How about bulk hardcover repair? Look at the late-night summary of the front-line project manager, and you’re more confident about doing a good job
In order to improve the quality of decoration projects in an all-around way, effectively carry out cost control, standardize the refined decoration management process, reduce the rate of repair, improve the competitiveness of the company’s products, we must strengthen the hardcover repair project management and control points.
The general idea is
– 5 key nodes in the project control process –
01
Summary of the heavy difficulty analysis
1.1
Difficult analysis
Anti-cracking measures for walls:
Anti-aircraft drum:
(1) Before the construction, check the original wall for empty drums, shedding and other hidden dangers must not blindly start work;
(2) To prevent the glass brick empty drum and shedding, the glass brick before the paving of its full back glue treatment, so the back glue process is particularly important, focus on inspection (inspection focus: back glue to the edge uniform not exposed bottom), construction using special tile adhesive construction.
Floor tile paving process requirements:
(1) Kitchen and bathroom floor elevation and indoor elevation must meet the design requirements, and the ground should be cleaned.
(2) Tile pattern is consistent, with no scratches, color differences, cracks, pollution, missing angle, and other phenomena.
(3) Before laying the tiles, the drawing must be deeply typographed to determine the loss.
Leak-proof:
Waterproofing process requirements:
(1) Grassroots clean-up; floating dust, mud blocks, impurities around pipe walls, etc.
(2) The angle needs to be done after arc treatment, water does not leak to block.
(3) New and old walls sewn wire mesh.
Waterproof control point:
(1) The threshold is waterproof with a water-stopping band brush, waterproofing should be brushed to the dry area (walkway) and turned up 30mm.
(2) The ground leakage position is treated as a funnel.
(3) Shower room water belt.

Cost control
2.1
Cost management
Develop a project control dynamic table:
(1) The lack of understanding of the process led to measurement errors, this work must have construction staff, budget staff, with shifts combined with the base drawings to participate in the calculation, and let the class sign confirmation.
(2) In the process, the budgeter and the construction staff should check, check and adjust the number of early warning lines in time for the site practice.
(3) For the characteristics of household type unified, batch operation, the basic materials need to be fixed-scale processing, reduce loss, but pay attention to the bottom and unified ingredients, inspection, avoid long cut into short, short throw away phenomenon.
Warehouse management: before entering the project, we need to check the project location (busy areas, suburban areas, surrounding facilities, etc.), affecting the transportation of materials, personnel accommodation, etc.

Prepare in advance
1.1
Construction deployment
On-site roads and the surrounding environment: construction can not affect the surrounding greening, not far from the residents of the construction pay attention to production noise, transportation.
Vertical transport: hardcover entry, the construction elevator has been removed, the indoor formal elevator has completed acceptance, hardcover units to do elevator car finished product protection, by the hardcover unit sent a person to open the elevator, as a vertical transport tool.
Construction organization: According to the actual situation on the site to prepare a practical construction organization design.
Coordinated management: coordination with construction units, supervision units, total package units, design units.
Bottom-of-the-deal learning: tender bottom, cost bottom, contract bottom, construction technology bottom, construction interface bottom, safety bottom, safety education and training, process training, and learning.

Line reviews
Construction line:
Step 1: The main control line, axis, finish surface control line (wheelbase minus 1m), the top surface around the wall is completed facing up to 250mm for the electromechanical elevation line, the ground 0.000 horizontal lines, each layer 1-meter horizontal line, line for the first step.
Step 2: The main control line of the total floor plan of each layer, the axis, the completion surface control line (wheelbase minus 1m), the top surface around the wall is completed facing up to 250mm for the electromechanical elevation line, the ground 0.000 horizontal lines, each layer 1-meter horizontal line, for the second step.
Step 3: According to the results of the straw line, for deepening After the designer partially adjusts the floor plan, but the modeling line, called the third step line.
Step 4: Take the middle control line of the walkway as the baseline, adjust the wall inside and outside the door cover related to the walkway to complete the face line fixed door cover, this line method is called the parallel line method for the fourth step line, also called the walkway construction method in the construction, the door cover finished construction method.
Step 5: In the production process, some of the original positioning lines will be covered by construction work, at this time the construction unit according to the original size in the same position re-placing lines, so-called the fifth step of the line, also known as the second line.
To ensure dimensional accuracy, on-site elevation control dimensions, are provided by us with the one-meter line, control line.
Detection method: carpet measurement using a two-meter ruler, at least cross-measuring at the same position, if a gap greater than 3mm or even 5mm appears under the ruler, indicating uneven ground.
Sensors, showerheads and lamps must not be less than 300mm apart
Line management:
1, construction points: construction personnel in the construction, by the construction technical personnel on-site technical bottom, according to the construction blueprint design drawings with ink line ejected grass-roots, complete the surface line, by the project construction technical person in charge of the survey, before the construction, all dimensions of accuracy to the construction blueprint drawing design documents.
