Five phases. One team. The capital and the execution, together.

Nothing about this method is exotic. It is how a development should be run, phase by phase, each one ending at a gate. The difference is one team doing all of it, every day, so nothing slips through the cracks.

Gate at the end of every phase · 02 and 03 run in parallel once plans can be priced

Select a phase to jump to it.

Phase 01

Diligence

Path to approval and costs, before capital is committed to predevelopment. We determine how the project gets approved, complete the diligence on compliance, soft costs and hard costs, map everyone with a say over the property, and line up who should design it. Everything done here sets up what happens next.

Saves time

The approval route and every authority’s review time known before design starts, set against real hearing calendars.

Saves money

No design fees or deposits spent on a project that cannot be approved or does not work financially.

Path to approvalComplianceSoft and hard costsEvery authority mappedDesign team qualified
  • One intake, so the owner, Grex and every firm work from the same facts, followed by a gap analysis of what is missing and who has to provide it
  • Our own research on the ordinance, design standards and compliance requirements. Current zoning decides the route: design and submit, special use permit, variance or rezone
  • Every entitlement and permit the project needs, listed, with what each one requires the property to be designed to
  • Everyone with jurisdiction or a say over the property mapped, utilities included, with each one's review time and construction lead time feeding the schedule
  • Concept layouts tested on the actual parcel before a licensed design professional is hired
  • A cost basis for approvals and construction, with every number labeled by where it came from. Early figures are a basis for decisions, not a price
  • Architects, engineers, surveyors and consultants qualified on experience, capacity, reputation, cost and local relationships, with predevelopment proposals in hand
  • Highest and best use, and whether the project fits the owner's intended use, stated plainly
Gate 1 · Path known: approvals mapped, cost basis set, design team ready to hire
Phase 02

Predevelopment

Plans move from concept to fully approved. The design team starts on day one with our basis package: how the project gets approved and exactly what has to be designed. Their fee goes to design, not to research.

Saves time

Submittals timed to the next board deadline, and no redesign loop after the plans are priced.

Saves money

Design fees go to designing instead of research, and every option is priced before the owner chooses it.

Design team hiredPlans to approvalHearingsEstimate at quantities
  • The basis package on day one: the approval path, the rules the design has to meet, site constraints, easements, the utility map and the unit-count basis
  • Design and cost run together. Once plans carry measurable quantities, typically by design development, we estimate from a takeoff, so design decisions are made with their cost known
  • For manufactured and modular projects, plans developed around the homes being placed, worked directly with the manufacturer
  • Pre-application meetings with the staff and boards who will review the project
  • The submission package and narrative, and representation of the owner before planning commissions and councils
  • Conditions of approval tracked through satisfaction, local and state

Phase 03 · runs with 02

Preconstruction

Runs alongside predevelopment once plans are detailed enough to price. The budget is set before bids, the market is tested on complete plans, and the project reaches construction-ready.

Saves time

Permits, home production slots and utility work lined up before notice to proceed, so the work starts on day one.

Saves money

Scope gaps caught on paper instead of as change orders, and the procurement savings measured against the Control Budget.

Control BudgetHard bidsContractPermitsNotice to proceed
  • Contractor qualification, started while approvals are still moving
  • The Control Budget, set after construction documents and before bids, approved by the owner and accepted by the lender
  • Bid documents on a Grex schedule of values with a quantity schedule, so every bidder prices the same thing
  • Hard bids only on complete plans. Bids leveled on scope before price, because a blank line is not a zero
  • Best and final offers and an award recommendation, with recommended owner-side contract terms, for the owner's decision
  • The Control Budget revised to the executed contract. Both are kept, and the difference is the procurement savings
  • In parallel: construction permits, home orders and production slots, owner-furnished items, utility construction scheduling, the lender package, insurance and bonds
  • The draw process set up with title or the lender before work starts
Gate 3 · Construction-ready: contract executed, permits in hand, budget locked, notice to proceed
Phase 04

Construction

Every claim of progress checked against what the site shows, every dollar tracked to proof, every delay on the record, and the owner updated every week.

Saves time

Issues flagged before they become delays, while there is still float to protect the finish.

Saves money

Only verified work is paid, and every change is priced against the budget before it reaches the owner.

Schedule of recordVerified progressDrawsImpact ledgerWeekly updates
  • One schedule of record, held by Grex. The contractor's schedule merged in, the baseline never overwritten, a three-week lookahead every week
  • Fixed cameras from the first day of construction, with drone and 360 capture on a set cadence
  • Pay applications checked against the site record. Sworn statements and lien waivers collected, and draws run through title
  • Change orders priced against the schedule and the budget before they reach the owner
  • Homes and owner-furnished items sequenced with the plant and the site, with qualified, licensed crews brought in
  • Weekly owner updates, and anything major the day it happens

Closeout

Punch, certificate of occupancy, the final accounting and turnover to operations, and the record that makes the next project faster.

Saves time

Punch closed with evidence, so occupancy and the first day of operation are not held up.

Saves money

Final cost reconciled, retainage and waivers closed, nothing left open to pay for later.

How we work with the design team

Who is hired as the engineer and architect, and what they are asked to carry, is one of the most consequential decisions in a project. Grex sets the design team up to do its best work.

  • Scope, deliverables and review cadence are defined at selection: the design team knows what construction-ready means for this jurisdiction and this delivery method, from day one.
  • Materials and methods are decided while the plan set is developing, in collaboration with the licensed design professionals, not after bid day.

We are never a trade ourselves, and we do not hold the design team’s seat.

B · Who we manage

One team at the center. Every firm, every phase.

We represent the owner. We qualify each firm, bring it under contract for the owner and manage its work for as long as it is on the project.

C · How a project is run

The capital and the whole project, run by one team.

On most projects the money and the work are watched by different teams. The owner and the lender see a spreadsheet. The design team, the jurisdiction and the contractor each see their own piece. Nobody holds the whole project. Grex does, in every phase, with our own development managers and our own project intelligence, so the owner's time goes to decisions instead of coordination.

Project leadership

Accountable for the owner's capital, timeline and decisions.

Field project management

On site at the moments that matter, and on the cameras every day between them.

Schedule and cost control

One schedule of record and one budget, kept current.

01
Paid only for work in place

Every pay application is checked against the camera, drone and 360 record. Work that matches moves to a draw. Work that does not is resolved first, so the owner never pays ahead of the site.

02
A budget with no surprises in it

Spent, committed and priced are never mixed, and a bid is never counted as a commitment. The owner knows the real number on every line, across land, predevelopment, preconstruction, construction and owner-furnished costs.

03
Capital called when it is needed

Each cost line is tied to the work it pays for. When the schedule moves, the cash forecast moves with it, so equity and loan draws are timed to the work instead of called early and carried.

04
Issues seen before they cost

Cameras, drones and the schedule are read together every day. A light crew, an open trench or a late inspection is flagged while it is still a risk and there is float left to protect the finish. A delay that does happen is recorded with its cause, the days it added and what it cost.

05
Decisions while they are still cheap

Schedule, budget and risk are rated every week. When a decision is needed, the owner gets the options with their cost and schedule effect early enough that the cheaper option is still on the table. Nothing reaches the owner before a Grex reviewer has checked it.

06
Every project informs the next

Verified costs, durations and approval timelines from each project carry into the next one, so estimates start from what projects like it actually took.

Development management: common questions

What is a real estate development management firm?

A development management firm runs a real estate project on the owner's behalf, as the owner's outside development team. Grex Dynamics runs projects from due diligence through closeout: the path to approval, design, procurement, construction and the capital tracking that ties them together, for housing and commercial projects nationwide.

What does a development manager do?

A development manager validates how the project gets approved and what it will cost, qualifies and contracts the design team for the owner, runs entitlements and public hearings, sets the budget, runs procurement, coordinates the home manufacturer on factory-built projects, and manages construction through closeout, with one schedule of record, tracked capital and weekly owner updates.

What is the difference between an owner's representative and a development manager?

An owner's representative is the owner's advocate on a project, typically through design and construction. The owner's rep coordinates the architect, engineers and contractor, monitors budget, schedule and quality, reviews pay applications and change orders, and reports to the owner. A development manager does that work and takes on more of the project: due diligence, the path to approval, the capital plan and budget, procurement and closeout, from land to an operating property.

When should an owner hire a development manager?

When the project would benefit from a specialized, focused team whose only job is driving its success. Ideally that is before capital is committed to design, so the path to approval, the compliance requirements and the costs are known first. Grex also joins projects already underway, including mid-construction.

How much does a development manager cost?

Fees depend on the scope and size of the project. Development managers are commonly paid a monthly fee during predevelopment and a fee tied to project cost during construction. Grex scopes and prices each engagement by phase after a first review of the project.

How long does it take to get a development project approved?

It depends on the jurisdiction and the route. A by-right site plan approval can take a few months, while a rezoning, special use permit, variance or state review adds time. Grex maps the route, every authority involved and their hearing calendars during diligence, so the timeline is known before design starts.

How does Grex track a project's money?

Grex requests the proposals and runs the RFQs and RFPs for consultants, contractors and manufacturers, levels the bids and recommends awards for the owner's decision. Once money is committed, every dollar is tracked in three states, spent, committed and priced, across five cost groups, with the cash forecast tied to the schedule. Draws run through title with sworn statements and lien waivers.

How does Grex verify construction progress?

Fixed cameras run from the first day of construction, with drone and 360 capture on a set cadence, and every pay application is checked against that record before it reaches a draw. Grex representatives are on site at key milestones and whenever the project needs it or the owner requests it.

What kinds of projects does Grex work on?

Housing and commercial projects: manufactured housing communities, modular and townhome communities, apartments, outdoor hospitality and RV parks, new or expansions of operating properties, nationwide. That includes workforce housing, market-rate, high-end and resort-style, short-term and transient stays, and 55+ and retirement communities.

When is the Control Budget set?

After construction documents are complete and before bids are taken. The owner approves it and the lender accepts it. When the construction contract is executed, the budget is revised to the contract amount. Both are kept, and the difference between them is the procurement savings.

Does Grex replace the architect, engineer or general contractor?

No. Grex qualifies the licensed architects, engineers, contractors and consultants, brings them under contract for the owner, and coordinates their work. Grex is never a trade itself.

Does Grex work with home manufacturers?

Yes. On manufactured, modular and park model projects, the manufacturer is another party Grex works with in every phase: plans, pricing, production slots, delivery and set.

Where does Grex work?

Nationwide, across the United States.
