Quality commitment letter

With the development of society step by step, the commitment letter appears in our field of vision more and more frequently, and it is completely voluntary. You didn't even know when you wrote the letter of commitment? The following are eight quality promises that I have carefully arranged. Welcome to share.

Quality Commitment Article 65438 +0 xx residential community project is located at the intersection of xxxx extension line and xxxx*, which consists of * * floor residential buildings and * * floor residential buildings, and there is no basement.

The total construction area of 1-9# building is xxxx㎡, which is a shear wall structure, and the engineering design purpose is residence. 1 is a frame structure.

External wall thermal insulation material: the first layer is 65 thick reinforced rock wool board. 2- The top floor is made of 80-thick molded polystyrene insulation board (combustion performance B 1 grade). Each batch of materials was sampled and sent for inspection under the witness of the supervisor, and all the results of the second interview were qualified. Meet the design and specification requirements.

Supervision unit (signature): MM DD YY.

Employer (signature): year month day.

Extended reading: common causes of problems in external wall insulation layer;

1, material factors. The density of insulation board for external wall insulation should be 18~22kg/m3, and some construction units will use insulation boards below 18kg/m3, which is not enough and will easily lead to cracking of plastering mortar layer; The natural shrinkage time of insulation board in natural environment is as long as 60 days. Due to factors such as capital turnover and cost control of production enterprises, insulation boards that have aged less than seven days have been put on the wall. As a result, the insulation board continues to shrink after being put on the wall, and the plastering mortar layer adhered to the insulation board cracks.

2. Building technology. The roughness of the base surface is too large, and the adjustment methods such as adhesive layer thickness, multilayer board and surface polishing will lead to defects in insulation quality; Dust, particles and other substances on the surface of the base layer that hinder adhesion are not treated at the interface; The bonding area of insulation board is too small, which does not conform to the specification and can not meet the quality requirements of bonding area; When the rice mortar layer is exposed to the sun or constructed in high temperature weather, the surface layer loses water too quickly, resulting in cracks;

3. Temperature difference change. The thermal conductivity of expanded polystyrene board and anti-crack mortar is different. The thermal conductivity of expanded polystyrene board is 0.042 w/(m k), and that of anti-crack mortar is 0.93 w/(m k), with a difference of 22 times. In summer, when the sun shines directly on the surface of plastering mortar, the surface temperature of plastering mortar can reach 50~70℃, and in case of sudden rain, it will drop to about 15℃, with a temperature difference of 35~55℃. This temperature difference, as well as the influence of day-night temperature difference and seasonal temperature, lead to great differences in the deformation of plastering mortar layer, which is prone to cracks.

Quality Commitment Chapter II Company:

Our company solemnly promises to abide by the following clauses in the process of participating in the procurement activities of * * * * * centralized procurement products:

1. The products provided by our company meet the national or industrial product quality and technical standards, meet the product quality standards agreed in the contract, and have the technical performance that the products should have.

2. The products provided by our company meet the national or industrial standards for protecting human health and personal property safety.

3. If the products provided by our company are restricted products, the production date, safe use period or expiration date can be clearly marked in a prominent position.

4. If the products provided by our company have quality problems, our company will send relevant personnel to repair them within the time stipulated in your company's contract, and replace and install them free of charge within the time limit required by the state or promised by our company. If there are serious quality problems, we will return them.

5. Be honest and trustworthy, and do not forge or fraudulently use quality marks such as certification marks. No adulteration, no counterfeiting, no shoddy, and no passing off unqualified products as qualified products. In case of violation of the above commitments, our company agrees to take measures such as investigating our company's liability for breach of contract, rejecting our company's supply and canceling our cooperation qualification in accordance with the contract. If any personal and property losses are caused to your company or a third party due to the quality problems of the products provided by our company, our company will be liable for compensation.

Article 3 of the Quality Commitment Letter: This Commitment Letter is formulated in accordance with the relevant national regulations and standards in order to strengthen the management of raw materials entering the site, strengthen quality monitoring, improve the code of conduct for the use of materials and ensure the quality of the project:

1. Raw materials used in the construction site, such as steel bars, cement, pebbles, sand and additives used in structural concrete, must be sampled and sent to the testing center for re-inspection before they can be used.

2. When sampling, three parties (owner, supervisor and construction team personnel) must sample and send samples for testing at the same time.

3. If the above-mentioned raw materials that must be reinspected are used without reinspection, the company will be fined at least 20xx yuan for each discovery. And suspend the construction, re-inspection qualified rear can return to work.

4. Materials must be inspected and rechecked before use. For example, in actual construction, other types and specifications of materials are shoddy or used at will. Once found, the company will be ordered to replace the same raw materials and semi-finished products as the original samples, and will also be fined 1% ~ 2% of the partial cost.

5. If unqualified materials, semi-finished products and equipment are found to cause engineering defects and accidents, the company will be fined more than 20xx yuan 10000 yuan.

Remember this, don't have any leisure addiction!

Please rest assured the leaders of your unit!
