Around the construction site 100% enclosure;

Material stacking 100% coverage;

100% in and out of the vehicle washing;

Site ground 100% hardening;

Demolition site 100% wet operation;

100% muck vehicles are transported in a closed manner.

Two: six in place:

Fully automatic washing equipment is installed and used in place; ?

Construction waste transport vehicles are sealed in place;

When the site is demolished, professional dust suppression facilities shall be used for wet operation.

A construction site is a place where construction projects are developed and civil engineering is carried out. Its scope is often closed by coaming, barbed wire or fence, which restricts the entry and exit of personnel, materials, machinery and vehicles. Guarded by the property manager. You may need to register your identity and wear a helmet when entering or leaving.

Design change and engineering visa work are very important in construction management, because it involves a wide range of contents, complicated reasons and poor regularity, and it takes a long time to determine its cost.

Generally, the project cost adjusted due to design change and project visa accounts for nearly 20% of the total settlement of unit project completion, ranging from 6%, especially in technical transformation and technical measures, accounting for more than 20%, and sometimes even reaching 40%.

Therefore, it is a great event for the construction unit to attach importance to and do this work well. I think it is the first important thing to know and understand the meaning and content of design change and engineering visa, so as not to help.
