This $15MM+ agricultural infrastructure project supporting anaerobic digestion and biogas / renewable natural gas (RNG) production.
The project involved construction of a digester-ready livestock facility designed to support organic material handling, process equipment integration, and long-term energy operations. Work required coordination with specialized, vendor-supplied process systems, including long-lead and overseas-manufactured components.
Sentry delivered the project using a Construction Manager at Risk (CMAR) delivery model with dedicated Project Management, while executing multiple self-performed scopes across Electrical, Manufacturing, and South Dakota Service divisions.
This project supports agricultural processing, anaerobic digestion, biogas and renewable natural gas (RNG) production, and utility-adjacent infrastructure, requiring coordinated construction, self-performed specialty scopes, and integration with vendor-supplied systems designed for long-term operational performance.
Overall project leadership and owner coordination
Preconstruction planning and constructability reviews
Budget development, cost tracking, and schedule management
Coordination of subcontractors, vendors, and specialty suppliers
Management of owner-furnished and process equipment
Quality control and safety oversight
Project management focused on aligning construction sequencing with equipment delivery schedules, vendor requirements, and long-term operational considerations.
Sentry served as Construction Manager at Risk (CMAR), providing early involvement, cost
certainty, and construction leadership.
CMAR responsibilities included:
• Preconstruction budgeting and guaranteed cost development
• Constructability reviews and scope coordination across trades
• Trade partner procurement and subcontractor management
• Construction sequencing and site logistics planning
• Quality control, safety compliance, and risk management
• Change coordination and schedule protection
The CMAR delivery model allowed for early collaboration and informed decision-making,
which was essential for managing the scale, complexity, and integration requirements of a
digester-ready agricultural and renewable energy-supporting facility.

This project required extensive coordination with specialty equipment suppliers and
vendors, including manufacturers located outside the United States.
Sentry’s scope included:
• Coordination with vendor-supplied and owner-furnished equipment
• Scheduling and logistics planning for long-lead equipment deliveries
• Integration of overseas-manufactured components into the construction sequence
• Alignment of vendor installation requirements with on-site construction activities
This coordination was critical to maintaining schedule certainty and ensuring equipment
systems were properly integrated into the facility infrastructure.
Each SD Service scope contributed to the constructability, efficiency, and readiness of the
facility, reinforcing Sentry’s ability to support complex agricultural and renewable energy-
adjacent projects through integrated, self-performed capabilities.
