The word turnkey often creates more confusion than certainty. One contractor may interpret it as design and interior construction. Another may include furniture, lighting, procurement, installation and commissioning. A client may expect permits, engineering, IT, appliances and final cleaning even though none of them appear in the quotation. When the scope is not defined before pricing, every bidder makes different assumptions and the totals cannot be compared fairly.
A professional turnkey interior scope of work turns the project brief into a responsibility map. It states what must be designed, supplied, installed, tested and handed over; which information the client will provide; where specialist contractors are involved; and which exclusions or provisional allowances remain. This clarity protects the budget and programme before a contract is signed.
This guide explains the main scope sections for residential, hotel, office, restaurant, retail and mixed-use interiors. It also includes a copyable scope template, an inclusion matrix and practical questions for evaluating turnkey quotations.
Turnkey scope categories at a glance
Scope category | What should be defined | Risk when unclear |
Project information | Location, areas, operational goals, standards and required completion date. | The contractor prices the wrong project conditions. |
Design services | Concept, technical design, visuals, schedules, engineering and approvals. | Design gaps appear as variations during construction. |
Construction works | Demolition, partitions, ceilings, finishes, MEP interfaces and builder’s work. | Trade boundaries and site responsibility remain disputed. |
Furniture and equipment | Joinery, loose furniture, upholstery, lighting, appliances and accessories. | Major procurement packages are omitted or double counted. |
Project management | Planning, coordination, reporting, quality, safety and change control. | The client must manage interfaces unexpectedly. |
Logistics and installation | Packing, freight, customs, delivery, storage, protection and installation. | A supply price is mistaken for a completed-project price. |
Testing and handover | Commissioning, snagging, training, manuals, spares and warranties. | The space is physically complete but not ready to operate. |
Commercial boundaries | Assumptions, exclusions, provisional sums, taxes and payment milestones. | The headline quote grows after award. |
1 Define the project outcome and scope boundary
Begin with the intended result. State whether the contractor must deliver a fully operational space, a furnished shell, selected fit-out packages or design and build services only. List every included floor, room, external area and support space. Identify phased areas, landlord zones, existing occupied areas and any work that must occur outside normal hours.
Describe the project type, target quality level, brand or operator standards, user capacity and completion criteria. “Luxury hotel interior” or “premium office” is not a measurable scope. Connect expectations to approved references, material standards, performance requirements and operational objectives.
2 Record existing conditions and surveys
The scope should state who verifies dimensions, existing services and building conditions. Identify available as-built drawings, laser scans, structural information, MEP records, fire strategy, landlord manuals and previous renovation data. Note whether intrusive surveys, opening-up works or hazardous-material checks are required.
Allocate responsibility for discrepancies. A contractor cannot reasonably accept unlimited risk for hidden conditions, but a client should not accept every site difference as an automatic variation. Define the survey stage, reporting process and assumptions used for areas that cannot be inspected before tender.
3 Specify the full design service
List the required design phases: briefing, space planning, concept, developed design, 3D visualization, material selection, technical documentation, construction details and as-built information. State the required number of options, presentations and revision cycles. Identify whether the contractor develops an existing consultant design or leads the complete interior design process.
Define deliverables rather than using the phrase “design included.” Typical outputs include plans, reflected ceiling plans, floor and wall finishes, elevations, sections, lighting layouts, electrical and data layouts, joinery details, door schedules, material schedules, BOQ information and room data sheets.
4 Clarify architecture and engineering coordination
Turnkey interior work interacts with structure, HVAC, electrical power, lighting controls, plumbing, fire protection, data, security, acoustics and kitchen or specialist equipment. The scope must identify which disciplines are designed by the turnkey contractor, which are supplied by the client and who carries coordination responsibility.
State whether the contractor performs engineering calculations, appoints licensed consultants or only coordinates specialist designs. Define required design criteria, authority submissions, clash coordination, builders-work drawings and final record documents. Interfaces should appear in a responsibility matrix, not remain implied.
5 Allocate permits approvals and compliance
Identify planning, building, fire, accessibility, health, food-service, signage, landlord and operating approvals that may apply. State who prepares documents, signs submissions, pays authority fees, attends inspections and closes comments. Local professional appointments and licensed signatories should be identified separately.
The contractor should price compliance with known regulations and project standards, but the tender must state the applicable jurisdiction and approval route. Where requirements are not yet confirmed, include a provisional allowance or defined assumption rather than unlimited responsibility.
6 Define demolition enabling and protection works
For renovation projects, describe demolition limits, salvage items, temporary partitions, dust control, noise restrictions, waste removal and protection of retained finishes. Identify responsibility for disconnecting and making safe electrical, mechanical, plumbing and life-safety systems before removal.
Enabling works may include access preparation, temporary power and water, hoarding, protection, floor levelling, moisture treatment or structural openings. These activities often sit outside finish schedules but can materially affect price and programme.
7 List architectural fit-out trades
Break the construction package into measurable trade sections: partitions, doors, ceilings, plaster, painting, wall finishes, flooring, stone, tiling, waterproofing, metalwork, glass, acoustic treatments and decorative elements. Define preparation, substrates, trims, sealants, fire stopping and interfaces, not only visible finishes.
For each trade, reference the drawing, specification, room or quantity basis. State whether mock-ups, samples, testing and protection are included. If quantities are not final, request unit rates so scope changes can be valued consistently.
8 Define custom furniture and joinery
List every built-in and loose furniture package using consistent item codes. Include kitchens, wardrobes, vanities, wall panels, reception desks, bars, banquettes, bedroom furniture, workstations and storage. State whether the contractor provides shop drawings, engineering, samples, prototypes, hardware, integrated lighting and appliances.
Clarify the material and quality benchmark: substrate, veneer, solid timber, coating, metal finish, stone, upholstery, hardware and internal organization. Define site measurement, production inspection, packing, delivery, installation, adjustment, protection and warranty obligations.
9 Separate FF&E OS&E appliances and accessories
Turnkey does not automatically mean every movable item is included. Identify responsibility for loose furniture, decorative lighting, curtains, rugs, art, accessories, mattresses, linens, tableware, kitchen equipment, audiovisual devices and operational supplies. Use a procurement schedule with included, client-supplied and excluded status.
For client-supplied items, define who coordinates dimensions, electrical loads, delivery dates, storage, installation and damage risk. The turnkey contractor may need to provide connections and supports even when the equipment is purchased directly by the client.
10 Clarify lighting electrical data and controls
Separate decorative lighting from architectural lighting and electrical installation. Define fixtures, lamps, drivers, controls, dimming, emergency lighting, power outlets, distribution modifications, data points, Wi-Fi, audiovisual, access control, CCTV and smart-home or building-management interfaces.
State whether programming, testing and scene setting are included. Confirm who supplies specialist devices, licenses and network hardware. Lighting and control systems should be coordinated with ceilings, joinery, stone and maintenance access before production.
11 Define mechanical plumbing and specialist interfaces
List modifications to air distribution, ventilation, thermostats, sprinklers, fire alarms, plumbing, drainage, water heating and specialist extraction. Clarify whether existing central systems have sufficient capacity and who verifies this. Define testing, balancing, flushing and authority inspection requirements.
Restaurants, hotels, clinics and technical workplaces may need kitchen, laundry, medical, acoustic or equipment specialists. Identify what the turnkey contractor supplies, what it coordinates and what remains a direct client appointment.
12 Include procurement and substitution controls
The scope should define approved manufacturers, material references, acceptable equivalents and the substitution process. Require written approval before changing cost, appearance, performance, maintenance or lead time. Identify long-lead items and deadlines for client decisions.
State whether procurement includes supplier sourcing, comparison, negotiation, purchase orders, expediting, inspection, consolidation and delivery tracking. A contractor that merely purchases selected products is providing a different service from one that manages the complete supply chain.
13 Describe project management and site controls
Define planning, coordination meetings, progress reporting, document control, submittal registers, RFIs, change management, cost reporting and quality inspections. Identify the site manager, project manager and design coordinator expected from the contractor, together with required attendance and reporting frequency.
Health and safety, insurance, permits to work, housekeeping, security and working-hour controls should be aligned with the building and local requirements. The client must also identify its decision-makers and expected approval times because delayed decisions directly affect turnkey performance.
14 Cover logistics installation testing and handover
Specify packing, transport, customs support, unloading, internal distribution, storage, lifting, protection and final installation. Record site access, lift dimensions, loading windows, parking, security checks and restrictions on noise or waste. International projects must state the Incoterm and delivery point.
Completion should include testing, commissioning, snagging, cleaning, client training, as-built drawings, operation manuals, maintenance instructions, warranties, spare materials and keys. Define practical completion, final completion and the defects-liability process so payment is linked to measurable handover obligations.

Currency and taxes | Currency, VAT, withholding, duties and exchange basis. | Prevents different tax and currency assumptions. |
Provisional sums | Named allowances and adjustment method. | Keeps uncertain scope visible. |
Payment terms | Deposit, milestones, retention and supporting documents. | Changes cash flow and contractor risk. |
Programme | Start, design approvals, procurement, construction and handover. | Links price to realistic decision and lead times. |
Changes | Written approval, unit rates, mark-up and time effect. | Controls budget growth after award. |
Warranty | Duration, exclusions, response and defects procedure. | Defines post-handover responsibility. |
Quotation validity | Validity period and price-adjustment conditions. | Protects against expired material and freight pricing. |

- Technical design, shop drawings and engineering coordination are treated as the same service.
- Furniture, decorative lighting, appliances and accessories have no clear supply status.
- Freight, customs, unloading, storage and internal distribution are omitted from the turnkey price.
- Client-supplied equipment interfaces are not included in drawings or construction works.
- Permits, authority fees, specialist consultants and licensed approvals are assumed rather than allocated.
- Testing, commissioning, training, as-built documents and defects response are missing from handover.
How HAN-T structures turnkey interior delivery
HAN-T separates a turnkey package into design, technical coordination, procurement, production, construction, logistics, installation and handover responsibilities. The proposal links these responsibilities to defined deliverables, assumptions and exclusions so the client can evaluate the complete route to an operational space rather than a headline construction price.
During delivery, approved drawings, material codes, furniture data, programme milestones and change records are controlled across the design office, factory and site. This connection is particularly important for projects where custom furniture, architectural finishes and technical services must be installed in a coordinated sequence.
Explore HAN-T’s design consultancy, project management, technical drawing and custom furniture services.
Conclusion
A turnkey quotation is reliable only when the required outcome and responsibility boundaries are documented. The scope must connect design, approvals, construction, procurement, furniture, technical systems, logistics, installation and handover into one coordinated package. Without that structure, a low price may represent a smaller obligation rather than better value.
Before requesting prices, issue a controlled scope, drawing register, inclusion matrix and commercial return format. Ask every bidder to identify assumptions and exclusions. This produces comparable quotations, reduces post-award variations and gives the selected contractor a clearer basis for delivering the project.
