Optimizing Cost Efficiency and Sustainability: Modular Construction Strategies for the Sierra Blanca Motorsports Park

by: A. Khaalis Wooden

Contingency measures have been established to enable the seamless integration of modularization through off-site construction and engineering for the Sierra Blanca Motorsports Park project. The development plan highlights several features and strategies where such modular approaches can provide significant advantages:

  1. Phased Development Approach:
    The project already proposes a phased development strategy, prioritizing high-revenue facilities such as the multi-purpose road course. Modular construction can be integrated into this approach, particularly for components like grandstands, administrative buildings, and spectator amenities. Pre-fabricating these structures off-site would reduce on-site construction time and minimize disruption.

  2. Modular Grandstands:
    The inclusion of modular grandstands with scalable capacity (3,000 to 7,500 spectators) is explicitly mentioned in the design enhancements. Utilizing off-site construction for these units ensures faster deployment and flexibility to adjust capacity based on demand.

  3. Environmental Features:
    Infrastructure such as greywater recycling systems, rainwater harvesting units, and autonomous vehicle testing facilities could benefit from modular design. Pre-assembled systems can be transported and installed on-site with minimal environmental impact, aligning with the park’s ESG (Environmental, Social, Governance) commitments.

  4. Eco-Friendly Concessions and Shaded Seating:
    Modular units for eco-friendly concessions and shaded spectator areas can be pre-fabricated with sustainable materials, streamlining their integration into the broader park infrastructure.

  5. Technology and Renewable Energy Systems:
    Facilities such as EV charging stations and solar power arrays could be modularized. Off-site assembly of these systems would enhance quality control and reduce on-site installation complexity.

  6. Corporate and Training Facilities:
    Multi-purpose spaces for corporate events and training programs can be developed modularly, offering flexibility in design and future expansion.

The project can achieve faster timelines, cost efficiencies, and enhanced quality control while maintaining the innovative and eco-conscious vision of the Sierra Blanca Motorsports Park by leveraging modular construction

 

To calculate the cost savings from implementing off-site/modular construction and engineering, we will assume typical cost reduction percentages based on industry data. Off-site construction generally offers savings of 20% to 30% on labor costs, 10% to 15% on material costs, and 25% to 50% reduction in construction time. This time savings also leads to lower indirect costs, such as equipment rental and site management expenses.

The following is an estimated breakdown of cost savings:

Savings Breakdown

  1. Labor Costs:

    • Savings: 20%-30%

    • Off-site construction reduces the need for on-site labor, minimizing labor-intensive activities.

  2. Material Costs:

    • Savings: 10%-15%

    • Prefabrication optimizes material usage, reducing waste.

  3. Construction Time:

    • Time Savings: 25%-50%

    • Faster project timelines reduce expenses for equipment rentals, site utilities, and overhead costs.

  4. Quality Control:

    • Reduced rework and delays lead to indirect savings.

Let us calculate potential savings using hypothetical costs for the Sierra Blanca Motorsports Park based on common project budgets.

Assumptions

  • Total project cost: $50 million

  • Labor: 30% of total cost (~$15 million)

  • Materials: 50% of total cost (~$25 million)

  • Overheads and contingencies: 20% (~$10 million)
