Modular Construction Consulting Services for Every Stage of Development

Modular construction is reshaping the built environment—accelerating schedules, improving quality, reducing waste, and enabling more predictable project execution. At Hillmann, we understand the unique opportunities and challenges that come with modular development. With over 40 years of experience supporting complex real estate and construction projects nationwide, we provide a full suite of multidisciplinary services designed specifically for modular programs.

Our team works across the entire lifecycle of modular projects—from early feasibility and design through fabrication, transportation, installation, and closeout—to help clients achieve consistency, accountability, and speed to market. We align technical expertise with real-world constructability to ensure that modular units integrate seamlessly with site-built components and overall project goals.

Hillmann’s comprehensive modular services include:

Factory Assessment

A modular project is only as strong as the capabilities of the factory producing it. Hillmann performs detailed evaluations of modular factories to determine production capacity, quality control systems, workforce competency, and overall viability.

Our services include:

• Initial Factory Review – In-depth inspection and analysis of modular manufacturing facilities prior to lending or project approval.
• Factory Opinion Letters (Periodic or As-Requested) – Ongoing assessments during fabrication, including observation of completed or in-progress units, production analysis, and reporting.

These evaluations help clients make informed decisions and reduce risk before, during, and after unit fabrication.

Project Review & Design Advisory

Modular development requires coordination between factory production, site preparation, and overall project objectives. Hillmann’s multidisciplinary team reviews plans, design packages, cost structures, and development strategies to verify constructability and alignment with budget and schedule.

Our project review services include:

• Pre-development analysis
• Conceptual and schematic design review
• Technical constructability reviews
• Cost consultancy
• Development advisory and risk identification

This rigorous process helps maintain consistency across factory-built and site-built components while supporting efficient project execution.

Lender Representation & Construction Risk Management

As a trusted national provider of lender services, Hillmann plays a critical role in managing risk for modular projects. Our team represents lenders throughout the construction process by coordinating with borrowers, contractors, and modular manufacturers.

Our lender representation services include:

• Loan Monitoring – Site and factory observations, construction progress reviews, schedule tracking, change order evaluation, and requisition package review.
• Disbursement & Fund Control – Mitigating financial risk by overseeing funding, verifying work-in-place, and ensuring appropriate allocation of construction funds.

These services are designed to keep modular projects on track, transparent, and compliant.

Building Sciences & Quality Assurance

Hillmann provides environmental and building science services tailored to modular projects. Whether units are produced in a factory or delivered to the project site, quality control and environmental safety are paramount.

Our capabilities include:

• Mold and moisture testing (baseline and delivery confirmation)
• Thermal imaging
• Moisture metering
• Airborne and surface sampling
• Condition reporting

By verifying unit integrity throughout the process, we help clients avoid issues that can delay installation or occupancy.

Property Due Diligence for Modular Sites

Before modular units arrive at a site, it’s critical to understand existing conditions and potential risks. Hillmann’s due diligence services support developers, lenders, and owners through every phase of evaluation and entitlement.

Key services include:

• Phase I Environmental Site Assessment (ESA)
• Zoning analysis
• ALTA/NSPS land surveys
• Environmental assessments and compliance reviews

These due diligence offerings ensure modular projects proceed with clarity, compliance, and confidence.

Construction Advisory & Development Management

Modular construction requires seamless integration between factory schedules and field operations. Hillmann’s Construction Advisory team brings deep experience in owner’s representation, program management, design management, and cost oversight.

Our scope includes:

• Budget development and cost management
• Schedule creation and monitoring
• Procurement and bid management
• Design coordination
• Contractor, vendor, and consultant management
• Site observation and project documentation
• Phasing, logistics, and occupancy strategy

We provide the oversight needed to keep modular and site-built components aligned, reducing friction and maximizing efficiency.

Safety is essential on any project—but modular programs add unique complexities, including hoisting, unit transport, and factory-to-site transitions. Hillmann’s Construction Site Safety team provides:

• Onsite safety management
• Construction safety audits
• Site-Specific Safety Plans (SSSP)
• Health & Safety Plans (HASP)

Our certified safety professionals help mitigate risk, prevent accidents, and support regulatory compliance.
