Detailed Project Scope Statement

Project Objectives
To design, build, and commission the entire water supply infrastructure to supply water to 3,000 new homes in the Benburb Street housing development.
Project Boundaries
The project will be limited to providing water supplies to those houses and businesses within the new housing development at Benburb Street. Other new dwelling houses outside of this development are not included in the scope of this project. The project will not include any pipe work or fitting on the customer's side of the water meter. The project shall not include any development work at the water treatment plant.
Product Scope Description
The project will be carried out in three phases: design, construction, and commissioning. The design phase will include all activities required to specify in detail the features and characteristics of all pipe work, structures, buildings, and the plant required for the water supply infrastructure. This phase will include the site and geotechnical surveys of the proposed sites and routes and the ultimate selection of the appropriate route. It will also include the detailed specifications of all aspects of the water main itself, including fire hydrant placement and domestic hookups and meters. Detailed architectural, mechanical, and electrical designs for the pumping station and the elevated storage tank will also be created.
The construction phase will include all activities required to realize the designs created in the previous phase. It will include the acquisition of land, easements, and site permits. Construction will include the laying of 7,000 linear feet of six-inch water line, 26,800 linear feet of eight-inch water line, 3,500 linear feet of ten-inch water line, 15,300 linear feet of 12-inch water line, and the final domestic connection and meter installation. Fire hydrants will also be sited and connected. This phase will include the building and fitting out of the pumping station and will include both mechanical and electrical work necessary. Construction of the elevated storage tower will also be completed; the tower is a steel-reinforced concrete structure that will be built in stages. The overall water capacity of the tower will be 400,000 gallons.
The final phase of the project is commissioning, and this will include all activities required to provide drinking-quality water from the system to the end users. It will include activities necessary to pressure test and leak test the system. Flushing of the system will be carried out to remove any detritus left after construction, and finally, the system will be disinfected. Certification and test results will be provided upon handover of the project.
Project Requirements
The project will provide drinking water of a quality and standard that meets the National Primary Drinking Water regulations and the Safe Drinking Water Act at a supply pressure of 35 pounds per square inch and capable of supplying 1.5 gallons per minute. The project must be finished by December 31, 2005, and completed within a total budget of $15,000,000.
Project Deliverables
  • detailed infrastructure design
  • piping from water treatment facility at Northend to the housing development at Benburb
  • regulatory permits
  • restored excavations
  • pumping station
  • elevated storage tank
  • residential and commercial metering
  • fire hydrants
Product Acceptance Criteria
As a minimum, the specifications shall require acceptance testing to include pressure and leakage testing. Pressure tests shall be performed at a pressure of 50 percent above the working pressure at the test point and shall be maintained for two hours. The leakage test shall be conducted concurrently with the pressure test to check for excessive leakage. All water pipes shall be cleaned and disinfected.
Project Constraints
Several environmental constraints on the project arise due to the proposed routing of the pipe work and the site of the elevated storage tank.
Archaeology and Cultural Heritage
The area through which the pipeline is routed is rich in archaeological interests, including several Native American settlements and burial grounds. The final pipe work routing must seek to avoid these sites and thus avoid impacting them.
Ecology and Nature Conservation
The proposed elevated storage tank location is in an area of native vegetation, at an elevation above the area to be served. Given the potential for endangered species, this location presents potential environmental impacts that would not be present elsewhere. Project work will minimize the impact on the environment in this area and will comply with the Endangered Species Act where applicable.

Buried Utility Services
As the majority of the proposed pipe work routing is along the public highway, it will be necessary to avoid the buried services of other utilities, including electrical, gas, and sewerage services.
Project Assumptions
Granting of Permits
For the successful completion of the project, it is assumed that permits for site work and trenches will be granted to the project.

Availability of Materials and Plant
It is assumed that the required steel piping, construction materials, and plant and equipment for the project will be available when needed.

Availability of Labor
It is assumed that skilled construction workers will be available locally to work on the project.
Initial Project Organization
The following chart details the initial project organization.







Initial Defined Risks

The following risks have been identified that may impact the schedule, cost, or quality of the completed infrastructure:

  • incomplete design
  • inadequate site investigation
  • uncertainty over the source and availability of materials
  • appropriateness of specifications
  • availability of resources--particularly construction equipment, spare parts, fuel, and labor
  • uncertain productivity of resources
  • weather and seasonal implications
  • industrial relations problems
  • inflation
  • delays in payment
