Design Office and Construction Management (CM)

Currently, Miyako City has positioned the sixth year after the earthquake as a "development period" after reconstruction, and various efforts are being made to develop the city into a more vibrant and attractive city than before the earthquake. One of them is the construction of a new government building in the central city area where Miyako Station is located, which is aiming to be completed in July 2018. Mitsubishi Jisho Design Co., Ltd. is participating in this project "Miyako City Center Urban Base Facility Construction Management Support Service" as a Construction Management (CM) company. Many people may think, "Is the design office a CM?", but our company has been doing commercial work under the name of supervision for a long time. In addition, the CM Office was established in 2000, when it was the business headquarters of Mitsubishi Estate Co., Ltd., architectural design and construction supervision Co., Ltd., and is currently working as the CM Department of Mitsubishi Jisho Design Co., Ltd. From the initial Cost Management center, we now have a diverse business menu throughout the project to support the client.

CM is defined as "a construction manager (CMr), who is the assistant or agent of the client, who maintains technical neutrality and stands on the client's side, and performs all or part of various management tasks such as design review, construction ordering method review, schedule management, quality control, and cost management at each stage of design, ordering, and construction." (*)

Many design firms may think, "That's something we do as part of architectural design and construction supervision work." When I explain CM, I say, "CM in Japan is a profession established in construction projects that combines part of the client's work with the management work that designers have traditionally been responsible for." Perhaps because the third-party nature of CM was emphasized in the early days of CM, there is still a lack of understanding of CM, which has now expanded to a wide range of work, and I think there are still many design firms that have built a "wall" between themselves and CM.

The CM method has been adopted not only in Miyako City, but in many construction projects in the Tohoku region during the earthquake reconstruction effort. One reason for this is that the flexible role of CM has been recognized anew in the emergency situation of earthquake reconstruction. In public works outside of Tohoku, an increasing number of local governments are adopting CM to manage construction projects. In 2016, the Ministry of Land, Infrastructure, Transport and Tourism created a "Collection of Case Studies of the CM Method Used by Local Governments, etc.", which lists many advanced examples from both the public and private sectors.

Furthermore, the 2014 amendment to the Act on Promotion of Quality Assurance of Public Works (Quality Assurance Act) made it possible to adopt diverse procurement methods. A symbolic example is the National Stadium. After the original plan was scrapped, a new tender was held, and the joint venture of Kengo Kuma, Azusa Sekkei, and Taisei Corporation Corporation was selected based on their proposal. Construction work is currently underway, and as can be seen from this, procurement methods other than the traditional method of separating design and construction are now being implemented.

Traditionally, the private sector has adopted a free "ordering method." Furthermore, the "diverse ordering methods" that have been adopted in the public sector, such as DB from design development, ECI method, and adoption of third-party Construction Supervision, now seem to be influencing the private sector in the opposite direction. Rather than a simple choice between separate design and construction or all-in-one method, an increasing number of clients are seeking better quality at a reasonable price by involving many capable people and organizations in construction projects. As the "way" of building construction becomes more diverse, more advanced management is required.

In order for design firms to continue to develop as leaders in the architectural world, they must see this situation as an opportunity, remove the barriers between architectural design and construction supervision and CM work, integrate and develop their know-how, and transform into organizations that can manage entire construction projects.
