INTRODUCTION

A Portfolio will be prepared on the management of Civil-Project. Aspects such as the Health & Safety, Environment management, Quality management, Financial & commercial management and Human Resource management will be explained in details. A case study will be taken up to provide sound support to the aspects mentioned above. The said case study chosen for the purpose is the famous Channel Tunnel.

The channel tunnel is the largest engineering project to be privately financed till date. The channel connects Folkenstein, Kent, United Kingdom to Coquelles, Pas-de-Calais, France covering 32 miles approximately. The project cost was around $14.7 billion or £8 Billion according to the Bechtel Corporation, one of the companies hired by the Eurotunnel to complete the tunnel as they faced completion problems after the inception of the project. This channel has three tunnels which are interconnected, while two on the either sides are used for the rail systems, the one in the centre is used for maintenance, passenger evacuation and fresh air supply. The project faced many problems such as financial problems, technical woes, schedules which were never fulfilled and public battles between Eurotunnel and its contractors. In spite of all this the project was completed in 1994, after it was initially thought of as early as 1802.

HEALTH, SAFETY AND ENVIRONMENT MANAGEMENT

For a business firm to sustain itself in the field of civil project development, it is utmost important for it to have an impeccable record in Health, Safety and Environment commitment and policies. It is so because, it affects contractors, its employees, its reputation and hence its stakeholders. Health, Safety and Environment (HSE) Management may cover these broad fields:

Safety coordination during various phases such as design, fabrication and construction

Preventive measures recommendation

Chalking out of coordination plans

Risk analysis with regard to safety of employees/workers

Deployment of health and safety plans

Access controls for designated areas

Control of personnel protection equipment (helmets, gloves, shoes, etc.)

Safety signaling control

Periodic auditing and special reporting about the non-conformities in the system

Training for management, supervisory and execution personnel of subcontractors and visitors

Conforming to the Environmental and legislative regulations

Safe transportation of Hazardous material

As the Table 1 illustrates, the construction sector shows very high rate of injuries /illnesses and hence lost workdays than in virtually any other industry. These injuries and illnesses prove to be exceedingly costly in times of rigid schedule. As quoting from Engineering Statistics, (Bowker & Liebermann, 1972)

"The Construction Industry Cost Effectiveness Project estimated that accidents cost $8.9 billion or nearly seven percent of the $137 billion (in 1979 dollars) spent annually for industrial, utility and commercial construction in the United States."

This includes direct costs (medical, workers' compensation premiums & benefits, liability losses & property losses) as well as indirect costs (like reduced worker efficiency and productivity, project delays and equipment damage). In such scenarios, innocent bystanders may also get. Hence such incidents have to be kept under check. Table 2 provides information about various incidents which might happen at a construction site. It provides basic information about how the precautionary measures must be directed for a civil project as keeping the workers well informed and providing them with good safety equipment will reduce more than half of these accidents. E.g. Harnesses must be given when risk of falling is there.

Case Study

Leadership: An emphasis was placed on developing skills among supervisors to encourage them to challenge unsafe practices and to actively encourage the workers to get involved in various health and safety programs.

Safety Briefing Workshops: Such workshops were attended from directors to workers so as to develop good co-ordination and communication among the workforce. These included safety inductions, presentations, and briefing sessions, site tours to give all sorts of information required by the workers to work effectively and safely.

Figure 2: Such a briefing workshop is going on regarding crane at site

Communication: programs such as Safety Task Analysis Risk Reduction Talk (STARRT) which was a pre-task briefing which enabled workers to converse with their supervisors regarding safety issues related to the day's work and the associated control measures. And The Target Zero Truck which was suggested by the workers it visits different sites with updates on safety and health issues. It was equipped to handle video conferencing to enable the workers to get in touch with their supervisors. Target Zero was taken up so as to make avoid any loss of worker's life.

Rewards and Reports: Updates and alerts were swiftly provided. Near miss incident were made easier to report with lesser paper work and rewards were provided for safe working practices.

Respect the Environment: this was the motto of this project. No marine life was disturbed in the process as it was underground project. Chalk extracted from excavation sites were disposed off in friendly manner in Shakespeare Cliff, UK.

Eurotunnel setup an Environmental Management System (EMS) to continually monitor the environmental performance and controlling impact of its operations. This was done by optimizing the management of waste (customers also included), of water and optimizing the power consumption. Eurotunnel has also supported the local environment by keeping noises /nuisances under check as far as possible.

The EMS system is based on the requirements of ISO 14001, which is a recognized standard for the setting up of environmental management systems. Eurotunnel for it efforts has been acknowledged numerous times including featuring in FTSE4Good Index, the ethical stock market index.

In spite of this 10 workers lost their lives during this project. (8 British and 2 French). While one died after being caught between huge concrete lining segment and the tunnel boundary wall. 3 others were killed by the trains carrying back-forth construction material.

QUALITY MANAGEMENT

Decisions taken during planning and designing stage regarding the standards to be maintained during the project's life-cycle can be described as the Quality of that project. These decisions can be according to the initial requirements/ demands, social & political laws and cost limits. Hence Quality control refers to the conformance to these set of standards. Quality management can be taken as sum of Technical, Operational and Project related aspect management. These are managed by a Quality Management System (QMS) which must adhere to some set standard like ISO 9001:2000. Quality assurance (QA) certification is provided for the QMS system by Government agencies to assure the investors of the organization's claims.

Technical Management

The technical aspect of quality management can be defined as conforming to the rules/standards set in the contracts. These contracts provide the general skeleton on how to run the project and hence can be described as its technical side. Activities and knowledge pertaining to an activity should not be confused here as it will be considered under the operations management.

Contracts, though often changed to reach a mutual agreement carry certain common features and use fixed industry standards such as the ones drawn by UK Institution of Civil Engineers (ICE) or International Federation of Consulting Engineers (FIDIC). These contracts have different structure and content based on different scope and type of project. These will include specifications, directions and instructions to employer, tenderers, employee and contractor. Bill of quantities along with schedule of work may also be present here but these can be modified. However, a defect correction period and a performance bond are present to keep the employers interests safe. Auditing is carried out from time to time and any violations or straying from the contracts is dealt harshly.

Project Management

Almost all big projects have problems related to this aspect of their quality management. These are generally encountered with delays, cost escalations and recriminations. And this so happens because the project is vaguely conceptualized or the full implications of it are not realized in this crucial phase. This might not work in the favor of the organization in most of cases hence, must be dealt correctly and carefully.

Figure 4: Graph showing escalating cost of rectifying work at each stage

As the figure shows it is much easier and less expensive to take things into account and make changes in the design stages as costs spirals out during the later stages. The reasons which might lead to a sudden need for rectification are lack of adequate of field research, poor planning, incomplete specification and inadequate training. Hence, in order to successfully manage and complete a project within the stipulated time following steps can be taken:

Right person must be chosen for the right job i.e. workers must be skilled; managers must have leadership, motivating skills etc.

They must share a sense of responsibility towards the work assigned to them.

The duties and responsibilities must be clearly and formally defined so as to avoid confusion.

Requirements must be well understood. Studies and research must be carried out appropriately to determine any unforeseen implication of any change.

Based on the requirement and research, a design blueprint must be prepared.

Planning must be done and feedback must be taken to keep the project running smoothly. Activities which are planned must be coordinated and monitored as part of the feedback system to make sure objectives are met.

Communication and coordination among different working and managing groups is essential.

Following these steps the management of the project is simpler and tends to give fruitful results.

Operations Management

After the initial contracts have been drawn and planning has taken place, the work needs to be started. Operations such as leveling of the site, plane surveying, setting out of tunnels, pipelines vertical support systems should be done. Testing pits for the soil should be made for testing Rotary core drilling, light cable percussion drilling and heavy percussion drilling. As the construction is to be carried out safely, it is necessary to test the soil by moisture contest testing, in-situ density testing and compaction tests. The equipment must be checked to avoid any mishaps during the operations.

To run the operations smoothly, the roles of employer and the managing engineer are very important. Following steps are important from operations 'perspective:

Any contract related ambiguity should be worked out as they set the guidelines.

Any design specifications required during the construction process.

Taking decisions on any unforeseen project scenario.

Maintaining an internal audit/check system to keep the progress according to the contract/specifications. Employer can keep a check on this process by having his own people inspect the progress and audit system.

Working out any planning process, certifying completion of some activity and keeping records of any claims made by workers, contractors etc.

Deciding on any coordination disputes or communication lapse.

These are generally along with financial power are segregated to keep the work from becoming piled up and to prevent misuse of power.

Quality Management System & Quality Assurance

Quality Assurance (QA) can be described as an instrument for ensuring that the construction process takes place according to a Quality Management System (QMS). This means that the QA system defines the structure, duties and responsibilities for implementing a QMS. Hence, having a QA system in place provides satisfaction to the employers about the continuous striving for success and perfection by the organization.

Case Study

Considering that the initial idea was put around 1802, general consensus could only be reached around 1970-80s. The technicality of the issue was stuck on the issue of national security which was nothing more than a political scenario. After getting over this, it was decided to make such a big project as a privately funded project as the success of it was at question. With a consortium of private players mainly banks, a team was made which was later called Eurotunnel, which was given concessionary period of 55 years from 1987.

Project management was difficult due to the sheer size of the project. This is evident from the delays caused due differences created by the increasing need for more money. Demand for money increased from £2.3 billion in 1985 to a final amount of £8 billion around the conclusion of the project. The delay resulted in the project lasting for a decade while the initial estimate according to study around 1984 was around 4 and a half years. Design had to be changed as wet regions were found around the UK coast and need cement and concrete injection which also raised the demand for funds.

Operations were marred by lack of communication and safety issues were also forgotten. But overall the project was completed successfully and is one of its kind.

FINANCIAL MANAGEMENT

A project starts with cost estimation taking into account capital cost, operation cost and the maintenance cost. Capital cost covers land acquisition, planning and feasibility studies, design both engineering and architectural, material, equipment, labor costs, insurance and taxes, inspection and testing and office overhead charges. Whereas the operating costs would cover staff wages, repair costs, renovation and other utility costs.

Important Features

From management point of view things to look out for are:

Land acquisition costs are the largest among this section and hence must be well thought out.

It is also important to consider any alternative facility or operation in place of a proposed operation if the possibility of reducing overheads is present.

Certain amount must be allocated for some contingencies, this facilitates better situation handling.

Future planning is important and any estimate should be done with an eye on project's future scope.

Cost indices must be taken into consideration in case the project is of a long duration. As it is evident from the figure that the costs will rise over the years.

Figure 5: Price and cost indices for construction for a US based Construction Company

Estimates should be based on production function which is a relationship between construction's volume and capital/ labor. It could also be based on unit cost of quantities or based on some statistical techniques.

A plan should also be made about how this estimated amount is to be allocated during the scope of the project from one phase to another. It would be more reliable if the allocation process is based on value of work completed which can be described as the product of certain units being completed and the billable labor hours spent per unit. Then, at any stage the amount of work completed in percentage is the ratio of completed value of work to that of the entire project. It thus becomes easier to track the expenditure and trap the loop holes within it. Curve B shows the effect of rapid capital mobilization while curve A shows slow mobilization.

Figure 6: Value of Work Completed over Project Time

A civil project has some facilities related to it and these can be economically evaluated and financed according to the needs. Such projects have some risks associated with them such act of god, suspension of work etc and hence must be financially covered in contracts.

Once the project enters into execution phase, record keeping and feedback become important for keeping control on the project and thus controlling cost expenses. Regular accounting and monitoring are important features of this.

Case Study

The initial cost in 1985 was quoted around 1431 million pounds. Operations such terminal and land surface works were bundled together while fixed equipment cost were kept separate. Service tunnel, running tunnels, lining of tunnel along with excavation phases were separately evaluated. While the costs of shuttle and locomotives procurement were kept separate. Details have been explained in the figure below.

Figure 7: The Construction contract in 1985

In 1987, according to the Building research establishment surveyed the quality problems on Britain's construction sites. They found that half of the faults were design related, and 40% of the problems arose from faulty construction. 10% was product failing.

Design faults

misunderstanding the client's brief to develop the design

using information which is incorrect or out of date

misunderstanding of the client's expectations of quality standards

lack of co-ordination between the designers.

Loose or inappropriate specifications

Construction faults

Not building to drawings or specifications

poor supervision leading to bad workmanship

insufficient management of the quality of construction.

In order to eliminate those potential problems many clients have looked to quality assurance to reassure them that they will get the right building without undue quality problems.
