Question 9

Briefly describe three important reasons why estimates are used in budgetary control?

Answer 9

A company may need to know in advance what a project will cost to budget for it to know whether undertaking the project will benefit the business and in what timescales

Cost, Benefit & Timescale

Question 10

Give one example of cost effective planning specific to an overhead network?

Answer 10

• Calculation of pull on pole to determine whether a stay is necessary.
• Pole siting and spacing to avoid additional poles or support techniques.
• Pole siting to reduce disruption, signing, and guarding and enable maintenance.
• Pole siting to enable the maximum number of houses to be served
• Correct sizing of aerial cables to meet forecast growth over the specific period as dictated by the strategic planning policy.
• Avoidance of private wayleaves.

Question 11

Give one example of cost effective planning specific to an internal network?

Answer 11

• Minimum tray size to meet initial demand with allowance for flux and reasonable growth.
• Shortest route lengths achievable.
• Sufficient outlets to meet the design specification.
• Minimal fleeting

Question 12

Give two specific uses for each of the following types of survey Preliminary?

Answer 12

• A preliminary survey is used generally as a feasibility study which may be used for:
• Assessing broad costs to enable a company to develop a business case for a project, this may be used to give a company an indication of costs for its strategic planning policy
• Costs for inclusion in an invitation to tender
• A customer to budget for a future project
• Identification of potential assured routes

Question 13

Give two specific uses for each of the following types of survey Detailed?

Answer 13

will provide sufficient information to determine the optimum route for construction and will identify all engineering and 3rd party issues, allow sufficiently accurate estimate of time, quantities and work disciplines to be produced from which costs and programming can be calculated

Question 14

Describe three ways in which third party issues can affect a project?

Answer 14

• Private Wayleaves will need negotiation between the relevant parties; frequently these parties now include legal representation. Failure to recognise a private wayleave issue will inevitably result in a delay to project completion.
• Additional funds are required for the legal representation of both parties, and the actual cost of the wayleave.
• A wayleave is not transferable in ownership and a new owner may wish to renegotiate the terms for more money.
• A private wayleave across land for instance may not be secure in so much that the owner may decide to develop the land and decide to terminate the wayleave agreement requiring that plant is removed
• A wayleave for placing plant etc within a building will require a detailed method statement to satisfy the building owner or his/her agents
• Frequently owners are only prepared to negotiate wayleaves for an initial cable installation and every subsequent installation is subject to additional negotiation and associated costs
• Parish councils like to know of any potential disruptions in their parish and they have very strong contacts with the Local Authority and dignitaries such as MPs. To ignore their presence may result in delay whilst enquiries are made by their contacts
• The new Roads and Street Works act 1991 requires that all works in the public highway are noticed and co-ordinated. Under this procedure previously noticed utility works could take priority over the project requiring deferment or route change
• The Local Authority’s resurfacing schedule may take priority over the project especially towards the end of that Authority’s financial year, requiring deferment or route change
• A public event may be scheduled which conflict with the project programme and the police could require deferment or route change
• The police and the Highway Authority will have an input into the negotiation of critical junctions, which will affect costs and timescales.

Question 15

Give three Acts of Parliament that need to be considered at the planning stage of an infrastructure project?

Answer 15

• The Communications Act 2003
• The Telecommunications Act 1984

Question 17

State how a planner interprets a Customers requirement in respect of an order from another company for additional services?

Answer 17

Many customers simply know what they would like to have, for example the number of outlets in a building, but not how to achieve the desired conclusion. It is the role of the planner to accurately translate a customer’s requirements whether internal or external, into an engineering scope of works that will meet the customer’s needs.

State how a planner interprets a Customers requirement in respect of a highway widening scheme?

Answer 18

In the case of a highway scheme the planner must be able to fully understand the drawings especially where changes in elevation may be involved and the impact upon existing apparatus
