1.0 Project Brief

KMCF are the Tendering Team working for a Small Civil Engineering contracting

organisation. Tendering Manager has requested to prepare a submission for senior

management documenting that the company approach to selecting a tender design for use

in a design and build works proposal which is Upgrade Works of Keadue Waste Water

Treatment Plant (WWTP) and project team is to develop a generic tender selection system

which is applicable to all future work for Keadue development.

In addition, the company are also requested to document how the KMCF Project Team

could handle the proposal, in the tender format provided, and develop a schedule and cost

performance system for use during the contract phase.

The KMCF team shall prepare the requisite quality and management systems necessary to

perform the following:

Responsibility Assignment Matrix A feasibility assessment system on two design options for the planned development

2.0 Background to Site

Keadue, Co. Roscommon has been chosen as the trial site for the incorporation of this

tendering and performance monitoring system.

The site is located close to Ballyfarnon 6 miles North of Boyle. It is on the location of the

existing treatment works for the village. The effluent flows by gravity through the existing

works.

The current treatment system existed on site is Traditional type system which can serve

approximately 300 PE and it consists of the following elements:

1 no. Split flow chamber and screens 1 no. Imhoff tank 1 no. Rotary Filter 1 no. Humus Tank 3 no. Sludge drying beds 1 no. Outlet inspection chamber 1 R d b d

2.1.1 Subsoil Database

Based on research conducted by National Soils Database which can be accessed in EPA

website, samples are taken approximately 0.48 km distance away from Keadue as shown in

Figure 1.

According to (Natural Heritage Area, 2005), any works will be constructed within this area

and the surrounding, must be specified for the purposes under section 19 (1) of the Act.

2.1.3 Other Relevant Maps

The following are relevant maps that also being considered in conjunction to the location of

the Keadue WWTP:

Aquifer Data (refer Appendix A) Bedrock - Structural Linework & Solid Geology (refer Appendix B) Bedrock - Generalised Map (refer Appendix C) Groundwater Well Data (refer Appendix D) Karst Features (refer Appendix E) Recharge Data (refer Appendix F) River Basin District Boundaries & Groundwater Bodies (refer Appendix G) Source Protection Area Data (refer Appendix H) Teagasc Subsoil Data (refer Appendix I)

Final comparisons consideration (Narrowed to the two best packages):

Ease of construction Economical use of land Time for completion Ecological footprint

Furthermore, this section also included alterations to compare different type of systems. For

instance larger systems could be compared for bigger sites.

4.0 Scheduling

Developed in a generic fashion to allow for the schedule to be altered for different sites or

the use of a conventional system.

4.1 Construction Schedule

Construction Scheduling is a process of breaking down a project into smaller activities and

the durations of time each will take, then organizing them into an order of actions to be

5.1 Earned Value Management

Earned Value Management (EVM) helps project managers to measure project performance.

It is a regular project management process used to find variances in projects based on the

comparison of worked performed and work planned.

EVM technique used to track the progress and status of the project and forecast the likely

future performance of the project. EVM integrates the scope, schedule and cost of the

project. EVM can be used to show past performance of the project, current performance of

the project and also show the future performance of the project. Good planning coupled

with effective use of the EVM technique will reduce a large amount of issues arising out of

schedule and cost overruns. Once the contractor's EVM System is considered and

implemented on a project, there are significant benefits to the contractors. Contractorbenefits make it easier to meet project schedule, cost and technical objectives.

The Contractors internal systems must be able to provide:

exists in accordance with Public Works Contractor for Civil Engineers Designed by Contractor

or if none exists by entering the delay.

5.2.2 Adjustment to contract sum

This is completed in accordance with Public Works Contractor for Civil Engineers Designed

by Contractor which can be completed by, taking existing prices off original Bill of Quantities

or altering existing prices in original Bill of Quantities or recalculating cost for the activity

taking into account, labour, materials, plant and design.

5.3 Automated Report Generator

The automated report generator is capable of updating automatically as the project

progress. As per the standard format of a Project Status Report, the document includes the

following:

Work planned for last month Work completed last week Work planned for next week O i
