Assignment 3

Construction of a Residential Complex Using the Activity-on-Node (AON) Method

Company Y is a construction company that has been awarded a contract to build a residentialcomplex. They aim to efficiently manage the project using the Activity-on-Node (AON) method in their Critical Path Method (CPM) analysis. The project involves multiple activities with interdependencies and strict timelines.

Project Details:

Construction of a residential complex comprising three apartment buildings

Key deliverables include site preparation, foundation construction, building erection, interior work, and landscaping

Project duration: 12 months

A: Site Preparation/ \/ \B: Foundation C: Building Erection Construction\ /\ /D: Interior Work| E: Landscaping

Activity Descriptions and Duration Estimates:

A: Site Preparation (4 weeks)

Clear the site and prepare it for construction activities

Tasks: Clearing vegetation, leveling the ground, establishing temporary facilities

B: Foundation Construction (10 weeks)

Build the foundations for the apartment buildings

Tasks: Excavation, pouring concrete, reinforcing structures

C: Building Erection (18 weeks)

Construct the apartment buildings

Tasks: Structural framing, roofing, exterior finishing

D: Interior Work (20 weeks)

Complete the interior work of the apartments

Tasks: Plumbing, electrical installations, flooring, painting

E: Landscaping (6 weeks)

Complete the outdoor landscaping and beautification

Tasks: Planting trees, laying pathways, installing outdoor amenities

Project Constraints:

Building permits must be obtained before commencing construction activities.

Availability of construction materials and equipment must be considered for timely execution.

Construction work should adhere to local building codes and regulations.

AON Method Analysis:

Determine the dependencies and sequence of activities based on the AON diagram.

Calculate the earliest start time (ES), earliest finish time (EF), latest start time (LS), latest finish time (LF), and total float for each activity.

Identify the critical path, which consists of activities with zero total float and determines the project's minimum duration.
