JK Prestige Constructor is a family-operated Jacksonville GC that self-performs framing, drywall, finish carpentry, concrete, and roofing. The trades we do not self-perform — mechanical, electrical, plumbing, specialty flooring, glass, and others — we source from qualified trade partners who have earned a place on our approved list.

If you are a trade contractor looking to work with JK on Jacksonville-area projects, here is what the qualification process looks like and what separates trade partners who get consistent work from those who do not.

What JK Looks for Before the First Call

Before a conversation about a specific project, JK confirms that a trade contractor meets baseline requirements:

Florida Contractor License

Every trade contractor working under JK's GC license must hold the applicable Florida contractor license for their trade:

No Florida license, no conversation. This is not a preference — it is a legal requirement. JK's GC license is on every permit. If a trade sub pulls their own sub-permit under a project where JK is the GC of record, the sub must be licensed. If JK pulls the trade permit, the sub must be operating under JK's direct control with a licensed qualifier on site.

Insurance Requirements

JK requires a current certificate of insurance before any trade partner accesses a JK jobsite:

Insurance certificates with expiration dates during the project period must be renewed before expiration. JK tracks this and will pull a trade contractor from the site if coverage lapses.

OSHA 30 for Supervisory Personnel

JK is an OSHA 30 shop. Trade partners are expected to have OSHA 10 minimum for all field workers and OSHA 30 for foremen and supervisors. On hospital, occupied-building, and industrial projects, JK requires OSHA 30 documentation before mobilization.

On a JK jobsite, OSHA compliance is not optional, and the supervisor who shows up without documented OSHA training goes back to the truck until documentation is provided.

The Bid Process

Once a trade partner is on JK's approved list, they receive bid invitations for relevant project types. Here is what JK expects in a bid response:

Complete Scope Coverage

A bid that responds to only part of the scope of work, with verbal additions in a meeting, does not work at JK. Bids must address the full scope document provided. If an item is excluded, it must be explicitly called out in writing with the reason.

JK uses a scope sheet for each trade package. Trade partners bid against the scope sheet line by line. This is not a preference — it is how JK avoids the change order theater that most Jacksonville GC-sub relationships are built on.

Realistic Schedule Input

Trade subs that bid JK projects must provide their crew size assumptions and timeline input. A mechanical sub who says they can mobilize in three days and complete rough-in in two weeks for a 12,000 sqft commercial project either has a plan to back it up or does not belong on the project. JK's project schedule is built on real input from real crews.

Single Point of Contact

Every JK trade partner provides a named project manager or foreman who is the direct contact for that trade on the project. Calls do not go to an answering service. Texts get answered the same day. JK's principal is available by direct number — the trade partner's lead is expected to be equally reachable.

What JK Expects During Construction

Clean Handoffs

Trade subs working under JK clean up their work area daily. Material staging is pre-coordinated with JK's superintendent — materials do not arrive and get piled wherever is convenient. Debris from the trade sub's scope is their debris to manage.

Punch List Ownership

When JK issues a punch list to a trade partner, the expectation is completion in five business days or a written schedule with a completion date. Punch list items that drag for weeks cost JK money and create owner dissatisfaction. Trade subs who return calls and close punch lists keep getting bid invitations.

No Unapproved Substitutions

If a trade sub specifies a product in their bid and substitutes a different product in the field, that is a violation of the contract scope. Every substitution requires written approval from JK's principal before installation. This protects the owner, protects the GC, and protects the sub from warranty exposure on a product they did not specify.

How JK Builds Its Approved Trade Partner List

JK's approved list is built from three sources:

  1. Direct referral from other trade contractors — trade subs who perform well refer other trades; this is the most reliable signal
  2. Verified project history — JK calls references from comparable-scope work, not from the best two projects on the contractor's resume
  3. Trial project — a first project is typically smaller scope, assessed carefully; consistent performance earns larger scope

Jacksonville is a construction market where most GCs and trade subs know the same names. A trade contractor's reputation for showing up, completing clean work, and closing punch lists is known before JK picks up the phone. A reputation for over-promising and under-delivering is also known.

Trades JK Currently Sources from Partners

Trades JK does NOT source out (self-performs):

If you are a mechanical, electrical, or plumbing trade contractor in Jacksonville who performs clean work, carries current insurance and licenses, and has OSHA-trained field personnel, call JK. A principal answers.

No call center. No coordinator. A JK principal reviews every inquiry and replies with a real number, not a range, not a follow-up form.

Frequently Asked Questions

Does JK require trade partners to be on any prequalification list?
JK maintains its own internal approved trade partner list. You do not need to be on any municipal or national prequalification list to work with JK, but Florida licensing and current insurance are required before any work begins.
Will JK consider trade contractors outside of Jacksonville?
For projects in NE Florida (Duval, St. Johns, Nassau, Clay counties), JK prefers local trade partners who can mobilize quickly and are familiar with local AHJ requirements. Out-of-area trade subs are considered for specialty work not available locally.
How long does it take to get on JK's approved trade partner list?
After submitting a request with license and insurance documentation: 5-10 business days for initial review. If information is complete, you may receive a bid invitation on the next relevant project.
Does JK use the same trade subs across all project types (residential, commercial, hospital)?
Some trade partners work across all project types; others are specialized. JK's hospital and occupied-building projects have more stringent ICRA compliance and OSHA requirements. Trade partners who work on hospital projects must demonstrate familiarity with ICRA barrier protocols.
What is the fastest way to get a bid invitation from JK?
Submit your Florida license number, current insurance certificate, and a brief project history to JK's principal directly. The first call is a 20-minute conversation about what you do and where you work. If it fits a current project need, an invitation follows quickly.
