Using the precedence diagram below and associated data in the attached table, create the following. You must calculate the daily values in the table first. 40 points 1. A daily cash-loaded bar chart and cash flow histogram based on the project’s early dates. 2. A banana curve of cumulative daily cash flows showing both the early and late start dates. Week 5: Construction Scheduling MS Project schedule activity The following table shows a set of activities from a Construction Project, the duration of the activities and logic sequence of the tasks have been defined together with the resources required to complete these tasks. 60 points Use Microsoft Project to schedule this project, create and assign Resources. This project has a limitation of resources with the maximum amount limited as follows: (Engineer = 8 hours/week; Laborers = 20 hours/week; Crane = 5 hours/week; Consultant = 2 hours/week). Choose start date 12/1/20. Follow the following Homework Hints 1) Add a summary activity at the beginning to name your project. 2) To enter duration in weeks, go to: File_Options_Schedule_Duration is entered in: Weeks 3) All activities must be set as Fixed Duration in Task type. 4) When creating resources, the maximum allowed units for each resource have to be changed as a percentage per total week hours (e.g. Laborer: 20 maximum hours per week = 20/40 = 50%). If the result is a decimal enter it as is, even if Project rounds it up. 5) When assigning resources, either on the split screen or using the assign resources button, to activities in the field “Units’, again the working hours have to be changed as a percentage per total week hours (e.g. Engineer: 5 hours per week = 5/40 = 12.5%) to yield the total hours required to finish the activity. 6) The total hours of work to complete the activities should not change (e.g. for Preliminary Planning requires 5 engineers hours per week working for 10 weeks for a total of 50 hours) Week 5: Construction Scheduling 7) If you are in auto schedule mode, as you assign resources to activities, the software will try to allocate them automatically to solve conflicts, to see the unleveled schedule you can always click on Clear Leveling. 8) The Resource Leveling tool will not fix all the Limited Resources conflicts, you will have to redistribute the resources by adding appropriate weeks to the activities with resource conflicts, when doing this Project will ask you if work hours have increased or resources will work fewer hours, choose appropriately. Requirements: 1) Print the Gantt chart views before and after Leveling Resources (Show in one page Task Name, Duration and Gantt chart only). 2) Print the Resource Sheet. 3) Print the Resource Usage sheet showing the Resource Name and Total Work hours for each resource and activity (Just the first page, left side), before and after Resource Leveling. 4) Choose one resource that is conflicting and print the Resource Graph of this resource showing where it has conflicts before and after Resource Leveling. 5) Use the final leveled schedule and research appropriate hourly wages for Field Engineer, Laborers and Consultants, and hourly rates for a Crane (You can use RSMeans or any other reliable source for the US). Input this cost in the Resource Sheet and obtain the weekly cash flow for the project.

Paper For Above instruction

The complex nature of construction project scheduling demands precise coordination of activities, resources, and cash flow management to ensure project success. This paper explores the critical steps involved in developing construction schedules using Microsoft Project, creating cash flow visualizations, and managing limited resources effectively. Emphasizing a step-by-step approach, it demonstrates how to develop a cash-loaded bar chart, a cash flow histogram, and a banana curve for cumulative cash flows, based on early and late start dates. Additionally, it details the process of scheduling activities, assigning resources under constraints, leveling resources to resolve conflicts, and calculating project costs based on current wage rates, culminating in an optimized project timeline with cash flow insights.

Introduction

Effective construction scheduling is fundamental to project management, impacting timelines, resource utilization, and financial performance. Accurate scheduling facilitates proactive decision-making, allows for resource leveling, and supports cash flow planning. Modern project management tools like Microsoft Project streamline these processes by providing visual and analytical capabilities essential for complex project coordination.

Developing Cash Flow Visualizations

The first step involves calculating daily cash flows, which are essential for financial planning and risk management. Using the project’s early start schedule, a daily cash-loaded bar chart illustrates how funds are spent over time, highlighting peak periods of expenditure. Complementarily, a cash flow histogram provides a clear visual comparison of inflows and outflows, aiding project managers in resource allocation and financial contingency planning. For a comprehensive view, a banana curve displays cumulative cash flows, mapping the early and late start dates to highlight potential delays or acceleration opportunities (Fleming & Koppelman, 2010).

Scheduling Activities with MS Project

The project scheduling process begins with entering activities, their durations, and logical dependencies in Microsoft Project. All activities are set as Fixed Duration to maintain consistent task lengths regardless of resource allocation changes. A summary activity at the project start enhances clarity and organization.

Resource limitations are critical; hence, each resource’s maximum weekly hours are adjusted to reflect realistic working capacities, such as 8 hours for engineers, 20 hours for laborers, 5 hours for cranes, and 2 hours for consultants. When assigning resources to tasks, their units are expressed as percentages of total weekly hours, ensuring that total hours remain constant. For example, assigning 12.5% units for engineers working 5 hours per week yields the correct total of 50 hours for preliminary planning (Project Management Institute, 2017).

Resource Leveling and Conflict Resolution

Auto-scheduling and resource leveling are used iteratively to resolve conflicts caused by resource limitations. Before leveling, the Gantt chart, resource sheet, and resource usage views help visualize over-allocations. After applying resource leveling, adjustments prolong activity durations or add buffer weeks to balance resource demand. A resource graph pinpoints specific conflicts, enabling targeted redistribution of workloads.

Cost Estimation and Cash Flow Analysis

Once the schedule is leveled, current wage rates for each resource type are researched using credible sources like RSMeans. These rates are input into the resource sheet to calculate weekly costs, which are aggregated to generate project cash flow. Accurate cost estimation informs project budgeting, funding requirements, and financial risk mitigation.

Conclusion

Construction project management hinges on meticulous scheduling, resource allocation, and cash flow management. Utilizing tools like Microsoft Project, project managers can visualize, analyze, and adjust schedules to meet project constraints and financial objectives. The integration of detailed cash flow visualizations and resource leveling results in a realistic and achievable project timeline, minimizing delays and cost overruns.
