibility Report South Side of the Olympic Hwy The Rock NSW’ that was presented to the Lockhart Shire Council in May 2014. Following the revision the over construction cost is estimated to be $6,058,000

2. Report Summary:

This report supplements the ‘The Lockhart Shire Council Sewerage Reticulation Feasibility Report South Side of the Olympic Hwy The Rock NSW’ as presented to the Lockhart Shire Council May 2014. Revision of the above mentioned report including: (Proposed layout see Appendix A).

Quantities of materials and works. Unit rate used within the report to determine costs. Clarification of assumed engineering design and project management cost. Pump Station supply and installation costs.

Expand the original feasibility study to include:

Provision for rock excavation. Provision for tree removal. Expand and itemise under boring cost for sewer gravity mains and sewer rising mains. Estimated cost for access to existing lots including fence removal, re-instate fencing

and landscaping. Cost to determine a feasibility allowance for necessary easement creation within

existing lots including any site survey costs and lodgment costs. Cost to determine a feasibility allowance for full feature and level survey for each

proposed catchment and existing infrastructure. 3. Report Cost Revision Gravity Sewer Reticulation:

3.1. Unit costs: Unit costs assumed within the report have been estimated from current projects

Esler and Associates are supervising within Albury and Wagga Wagga, an increase in cost factor has been added because of the relatively remote location of The Rock.

7.1. Engineering Design: A rate of 10% of the construction cost has been assumed for

engineering design of the project. 7.2. Engineering Project Management Cost: Costs associated with project management, project

supervision were excluded from the report, an allowance of 10% of construction cost will be included in the revised costs work as executed cost are assumed to be covered by this estimate.

7.3. Feature and Level Survey: Full Feature and Level survey for design purposes, estimated at $125.00 per potential Lot.

7.4. Easement Creation on Existing Lots: Estimated cost per lot for title plan, lodgment fee, Titles Office Fees, Solicitors and administration fees. Estimated at $1200.00 per lot.

8. Additional Project Costs:

8.1. Cost Excluded From the Original Report: Exclusions from the original Report were identified

and listed in part 3 of the report. 8.2. Lot Connections to Main: An allowance for sewer junctions for existing lots along the sewer

8.3. Access Tracks to Pump Stations: Estimated 600m2 Gravel track and hard stand around pump stations @$20.00 per m2 equates to $12,000 per pump station. Access track cost has added to the installation cost for each pump station.

8.4. Tree Removal: A $2,000 per tree removal cost has been added . It is assumed one tree every 100mtrs of sewer trench is to be removed, mulched and spread on landscape areas.

8.5. Rock Excavation Allowance: Rock excavation has been estimated at $230.00 per m3. For a 2mtr deep trench 600mm wide excavation equals 1.2m3, therefore use rock excavation is calculated at $276.00 per mtr of trench and assume 10% of trenching will be rock.

8.6. Spoil Removal: Remove of trench spoil from site to a stock pile nominated by council, assume $12.00 per m3. Volume of spoil is calculated at 0.36m3 per mtr of trench.

8.7. Site Establishment Allowance: An allowance of $20,000 per catchment has been included. 8.8. Location of Existing Services: Location using ground radar and/or nondestructive

excavation. Rate assumed to be @$175.00 per hour. Assume an average of 2 days per catchment area. Total allowance $36,000.00 equates to $2.95 per mtr sewer main.

Lockhart Shire Council requested all costs excluded from the original report be estimated and included in this report. A list and estimated value has been included on Section 9. Exclusion from the original report have now been included and the overall estimated cost for the sewer reticulation system has been revised to $6,058,000. To achieve a direct comparison with the DEUS report a second total cost of $5,080,000 excluding catchments 5, 9 and 13 has been estimated.
