Solutions based on understanding customer requirements

The development of projects and spaces reflects the values of our customers; no one invests in buildings without anticipating future benefits. We partner the customer and can provide a value proposition regarding justification, scope, timetable and required investment.

We are also able to honour our value proposition by steering the project towards its targets. Our clear understanding of customer requirements and opportunities enables us to transform them into concrete project targets that can be realised by managing design and construction. This all comes together in the project management process, with the associated requirements of knowledge, skills, instruments, and the motivation to succeed.

Continuously measuring current conditions is the key to successful project steering. If you cannot measure, then you cannot manage. Reacting to feedback forms the foundation for steering the engineering, procurement and construction process towards its targets, while transparency allows for coordinating and overseeing the implementation at all project stages.

Award-winning competency with the HAAHTELA Method

The HAAHTELA Method has helped us manage more than 100 projects to a total value of more than EUR 2.5 billion over the last quarter of a century. We are renowned for our ability to simultaneously manage functionality, quality, costs and timetables.

Anyone can construct on the cheap or at high cost, but it is much more challenging to produce functional high-quality results while managing expenses. Our expertise has been recognised in several prizes awarded to various projects that we have managed.

The Varma Mutual Pension Insurance Company distinguished Haahtela as its 2019 Best Construction Partner, observing that the Haahtela Method was suited to the project, with effective collaboration between the developer, the future main occupier and the other parties involved.

The HAAHTELA Method in construction project management

The HAAHTELA Method signifies a life-cycle project management approach to creating space, from functional space planning to the completed building including life-cycle management. The initial stage of the HAAHTELA Method is based on in-depth, systematic WOP® workplace planning using sophisticated computer models, resulting in spaces having set-out targets considering space properties, investment and operating costs as well as utilization rates, which are in line with the customer’s strategy.

In the HAAHTELA Method the commitment to set out targets is transferred from the project charter to engineering, procurement and construction. The level of target achievement is continuously followed-up by real-time systematic measurements and oversight. This allows for necessary actions to be taken promptly.

The creation of the HAAHTELA Method has required new approaches to processes and information management in construction projects, years of work developing new methodologies, the creation of project and site management organizations that supports the Method and the creation of new types of information models including the harmonization of new information models with existing BIM systems.

We provide the customer, in the capacity as a partner, the services of functional space planners, projects developers, project managers, cost estimators as well as procurement and site management organizations. Haahtela is responsible for contracting and coordination of sub-contracts, site supervision as well as fulfilling the legal obligations placed on the entity initiating the construction project. This brings project development, planning and construction under unitary management, while maintaining operational transparency towards the customer. The approach of the HAAHTELA Method differs from traditional contracting models in every way, with countless projects demonstrating over the years that our Method is the most economical and efficient way of creating space and buildings that satisfy the customer’s functional and quality requirements.
