Large-scale commercial projects fine decoration project 14 control points, quickly master the core control system

The following is a large shopping mall project “control points” to do the key explanation.

Arc corner aluminum plate closing model

Key points of closing control at the bottom of the fire curtain:

1, the curtain handed over fine decoration, must be adjusted to the design height and bottom leveling;

2, fine decoration steel frame and spring production completed, waiting for the curtain professional fire acceptance before the final commissioning and then install aluminum plate;

3, the strength of the spring must be focused on control;

Roll curtain track interior finish by fine decoration, due to the roll curtain when swinging larger, the finish should be at least 1cm from the edge of the curtain steel splint, to avoid the curtain operation deviation caused by the middle decoration surface being destroyed.

About Roll Selection:

In the case of cost and fire requirements, steel side curtains can be selected during the rolling curtain bidding phase.

Natural stone quality control

Toilets, elevator hall walls, ground use more natural stone, natural stone quality control has become the focus, large quantity, high quality, to ensure the stable supply of stone:

1, first of all, should determine the amount of all kinds of stone demand (this quantity is often very large, need more than stone factory supply at the same time to ensure a stable supply);

2, to find and select several stone suppliers, to prevent the same variety of stone, appear too large color difference, pattern changes, the same variety of stone should be provided by the same stone supplier;

3, stone processing plant should try to choose near the project site, to shorten the transport time of finished stone, reduce the risk of damage in the transport process;

The ground-based artificial stone paving process

Semi-dry mortar paving

Advantages:

Construction is convenient, fast placement speed, the grass-roots flatness requirements are small, the construction difficulty is small, relies on semi-dry mortar to find flat, workers easy to master, stone back with a pasting agent is relatively small, relatively low cost.

Weaknesses:

Because the construction is convenient, water analysis is slow, easy to produce black seams, return alkali, grass-roots is not easy to produce empty drum cracking and other common diseases, for often access to spider cars, equipment, the first layer, pressure strength is weak, stone easy to break;

Thin-paved method

Advantages:

As long as the cushion concrete reaches the 45-day maintenance period, then use 5 to 8mm thick special paste to find a flat. Moisture in the mat layer will not affect the stone, can effectively avoid stone black seams, return tide and other common quality problems, strength is better;

Weaknesses:

The maintenance period of the mat layer is long, the concrete mat layer needs to be constructed in advance, and the flatness of the basic mat layer is high; Not suitable for projects with tight schedules;

Bathroom control points

Key points of control:

1, many operations, progress control is the first point;

2, simplify the handover process, ground opening into the fine decoration sub-contract;

3, wall floor tiles strict seam, mechanical and electrical points, ware and other installation with wall tiles to find relations;

4, the lower plate area set secondary leakage, do find the flat layer to the ground leakage to find slope;

5, waterproof construction should be done to the outlet above;

6, switch valve set inspection port, no clean-up dead end;

7, wall yang angle, step yang angle collision resistance;

8, the selection of non-slip floor tiles; construction using special adhesives to prevent wall tiles empty drum, falling off;

9, the ground leakage drainage is smooth, no leakage;

Efficient implementation – progress assurance

Fine decoration and mechanical and electrical professional transfer process

On-site coordination process:

The electrical and mechanical professional will be in charge of road installation completed→→ hardcover repair professional according to the owner signed the comprehensive smallpox map site partition positioning →→ handed over mechanical and electrical professional end installation, and after the crackdown, closed will sign →→ hand over hardcover repair professional On-site re-examination receiving →→ hardcover repair professional to complete the seal plate →→ mechanical and electrical professional final point debugging.

Medium vertical transport

Renovation of bulk material vertical transport has become a difficult problem, according to the actual conditions on the site, in the atrium scaffolding set aside 5m x 4m upper port, and set up an electric lifting device to improve vertical transport efficiency.

03.

Atrium scaffolding coordinated management

Oval atrium, corridor area scaffolding up to 40.5m, the use of units have glass barrier security, mechanical and electrical, escalator sealing, sun blinds, ceiling hooks and other units, the use of at least 3 months, to the first floor of the ground reserved for a short laying time. Scaffolding and removal and professional cooperation will have an impact on the duration.

Ensuring that the construction content on the scaffolding is completed as planned is the focus of coordinated management:

1, to ensure that the river and escalator materials are on scheduled arrival and installation;

2, other related professional work on the shelf completed on schedule;

3, scaffolding works easy to rip affect the progress, it is recommended to divide into the total package contract.

04.

Fire acceptance

The requirements for fine decoration for the formation of fire-resistant partition, shop glass partition installation completed, atrium scaffolding removal, smoke wall installation completed, smallpox sealing board, and so on.

To ensure that the above work is completed on schedule to be a smooth fire acceptance, should focus on the control of the following content:

1, improve the efficiency of the transfer of work with the mechanical and electrical professional return, to ensure that smallpox by the planning node smooth seal board;

2, follow up the barricades, smoke wall, shop glass, fire doors, and other materials orders and entry.

Lean management — collaborative management

01.

The stages are coordinated

Bidding phase:

• To assist the owners in preparing the technical specifications and management requirements of the tender documents;
• Review the tender blueprint, for not meeting the specification office timely put forward;
• To the standard segment division to the owners to rationalize the proposal, the site construction is prone to problems in the link to propose solutions.

Deepen the design, material sealing phase:

• Deepening design by the owner design department head, to assist the owner to deepen the design progress and quality management;
• To confirm the material sealing work and the entry acceptance process;
• The subcontracting is submitted to the surface material model audit, and the quality standard model is put forward for reference;
• Check the fine decoration drawings and masonry, mechanical and electrical drawings conflict and submit to the owner to resolve.

Construction phase:

• According to the characteristics of the project, the selection of the construction model area is proposed.
• Confirm the construction scope of fine decoration and rough decoration, and confirm the practice of rough decoration;
• Logistics area points unified determination, strict control brick seams and point arrangement;
  
• In advance, the location of fire hydrants and the direction of fire door opening are raised, so as to reduce the delay of fire acceptance.

Transfer of property, maintenance phase :

• Cooperate with the business management to urge tenants to enter the site for site handover, rectification;
• Handle repair incidents that occur on site.

02.

Cooperate with the owner

In the basement bathroom before the start of masonry to check the fine decoration tender map, found that the masonry drawings do not match and timely put forward.

03.

Deepen design management

Organize drawing questions and check for site design omissions.

04.

Large tenants come in to work together

Tenants into the site decoration, the public area of the site management are more important, decoration package to the tenant’s management can only be coordinated through the business management company, on-site implementation is not strong, tenant decoration garbage, materials and other large accumulation in the public area, the civilized construction of the public area have a certain impact, many times the coordination of the management company is not effective, can only let the subcontracting of the front glass door closed, played a certain effect.
