A good plan is a good start for everything. Green construction planning should adapt to local conditions, closely combine the construction site and engineering characteristics, and implement energy saving, material saving and environmental protection in every corner of the construction site and every detail of the construction process. Avoid one step at a time, and put an end to covering up process defects by grabbing progress.
First of all, organize employees to carry out training and study on green construction management regulations, improve employees' awareness of green construction, and make employees fully grasp every regulation of green construction. Establish a green construction management system with the project manager as the leader, achieve clear goals, and form a good start for everyone to have something to do and everything to do.
Secondly, brainstorm, according to the actual situation of the construction site, with the principles of land saving, energy saving, water saving, material saving and environmental protection, carefully plan and prepare the green construction scheme, and use advanced technical measures and management to save resources to the maximum extent, improve resource utilization and reduce the adverse impact of construction on the environment.
Thirdly, establish the green construction project management system, establish and improve the green construction management data files, and carry out green construction inspections regularly, with clear inspection records. Hold regular meetings on green construction management to sum up experience and promote implementation. At the same time, green construction, civilized construction and safe construction must be deployed.
Second, funds are in place.
If green construction is regarded as a product, there will inevitably be manufacturing costs, and the investment of funds is also the guarantee condition for doing a good job in green construction, and earmarking funds can well ensure the orderly implementation of the green construction plan.
Green construction funds are led by the contract department, and other relevant departments are organized to calculate the amount of green construction funds according to the green construction plan, and form specific details, which will be distributed in place with the construction progress and green construction.
