Project Management

INTRODUCTION

Sound Project Management from concept to commissioning is the key to

success. When any project is taken up, each and every phase right from

inception till the final completion must be thoroughly, effectively andtightly controlled so that each successive milestone achieved in timecontributes to building the blocks of ultimate success in fulfillment of

desired objectives. Leading organizations in the world achieve success in

Project management by controlling the following four factors through all

phases of a project in order of priority.

1. Safety,

2. Quality,

3. Time and

4. Cost.

Basics of a Project:

1. Eco Friendly: Every project must incorporate requiredenvironment protection measures and meet the norms.

2. Competitive: The project must be competitive when comparedagainst similar projects being done by others in the field.

3. Project Cycle Time: With borrowed capital, reduction in projectcycle time goes a long way in reducing the project cost by way of

reduction in interest during construction.4. Efficiency in Operations: Basic design of the project must aim at

highest levels of efficiency in operations to fully justify time moneyand effort put in to build the project.

5. Quality and Safety: Without the high standards of quality andsafety in execution, no project can be successful.

6. Customer Expectations: Above all, ultimately, a project must beable to meet expectation of its Techno-economical viability.Projects must clearly establish this basic requirement.

7. Reliable Technology: Use of proven and reliable technology isessential for any project, to be called successful.

Trends, Issues and Critical Success Factors:

Following factors contribute to success of projects.

1. Clear Vision and Project Objectives: aims and objectives of theproject need to be clearly defined to set the right direction andtone to enable accurate assessment of benefits derived on projectcompletion.

2. Strategic and Detailed Project Planning: Detailed work

breakdown structure and integrated work plans need to be developed inthe beginning itself. Care is to be taken so that time estimation fordifferent activities remains as accurate as possible.

3. Dynamic Leadership: Similar to importance of the role of a good

captain in any game, role of dynamic leadership for a project isimportant. Positive, bold, timely and quality decisions taken by

them to steer a project towards success are very important factors.

4. Committed, Dedicated and Competent Team: Every projectrequires teamwork, close coordination and unidirectional efforts to

create a synergy. Along with hard work, required level of technicaland managerial competence in team members is essential.

5. Integrated Project Management Systems: Putting a sound

project management system, which is capable of integratingmultifarious, and multi agency activities being done in parallel is

required to ensure synchronism and converging of activitiestowards one common goal of project completion. This systemshould be able to organize, multi level planning and monitoring ofproject activities as per the requirement.

6. Project Cost Control: Effective built in measures to ensure

control of cost both in design and execution phases of a project areessential.

7. Owner's Involvement: Deep involvement of owner at every step

to see that above system functions to its full potential is must in

any project management. Elaborate systems and procedures alone

cannot guarantee any results unless they are effectively

implemented and every step is followed till its logical conclusion.8. Handling of Emergencies and Surprises: Mid course

corrections would be required to take care of any interim delays.

Applying what if logic to anticipate project surprises, assessment

of risks and putting in place a Risk Control and Mitigation

Plan is necessary. Adequate safety and fire protection measures

should also be a part of project execution.

Clarity in Contract Management: Large projects require handling of

major contracts. Following aspects are crucial to manage these

contracts. Optimization of contract packages for effective and fasterimplement-tation. Here, scope of entire project is coveredunder mutually exclusive packages.

Framing of qualification requirements to ensure competitionfrom competent agencies.

Broad based specifications to generate competition.

Clearly defined evaluation criteria and selection of agenciesbased on price and capability consideration.

Tie up of work programme and quality plans withcommitment of matching resources as part of contract.

Dispute resolution mechanism, introduction of incentives andpenalties.

Project Management

Mechanism for early closing of contracts after workcompletion.

Sound Engineering Practices: Major projects require a very strong

engineering support. Aspects related to engineering to be taken care

include

Up front engineering to maximum possible extent,

Standardization of plants and layouts,

Standardization of equipment,

Design automation,

Design simplification and reduction in number of components

and

High reliability of overall process, sub systems andcomponents.

Quality Assurance:

Control of quality from raw material stage.

Control of quality during manufacturing stages for major and

critical equipment with stage and final inspections at pre

determined check-points.

Quality assurance for field activities.

Strong Infrastructure Base: Many projects have been delayed due to

weak

infrastructure. It needs to be ensured that basic infrastructure of roads;

power, water, and tie up for raw material like steel and cement are made

before start of main construction for large projects. Project team and

team leader should be in position well in time. This will ensure

expeditious completion of the project.

Construction Technology: Choice of latest construction technology

helps both in safe execution as well as results in substantial saving interms of time. It also helps in improving quality of construction and

ultimately results in saving of costs. It is better if methodology to be

adopted for construction and erection is worked out, discussed and

decided in advance.

Resources: Inadequate resources spell certain delay for any project

execution. Adequate resources of men and material are essential in all

the phase of project like engineering, procurement and construction.

Manufacturing and Production: Detailed manufacturing plans,

advance tie up for raw material, timely engineering inputs, adequate in-

house facilities for manufacturing, outsourcing as per need are some of

the important factors that control timely supplies. Following can further

Project Management

help in this stage of project.

Timely procurement of bought out items,

Improved productivity through technology up gradation,

Dispatch of modular units in place of individual components,

Improved packing to minimize transit damages and Faster transportation tie ups.

Control and Monitoring: Close follow up and expediting at all levels

based on exception is essential in all the phases of the project. Every

team member must do it in his respective area with a sense of urgency

and ownership. Increased use of Information technology in this

area will help in faster work. Effective implementation of integrated

project management systems is essential for the desired output. Regular

audit and continuous improvement of these systems is essential for thedesired output and to keep pace with the changes.

Fund Management: Interruption in flow of adequate funds will

jeopardize the progress of any project. Performance linked budget

projections and their regular monitoring helps in better management.

Safety in Construction: During execution of any project, accidents of

any type will lead to delays, Danger or loss of human lives is to be

avoided at any cost. It can be checked with the following measures.

Built in safety clauses in contracts.

Adequacy of required skills in workers for that particular type

of job.

Availability of protective equipment.

Proper working conditions.

Adequate supervision.

Owners insistence for importance of safety.

Suitable incentives and penalties.

Smooth Transition to Normal Operation: A project is complete only

when it goes in normal operation phase and desired level of output in all

parameters is achieved on a sustained basis. Hence, momentum of first

start up of any project is required to be carried forward till this is

achieved.

Backward and Forward Integration: Completing a project in

isolation may not deliver results if it is a part of chain of projects. In suchcases, backward and forward integration to march the schedules of other

connected projects is essential to be constantly monitored.

Sources of Finance:

Owners Support:

1. Advance payment: The OWNER shall support the contractorby paying advance to cover contract front end expenditure suchas mobilization, early engineering work, and payments tosubcontractors, commission and insurances. Such advances willbe of the order of 10% to 20%.

2. Progressive payments: Payments for the supplies made anderection works shall be made within stipulated time withoutdelays to enable the contractor achieve progress to meet thetargets. The measurements of work, passing of the bills shall notbe delayed by the OWNER in the interest of smooth progress of

works.3. Retention amounts: The retention amounts kept by theOWNER from the progressive bills may be released to thecontractor as per the contractual terms without delay, as this willact as incentive for the contractor to finish the works.

4. Redemption of Bank Guarantees: The contractor will befurnishing the Bank guarantee for 5 to 10% value of the contracttowards proper performance of the contract. The contractor shallbe cautious while signing the guarantee and avoid wordingswhich enable the OWNER to get the BG redeemed on firstdemand without referring the contractor.

5. Documentation for payments: The documents to be

presented for payment shall be as simplified as possible to

avoid delays in release of payments due to misunderstanding.

Export Credits:

Export credit agencies are generally set up or sponsored by thegovernment with the primary function of encouraging the export ofmanufactured goods.

The criteria to be satisfied for obtaining support from export creditagencies:

Majority of equipment and services originate from theagency country,

Financial soundness and reputation of contractingorganization,

Financial soundness and reputation of OWNER organizationand

The category status (based on the GNP per capita inflation,stability etc.) of the Owners country.

Commercial Loans:



16/151

Project Management

These are often linked to export credits.

Development Aid:

In the case of developing countries Asian Development Bank, EuropeanDevelopment Bank, World Bank etc. provide Funding for the approved

projects to the utilities with certain conditions. The Bank may paydirectly to the contractor against documents.

It is important to see that the payments towards the supplies

made and the erection works completed are received from theOWNER promptly for meeting the expenditure incurred so that

the works will progress uninterrupted.

CRASHING ANALYSIS

Thus crashing involves crashing the critical activities.

Crashing of the project time may be required when the Transmission

Lines are ready to get benefits from the project early. It involvesadditional funds and men at appropriate time.

Time estimate in the Critical Path Method does not take into accountthe uncertainties or probabilities. The time estimates are single timeestimates and no range of time duration is considered. Considering theuncertainties the expected time for an activity can be worked out asbelow.

Expected Time (Te) = (T0+4 Tml+Tp) / 6

Where T0=Optimistic time

Tml=Most likely time

Tp=Pessimistic time

RECEIVING EQUIPMENT/MATERIALS AND STORAGE AT

SITE

The equipment and materials are generally transported to site by road

by lorries and tractor trailers. Special precautions are to be taken in

transporting heavy over dimensional consignments. Necessary prior

permits are to be taken from the road transport authorities fortransporting the following heavy and over dimensioned equipment.

Transformer tanks

Reactor tanks

Air- core reactors

400 kV bushings

Diesel generator set

Tanks for oil storage

Cooling equipment

Large welded structures etc

In case of galvanized steel structures, short simple members are

resistant to transit damage. Large welded structures are likely to bebent during transit, unloading. These can be straightened easily at site.A 100% bolted design is more resistant to transport damage than

welded designs or semi-bolted (ladder) designs.



24/151

Project Management

When transporting steel structures, these must be loaded in such away that white rust will not develop. This is best done by avoiding deck

loading and by using spacers to allow air circulation between the layers.

Unloading:

The following equipment is required at site for unloading the equipment/materials from the truck or tractor trailer.

Mobile crane

Fork lifters

Derrick crane

Slings, pulley blocks

The unloading and storage shall be supervised carefully to avoid damages.

Inspection on Arrival at Site and Insurance Claims:

The packing cases are inspected for transit damage. In case of anydamage, the matter is reported to the supplier and insurance company.

The insurance claim is lodged. The surveyors of the insurance company

conduct survey and assess the extent of the transit damage.

Transport damages should be attended within one week of arrival atsite. It is advisable to decide in advance which insurance inspection

authority one has to report to.

Insurance policies are taken by Project Management Group from head

quarters from experienced insurance company. For substation contractsAll Risk storage-cum-Erection Policy is preferred. It covers entire civil,

erection, commissioning work up to handing over to customer. All the

equipment, civil works are covered. Equipment insurance claims are

identified as

During Transport (Generally in separate transit policy)

During Storage

During Erection

During Commissioning

Damaged items should be segregated and kept for insurance survey.Packing case no., item no., date of arrival, transport truck no., details ofdamages should be noted and kept for surveyors. Photographs of

damaged packages should be taken.

Storage:

Three categories of stores are necessary for substation equipment:

Outdoor Fenced Store:

The outdoor storage area should be above maximum flood level, and

free from damp, mud etc. The approached road from the main road andto the substation should be firm and adequate. The necessary handlingequipment should be available.



25/151

Project Management

Indoor Closed Store:

Indoor storage building should have sufficiently large storage area andsufficiently large doors on road side and substation side. It should bewell ventilated and well lighted. There should be proper watch andward. Transformer oil brought in tankers should be stored in specially

built tanks. The oil drums should be stored as per recommendations ofthe supplier.

Storage room for instruments and special equipment should also beplanned.

Fire fighting arrangements must be adequate. Guidelines by insurance

company shall be followed.

INTERFACE BETWEEN CIVIL WORKS AND COORDINATIONBETWEEN VARIOUS ERECTION WORKS

The following activities have a close interaction between civil works and

erection works. Very close liaison between various groups is essential

from design to handing-over stages.

Foundation drawings

Cable trench drawings

Wall openings for air conditioning work

Piping through wall

Illumination work

Sound absorption techniques used
