[Keywords] Civil works, supervision; foundation construction, the main construction, management points

A pre-construction preparation
Drawing Mixed 1.1 strict customs, and actively organize the construction, design, supervision of professional and technical staff together for joint hearing drawings present the shortcomings of joint trial work there is: water, electricity, Civil Engineering group after the joint hearing summary, the joint hearing between the lack of professional and construction units of construction, installation divided the total work without the technical director of the overall checks, the design unit in accordance with professional graphic design, lack of professional review. All units should arrange technical person in charge of drawing Mixed strictly on the basis of this review.

1.2 building, structure, drainage, fire drawings drawing Mixed review submissions and comment in the corresponding summary of the contents of construction plans, to avoid rework caused by the construction of missing the event.

The basis of the construction phase 2
2.1 According to the design and owners to determine the elevation of + -0.000, timely nuclear drainage, fire protection system piping elevation and whether the existing site elevation permafrost depth, so this is not for review to the drainage system caused by cold.

2.2 raft foundation, the construction of the base steel banding should be notified when the installation team for grounding device construction, review of grounding devices are correct, construction installation supervisors to co-sign it before pouring.

2.3 Prior to the basement wall formwork construction, the construction units and report to the trial selection and installation of sub-units of unit approach to avoid such as ventilation systems and construction with underground map is not marked hole, and determined the ventilation unit construction, pouring and found Ventilation openings not to allow such an embarrassing situation.

2.4 to seriously review the electrical line pipe, drainage outlets, water is the entry level consistent with the drawings and check whether it meets the requirements set casing, fixed it firmly, with the consent and installation supervision of Civil engineer consent before allowing the mold and pouring, and asked to team writing tests, to strengthen the protection of the installed nozzle.

2.5 implementation + -0.000 Mixed Slab floor system to avoid drainage, sanitary ware and building location in the plane contradiction. + -0.000 Slab drainage should be checked before pouring riser position and ventilation ducts, windows, construction of the upper beam and the perception, whether the door position sanitary ware, electrical switches, sockets contradicts the position of the switch is easy to use (with The design of the door position switch), water pipes and heating, drainage channels influence each other, so that pre-control, easy to use and beautiful to meet the principle.

2.6 Slab laying electrical wire in the tube should be with the Civil construction, electrical conduit can not be located after the banding caused by the electrical line pipe steel parts of steel protective layer and reduced cross-section force in the tube should be checked at the top of dense steel mesh set prevent the slab crack. girder bottom of the pipe laying electrical wire steel beam position can not be destroyed, if the impact of installing the electrical conduit to avoid the beam reinforcement should be laid to avoid the force structure affected.

3 of the main construction phase
3.1 floor flat in a timely manner requires the construction unit to do after the installation of a model room, bathroom, kitchen, check whether the drainage branch pipe elevation windows with Civil conflict, whether the impact of ceiling lighting and if the installation affect the use of professional conflicting functions, and timely contact design treatment.

3.2 Check electrical line pipe laying on the location of the impact of structural steel and civil construction workers on the installation of tube protection.

3.3 In the wall construction, should notify the installation of units do equipotential ground, by an electrician to do with the civil construction, to prevent the omission resulting in rework.

3.4 frame finished slab steel banding, supervision of the construction side electrical grading ring construction, the construction of correct investigation of reinforced random electrical construction workers welding practices to ensure the quality of the reinforced structure.

3.5 In line with the wall construction, electrical construction personnel should be required in the main construction steel in the ground set aside at the first column to the ground wall construction, to avoid secondary effects of construction on the structure.

3.6 In the light junction box is not checked before setting hidden location, location is not correct promptly notify the adjustment.

3.7 monitor electric wells, tube wells, front room, bathroom, kitchen, etc. nozzle hole casing set aside, and does not destroy the concrete reaches a certain strength from the time out to strengthen the construction of concrete product protection.

3.8 switch, outlet location of the households within the bias control in 5mm Check switch installation where there is not easy to use, found that super-bias and inconvenient to use, the supervisors should be able to request adjustments to eliminate the perception of defects.

3.9 The brick masonry, the requirements of the electrical junction box out of the wall 1.5 ~ 2cm, in order to ensure consistency with the decorative surface layer thickness to control perception of quality, with good electrical and civil Engineering work.

3.10 Check the fire box, the exhaust hole of the plane position size is consistent with the installation diagram, if the conflicting contact design solutions.

3.11 should prevent construction (installation) works to change the design change does not reflect the installation (civil engineering) to change the content, you should consider the impact of changes in between, to avoid construction accidents. Links to free download http://www.hi138. com
3.12 circulated to implement design changes to the system. Construction, installation personnel have read and copied at the sign design, specifying the date, source, transcripts and names of people, if the change in time to the project officers known to change the content.

4 roof construction phase
Supervision of construction with the installation of 4.1 do Gully, snorkel, airway leaving in and do the detail around the water nozzle.

4.2 Install roof lightning rod, lightning network, air barrier and other work, civil engineering should be provided with the elevation to ensure the perception of quality.

4.3 Civil Engineering fan base does not appear to be carefully installed to view maps, beams and roof water tanks set between the tank base map device are consistent.

4.4 elevator machine room roof due to electrical power lines are often well sealed and the lack of a design mark. If a similar phenomenon in the civil construction elevator machine room before the positive contact design process.

5 decoration, installation and construction phase
5.1 pairs of pipe installed up the mouth of the block system, requiring the construction in two to fill. First waterproof powder mixed with fine aggregate concrete pouring 1 / 3, etc. after the initial setting for the second pouring, to prevent water seepage.

5.2 Decoration Engineering prior to the construction of a block to clear the electrical conduit, to prevent construction of the wall decoration, on the ground as the electrical conduit closure after the rework.

5.3 Supervision of civil construction and technical personnel to install the drain line elevation to provide control to ensure proper elevation of the floor drain.

5.4 installed before construction, require the installation and civil construction and technical personnel have been installed to determine a good direction, elevation, coordinates timely review.
