A civil engineering partner for architects, general contractors and brokers
Last updated: November 2026
Quick answer: Most of our commercial work comes by referral from architects, general contractors and brokers, and this page is written for them. Mack Engineering is built to plug into the architect’s, the general contractor’s and the broker’s project: one accountable engineer of record, civil elements modeled in Revit for the architect’s coordination, plan sets designed for first-cycle approval with a pre-submittal meeting on every commercial set, construction administration on the job’s schedule, and a pad site screen that gives a broker’s buyer a written answer in days, not weeks. Proposals are scoped to the parcel and the program and returned within days of receiving them.
Key takeaways
- The architect needs a site that works around the building. The general contractor needs a plan set that clears review and builds without RFIs. The broker needs a written answer before the buyer goes hard.
- Civil elements are delivered in Autodesk Revit so coordination happens on screen, not in the field.
- Mack Engineering is owned by a licensed general contractor. The plans are drawn by people who have had to build from plans.
- Pad site screen for brokers: one parcel, one use, a fit exhibit and memo in days, not weeks, for a fee quoted up front.
- Scoped proposals returned within days of receiving the parcel and the program.

The architect needs a site that works around the building. The general contractor needs a plan set that clears review and builds without RFIs. The broker needs a written answer before the buyer goes hard.
Mack Engineering is built to plug into each of those roles: one accountable engineer of record, proposals scoped to the parcel, and review comment turnaround you can put in your own schedule.
For architects
- Civil elements delivered for your Revit model. We model the site, grading, utilities and hardscape in Autodesk Revit so coordination happens on screen, not in the field. See Revit modeling and BIM coordination.
- Parking and accessible layouts sized to the use, including medical and recreation ratios that exceed the zoning default, before the building is placed.
- Zoning exhibits, hearing support and reviewer coordination so the civil set and the architectural set go in together and match.
- Review comment responses on a committed schedule, written into the proposal.
- One point of contact from concept through construction administration.
For general contractors and site work contractors
- Plan sets designed for first-cycle approval. We hold a pre-submittal meeting with the county on every commercial set, and the stormwater and hydrology report is reconciled to the plans before anything goes in.
- Construction administration that answers RFIs, reviews shop drawings and makes site visits on the schedule the job needs, not on a retainer clock.
- Stormwater facility certification, as-built coordination, maintenance agreements and county closeout handled so the certificate of occupancy is not held up at the end.
- Plans drawn by people who have built. Mack Engineering is owned by a licensed general contractor, and our sister company, Mack Development Group, is a licensed general contractor whose field experience feeds directly back to our engineers. Mack Engineering also provides construction management on the projects we engineer.
- Proposals scoped to the parcel and the program, returned within days of a request.
For commercial brokers
- A pad site screen: one parcel, one use, delivered as a fit exhibit and memo in days, not weeks, for a fee quoted up front. It answers whether the use is permitted, whether the building and parking fit, where detention goes, whether utilities and fire flow are available and where access can come from. See commercial due diligence and feasibility.
- A written read your buyer and their lender can rely on, often before the offer goes in.
- Pre-sale feasibility for listings, so the seller knows what the parcel supports and prices accordingly.
- Commercial feasibility reports for the buyer’s due diligence period if the deal proceeds.
Mack perspective: Because Mack Engineering is owned by a licensed general contractor, we design with constructability in mind. The question we ask on every sheet is the one the superintendent will ask: can this be built the way it is drawn, in this order, with these trucks? Architects get fewer field conflicts. Contractors get fewer RFIs. Owners get a schedule that holds.
How we fit into your project

| Pursuit or listing | Pad site screen or feasibility memo | A go, no-go or conditional answer in writing |
| Schematic design | Concept site plan, parking yield, conceptual stormwater, zoning path | A site that fits the building and the county’s requirements |
| Design development and construction documents | Civil plan set, hydrology report, utility coordination, Revit civil elements | A complete set that goes in with yours |
| Permitting | Pre-submittal meeting, submittal, comment responses, NPDES filing | Fewer review cycles and a known calendar |
| Construction | RFIs, shop drawings, site visits, as-builts, certification, closeout | A clean path to CO |
Where we work
Cherokee, Forsyth, Dawson, Fulton and the North Fulton cities, Cobb, Gwinnett and Hall counties, plus projects in Athens and across Metro Atlanta and North Georgia.

Owner tip: For architects and contractors choosing a civil partner, our guide to hiring a commercial land development engineer lists the twelve questions to ask, and local civil engineer versus national firm covers when each makes sense.

Frequently asked questions
Either. We hold contracts with architects as a subconsultant and directly with owners and developers, and we coordinate the same way in both cases.
On a committed schedule written into the proposal, so your own calendar can rely on it.
Scoped to the parcel and the program, with pre-submittal coordination included rather than added at the end. Fees are quoted in writing before work starts.
Yes. Our team models in Autodesk Revit and coordinates with architectural and MEP models for clash detection and quantities.
Yes. Mack Engineering provides construction management and owner’s representative services on the projects we engineer. Our sister company, Mack Development Group, is a licensed general contractor, and its field experience is why our plan sets are drawn to be built. On most commercial projects we work alongside the owner’s own contractor and coordinate directly with the superintendent.
