For New Construction, Renovations, and Building Additions
In industrial and commercial construction, the best projects feel predictable. The budget stays anchored, decisions get made on time, and the jobsite runs safely and efficiently. That kind of predictability comes from a disciplined process and a true design-build delivery model, where one team is accountable for both design and construction under a single contract.
This is exactly why we lead projects with a repeatable, proven roadmap. It gives our clients clarity early and fewer surprises later.
At Eagan Building Group, we use the same 10-step Design + Build Process across project types, and we tailor the due diligence, sequencing, and field execution to match what you are building or upgrading. Below is how the process works for new construction, renovations, and building additions or expansions, and what is unique about each.
Why Design-Build Works for Industrial and Commercial Owners
Design-build gives owners a single point of responsibility. One coordinated team aligns scope, cost, schedule, and constructability from day one.
Because design and construction move forward together, we can validate scope sooner, price with more confidence, and make smarter decisions before work ever hits the field. That is how we keep projects predictable.
When you are trying to keep a facility operational, coordinate mechanical and electrical systems, satisfy code requirements, and beat a procurement timeline, the last thing you need is design and construction pulling in different directions.
New Construction: The 10 Steps (And What They Really Mean)
1) Due Diligence
We fully vet owner requirements, site constraints, soil conditions, surveys, and utility scoping because the site drives everything downstream. We will recommend environmental due diligence when the site history warrants it.
2) Design Development
We define code requirements, validate performance needs such as workflow, clear heights, loading, power demands, and future flexibility, and create concept plans with early architectural budgeting.
3) Preliminary Budgeting
We build a detailed project budget, typically targeting within plus or minus 10 percent, by verifying scope line by line and pressure-testing assumptions. We do not guess. We verify the scope early so you can make informed decisions.
4) Budget Review
We align scope and priorities with stakeholders. This is where we value-engineer intelligently. We protect the mission-critical elements while finding savings where they do not compromise operations.
5) Final Detailing
We complete construction drawings and technical specifications that are coordinated for permitting and for building efficiently in the field.
6) Contract and Pricing
We finalize a lump sum price and execute the construction contract with clear scope, schedule, and allowances.
7) Procurement
We lock in long-lead and critical materials early, such as steel, electrical gear, rooftop equipment, specialty doors, and structural packages. This helps keep supply chain constraints from dictating your start date. Early procurement is one of the most effective ways to protect the schedule.
8) Permitting
We secure permits and prepare for site mobilization so the transition from paper to field is clean and controlled.
9) Construction Phase
Active construction management and execution of the building plan includes safety leadership, schedule control, quality checkpoints, and proactive issue resolution.
10) Closeout
Closeout includes punch list completion, inspections, documentation, and project handover so your team can occupy and operate with confidence. A clean closeout is part of doing the job right, not an afterthought.
Renovations: The 10 Steps (With Renovation-Specific Risk Controls)
Renovations can carry different risks than ground-up work. Unknown conditions, hidden utilities, hazardous materials, and occupied-facility constraints can derail projects if you do not plan for them upfront.
Our renovation process is built to reduce disruption, manage risk early, and keep your facility running safely.
1) Due Diligence (Renovation Edition)
We vet owner requirements and conduct targeted investigations. This often includes hazardous material considerations, MEP system surveys, and site or building improvement planning. When hazardous materials may be present, we plan accordingly and follow applicable safety and regulatory requirements.
2) Design Development
We define code requirements and reconcile what is shown on drawings with what is actually in the building. We develop concept plans and architectural budgeting with constructability and phasing in mind.
3) Preliminary Budgeting
We build a detailed budget and clearly separate what is known from what may require contingency due to concealed conditions. We still target a disciplined budgeting model, often aiming for plus or minus 10 percent where scope and existing conditions allow. We also identify the highest-risk areas early so there are fewer surprises during demo.
4) Budget Review
We align phasing, safety plans, shutdowns, and operational constraints with stakeholders. This is especially important for active facilities.
5) Final Detailing
Final drawings and specifications include phasing notes, temporary protection requirements, and MEP cutover sequencing.
6) Contract and Pricing
We finalize lump sum pricing with a scope that clearly states assumptions, allowances, alternates, and unit rates when appropriate. The goal is to reduce surprises.
7) Procurement
Renovations often require specialty materials and replacement equipment. We coordinate procurement to match phasing and help keep the facility operational.
8) Permitting
Permitting can be more nuanced in renovations due to change-of-use triggers, accessibility upgrades, and existing condition requirements.
9) Construction Phase (Renovation Edition)
Active construction management and execution of the renovation plan includes dust control, safety separation, temporary utilities, and schedule coordination with operations.
10) Closeout
Closeout includes punch list, inspections, documentation, and handover. It may also include training and turnover sequencing that supports your operational ramp-up.
Additions/Expansions: The 10 Steps (Integrating Old and New Smoothly)
Additions and expansions combine the logistics of new construction with the integration requirements of an existing facility.
The goal is simple. Expand your space while protecting the performance and safety of what is already operating.
1) Due Diligence
We verify site capacity such as utilities, access, and stormwater, assess existing building conditions, and plan how the addition will connect to structure, envelope, life safety, and MEP systems. We will recommend environmental due diligence when the site history warrants it.
2) Design Development
We develop concepts that make the tie-in clean. This includes circulation, loading, fire separations, code paths, and system capacity verification.
3) Preliminary Budgeting
We budget both the addition and the integration work, including service upgrades, shutdown windows, and temporary systems.
4) Budget Review
We align budget, phasing, and schedule expectations with stakeholders. Expansions often have business-driven occupancy dates, so alignment here matters.
5) Final Detailing
We finalize drawings and specifications with a strong focus on tie-in sequencing, envelope transitions, and coordinated MEP integration.
6) Contract and Pricing
A clear contract scope is essential, particularly around tie-ins, existing conditions, and owner-furnished or contractor-installed items.
7) Procurement
Additions can be procurement-heavy. We plan early for structural steel, electrical gear, rooftop equipment, envelope systems, and other long-lead items.
8) Permitting
We manage permits for both the addition and any triggered upgrades to the existing building.
9) Construction Phase
We build the new footprint while protecting the active facility, then execute tie-ins with planned downtime windows and commissioning readiness.
10) Closeout
Turnover is often staged. It may include partial occupancy, phased inspections, system documentation, and handover that supports operations from day one.
