2) CONSTRUCTION BIDDING PROCESS

When looking at the Design Profile, We can imagine the grandeur and beauty of the Project after it is completed.

However, in order to "transform" a Building located on “papers” become a Construction “reality” can be observed directly with the eyes, touch with hand, feel with other senses, … is not a simple thing.

So, stage of selecting the Construction Unit (Contractors) reputation, Being qualified to execute the Works is an extremely important step.

To select a Contractor, the Investor (Client) will Procurement organization.

Hereafter ACI Construction Company Limited as a Contractor, Please share with customers “Bidding Process” as follows:

Bidding Diagram

3) CONSTRUCTION PROCESS

For the Project to have a quality construction process, The least error occurs. Then there should be a Construction process clear, rigid.

ACI Construction Company Limited uses the Network Button Construction Diagram to go up "Construction process" Construction.

Construction Diagram of Network Nodes, also known as “Network Diagram Method” Directed Graph method is applied (network structure) into the algorithms to Schedule and Organize the Construction.

In each Network button will contain information such as: Numerical order, Job name, Amount of work, Number of employees, Number of equipment and machines, Completion time.

Connection arrows between Network Nodes show traction (necklace) of the Works.

In the Network Node Construction Diagram. We use Gloves – Gantt to control the construction progress of the Works.

In addition, we also apply the Oblique Progress chart, Horizontal Progress, Vertical Progress to optimize Network Node Construction Diagram.

Glove Road Concept (Gantt):

On the diagram, The Glove Line is indicated by prominent red arrows.

We detail the Works (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) are the Works located on the Ganges Road (Gantt).

Gloves Road (English is Critical Path) is the shortest time (maybe) to complete Construction.

During construction, We always strictly control the Gangway to ensure the construction progress.

The works that are not on the Ganges Road are the jobs that can be moved depending on the actual construction.

In reality, It is inevitable that problems may arise, affect the completion progress of the Works. Flexible use of Network Node Diagram, Controlling the Glove Road and flexibly deploying the works that do not belong to the Glove Road will help us handle well the problems that may occur during the Construction process..

Above, is the Construction Process that We apply to a Project built from A – Z. Include: Rough construction, Complete construction, Interior construction.
