CONDITION ASSESSMENT OF A GRIENFIELD TOWER

Quality Assessment of a Greenfield Telecommunication Tower

A collapse in tall greenfield steel tower used in telecommunication or transmission work will result a serious damage to the nearby properties or people. Hence it is essential to monitor the quality of the towers periodically.

In a quality check the assessors have to asses the quality of foundation for any decay or settlements, quality of the steel members and the connections, quality of earthing of tower, quality of the equipment mounted, etc.

Sample assessment report on the verticality and the quality of foundation is shown below.

MOCK UP TEST FOR LARGE CONCRETE POURS - TEMPERATURE MONITORING

Mass concrete is defined as "any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from hydration of cement and attendant volume change to minimize cracking." [ ( ACI Committee 207–Mass and Thermally Controlled Concrete ) Mass concreting can result in high temperatures in concrete core during hydration process. Which can result thermal cracking of concrete in a severe way. Basically the temperature variance (in different locations of the concreted element) or the temperature gradient will cause the thermal cracking.

BORED AND CAST IN SITU PILES

Bored and cast in-situ piles or bored & cast in place piles carries the process of installation in the name it self. A bored and cast in-situ pile is installed by boring the soil and or rock using heavy machinery and pouring concrete to the bored hole with or without steel reinforcement. Figure: Rotary drilling machines in the process of pile boring You can watch the detailed process in video form the following link https://www.youtube.com/watch?v=u6YGxSzvmKo You can check more details from the following link MOS for Bored Cast In situ Pile Installation https://engcivilstuff.blogspot.com/2020/03/bored-piling-installation-by-rotary.html

BOQ FOR A GRIENFIELD TELECOMMUNICATION TOWER CONSTRUCTION

Bill of Quantities for a Tower Construction A BOQ for a telecommunication tower use for Civil Engineering works is shown in figures below. Normally in a construction of a telecommunication tower, the Civil work contractor has to undertake site clearance, access road preparation, fencing, plinths for other equipment like BTU or generators, Meter compartments if any, Foundation of tower, etc. and the installation of tower by using Rigger teams.
