feasibility and economic rationality for better quality construction. 

Design flow: 

1 Determine design purpose and design plan: determine the requirements 

and coverage target of a respective works based on the technical 
bidding documents of construction unit. Plan the scale of current works 
and design, determine the design contents and estimation plan after 
careful study of the reconnaissance and technical bidding documents. 

2 Formulate general frame of the plan: formulate general frame for design 

plan and determine the design direction based on the design plan and 
requirements for current works. 

3 Perfect designing contents; complete all the contents of the plan, such as 

design basis, panorama data analysis based on reconnaissance 
report. 

4 Analysis on feasibility and rationality of the plan: all plans must be 

analyzed in terms of technical feasibility and rationality such as 
prediction on the border magnetic field, switch analysis, interference 
analysis, balance analysis and so on. 

5 Quotation; rationally quote on the plan according to the market 

requirements after repeated examination of the feasibility of technical 
plan and verify the pricing of the plan after comparison. 

Key requirements for design:

 

1 Reinforce the analysis on the rationality of the plan 
2 Decide reasonable editing format and corresponding fonts according to 

the template of the design. 

3 Reinforce the analysis on pilot panorama testing. 
4 Use special drawing tools (Microsoft Visio) to draw the point location 

drawings and system frame. 

5 Hand signature shall be requested for places of signature. 

 

5.1.3 Organization of Construction

 

Purpose:

 according to statistics, the start or poor effect at the start of 

system after the completion of construction is usually caused by disorder in 
construction and management. Therefore, apart from strict execution 
according to the process provided in relevant documents, specific plan for 
construction of works must be formulated in light specific construction to 
strictly provide all flows, reinforce the management of site construction and 
practice liability system of each work for each individual. 

Organization structure
