What is project management?

Project management is the discipline of planning, organizing, motivating, and controlling resources to achieve specific goals. A project is a temporary endeavour with a defined beginning and end (usually time-constrained, and often constrained by funding or deliverables), (Chatfield, Carl) undertaken to meet unique goals and objectives, (Nokes, Sebastian 2007) typically to bring about beneficial change or added value. The temporary nature of projects stands in contrast with business as usual (or operations), (Paul C. Dinsmore 2005) which are repetitive, permanent, or semi-permanent functional activities to produce products or services. In practice, the management of these two systems is often quite different, and as such requires the development of distinct technical skills and management strategies.

The primary challenge of project management is to achieve all of the project goals (Lewis R. Ireland 2006) and objectives while honouring the preconceived constraints. (Joseph Phillips 2003)The primary constraints are scope, time, quality and budget. (PMI 2010)The secondary -and more ambitious- challenge is to optimize the allocation of necessary inputs and integrate them to meet pre-defined objectives.

The traditional approach

1. Project feasibility report

2. Planning and design

3. Execution and construction

4. Monitoring and controlling systems

5. Completion

1. Project feasibility report

Builders must show to the investors the project feasibility report before construction. Through the feasibility report investors will get the information he needed, such as the function of the project and he can get from the interests of the project. It is very important. It will determine the prospect of the project.

2. Planning and design

Through the feasibility report, investors agree to construction projects. The builders must submit the project plan and the project design. Through plan and design, the investors can realize more important information. How long can be finished the project? How much money will be cost in this project? What time can operation its function?

3. Execution and construction

Builder according to the plan and drawings hire professional personage to build.

4. Monitoring and controlling systems

The builders ensure the quality and schedule of the project in the construction process. Usually they will introduce some supervision mechanism to supervise the construction. The government will also have the supervision and inspection agencies project, ensure the normal construction project.

5. Completion

After a certain period of construction, the project finally complete consign is used.

Time

Cost

Quality

Time

It is a time limit for a project. This refers to the construction of the project need to how much time. In the same conditions, the longer the time limit for a project means the costs more. On the contrary, the shorter the time limit for a project cost means the less cost.

Cost

It is the project need to spend how many money. Cost and profit is all investors care most about. Due to the project construction period is long; there will be many changes during, so as to produce a lot of additional expense. How to reduce unnecessary spending is an important subject of builders. The investors may not unlimited increase investment.

Quality

Quality also is a very important factor. Investors do not want to invest in a project quality was very poor. The customers also don't want to buy poor quality goods. The builder also doesn't want to spend a lot on repairs.

The essence of the construction management is to search a balance between the three. Between the three are interdependent. If you want to shorten the construction period, will be to increase investment, will affect the quality. If you want to save cost, must affect time limit for a project and quality. If you want to have the perfect quality, will affect the construction period, will increase the cost.

Risk Management

Risk management methods are mainly control type risk management and financial risk management type two kinds of technology.

Control type risk management

Avoid risk.

Risk prevention.

Spread risk.

Control risk.

Financial risk management

Keep self-risk. It means enterprise assume risk of damage by itself. It can predict the short term enterprise can withstand the biggest loss. It is divided into active and passive keep reserved.

Transfer risk. It is to show enterprise in order to avoid losses, the risk transfer to other enterprise.

Project example

Introduced the project

We will have a project in the woodland AVE 4. We want to build a multifunctional building. It can use for factory; also it can use for warehouse. The project started in Jun 2011. The project completed in Jan 2012.

This building has 10 layers. The building floor height is 6m from the 1st floor to 8th floor. The 9th and 10th floor only can use for office. This project has two buildings (block1 and block 2). It also have a 8 floor ramp. The truck can from 1st floor to 8th floor.

This building is frame structure. Its column is concrete. Its main beam is tensioned beam.

Its slab is hollow core slab. The hollow core top is BRC. Its slab surface is 75mm THK concrete. Its staircase wall is concrete wall, but the staircase is per-cast staircase. Its roof is steel structure. Its leftmost has a public car park from 2nd floor to 8th floor. The lift located in the middle of the building. It has 2 transported people lifts and 1 cargo lift. Every building has an escape staircase from 1st floor to 10th floor. It is steel staircase.

We only do part of the concrete structure.

Work breakdown structure

This project we finished 5000 tons of rebar, more than 200,000 m2 formwork, casting more than 40,000 m3 concrete. We are installation more than 60,000m2 hollow core slabs. We are installation 58 per-cast staircases.

Manpower

Rebar worker: Workers will be divided into two parts. Part 1 does work in horizontal direction (tie in beam rebar, slab rebar). Part 2 does work in vertical direction (tie in wall rebar, column rebar). This distribution can improve workers skilled degree and tacit cooperation degree, in order to save manpower.

Carpenter: Worker also will be divided into two parts. It is same with rebar worker.

a Student's Work

Lady Using Tablet

This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

Examples of our work

Plaster: Demand less, we join the Bengali in the plaster. So reduce the wage expenditure.

Material

Our rebar will go outside making. We entrust a specialized iron processing factory production. So save processing machine rental and less rebar wastage. The column and wall rebar will in the backcourt processing, then use crane installation. The slab rebar will use BRC. It will save tie in rebar time. It also saves rebar.

We all use the system template. This will shorten the template installation and removal of time. The column template will use steel template. It wills saves the plywood and reduce the cost of the template.

We will use 18mm plywood, because it will saves the plywood change times. The 12mm plywood every use 3 times must change, but the 18mm plywood can use more than 5 times.

The engineer must strict calculation of concrete volume. Booking a moderate amount of concrete, prevent waste.

Mechanical

Due to the venue are bigger, rent three tower cranes. A lot of material needs to crane transportation. The column rebar, wall rebar and system template need crane to installation.

Installation construction elevator reduces the personnel and time. It can save workers time on the way. The workers have more time to working.

The project management is a comprehensive discipline. It from the last century developed so far. It constantly was absorbing other domain knowledge. Project management is a huge system now, so manage a project is not an easy thing.

I think to be a good project managers must have the following ability.

Ability to civil engineering technology primarily theoretical knowledge and practical skills.

Have the relevant management theory and method.

Have the relevant economic theory.

Understanding of the relevant laws and regulations.

Using the computer aided engineering management question ability.
