CM at-risk, GMP delivery, preconstruction services, and project controls for commercial owners in Northeast Florida.
JK Prestige Constructor Corp is Jacksonville's most trusted construction management firm — offering CM at-risk and GMP delivery for commercial owners and developers who need more than a traditional hard-bid GC relationship. With 500+ projects completed, 94 verified 5-star reviews, and 0 recordable OSHA incidents in 2024, we are preferred by institutional owners, hospital systems, and large developers across Northeast Florida. Our CM at-risk model engages JK Prestige in preconstruction to provide budget estimates, value engineering, constructability reviews, and subcontractor pre-qualification — all before design is complete. Jacksonville's commercial market generated $2.8B in permits in 2024, and the most competitive owners in that market use CM delivery to control cost and schedule. All work complies with the Florida Building Code, is permitted through Duval County Building Services, and adheres to OSHA standards. We are AGC-affiliated and deliver preliminary GMP budgets within 48 hours.
"Owners who have been burned by a lump-sum GC's hidden margin or lack of transparency deserve a better model. CM at-risk gives you a partner in preconstruction, a transparent fee, and a GMP you can trust — because we built the number together." — J. Karras, Founder & CEO, JK Prestige Constructor Corp
Transparent CM delivery from conceptual budget through close-out documentation.
Conceptual (SD-level), schematic (DD-level), and GMP (60–90% CD) budget estimates issued on a cost-per-CSI-division basis. Value engineering alternatives presented with cost and schedule impact for each. Constructability reviews identify coordination issues and missing information before permit submission, preventing the RFIs and change orders that inflate cost during construction.
GMP established from 60–90% construction documents with a defined allowance structure for incomplete scope, a detailed Schedule of Values, and a transparent fee disclosure. Open-book subcontractor bid results reviewed with the owner before award. Any savings below the GMP are shared with the owner per the negotiated savings-sharing formula in the CM agreement.
Line-item SOV established at GMP execution and allocated across all CSI divisions and major work components. Monthly pay applications are prepared with verified percentage completion for each SOV line, supported by lien waiver collection from all subcontractors and material suppliers. Applications are submitted in G703/G702 AIA format compatible with all standard owner payment audit processes.
Numbered RFI log with issuance date, responsible party, due date, and response tracking — updated weekly and distributed at each OAC meeting. Submittal register tracking all specification sections requiring submittals, with approval status, revision cycles, and incorporate-into-work dates. Overdue responses escalated to the design team and owner before they impact the critical path.
Weekly work plans developed with foremen and subcontractor superintendents using Last Planner System methodology. Three-week lookahead schedules identify constraints — long-lead material, inspection hold points, utility connections, design decisions — at least 21 days in advance. Percent Plan Complete (PPC) metrics are tracked and reported at each OAC meeting as an objective measure of schedule reliability.
A transparent, owner-aligned delivery process from project inception through close-out.
The CM agreement establishes the fee structure, GMP-triggering document completion threshold, savings-sharing formula, and preconstruction scope. JK Prestige begins preconstruction services immediately — attending design team meetings, providing budget estimates at each design milestone, flagging constructability issues, and developing the preliminary project schedule before permit submission.
JK Prestige pre-qualifies subcontractors on bonding capacity, OSHA safety record, current workload, and reference checks — before issuing bid packages. Subcontractor bids are reviewed open-book with the owner, and award decisions are made transparently. The GMP is established from the awarded subcontract values plus JK Prestige's disclosed CM fee and general conditions.
Long-lead material procurement (structural steel, mechanical equipment, electrical gear, elevator equipment) is initiated before permit issuance wherever possible. JK Prestige's early procurement strategy prevents material lead times from controlling the project schedule, which is a common and expensive failure mode on commercial projects that delay procurement until after permit issuance.
Weekly OAC meetings with the owner, architect, and JK Prestige review schedule performance (PPC), open RFIs and submittals, pay application status, pending change orders, and the 3-week lookahead. JK Prestige's principal attends every OAC meeting — not a project manager without authority to make decisions or commit to recovery plans.
JK Prestige prepares a complete close-out documentation package: as-built drawings, O&M manuals, equipment warranties, testing and balancing reports, commissioning documentation, lien waivers from all subcontractors and suppliers, and the final SOV reconciliation. The package is delivered to the owner within 30 days of CO — not months later as a contractual afterthought.
Licensed, bonded, and industry-affiliated for construction management in Florida.
Transparency, owner-direct accountability, and preconstruction expertise that hard-bid GCs cannot provide.
JK Prestige's CM fee is disclosed and negotiated upfront — not embedded in an opaque lump sum. Owners know exactly what they are paying for overhead, profit, and general conditions on every pay application. Open-book subcontract awards mean no hidden buyout profits.
The highest-leverage cost reduction opportunities on any commercial project occur during design — not after the GC is mobilized. JK Prestige's preconstruction engagement allows value engineering alternatives to be evaluated against structural, MEP, and aesthetic requirements before they are designed into the contract documents.
CM delivery requires direct owner-CM communication to function correctly. JK Prestige's principal participates in every preconstruction design meeting, every OAC meeting, and every change-order negotiation — maintaining the communication quality that CM delivery requires from a small, owner-focused firm.
The GMP commitment gives owners a defined maximum cost exposure while retaining the benefits of early engagement and collaborative delivery. JK Prestige's GMP includes a defined allowance structure and contingency plan for incomplete scope — not a blanket contingency that is drawn down without owner visibility.
Common questions from commercial owners, developers, and institutional clients.
A traditional (lump-sum hard-bid) GC bids a fixed price against completed documents with no preconstruction involvement. A CM at-risk engages the owner in preconstruction, provides budget estimates and value engineering, then commits to a Guaranteed Maximum Price (GMP) with a transparent fee structure. The CM's fee is disclosed; any savings below the GMP can be shared with the owner.
A Schedule of Values (SOV) is a line-item breakdown of the contract sum allocating the total price across each major work component. Each monthly pay application draws from the SOV based on verified percentage completion. A properly structured SOV prevents front-loading and gives the owner transparent basis for evaluating each payment request.
A Request for Information (RFI) is a formal inquiry from the contractor to the design team requesting clarification about construction documents. JK Prestige maintains a numbered RFI log, tracks each from issuance through response, escalates overdue responses, and incorporates responses into the construction documents before the affected work is performed.
CM at-risk fees for commercial projects in Jacksonville typically range from 5% to 12% of total construction cost, depending on project complexity, size, and preconstruction services included. This fee is transparent and negotiated upfront — unlike a hard-bid GC's embedded margin, which is buried in the lump sum and not visible to the owner.
CM at-risk delivery is most beneficial when the project begins before design is complete, when the owner wants cost transparency and fee disclosure, when early GC involvement in value engineering will reduce overall cost, or when the owner wants a collaborative relationship rather than an adversarial lump-sum contract structure.
