Subcontractor Detailed Program Narrative Report and Methodology

Mumbai International Airport Phase II

Subcontract‐# T2/22.10A&B Supply and Installation of Acoustic Metal & Gypsum False Ceiling Subcontractor Detailed Program Narrative Report and Methodology

1. Introduction.

The intent of this narrative report is to present a description of how the Subcontractor has formulated his detailed program of work. This narrative when read in conjunction with the detailed program shall explain the sequence, logic and planning methodology utilized by the Subcontractor when constructed his baseline program.

The Subcontractor has used a licensed Primavera Project Planner P3.1 Version to develop this program and all the related manpower calculations and histograms and resources.

1.1. Contents

This program narrative consists of the following detailed Sections:

• Contractual Compliance. • Project Phasing Layout and Building Numbering. • Program Structure and logic. • Program Constraints – Definitions. • Resources Loading.

2. Contractual Compliance

This program has been developed based on the correspondences received from the Contractor which are related to the accessibility to site constraints, also it defines clearly the contractual milestones specified for the project completion and trials. Also it is to be noted that all the contractually specified durations have been taken into consideration in this program.

Moreover the sequence and breakdown structure has been also developed based on the instructions received from the Contractor’s planning department.

3. Project Phasing Layout and Building Numbering.

The below schematic Diagram shows the airport phasing according to the priorities defined by the Contractor.

The entire Subcontractor’s scope of work includes the areas defined as Phase II.

Each Phase of the above phases has been internally divided into areas in which each area has been later divided into floors/levels as per the following schematic diagram.

4. Program Structure and Logic.

The program has been divided in addition to the previous two classifications to three general global levels, under each level there are different types of classifications according to the discipline or the physical sequence needed as per the following chart:

Accordingly, the program Layout has been organized using the above different levels of organization and the activities have been Identified in the same manner as per the following table.

This structure is also matching with the general structure specified by the Contractor and sent to the Subcontractor via e-mail sent on 9th March 2011.

4. Subcontractor’s Sequence of Work and program constraint definition.

The priority for each building/Area has been defined previously by the Contractor as per the following graph.

The above priority has been incorporated into the program based on the accessibility to site.

The Accessibility to site also has been provided to the Subcontractor from the Contractor via an email sent on 7th march 2011, where there is clear identification for the Access for each individual building and individual level.

The access dates shows in some buildings that the Subcontractor, will be having access to the same level twice as per the restriction due to the existence of the statue.

It is to be noted that this access in order to be beneficial for the Subcontractor and to help better progress on site, the access shall be preceding by the completion of all the following activities to avoid any interruption or disruption of the Subcontractor’s work:

I. Completion of All Duct works. II. Completion of Cable trays.

III. Completion of Conduits. IV. Completion of Drainage Pipe works. V. Completion of Fire Protection Works.

VI. Completion of Plumbing Works. VII. Completion of all any other Mechanical/ Electrical works.

The Subcontractor will not proceed with installation of sub frames or paneling until access document is officially signed off as being complete, by all responsible interfacing or preceding Subcontract Trades.

The construction activities have been developed starting from the access date milestone that has been constrained with an early start constraint as specified by the Contractor followed by all the subsequent activities.

As per the project specifications and the supplier’s specification with reference to DIN EN 13964, the installation of any acoustical panels will require a controlled environment in terms of Temperature as well as the Humidity, this will require the Contractor to give the Subcontractor the access associated with a closed envelop and supplied with a wild air in order to control the Temperature and the Humidity.

Therefore, the Contractor is required to provide a schedule of the façade works completion dates along with the wild air required for the installation process and this will be again incorporated in the program.

The regimen of access controls to a great extent the peaks of the Manpower needed as the access to the all buildings will be mostly given to each bundle of buildings in one time span, this controls the existence of the Subcontractor’s manpower and creates peaks and dips in the manpower histogram.

All the subsequent activities are linked to this start milestone as well as to the related activity that has direct physical relation with this activity. Also all the construction activities have predecessor activity related to the design, production, and delivery to

site, this have controlled the closure of all open ends and ensures proper critical path development.

The program has included some control activities that could be the driving factor to proceed with the next step, in all cases these driving activities are related or should be given by the Contractor to allow the Subcontractor to proceed forward. One of these critical control activities is the receipt of the chandleries locations and hanging point that will be affecting the commencement of design of the Subcontractor’s substructure and bridging drawings and accordingly will affect the production of the substructure and panel materials.

At the end of each phase, there is a particular section defining the finish milestone dates for that particular phase as well as the project opening and trials.

5. Subcontractor’s Material quantity and manpower Loading

In order for better monitoring and controlling over the project, the program has been fully loaded with the material quantity. This will help the Subcontractor to clearly determine the required material from each type of the ceiling material for a certain period, and to help the control over the inventory.

The Manpower histograms also help the Control over the required number of Manpower per month or even per week. This will provide a clear image about the peaks that need special measurements.
