Introduction


Purpose: To provide normalized instructions on the
process, item and method of the project survey; to
offer a uniform survey standard to ensure good
preparation; and to make sure the project survey
plays its due role
Contents: Process, steps, methods, and filling in
forms
Overview

Project survey:
 Ensures accurate production scheduling and timely delivery
according to contract.
 Is the original basis for data configuration and debugging of
production lines.
 Is the basis of project design.
 Is the original material for the completion report.
 Is part of normalized project management.

Conducting no project survey, or wrong project survey, will result in:
 Delay in scheduling and production, and error in data
configuration.
 Delay in delivery, with excesses, shortages and omissions.
 Project suspension and material supply delay, so that the
installation personnel can do nothing but wait, and there is no
installation solution confirmed by both parties, possibly causing
changes of customer requirements, reworking, and refusal of
acceptance.
 Lack of original materials in the completion report.
 Lack of links in normalized project management.

Every step must be carried out according to the project survey
process.
Project-related information should be collected carefully.
Project requirements, including general and key tasks, should
be understood thoroughly.
The project survey process must be strictly followed. The
survey should be scheduled and planned reasonably to ensure
high efficiency.
The survey should be conducted together with the customer to
obtain accurate original information about the site and
understand special requirements and situations.
Countermeasures should be planned to avoid emergencies
during the survey.
Every possible resource should be fully used during the survey
based on a good cooperation with the local ZTE office.
Site-related data should be measured and reorded accurately.
All sites should be designed accurately to avoid delay or
waiting due to unconformity during construction.
