WP should be approved by customer's Site Design Team before

CW Milestones Part-1 - Technical Site Survey from Civil works and Site Design Prospective

Technical Site Survey is an important milestone, to be achieved before land/building for Site is being leased or purchased. TSS component of a Network Rollout Turnkey Project is normally owned by Site Acquisition however a CW/SD representative is also part of TSS team. Here CW representative finalize the site and confirms as if site is initially okay from Design, Material transportation and Power availability point of view. In addition to CW representative there are normally three other departments to be represented, which include RF Planning, MW planning and Site Acquisition. It is important that

Milestones of Construction Work On Network Rollout Turnkey Project

On a GSM (or any other Telecom) site there are some activities in which Civil Works team is either fully involved or at least participated (or represented) in the activity.  Those activities in which civil works is only represented is basically the one which have ownership with other departments. But due to some sort of support work or participation is required from civil works, so it has to spare its resources for those activities.

1.       Technical Site Survey (CW+SA+RF+Transmission) (Normally owned by Site Acquisition )

2.       Work Package Approval (Process is owned by Design Department or by CW if design is totally externalized/outsourced)

3.       Site Kick off (The process is owned by Site Acquisition, however this is the activity in which site location is handed over from Site Acquisition to Civil Works, so in order to rule out the waste of money time and resources and chances of not meeting the target, at some later stage, CW representative has to take necessary measure. He/She has to mark all area which will be included in Construction, has to clearly tell site owner if any destruction is required, estimated time of construction etc.etc. )

4.       Excavation + Layout + Lean concrete (Complete CW Activity)

5.       Concrete Pouring (Pad + Columns) (Complete CW Activity)

6.       Backfilling + Top slab concreting (Complete CW Activity)

7.       Boundary wall (Complete CW Activity)

8.       Tower Erection + Accessories installation (Complete CW Activity )

9.       Generator installation & commissioning (Complete CW Activity)

10.   AC Power Inspection (Power Meter+ ACDB+ Intake box) (Complete CW Activity)

11.   Shelter or Sunshade Installation and (if applicable) Guardroom Installation (Complete CW Activity)

12.   Declaring site RFI (Ready for Installation) (Complete CW Activity, The activity is important in a sense that normally time from Kickoff to RFI is an important KPI among other indicators. This is because during this time only civil works department can do work on site and  is considered one of the main bottle necks in such projects. Once the site is declared RFI other teams of project like Telecom Implementation, BSS, Care can also do their due work on site along with other minor civil works which are being carried out on site. )

13.   Finishing Works (Complete CW Activity)

14.   Red – Line/As – Built Drawings preparation (Complete CW Activity)

15.   Acceptance from Customer (The activity is owned by project as a whole)

Applicable Health and Safety(HSE) Documents on Telecom Projects

The previously mentioned HES guidelines have normally been enforced by either a Client or vendor (or sometimes by both). And have to be followed in general by all vendors and its Partners’ employees. However if this would not be the case, the  each person who is involved in decision making and implementation, either as manager or junior engineer or worker or supervisor at the site have to follow all possible guide lines. In addition to these, project specific documents related to HES will also be applied after getting approval from Project Director. The following documents may normally be applicable, and are vital part of Partial/Final Acceptance Documents folder.

•  HES Checklists
•  HES Handbook
•  Incident-Near miss Report
• Risk Assessment Forms

In order to ensure that a fair deal of HSE compliance is on work, a vendor would have to conduct various audits and visits in order to verify that all its local and global conditions are being followed by its Partners during work on sites and/or at factories.

HSE Checks Related to Telecom Implementation

Although principally Telecom Implementation does not come under the domain of Civil Works Department of a telecom company (either vendor or client or operator), however working in telecommunication industry really demands muti – functional and cross – functional skills to have, demonstrate and at times even to practice. So therefore it is good to know at least some basics of other functions/departments you are working with in project. And some telecom organizations have even trained their staff for cross – functional training to utilize the same work force to work on different type of assignments even out of their main area of expertise.  (I am planning to cover this topic of x-functional training in detail in some other post later).

So in view of above details, now I think you be more interested in following some HSE Checks related to TI.

1. TI Equipment transportation should be carried out keeping in view the safety aspects so that risk of injury could be avoided.
2. Trained Riggers are required with proper Ropes & Pulleys to pull Feeders and Antenna Dish movement above tower.
3. Correct Polarities to be used while Installation of Power system/battery. Wires with proper Gauge are required. 
4. Anti Static Strip Should be used by personnel, plugging in modules. 
5. Proper coring & mid spanner Stripper Tool Is required for making on site connectors.

Safety measures for the Antennas Mounted at the Edge of the Rooftop (on Monopole or RT Tower)

1.         Poles less than 5m height will be equipped with step irons or a removable ladder system. Some form of attachment point for safety belt/harness will be installed.

2.         Poles higher than 5m are to be considered masts or towers and the standard recommendations as required during erection of towers needs to be applied, as mentioned below

i)          Lightening arrestor to be installed on legs adjacent to ones where BTS equipment is placed.

ii)        Fall arresting system (a system for the safety of workmen who are climbing the tower) must be properly installed.

iii)       Rest platforms must be installed at the specified heights as mentioned tower’s assembly/erection drawings

iv)       All the tower bolts must conform to the allowable torque limits as recommended by tower designer

v)         Torque test would be applied after finishing of tower erection by sub-contracting company in front of vendor’s Site Engineer (CW representative)

Protective and Safety Measures for Accessing Rooftop Structure Wall Mounted Antennas

Sometimes as per requirement by RF, height of antennas to be installed is such that they need to be installed on the walls of available structures. Care must be taken for fixing mounting poles have to be installed such that no permanent damage is being made to existing structures.

1.    Fixation of anchors has to be made on RCC (either on column or on slabs), must not be on brick/blocks  

2.    Access can usually be handled safely with a portable ladder if there is no inherent fall risk.

3.    If there is a potential fall risk, a permanent ladder with safety system will be installed.

4.    Working in a two-person team is a general rule of thumb whereby one worker can support the ladder of access for another worker.

5.    The ladder has to be of good quality according to local requirements.
