Construction organization design scheme submission form (form for supervision unit) (cover of Supervision approval) 2.
2.
The supervision unit shall keep one copy for its own record After the construction unit receives the scheme, it shall be kept by the documenter; note: in the process of scheme approval, any problem in any link of the company, project manager, supervisor and general supervisor will be returned to the construction site for rectification, and then rectified again, and then repeat the above approval process until all the schemes are approved.
After summarizing the drawing problems, fax them to the Design Institute, and then the supervisor, construction, construction and Design Institute jointly agree on the time and place to solve the problems found in the drawing.
The general report of foundation pit monitoring (original or copy) is the summary table of each settlement and displacement.
The complete pile is class I pile, the basically complete pile is class II pile, the incomplete pile is class III pile, and the broken pile is class IV pile.
During the joint review, our documenter will record the joint review of drawings (I) Submit it to the personnel of each unit participating in the joint review for signature.
The records (I) and (II) will be reviewed After binding, first go to the company to affix the official seal and legal person seal, and then to the supervisor, the construction unit and the design unit to affix the legal person seal and official seal.
5.
The drawings will be approved Review process: 1.
After all the seals are affixed, it will be sent to the constructor for construction.
After receiving the construction drawings, the supervision unit and the construction unit shall look at the problems existing in the drawing process, summarize the problems separately by discipline and division, and record them in the drawing joint review record (II) Then both parties exchange problems with each other and remove duplicate parts.
Young people are more open-minded to consult their predecessors on the construction site, Learning knowledge is the right way.
After being confirmed by the technical director of the project, it shall be made in n copies (at least one copy for each participating unit + the number of copies required by the construction contract) according to the actual and needs.
Pile foundation detection (integrity: small strain) If there is no class III pile in the inspection, it can be accepted.
Unit organization construction organization design (construction scheme) (form for construction unit) (company approval cover) 3.
As the saying goes: you can take the same attitude towards life as you take.
The monitoring results of the settlement of the top of the foundation pit supporting structure, the records of the settlement and floating of the foundation pit during each observation at the edge of the foundation pit (vertical direction) 4.
After the review, the supervisor shall sign the comments on the review form, affix the official seal, and return it to the construction unit.

We should also remember that we must not be careless on principles and major issues! We have summarized the construction procedures of each sub item.
Some schemes can only be approved after being demonstrated by experts.

The seal and signature procedures of each unit must be complete.
If at least half of them are called embedded, they also need to be concealed..
The basement construction process: joint review of drawings → construction scheme → commencement report → technical disclosure → earthwork excavation → cushion cap → brick formwork → pile core concrete → earthwork backfilling of bottom plate → cushion cap → waterproof layer → protective layer → cushion cap bottom plate → Exterior wall of basement negative second floor (interior wall and column of basement negative second floor) → beam and slab of basement negative first floor → exterior wall of basement negative first floor (interior wall and column of basement negative first floor) → basement roof → pouring of basement post cast strip → waterproof and protective layer of basement exterior wall → waterproof and protective layer of basement roof → drawing of basement waterproof effect drawing → basement structure detection → earthwork backfilling of basement exterior wall → retrieval of all detection reports of basement → grade evaluation of basement concrete → sub divisional acceptance of underground structure.
Core drilling sampling of cast-in-place pile (the core of the cast-in-place pile shall be extracted when the concrete is poured for 28 days) the purpose is to test the strength of the cast-in-place pile concrete and the integrity of the cast-in-place pile.
Scheme directory 4.
Portable penetration inspection record of cement mixing pile (drill about one meter deep when the mixing is completed for 3 days), which is to check the strength of cement soil.
Let’s study together! Unit project commencement report: checklist of legal construction procedures in the early stage of project construction, quality management inspection records on the construction site, and binding sequence of unit project commencement application report and construction scheme: 1.
Foundation pit monitoring: 1.
Concept of concealment: in the process of doing, some still exist permanently after completion, but those that cannot be seen need to be concealed.
3.
Text content and process of forming construction scheme: contents prepared by the project technical director Signed by the preparer and the technical director of the project, and sent to the company for review and stamped with the official seal After returning to the construction site, it shall be submitted to the project manager for review and submitted to the supervision company.
Only with excellent construction technology, good attitude and good communication ability can they stand a foothold.
The construction unit entrusts a third party to monitor at the beginning of foundation pit excavation and ends after the basement outer wall or foundation pit earthwork backfilling.
If there is class III pile, it is necessary to supplement the pile After passing the test and Issuing the test report Organize the acceptance of pile foundation.
After the joint review, take it back to the office of the project department together with the record (II) and print the record (II) again.
Anchor bolt (soil nail) tension test (on-site tension after 28 days of grouting) to detect whether its anchorage strength meets the design requirements.
