Civil Engineering for Apartment Developers

Why Developers Choose Hagen Engineering

Hagen Engineering has designed civil engineering plans for over 15,000 apartment units across North Carolina, South Carolina, Tennessee, Georgia, Alabama, Arkansas, Virginia, and Florida. That depth of multifamily-specific experience means we understand the site conditions, regulatory frameworks, and deal timelines that drive apartment development in the Southeast — and we design accordingly.

When you work with Hagen Engineering, your project is led by a principal engineer — not handed off to junior staff after the proposal is signed. Our partners are directly involved in design decisions, agency coordination, and project delivery. You get senior-level engineering judgment on every call and every submittal, which translates to fewer review comments, faster approvals, and designs that actually work in the field.

We have established relationships with planning departments, water and sewer authorities, DOT offices, and environmental agencies across all 8 states we serve. These relationships are not abstract — they mean we know what specific reviewers expect, how to structure submittals for faster turnaround, and when to pick up the phone instead of waiting in queue. Developers who have worked with us across multiple jurisdictions consistently report shorter permitting timelines compared to their experience with other firms.

Our fee structure reflects the efficiency of a focused practice, not the overhead of a large corporate firm. You get multi-state licensing, deep multifamily expertise, and a single point of contact for your entire portfolio — without paying the premium that comes with firms that staff layers of project managers between you and the engineer doing the work.

Full-Service Scope for Multifamily Sites

Multifamily apartment communities require a comprehensive civil engineering scope that addresses every site system — from initial feasibility through construction closeout. Hagen Engineering delivers the full range of services as a single-source consultant, eliminating the coordination gaps and finger-pointing that come with splitting work across multiple firms.

Our standard multifamily scope includes:

• Site feasibility & yield analysis
• Site/civil engineering design (grading, drainage, layout)
• Stormwater quality & quantity design
• Water distribution & fire flow analysis
• Sanitary sewer collection design
• Erosion & sediment control
• Permitting & agency coordination
• Earthwork takeoffs & cost optimization
• Construction administration

This integrated approach ensures that every system is designed in coordination — stormwater infrastructure works with site grading, utility routing avoids conflicts with building foundations, and erosion control measures are sequenced to match actual construction phasing. The result is a cleaner permit review, fewer RFIs during construction, and a project that moves from design to vertical construction without unnecessary delays.

Built for Scale — Portfolio Highlights

Our multifamily track record speaks in numbers: 36 apartment communities completed, over 15,000 units designed, and projects delivered across 8 Southeast states. This is not theoretical capability — it is a documented portfolio of communities that are built, occupied, and performing.

Signature projects in our portfolio include Ardmore at Flowers (396 units, North Carolina), Views at Athens (387 units, Georgia), Foley Apartments (360 units, Alabama), Hudson at Carolina Colours (360 units, North Carolina), and Ardmore at Prosperity Crossing (360 units, Tennessee). These large-scale communities required complex grading, multi-system utility design, regional stormwater compliance, and coordination with multiple reviewing agencies — all delivered on schedule.

Our project range extends from 30-unit infill communities with tight site constraints to 396-unit developments spanning 40+ acres. Regardless of scale, every project receives the same principal-level attention to design quality, constructability, and permitting strategy.

Designed for Repeat Partnerships

The best measure of an engineering firm is whether developers come back. Many of our current clients are repeat developers with three or more projects in our portfolio — and they return because we deliver consistent quality, predictable timelines, and competitive fees across every engagement.

For developers managing multi-state portfolios, working with a single engineering firm that holds licenses across 8 Southeast states eliminates the overhead of sourcing, vetting, and managing separate consultants in each market. We already know the reviewing agencies, the local design standards, and the stormwater requirements in every jurisdiction we serve. That institutional knowledge compounds over time — the second project in a given municipality moves faster than the first, and the third faster still.

We understand developer timelines and deal structures. When a site is under contract with a due diligence deadline, we mobilize feasibility analysis immediately. When construction financing requires a permitted set by a specific date, we manage the permitting schedule backward from that deadline. Our team is structured to handle concurrent projects without capacity bottlenecks — so taking on a new project does not delay an existing one.

If you are building apartment communities across the Southeast and need an engineering partner who can scale with your pipeline, we are built for exactly that relationship.
