NB/T 51051-2016Standard for data management of construction project in coal mine (English PDF)

Foreword

This document was issued on 5 February 2016 by the National Energy Administration of the PRC and takes effect on 1 July 2016.

It is a NB/T standard: recommended rather than compulsory, but it is the text a Chinese reviewer applies when assessing a submission.

It is classified under ICS 73.020, Chinese classification P00/09.

This standard was prepared in accordance with the requirements of the Notice of the National Energy Administration on Issuing the First Batch of Energy Sector Standard Formulation (Revision) Plans for 2013 (Guo Neng Ke Ji [2013] No. 235). Its preparation was organized by the China Coal Construction Association, and it was jointly drafted by Chongqing Juneng Construction (Group) Co., Ltd., SPIC Inner Mongolia Energy Co., Ltd., Beijing Zhuye Zhiyuan Software Development Co., Ltd. and other units concerned.

During the preparation of this standard, the drafting group carried out extensive investigation and research, conscientiously summarized many years of practical experience, and solicited the opinions of coal construction units and experts in various forms. The text was finalized after repeated discussion, study, revision and improvement, and a final review.

This standard consists of 9 chapters and 7 appendices. Its main contents include: general provisions, terms, basic requirements, classifying and numbering, data management of the construction unit, data management of the undertaking construction unit, data management of the supervision unit, collecting and arranging the engineering data, and handing over the engineering data.

This standard is under the administration of the National Energy Administration. The China Coal Construction Association is responsible for its routine management and for adjustment and modification of its partial contents, and the chief development units are responsible for the explanation of specific technical contents.

1 Scope

NB/T 51051-2016 governs the management of the construction documentation on coal industry projects in China - the records that a mine, a preparation plant or their surface works generate from the start of design to handover. It fixes what is produced, by whom, in what form, and how it is checked, collected and handed over, so that the record the operator receives is complete and trustworthy. The standard sets the general provisions and the defined terms, then the basic requirements on the responsibilities of the owner, designer, contractor and supervisor for the documents each of them produces. It covers the preparation and approval of project documentation, the forms to be used and the signatures and seals that make a record valid, the requirements on electronic files and their formats, and the production of as-built drawings. The documents are then specified category by category - basic project and approval documents, supervision records, construction management and technical records, material and equipment records, test and inspection records, construction records of each trade, acceptance records and the as-built set - with the content required in each. The collection, arrangement into files and volumes, indexing, checking and handover of the complete record close the standard. It applies across Chinese coal construction projects.

1.0.1 This standard is formulated with a view to raising the level of data management for coal construction projects, standardizing data management practice for coal construction projects, and ensuring that coal construction engineering data are authentic, complete, whole and accurate.

1.0.2 This standard is applicable to the management of engineering data for all types of coal construction projects, including new construction, reconstruction, extension and technical renovation, as well as their supporting, auxiliary and affiliated works. Other mining projects may use it for reference.

1.0.3 The construction unit, the undertaking construction unit and the supervision unit of a coal construction project, as the principal parties responsible for engineering data management, are responsible for the compilation, approval, collection, arrangement and handover of engineering data. The engineering data of the survey unit and of the design unit shall be managed by the construction unit.

1.0.4 In addition to this standard, the management of coal construction engineering data shall also comply with the current relevant national standards.

2 Terms

2.0.1 coal construction engineering data: The general term for information records in various forms produced in the course of coal project construction; referred to in this standard as engineering data.

2.0.2 coal construction engineering data management: The general term for the work of compiling, approving, collecting, arranging and handing over coal construction engineering data; referred to in this standard as engineering data management.

2.0.3 electronic records: Files stored in digital form on carriers such as hard disks, flash memory or optical discs, which are read and processed by means of electronic computers and other equipment and can be transmitted over communication networks.

2.0.4 quality control data: Records formed in the course of engineering quality control that truly reflect the quality status of the works.

2.0.5 unit construction: A work within a single construction that can be independently designed and constructed but cannot form independent production capacity or benefit.

2.0.6 single construction: A work that is set up as an independent item and that, once completed, can independently form production capacity or benefit.

2.0.7 correction: The practice of drawing a line through the erroneous content of engineering data and at the same time writing the correct content beside the erroneous content.

2.0.8 as-built drawings: Drawings that truly reflect the results of the construction of a construction project.

2.0.9 cloud line: A polyline composed of continuous circular arcs, used in as-built drawings to alert users that a certain part of the drawing has been modified.

3 Basic Requirements

3.0.1 The construction unit shall be fully responsible for the management of the engineering data of the construction project, and shall establish an archive management organization appropriate to the construction project and a sound engineering data management system.

3.0.2 The principal parties responsible for coal construction engineering data management shall establish engineering data management rules, assign full-time engineering data management personnel, and compile, approve, collect, arrange and hand over engineering data in a timely manner.
