In this article, we delve into what a turnkey project entails, as well as relevant aspects to consider before committing to this type of contract.

What is a turnkey project?

A turnkey project is a type of contract agreed upon with a contractor for them to handle all or most of the construction process. It applies to any type of work, whether it's a complete new build or a renovation.

The service provider (the contractor) signs the agreement with the client, which concludes with the handover of the completed work. The construction company is responsible for everything, including administrative procedures. This approach is particularly popular in residential construction projects, commercial buildings, and public works.

Features 

Turnkey projects are distinguished by several key characteristics:

Process Simplification

The client does not have to worry about managing different suppliers and contractors, as a single contractor handles all phases of the project, simplifying the construction process.

Project Control

With a single construction company, they are responsible for both the initial design and the execution of the work, right up to the final handover. Therefore, each stage is planned and executed in a coordinated manner.

Fixed Budget

The project price is fixed by both parties, allowing the total cost to be known before construction begins. This way, the client has a clear understanding of the necessary investment.

Adherence to Deadlines

The turnkey project includes a guaranteed delivery timeline. Before starting the project, the contractor will define a schedule with dates for all phases and commit to meeting them.

Speed and Time

By hiring a single company for the entire project, they will have everything required to develop it without needing to negotiate with anyone else, thus streamlining processes, including licensing procedures.

Why choose a turnkey project?

Choosing a turnkey project offers numerous advantages for clients. Some of the key reasons include:

Simplicity and convenience

For individuals unfamiliar with the construction world, embarking on such a project can be overwhelming. As such, a turnkey project simplifies the process, as the client only has to deal with a single entity.

Integrated project management

This integrated management includes everything from initial design to construction and final delivery, providing a complete and hassle-free solution for the client.

Risk reduction

When all responsibilities are delegated to a single company, the client avoids dealing with multiple contractors and suppliers. This minimizes risks due to poor communication or lack of coordination between different parties, reducing the possibility of delays and quality issues.

Cost control

By setting a fixed price at the start of the contract, the contractor becomes responsible for any additional costs, giving the client greater peace of mind. This cost control is especially valuable in large projects, where there can be significant budget fluctuations.

Time savings

By handling all project phases, the provider can optimize execution times, resulting in faster delivery.

Access to experts

To streamline processes and ensure quality work, turnkey project providers typically have a team of experienced professionals in various areas, ensuring higher quality in the final outcome.

How does it work?

Generally speaking, the operation of a turnkey project can be summarized in these stages:

  1. Initial consultation: the client and contractor discuss the project's needs and expectations; subsequently, they establish the objectives, budget, and delivery timeline.
  2. Design and planning: based on the client's wishes, the provider develops a preliminary design and an execution plan. Then they handle the necessary permits and licenses.
  3. Construction: once the design is approved, civil construction begins. The provider will coordinate all necessary subcontractors and suppliers to carry out the work.
  4. Supervision and quality control: throughout the construction, the provider will maintain ongoing supervision to ensure the project's progress and that established quality standards are met.
  5. Final handover: the big day of the "turnkey" handover arrives. Once the work is completed, a final inspection is carried out to ensure everything is in order. The client receives the keys, marking the project's completion.

What's included?

A turnkey project includes a variety of services, depending on the provider and the type of project. However, common elements typically include:

Architectural design

The contractor is responsible for creating plans and technical specifications for the project.

Permit management

Obtaining all necessary licenses and permits to carry out the work, and paying fees and taxes such as VAT or property transfer tax.

Construction

This not only refers to the execution of the work (foundations, structure, electrical and plumbing installations, finishes, etc.), but also to the purchase of materials, labor, and the necessary permits for the project's construction.

How much does it cost and how long does it take?

Each type of project, whether a single-family home, a commercial building, or a public work, has different costs and execution times; this will depend on multiple factors, such as location, design complexity, ground conditions, among others. Similarly, material and labor prices vary significantly depending on the region of Spain.

What to consider before investing in a turnkey contract?

Before committing to a turnkey contract, it is important to consider several aspects:

Provider reputation

Researching and verifying the experience and reputation of the contracting company is of utmost importance. Look for references and review previous work, ensure the company has a proven track record of on-time and on-budget delivery, and is capable of handling a project of the scope you will present.

Clarity in the Contract

Ensure that all project details are clearly specified and accurate in the contract, including timelines, costs, and warranties. Knowing the exact scope of work will prevent misunderstandings and future disputes.

Warranties

A turnkey project offers long-term benefits to the client, such as quality assurance for the work and materials used, which helps minimize future operating or maintenance costs.

How to Find a Quality Turnkey Contract?

To find a quality turnkey contract, here are some practical steps:

Research the Provider

Conduct a thorough search for experienced contractors in the area; include the internet in your search, where you can also read testimonials and reviews. Ask friends and colleagues if they have worked with any trusted providers. Meet with providers in person to discuss the project and assess their professionalism and responsiveness. Ask for references from their previous work.

Request Quotes

Request several quotes to compare prices and services. Ensure that all providers offer the same scope of work for a fair comparison.

Visit Ongoing Projects

If possible, visit ongoing projects by the contractors you are considering to assess the quality of their work.

Disadvantages and Challenges 

While turnkey projects offer many advantages, they also present some disadvantages and challenges:

Dependence on the Provider

The quality of the final outcome largely depends on the competence and reliability of the chosen provider. For this reason, you should choose a trustworthy company that understands the industry and its needs.

High Costs

Generally, the upfront cost of a turnkey project is higher than the price of building a project in phases, partly because it includes the profit margin of the real estate developer or contracting company.

Less flexibility

A turnkey solution offers the client less flexibility to make changes to the design or project features, and if changes are made, we must be aware that these modifications will disrupt all delivery dates and costs that may have been set at the beginning of the contract.

Example of Turnkey Construction Contracts

An example of a turnkey construction contract could be the building of a custom home. In this case, the contractor would be responsible for all aspects of the project, from obtaining permits, construction costs, and materials, to delivering the home ready for occupancy. The contract would specify the house design, construction timelines, total cost, and warranties offered.
