What is the work of the residential foundation investigation site?

When the survey unit enters the site, it will submit the survey plan to the construction party, that is, Party A, and then the survey party will work according to the plan after entering the site. The work content of the foundation survey site is relatively simple, roughly in the following aspects:

1.Understand the orientation of the underground pipeline, and fix the hole position after installation;

2.Arrange drilling rigs to drill, do in-situ test tests or take soil samples;

3.The second step is of course carried out at the same time as the geological inventory (professional technicians are required, and it is carried out at the same time as the drilling);

4.After drilling a few holes, it is best to roughly outline the profile of the formation on site to understand whether there are any major problems that need to be filled.

5. The site is basically completed, and the soil samples and water samples are transported back as required.

The content of the assessment survey is:

geographical location, regional conditions, soundness of surrounding infrastructure (supermarkets, vegetable markets, kindergartens, primary and secondary schools, etc.), bus routes, pollution status (noise pollution, air pollution, flood hazards); Floor, building age, wall appearance, community construction, interior decoration, room type. It's a good idea to take a few photos with a camera.

The contents of the geological and engineering survey are:

1. Select the type and material of the foundation;

2.Select the embedding depth of the foundation;

3. Determine the bearing capacity of the foundation soil;

4. Determine the size of the bottom surface of the foundation, and carry out the verification of the soft layer and the deformation of the foundation if necessary;

5. Complete the structural design of the foundation, including the calculation of the internal force and strength of the foundation and the reinforcement;

6.Draw foundation construction drawings and prepare construction instructions.

All buildings (structures) should be inspected for construction, and special construction surveys should be carried out when one of the following situations is encountered.

1.When the engineering geological conditions are complex and it is difficult to find out in the detailed exploration stage;

2.When the excavation of the foundation trench finds that the soil quality and soil structure are inconsistent with the survey data;

3.When the slope is unstable during construction, it is necessary to find out the cause and observe and deal with it;

4.During construction, the foundation soil is disturbed, and its characteristics and engineering properties need to be ascertained;

5.When further investigation data is required for foundation treatment;

6.When there are special requirements for buildings with wide skin (structure), or when new geotechnical and engineering geological problems arise during construction.

The construction survey should be arranged according to the geotechnical engineering problems that need to be solved, and the survey methods can be judged according to the specific situation, and the construction groove inspection, drilling sampling and in-situ testing can be selected.

Participant's Question] General provisions for foundation and foundation investigation work?

Answer] All buildings (structures) should be inspected for construction, and special construction surveys should be carried out when one of the following situations is encountered.

1.When the engineering geological conditions are complex and it is difficult to find out in the detailed exploration stage;

2.When the excavation of the foundation trench finds that the soil quality and soil structure are inconsistent with the survey data;

3.When the slope is unstable during construction, it is necessary to find out the cause and observe and deal with it;

4.During construction, the foundation soil is disturbed, and its characteristics and engineering properties need to be ascertained;

5.When further investigation data is required for foundation treatment;

6.When the building (structure) has special requirements for mountain drafts, or new geotechnical engineering geological problems arise during construction.

The construction survey should be arranged according to the geotechnical engineering problems that need to be solved, and the survey methods can be selected according to the specific situation, such as construction groove inspection, drilling sampling and in-situ testing.

The on-site investigation in the construction project is to have a detailed understanding of the site, electricity, water supply, transportation, and surrounding environment before construction, and to have a detailed reference for arranging machinery, temporary facilities, and construction plans.

The survey of the physical rock site is mainly to look at the following aspects:

1. The on-site traffic situation, the height of the yard, the size of the land, whether it is unconventional, and whether there is any impact on the entry and vertical transportation of the material yard;

2. On-site precipitation, required precipitation equipment;

3. Whether the surrounding buildings or places have an impact on the construction, whether measures are taken to reduce noise and prevent dust;

4. Whether temporary housing, accommodation and office space can be set up on site.

The on-site investigation of the construction project is to have a detailed understanding of the site, electricity, water supply, transportation, and surrounding environment before construction, and to have a detailed reference for arranging machinery, temporary facilities, and construction plans.

The main purpose of the survey site is to look at the following aspects:

1. The on-site traffic situation, the size of the site, whether it is unconventional, and whether it has any impact on the entry and vertical transportation of the material yard;

2. On-site precipitation, drainage and precipitation equipment that needs to be changed;

3. Whether the surrounding buildings or places have an impact on the construction, whether measures are taken to reduce noise and prevent dust;

4. Whether temporary housing, accommodation and office can be set up on site.

Construction engineering survey is a very important stage in construction, its task is to determine whether the geological conditions and natural environment of the construction project site are suitable for engineering construction, and its results provide the required engineering geological and hydrogeological data for the design and construction of a single building, and also provide various technical services for the whole process of construction.

Such as foundation scheme demonstration, engineering monitoring, etc. Engineering survey work should be undertaken by the survey unit with corresponding qualifications, and work according to certain procedures and requirements, general engineering survey can be divided into three stages according to the work requirements: feasibility study survey, preliminary survey and detailed survey.

Site survey is a bidding process that bidders must go through. In accordance with international practice, the bidder's first list is generally considered to be prepared on the basis of on-site inspection, once the first single is proposed, the bidder has no right to modify the bid, adjust the first or put forward compensation and other requirements because the site survey is not thorough, the situation is not well understood or the factors are not fully considered.

Survey site refers to the tenderer to organize the bidding applicant to the project site and the surrounding environment and other objective conditions of the on-site survey, the tenderer according to the specific situation of the bidding project, can organize the bidding applicant to survey the project site, but the tenderer shall not organize any bidder alone or separately to conduct on-site survey.

Bidders go to the site to investigate to further understand the tenderer's intentions and the surrounding environment of the site, so as to obtain useful information and make a bid or bid strategy and bidding **. The tenderer shall take the initiative to introduce the relevant situation of all construction sites to the bidding applicant. The bidding applicant shall conduct a comprehensive investigation of the site conditions that affect the construction of the project, including economic, geographical, geological, climatic, legal environment, etc.

On-site investigation is to have a detailed understanding of the site, electricity, water supply, transportation, and surrounding environment before construction, and to have a detailed reference for your own machinery, temporary facilities, and construction plans.

Survey the site on bai

Go to the site of the proposed construction project to investigate and explore the three links and one level, the surrounding environment, geological conditions, and hydrology.

and so on! Usually, the site of the bidding project is generally within the time specified in the bidding documents, and the tenderer or the bidder organizes the bidder to go to the site for investigation, or the bidder goes to the site for investigation.

Site survey is to find out the site situation before construction, compare the site situation with the construction design, find potential problems, and grasp the basic conditions of the site and the constructability of the site!

Site survey is a necessary procedure before construction, which is conducive to later construction!

Roughly agreed with the third floor. If it is a pre-construction site survey, it is to prepare for the construction of the site, mainly for the preparation of 4 passes and one level. If it is before the design, the main thing is to do geological survey, provide foundation endurance and related data for the design, etc.

1.Site surveys are.

Before construction, you have a detailed understanding of the site, electricity, water supply, transportation, and surrounding environment, and have a detailed reference for your own machinery, temporary facilities, and construction plans.

2.The bidder surveys the site mainly to see the following aspects:

1. The on-site traffic situation, the size of the site, whether it is unconventional, the need to increase the cost in this regard, and whether there is any impact on the entry and vertical transportation of the material yard.

2. The amount of on-site precipitation (if it is in the field) and the required precipitation equipment.

3. Whether the surrounding buildings or places have an impact on the construction, whether measures are taken to reduce noise and prevent dust;

4. Whether temporary housing, accommodation and office space can be set up on site.

5. If it is a fine decoration or installation project, it depends on the completion of the civil engineering, whether there is anything inconsistent with the construction drawings, such as whether the wall can bear the load and wait.

In a word, it is to fully understand the on-site situation and consider the influencing factors for the first and future construction.
