多项填空题

David is trying to conduct the Time-phased budget and cash flow analysis for the first four activities of the project. Assuming 30 working days per month, and the duration of each activity and labor budget is shown below: ID Description Predecessor Duration Budget A Prepare Site None 20 $4,000 B Pour Foundation A 35 $15,610 C Erect Frame B 45 $45,000 D Roof B 65 $70,200 (1) Allocate the labor proportionally to the time worked each month. Please calculate the cumulative budget at the end of each month from month 1 to month 4. The cumulative budget of M1 is [Fill in the blank] ; M2 is [Fill in the blank] ; M3 is [Fill in the blank] ; M4 is [Fill in the blank] . (2) With an initial payment of $20,000, Karim and Emanuel made the payment plan at the end of every month to David as follows Month 1: $10,000 Month 2: $100,000 Month 3: $0 Month 4: $10,000 Please calculate the cash flow balance for each month. Cash flow balance at the end of Month 1: [Fill in the blank] Cash flow balance at the end of Month 2: [Fill in the blank] Cash flow balance at the end of Month 3: [Fill in the blank] Cash flow balance at the end of Month 4: [Fill in the blank]

The question requests two separate calculations for a project budget and cash flow, but the provided data and structure are not perfectly aligned for a straightforward, unambiguous solution. I will walk through how to approach each part step by step, point out where the given numbers imply a specific method, and note potential ambiguities that could lead to different results. Part (1): Time-phased cumulative budget by end of each month - We have four activities with durations (in days) and budgets: A (20 days, $4,000), B (35 days, $15,610) with predecessor A, C (45 days, $45,000) with predecessor B, and D (65 days, $70,200) with predecessor B. The project timeline is divided into months with 30 working days per month. - The instruction says: allocate the labor proportionally to the time worked each month. A common interpretation is: for each month, allocate to each active activity a portion of its budget proportional to how many days of that activity occur in that month, relative to the activity’s total duration. Then sum these monthly allocations across activities to obtain the cumulative budget by the end of each month. - Step-by-step method (assuming the standard interpretation above): 1) Determine, for each activity, how many days fall into each calendar month (given the start times implied by precedence): - A runs from day 1 to day 20 (month 1 only). Therefore, A contributes entirely in Month 1. - B starts after A (i.e., after day 20). B runs fro......Login to view full explanation
