Overview

Project survey is the initial stage of the whole project.

“Well begun is half done.” It has direct influence on every link of the project

afterwards. 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.

strong vibration or noise, and high-voltage electrical equipment The equipment room must be built at the location that meet the engineering

design requirements of the communication equipment. A long-term view should be taken before construction. Do not relocate the equipment room unless necessary. Durability should be considered to avoid frequent renovations. The equipment room must be fireproof and shockproof.

Construction, structure, heating, ventilation, power supply, lighting and fire protection are required.

MPT specifications must be followed. The equipment room should be designed for the convenience of the cabling

and daily maintenance of the signal cable and power cable, to reduce cabling cost and communcation failure and improve working efficiency.

General Information of Equipment Room Location of equipment room Type of equipment room Route for equipment to enter the equipment room Equipment unloading area

Temperature, Humidity and Daylighting of Equipment Room Short-term working condition (temperature): -5C~+55C. A

temperature between +15 ~+30 is always ℃ ℃recommended.

Short-term working condition (humidity): 20%~90%. A humidity between 40~65 is always recommended.

Direct sunlight should be avoided. There should be no glare. Generally, the equipment room is lighted by fluorescence lamps. For an equipment room where a power failure frequently occurs, an emergency light should be installed at a proper location.

Survey Description: Generally, Node-B equipment rooms are unattended, so

fluorescence lamps are used for lighting.

Indoor Environment Survey Equipment Room Floor and Fire Protection

The bearing capacity of the equipment room floor should be higher than 450kg/m2.

The equipment room must be equipped with appropriate fire fighting devices, such as several dry powder fire extinguishers.

Antistatic raised floorboards or antistatic terrazzo should be laid in the equipment room. Conductive floorboards should be used instead if raised floorboards are unavailable. Static grounding must be performed for conductive or raised floorboards, which should be connected to a grounding device through a current-limiting resistor and a connecting wire.The resistance of the current-limiting resistor should be 1MΩ.

Survey Description: If antistatic floorboards are used in the equipment room, the floor height should

– Where:– Q1 is the head radiation of the equipment.– V is the DC power supply voltage (V).– A is the average power consumption current (A).– The value 0.82 is the product of 0.86 (the scaling factor for converting every

watt of electrical energy into heat energy) and 0.95 (the scaling factor for converting electrical energy to heat energy in the equipment room).

2. The refrigerating output of the equipment room: Q2=S×150 (kcal/h)– Q2: The refrigerating output of the switching room– S: The area of the switching room (M2)– 150: The parameter for converting room area to refrigerating output

(Kcal/h×M2） 3. The refrigerating output of the air conditioning (actual capacity): Q=Q1+Q2

Survey Description: Different models of equipment has different requirements on ambient temperature and

humidity. For detailed information, refer to the corresponding equipment technical manuals. Generally, it is required to install an air conditioning system in the equipment room. If an air conditioning system exists, the power of the air conditioning and the heat radiation of the existing equipment should be noted during survey. If the existing air conditioning system cannot meet the requirements of the new equipment, additional air conditioners are required. The air conditioners should run automatically once powered.
