In order for a building to be designed and construction undertaken according to the needs of the client and to be maintained in an appropriate manner, it is necessary to follow the steps mentioned below.

1. Planning stage

We define requirements for designing and given conditions in collaboration with clients and examine the concept planning to attain the images of the architectural structure which clients desire. Also, we conduct a site survey and an existing building survey as needed.

  • • Site survey and existing building survey
  • • Consideration and planning of project schedule
  • • Consideration and planning of ideas for basic concept

2. Basic design stage

Based on requests and given conditions, we formulate a basic plan of the architectural structure. We fix on the images of facade of the building, interior design and color. Moreover, we clarify the completed figure of the building by investigating enactments, criteria and techniques required in implementing the plan as well as by doing a case study of construction schedule and construction cost.

  • • Survey on enactments and regulations
  • • Cost study
  • • Consideration and planning of basic design

3. Detailed design stage

We make various decisions by considering the basic design from the point of view of both design and technique. On that basis, we draw the design required to order construction works. Along with this, we start necessary procedures and detailed meetings with government staff.

  • • Engage in prior consultation with administrative institution and begin procedure of application for building confirmation
  • • Make a drawing of detailed design
  • • Formulate building budget

4. Stage of selection of contractor and contract with it

Based on the design drawing, construction works are ordered. We confirm that the construction contract between the clients and the contractor fully includes the content of the design and give advice on it.

  • • Advice and additional instruction for selecting a contractor
  • • Confirmation of content of the construction contract
  • • Support in the contract procedures

5. Stage of construction supervision

We check whether the construction works are implemented based on the contract. We work toward smooth implementation of the construction works in partnership with the contractor in order for the objects indicated in the drawings and specifications to be completed within the term of works. In addition, we make final decisions of finishing materials and colors in this stage.

  • • Explanation regarding content of the design and discussion about the construction works
  • • Confirmation of the draft for construction works made by the contractor
  • • Confirmation of materials and physical samples
  • • Proposal for finishing materials and colors
  • • Check up of administrative institution and response to handing over

6. Maintenance system

We propose an appropriate maintenance plan so that the buildings are used according to the aims confirmed in the stage of designing and provide long-term performance.

  • • Conduct surveys on age deterioration and troubles
  • • Formulate repair plans
  • • Make a design for improvement and estimate for it


1. General picture of the consulting service

When implementing overseas school construction projects, in addition to the construction designing and supervision, we believe that it is necessary to consider the needs and educational circumstances of a wide range of stakeholders who have rarely been considered as clients such as students, teachers, school staff, parents and local residents. We also believe that it is of great importance to encourage the ownership and participation of those people in our projects. In order to achieve this, the Social Development Unit was established in 2000, aiming to provide highly detailed assistance. The staff working in this unit specialize in education, gender and community participation. Our service ranges from educational survey under the school construction project funded by Japan's Grant Aid (Official Development Assistance) and capacity building and training through a software component program for the same project.

We have conducted survey and capacity building in more than 10 countries in Asia, Africa Central-America and Middle-East. We have carried out, not only technical surveys and soft-component supports of school construction projects through Japanese Grant Aid, but also preparatory surveys/ collections of information/ verification surveys/ evaluation surveys for Japan International Cooperation Agency (JICA) and monitoring surveys for Japan Platform (JPF). Hence, we would like to expand our scope of service to development survey as well as project formulation study in the field of education and social development.

2.1 Survey

Stakeholder meeting
in Nicaragua

When making the basic design for school construction projects funded by Japan's Grant Aid, we conduct a wide range of surveys about the country's educational policies, educational administration, current situation and the needs of schools and the community. Based on the results of the survey, we examine the validity of the project as a Grant Aid project and also propose the selection of the project schools, scope and content of the project in Stakeholder meeting in Nicaragua order to implement the project effectively. Moreover, we propose the necessity of software component.

  • < Main survey items >
  • • National development plan, education policies and education sector plan
  • • Actual situation and priority issues of the education sector
  • • Trend of international donor aid in the education sector
  • • Educational situation and social and economic status in the area where the project is planned
  • • Local capacity and system to implement the project
  • • School management and maintenance system
  • • Social surroundings to be considered in conducting the project, such as gender and area disparities in educational opportunity and learning environment

2.2 Capacity Building and Training

Maintenance workshop
in East-Timor

It is important that the provided school facilities are used in an appropriate manner for a long time. In order to achieve this, we have engaged in implementation of workshops for the administrators and school staff as well as creation of a school maintenance manual for them, aiming to improve their capacity of school management and maintenance. We conducted this kind of software program in Tanzania, the Philippines, East-Timor, Vietnam, and Senegal.


1. Building deterioration diagnosis

After a certain period, performance, materials and equipment of buildings begin to deteriorate due to physical and chemical factors such as rainwater, air pollutants, ultraviolet rays, and temperature change. When the scope of deterioration expands with age and therefore the durable period of the buildings is reduced, performance, materials and equipment of buildings will have problems. Survey and diagnosis will be conducted to prevent the falling of cladding tiles, water leaks, degradation of indoor environment caused by harmful materials related to the sick house and deterioration of equipment.
For any building, such as office buildings, schools, residential complexes, factories, houses, we conduct seismic diagnoses, durability diagnoses of existing exterior walls, deterioration diagnoses of equipment and plumbing pipes, and then we evaluate the condition and performance of a building based on the results.

1.1 Visual Survey

We conduct a visual survey of the building. Based on these results, we examine the necessity of a comprehensive survey and a detailed survey.

1.2 Comprehensive survey

We browse documents such as drawings and specifications and an up-to-date history of maintenance. We also interview the administrator of the building. Along with this, specialists conduct surveys by category of external facing, internal facing, framework, exterior, and equipment. According to need, we investigate the functioning of equipment and the presence of asbestos.

1.3 Detailed survey

Based on the comprehensive survey, we conduct a chemical survey, an x-ray survey, a supersonic survey, endscope survey of items and parts in which there is concern for serious deterioration and alternation.

Survey on pump operation   X-ray survey
on extent of piping corrosion
  Endscope survey
on internal pipe condition
  Supersonic survey
on extent of piping corrosion

1.4 Summing up the results of the survey and making reports

We explain the situation category by category with pictures and propose several courses of action in the report.

2. Renewal design

2.1 Formulating a preliminary renewal design and quantity surveying and cost estimation.

According to need, we formulate a preliminary renewal design and conduct quantity surveying and cost estimation for upgrading.
