Iron wire, covered electrode, sleeve (connecting sleeve), steel pad or other materials used for fixing steel bars, as well as rust prevention, interception, wire wrapping, welding, bending, operation loss, on-site transportation (including secondary handling) and installation of steel bars, are all ancillary works of tunnel engineering, and will not be measured separately. At the same time, the number of steel bars increased due to lap joint or construction connection shall not be measured. Processing, installation and hoisting equipment shall be provided and undertaken by Party B. ..

3. The installation and disassembly of templates and supports used in this project, the production and use of internal models, the release agent and underground maintenance treatment (except the material cost) and other related expenses have been included in the contract project unit price, and will not be measured and paid separately.

4. Excavation and cleaning of foundation pit, transportation and spoil of residual soil, waterproof and drainage, foundation treatment, etc. Accessory works belonging to related projects shall not be measured and paid separately.

5. The processing and installation of embedded parts are ancillary works of tunnel engineering, and are not measured separately.

6. The contract unit price does not include all the electricity charges consumed by the project construction.

7. The machines and tools used in this project are solved by Party B itself, and their scheduling, use, maintenance and safety inspection are subsidiary works of related projects and are not measured separately.

8. The unit price of this contract does not include tax, and the tax shall be paid by Party A. The tax of this project only refers to business tax, urban maintenance and construction tax and education surcharge, and other taxes shall be borne by Party B. ..

9. Matters not covered in this description shall be subject to the technical specifications of "Model Domestic Bidding Document for Highway Engineering of People's Republic of China (PRC) Ministry of Communications (2003 Edition)", and further supplements and modifications shall be made.

Article 4 Quality standards

The engineering quality standard is: excellent grade, and the evaluation standard is based on the water conservancy construction standard.

Specific construction requirements are as follows:

(1) Party B must carefully organize the construction, strengthen internal management, strengthen personnel education, strictly control the quality of the project, ensure the progress of the project, and complete the repair of the contract project and its defects on time according to the construction technical specifications adopted by the project and the construction drawings and technical disclosure provided by Party A. ..

(2) During the construction period, Party A shall organize the acceptance according to the quality standards in the contract signed with the owner. If the quality is not up to standard, Party B must rework and repair, and the cost loss shall be borne by Party B. If the quality of the project is poor and cannot be saved, Party B shall bear all losses and expenses, including all economic losses such as the owner's quality fine or punishment and Party A's reputation loss, and the construction period will not be postponed.

(III) Inspection procedures in the construction process: Party B must carefully conduct self-inspection, and report to the on-site technical director of Party A for inspection after passing the inspection, and report to the supervision engineer after passing the inspection. Only after passing the test can the next working procedure be started. During the construction process, Party A's inspection or signature of the project cannot exempt Party B from the final quality and responsibility of the project.

(3) The specifications, binding, connection, welding and arrangement of steel bars shall conform to the technical specifications and construction drawings, and shall not be changed without authorization.

(4) The formwork used must meet Party A's requirements or appropriate specifications, and the roof arch shall be of fixed specifications. The surface should be flat, smooth and free of rust spots, and the structural dimensions should be standardized to meet the construction design requirements. Before pouring concrete, strictly check the position and model of steel bars to ensure that the concrete has enough protective layer thickness, elevation and structural size are accurate.

(5) The exposed surface of the cast concrete structure shall be smooth and straight, free of scale, honeycomb, pits and cracks, and there shall be no cracks at the construction joints. Otherwise, Party A will be punished according to 30 yuan/m2. At the same time, Party B shall be unconditionally responsible for the repair or rework, and its expenses shall be borne by itself.

(6) Concealed works shall not be covered or buried at will without self-inspection and on-site supervision engineer's inspection. Party B shall ensure that the quality inspectors and supervision engineers of Party A inspect and measure the projects to be covered or buried, especially before any part of the foundation is built, the foundation can only be concealed after inspection. Otherwise, Party B will rework itself and bear the relevant expenses.

(7) The structure shall meet the geometric dimensions specified in the design drawings, so as to achieve inner reality and outer beauty, and strengthen maintenance and protection to ensure the quality of concrete construction.

(eight) the installation of the template should be flat, straight, stable and firm, and can completely resist the violent vibration and collision in the construction process; Staggered platforms must meet the requirements of technical specifications, the release agent specified by Party A must be carefully daubed, and the dirt and sundries in the formwork must be removed before pouring concrete; Safety protection should be done when dismantling or moving the formwork. Otherwise, the resulting safety and quality defects shall be borne by Party B. The inspection and signature of Party A's personnel cannot exempt Party B from the responsibility for the quality of this project.

(9) Before installation, the bracket must be checked; The underground should be compacted to ensure sufficient strength, and the installed bracket should have sufficient stability and firmness to completely resist the construction load, violent vibration and collision during the construction. Safety protection shall be done during demolition, otherwise Party B shall be responsible for the resulting insecurity and quality defects. The inspection and signature of Party A's personnel cannot exempt Party B from the responsibility for the quality of this project.

The quality objectives of this project require:

The qualified rate of all partial projects 100%, the excellent rate must reach over 95%, and the unit project quality is excellent. For every reduction of 1%, Party A will deduct 1% of the project cost, with a maximum deduction of 10%. The evaluation results shall be subject to the results signed by the supervision engineer.

If the appearance quality of the tunnel can't meet the requirements of the owner, it should be abandoned and rebuilt resolutely, and all losses caused thereby shall be borne by Party B. ..

Article 5 Material supply

(1) Information provided by Party A:

1. Party A will only provide steel bars, binding wires, cement and gravel to be transported out of the hole, and Party B will solve the rest by itself. Party B shall be responsible for the installation, dredging, cleaning and dismantling of the concrete pumping pipeline, and the expenses shall be borne by itself.
