01Survey/Assessment
Prior to designing/planning a building, we conduct various surveys and analyses, which we consider essential to ensuring the success of each project, based on our many years of experience and expertise in designing buildings.
Preliminary Study/Diagnosis
We survey and analyze the characteristics of the local area, project site, business environment, similar projects, and so on. We have a network of reliable consultant and survey firms that collaborate to conduct geological and land surveys, environmental assessments, and other expert services based on our detailed specifications.
Analysis/Evaluation of Existing Buildings, Due Diligence
We conduct impartial evaluations of existing buildings, including age-related deterioration and changes in energy consumption, and economical factors such as the expected cost of future repairs.
Seismic Assessment and Evaluation
We conduct preliminary assessments in order to design appropriate seismic reinforcement. We determine seismic reinforcement policies on the basis of our assessments, and select practical reinforcement methods with holistic consideration of building uses, environmental factors, etc.
Performance Evaluation of Houses
We conduct impartial evaluations of housing performance based on legal requirements. Evaluations include 32 items in ten categories, including building safety, comfort, and others.

03Renewal and Renovation
DAIKEN SEKKEI has been honing its engineering expertise to extend the service lives of buildings; not only through design but also by enhancing their performance and property values through proper operations and management, based on life-cycle cost analysis and the adoption of energy-saving measures, IT, and other features.
We can also enhance the values of existing buildings as social assets by improving their quake resistance and/or changing their use.
Using advanced renewal/renovation techniques, we comprehensively analyze various options and possibilities to offer optimal solutions for each project.
