Transcript of Construction Project Management

What is a Project?

A project is a Sequence of tasks Planned from beginning to end Bounded by time,
resources, & required results and within certain cost and other limitations.




Introduction

Project management is the application of knowledge, skills, tools, and techniques applied to project activities
in order to meet or exceed stakeholder needs and expectations from a project.



What is Project Management?

The major cause of project failure is not the specifics of what went wrong,
but rather the lack of procedures, methodology and standards for managing the project.

What can go wrong in a Project?

The Triple Constraint

Work breakdown structure
The work breakdown structure defines the product elements (work packages) and their interrelations to each other and to the product.

Project Management Cycle (PMC)

In a project network, a dependency is a link amongst a project's terminal elements.
There are four kinds of dependencies with respect to ordering terminal elements
(in order of decreasing frequency of use):
1. Finish to start (FS)
2.Finish to finish (FF)
3.Start to start (SS).
4. Start to finish (SF)

In our project we will discuss how to make a project management
for two buildings from the skeleton to the finishing which are :
1. King Abdullah II School for Information Technology (KASIT).
2. Misbah Plaza Office Building.

Our Project

King Abdullah II School for Information Technology (KASIT)

Part 1

KASIT was established in year 2000, with the directives of His Majesty King Abdullah II in the development of IT in Jordan.
Proceeding from the goals and aspirations of (KASIT) in the preparation of scientific cadres specializing in the field of IT; to supply the local and Arab market, the faculty has worked on providing programs and laboratories equipped to achieve its vision.

Overview about The College

Plastering
Plaster is a building material used for coating walls and ceilings. Plaster starts as a dry powder similar to mortar or cement and like those materials it is mixed with water to form a paste which liberates heat and then hardens. Unlike mortar and cement,
plaster remains quite soft after setting, and can be easily manipulated with metal tools or even sandpaper. These characteristics make plaster suitable for a finishing, rather than a load-bearing material.

Tiles work

A tile is a manufactured piece of hard-wearing material such as ceramic, stone, metal, or even glass.
Tiles are generally used for covering roofs, floors, walls, showers, or other objects. Tiles are most often made from porcelain, or ceramic with a hard glaze, but other materials are also commonly used, such as glass, metal, and stone.
Tiling stone is typically marble, granite or slate. Thinner tiles can be used on walls than on floors, which require thicker, more durable surfaces.

Painting work

Painting is the practice of applying paint,
color or other medium to a surface (support base).
Paintings may have for their support such surfaces as
walls, paper, wood, glass or concrete, and may
incorporate multiple other materials including sand, clay, paper.


Sample of calculation

All the length, width, & height are brought as dimensions from drawings.
The quantity includes the area of painting in all the walls after subtracting the windows and doors.
Area of painting in walls = height of wall * length of wall  
Length =15.10 m Width=9.45 m Height =3.00 m
Area of windows =2.00 m2 Area of door =2.80 m2 No. of Doors =2 No. of Windows=4


Painting Calculations

Side Area = (2*Length*Height) + (2*Width *Height)
Side Area= (2*15.10*3.00)+(2*9.45*3.00)= 147.3 m2
Side Painting= Side Area – (Area of windows * NO. of windows)-(Area of Doors *NO. of Doors)
Side Painting=147.3-(2*4)-(2.8*2)=133.7 m2
Ceiling Painting = Length *Width= 15.1 * 9.45= 142.7 m2
Doors Painting= Area Of Doors = 5.6 m2
Total Painting= Side Painting + Ceiling Painting + Doors Painting
Total Painting = 133.7+142.7+5.6=282 m2

All the length, width, & height are brought as dimensions from drawings.
The quantity includes the area of plastering in all the walls after subtracting the windows and doors.
Area of plastering in walls = height of wall * length of wall
Length =15.10 m Width=9.45 m Height =3.00 m Area of windows =2.00 m2
Area of door =2.80 m2 No. of Doors =2 No. of Windows=4
Plastering Calculation

Side Area = (2*Length*Height) + (2*Width *Height)
Side Area= (2*15.10*3.00)+(2*9.45*3.00)= 147.3 m2
Side Plastering = Side Area – (Area of windows * NO. of windows)-(Area of Doors *NO. of Doors)
Side Plastering =147.3-(2*4)-(2.8*2)=133.7 m2
Ceiling Plastering = Length *Width= 15.1 * 9.45= 142.7 m2
Total Plastering = Side Plastering + Ceiling Plastering
Total Plastering = 133.7+142.7=276.4 m2


Floor Tiling for Rooms
Length =15.10 m Width=9.45 m

Floor Tiling = Width * Length
Floor Tiling= 9.45 *15.1 =142.7 m2
Tiling Calculations

Bathrooms Tiling
We have use two different parts of tiles in bathrooms one for the floors and the other for the walls
For Example:
Length =9.25m Width=8m Height=3m Doors NO.=2 Doors Area=2.8
Side Tiles = (2*Length*Height) + (2*Width *Height)
Side Tiles=(2*9.25*3)+(2*8*3)=97.7m2
Floor Tiles= Width * Length
Floor Tiles=8*9.25=74m2


After calculating the quantities of painting ,plastering and tilling we have visit the college
and assess the current painting plastering and tilling for each floor and then we find the
score by applied this rule :
Assessment= rate *magnitude of quantity in each room
Score = sum of assessment /sum of quantity
Quantity : means either tiling, painting or plastering

Rate calculation

Score at ground floor for tilling =sum of assessment for tile /sum of quantity of tile
Score at ground floor for tilling= 4771.84/ 683.32= 6.98

This value means that the tiling is good and don’t need to be changed at this time. it can serve for more years from now.


Misbah Plaza Office Building

Part 2

Work breakdown structure

Demolition
Demolition is the tearing-down of buildings and other structures.
For small buildings, such as houses, that are only two or three stories high, demolition is a rather simple process.
The building is pulled down either manually or mechanically using large hydraulic equipment: cranes, excavators or bulldozers.
Larger buildings may require the use of a wrecking ball, a heavy weight on a cable that is swung by a crane into the side of the buildings.
In our project demolition takes 11 days
Casting concrete
A reinforced concrete column is a structural members designed to carry compressive loads,
composed of concrete with an embedded steel frame to provide reinforcement. For design purposes, the columns are separated into two categories: short columns and slender columns.


Casting concrete

A concrete slab is a common structural element of modern buildings. Horizontal slabs of steel reinforced concrete, typically between 100 and 500 millimeters thick, are most often used to construct floors and ceilings, while thinner slabs are also used for exterior paving.
In many domestic and industrial buildings a thick concrete slab, supported on foundations or directly on the subsoil, is used to construct the ground floor of a building.

Block Work
Block Work
A concrete masonry unit (CMU) – also called concrete block, cement block, and foundation block – is a large rectangular brick used in construction.
Concrete blocks are made from cast concrete, i.e. Portland cement and aggregate, usually sand and fine gravel for high-density blocks. Lower density blocks may use industrial wastes as an aggregate. Lightweight blocks can also be produced using aerated concrete.
Plastering
we have use 2 group of man labor for this task.
Plastering
Ceiling
A ceiling is an overhead interior surface that covers the upper limit of a room.
It is not generally considered a structural element, but a finished surface concealing the underside of the floor or roof structure above.
Ceilings are classified according to their appearance or construction.

For example:
Quantity of Block work is given in the following table for each type :


Activity Duration Determination

Activity Duration Determination

Productivity for 1 m2 = 1day / P
Productivity for 1 m2 @ 20cm block= 1/60=0.017
Productivity for 1 m2 @ 15cm block= 1/50=.020
Productivity for 1 m2 @ 10cm block= 1/44=0.025
Duration = Qty for each floor* Productivity/m2
Duration for 1 m2 @ 20cm block=40*0.017=7 day
Duration for 1 m2 @ 15cm block= 80*0.02=2 days
Duration for 1 m2 @ 10cm block=233* 0.025=6 days


Cost Estimation

In a world of limited funds, as a project manage you're constantly deciding how to get the most return for your investment.
The more accurate your estimate of project cost is, the better able you will be to manage your project’s budget. Therefore, estimating a project’s costs is important for several reasons:
It enables you to weigh anticipated benefits against anticipated costs to see whether the project makes sense.
It allows you to see whether the necessary funds are available to support the project.
It serves as a guideline to help ensure that you have sufficient funds to complete the project.


How to Estimate Project Costs

Although you may not develop and monitor detailed budgets for all your projects,
knowing how to work with project costs can make you a better project manager and increase your chances of project success.
Your project’s budget includes both direct and indirect costs.


Direct costs include the following:
Salaries for team members on your project
Specific materials, supplies, and equipment for your project
Travel to perform work on your project
Subcontracts that provide support exclusively to your project


Indirect costs fall into the following two categories:
Overhead costs: Costs for products and services for your project that are difficult to subdivide and allocate directly.
Examples include employee benefits, office space rent, general supplies, and the costs of furniture, fixtures, and equipment.
You need an office to work on your project activities, and office space costs money. your office space is treated as an indirect project cost.


General and administrative costs: Expenditures that keep your organization operational (if your organization doesn’t exist,
you can’t perform your project). Examples include salaries of your contracts department, finance department, and top management as well as fees for general accounting and legal services.

Microsoft Project is a project management software program, developed and sold by Microsoft,
which is designed to assist a project manager in developing a plan, assigning resources to tasks, tracking progress, managing the budget, and analyzing workloads.
Microsoft Project was the company's third Microsoft Windows-based application, and within a couple of years of its introduction it became the dominant PC-based project management software.
