Quality Assurance :
-It’s the system of actions and procedures to assure that the given products verify the set requirements.

Quality control :
-It’s the techniques and activities used for testing and inspection to examine and fulfill the stated requirements for quality.

People Responsible for Quality Plan:


Quality Manager.
Quality Assurance Engineer.
The Quality Control Engineer.
Technician .

Quality assurance

Back filling:
- The back filling will be from clean sand.
- Horizontal layers of 25 cm thickness
-Compaction to 95% of maximum dry density at the optimum moisture content.

Concrete Casting:
1. Pouring and compaction of concrete should be done in less 30 min after finishing mixing in normal conditions, and 20 min in hot conditions ( More than 30'C ).
2. Stop joints should be determined before starting concrete pouring.

Steel Structure works:
1-Align each part of the structure before making field connections.
2-Install high strength bolted joints.

Quality Control
Earth works:
Sand Cone Test:
- Determining Density of soil in place and moisture content.

1. Compressive strength of concrete:
-Test is performed in laboratory, on the samples taken during casting in the standard forms (Cubes).
Concrete Works:
2-Slump test
-Indicates if the concrete mix is wet or dry or in between and will define if it has the required workability or no.
Steel structures:
Steel Testing:
Using ultrasonic, magnetic particle, radiography, and visual inspection.
Resource Profiles

( Taxes, insurance, safety )
What-If Scenarios
Problem (1):
-Political Demonstrations.

Time Impact:
These demonstrations delayed project about a month during the construction phase

Cost analysis:
The contractor will not be responsible for any additional costs and will be granted a time extension.
While the employer will be responsible for one month's indirect cost which equals = 620,981 LE
Problem (2):
Quality Tests Failure:
The original duration of these activities was from (25-May) to ( 10-June) =15 days.
So if we double the crews of these activities it should be re-done in 8 days.
In addition to the removal time which will equal 10 days.
So the total repair duration will be = 18 days

Cost Analysis:
Assuming 7 workers 150 LE/day and we have 35 columns and productivity rate = 1 column / 2 days
The cost of removal of old columns (concrete only) for whole floor = (0.5*35*7*150)=18,375 LE
Cost of doubling the crews = 2*cost of columns activities - 2*cost of steel rebar - 1*cost of concrete = (2*627,888)-2*(4*94,500) -(4*39,200) = 342,976 LE
So the total cost of repair is = 342,976 + 18,375 = 361351 LE

Cash Flow & Over Draft
Cash out flow is the cumulative form of the costs incurred by the Contractor on the project on a monthly basis

Cost = Direct costs + Indirect costs

Direct cost

Indirect cost
Equal 8% from total budgeted cost
Monthly indirect cost = Indirect cost / Project duration

2-Cash inflow:
is the movement of money into or out of the project.

Importance of cash flow analysis:


Components of our analysis
1- Cash outflow
2- Cash inflow
3- Cash overdraft

Cash flow analysis



Retention percentage (R %)

The retention is a percentage of the project's price that is deducted from the Contract monthly to insure that the Contractor completes the construction and is returned to him after 12 months from the primary delivery time=10%
retention =0.1*contract price
Cash inflow is the series of payments from the Owner to the Contractor in response to the invoices issued by the later taking into account the following:
Addition of the markup (M %)
The markup is a percentage of the total budgeted cost that covers the contingency and the profit of the Contractor from the project = 8 %
Invoice price= Total Cost * (1 + M %)




1-Cash outflow:

Advance payment

is a percentage from the project's price. Its amount is given to him in the beginning of the project to facilitate the construction in the first few months when there is no payments from the Owner = 25%
Advance payment value = 0.15 * Project's price

Cash in= Invoice price – advanced payment-retention


Cash-in & Cash-out:
Overdraft
Cash over draft is the difference between the cash inflow and the cash outflow
Cash overdraft = Cash in – Cash out
there is a huge positive overdraft at the beginning of the project that can cover the negative overdraft if this money will not be used or invested elsewhere

Selected Topic 1
-It is a rating system for buildings that was designed to guide and distinguish high performance buildings that have less of an impact on the environment
-Rating systems are groups of requirements for projects that want to achieve LEED certification

(LEED) Leadership in Energy and Environmental Design
OUR HOSPITAL is a building design & construction.
There are five rating systems that address multiple project types:
-Typical certification thresholds
We try to achieve silver certificate for the project.
-Each rating system is made up of a combination of credit categories,The number of points the project earns determines the level of LEED Certification the project receives.

Selected Topic 2 & 3
Project Planning
Dupming Analysis

Tower Cranes Conceptual Planning

• At mobilization stage and before starting Earth works, two Tower Cranes shall be fixed to serve whole area.

• We will consider some options for the tower cranes locations.
And that is the option (3rd option) which was already chosen in the project.
MOBILIZATION CONCEPTUAL PLANNING:

Temporary offices, facilities and Clinic are built before the earth works and foundation works commence, to accommodate site engineers, then offices are moved to basement after basement concrete works are done.

Storage:
• Some storage places shall be moved to the basements after its construction.
• Storage of steel only will be on site, otherwise storage will be in an area behind the site and transportation of material will be through trucks.
• Steel bars preparation will be carried out in external workshop, then transported and stored on site.

• Pouring Concrete:
Pouring Concrete will be through pumps of arm 42 m.

Option (1)
Using 5 trucks:
Cycle time=17 min.
Utilization factor for loader 1=15/17=0.88=88%
Utilization factor for Truck 1 to 5=17/17=100%
Utilization factor for loader 2=10/17=0.588=58.8%

Option (2)
Option (3)
Using 6 trucks:
Cycle time=18min.
Utilization factor for loader 1=18/18=100%
Utilization factor for Truck 1 to 6=17/18=0.944=94.44%
Utilization factor for loader 2=12/18=0.666=66.6%

Using 7 trucks
Cycle time=21min.
Utilization factor for loader 1=21/21=100%
Utilization factor for Truck 1 to 7=17/21=0.809=81%
Utilization factor for loader 2=14/21=0.666=66.6%

Conclusion
From the previous calculations it’s obvious that we either can use 5 or 6 trucks.
We chose to use 6 trucks because,
1. This will enable us to optimize the usage of the loaders while not affecting the efficiency of usage of trucks so much.
2. That’s better than using 7 trucks because using seven trucks will increase the cost while decreasing the efficiency of utilization of trucks without increasing the efficiency of loaders.
3. Hence truck capacity = 8 m3
so Productivity = (8/18)*60*8 = 213 m3/day
