Although the balance between mitigation and adaptation strategies is still considered internationally and nationally in different sectors, it shows some important connections at the project level in the construction sector. The IPCC TAR concluded that adequate optimization between mitigation and adaptation will be a long and tedious process and the optimal mix of response options will vary by time and country (place) as local conditions and costs vary ( Richard JT Klein et al., 2003). Some central shortcomings in optimizing mitigation and adaptation strategies at the project level are, namely, uncertainty, regardless of the diversity of economic values ​​and preferences within and between societies, fairness or fairness for the distribution costs of impacts (burden sharing), local conditions. Richard JT Klein et al. (2003) state that in the absence of perfect information, a number of alternative combinations of mitigation adaptation and mitigation strategies can be proposed that differ in their economic, social and environmental impacts. For example, although one option may be fair and environmentally friendly, it may be economically advantageous compared to other options, although less environmentally and socially acceptable. These authors present themselves to identify which mix or mixes of options are justifiable, it is necessary to design a multi-criteria framework with which it is possible to capture, quantify and compare the direct and dependent effects of the application of each of these or other possible criteria. Other scholars such as Freccia et al. (1996) and Toth et al. (2001) argue that balancing mitigation and adaptation will be difficult due to some unique characteristic issues such as long-term time horizons; non-linear and irreversible effects; social economic; geographic differences a...... middle of paper ......d risk: implications for insurance and risk transfer.
