Study: Accelerating Drywall Installation in the Metro Office Complex Project After a

Delay

Background

The Metro Office Complex Project involves constructing a large commercial building that has

encountered significant delays in the drywall installation phase. These delays are attributed to

supply chain disruptions and an unexpected shortage of skilled labor, putting the project's overall

timeline at risk. The project management team is tasked with developing a strategy to accelerate

the drywall phase to recover lost time without compromising safety or work quality.

Objective

To quantitatively analyze the impact of the delays on the drywall installation phase, propose

multiple recovery strategies, and calculate the additional costs and time required to implement

these strategies efficiently.

Assumptions and Data Provided

$$ Total Drywall Area: $200,000$ sq$.$ ft$.$

$$ Drywall Crews: $4,$ each originally expected to install $800$ sq$.$ ft$.$ of drywall per day.

$$ Original Timeline for Drywall Work: $90$ days.

$$ Delay Duration: $10$ days.

$$ Labor Hours Available per Day per Crew: $8$ hours, $5$ workers per crew.

$$ Cost of Labor per Hour per Worker: $$25$ regular, $$37\mathrm{.}50$ overtime $(1\mathrm{.}5$x regular rate$).$

$$ Cost of Hiring an Additional Crew $($Including Training$)$: $$7,000.$

$$ Investment in Automated Drywall Tools per Crew: $$15,000.$

$$ Daily Productivity Increase with Automated Tools: $25\%.$

$$ Average Cost of Drywall Materials per sq$.$ ft$.$: $$2.$

$$ Estimated Cost Increase for Expedited Drywall Delivery: $15\%.$

Tasks:

$1.$ Quantitative Impact Assessment:

$$ Calculate the financial impact of the $10-$day delay, including lost labor productivity and

increased material costs.

$2.$ Recovery Plan Development & Cost$-$Time Calculation:

$$ Option $1$: Overtime Work: Assess the additional hours and labor costs needed to catch up

within the revised timeline.

$$ Option $2$: Hiring Additional Crews: Evaluate the cost$-$effectiveness and timeline impact

of adding more crews.

$$ Option $3$: Investing in Technology: Calculate the cost and timeline benefits of adopting

automated drywall tools.

$3.$ Risk Management and Quality Control:
