PROX5 Feasibility Project

telecommunications jobs

HF divisions involved: Comms

Brief project description: Our inhouse PROX5 design team were tasked with completing a Stage 1 feasibility study for a mobile network operators vendor swap requirements whereby they would be removing 3 existing antennas and replacing them one new Hybrid AIR antenna per sector.

The Hybrid AIR antenna is designed to provide phone and WiFi signals while also offering transmission for 5G capabilities.

This new antenna upgrade would dramatically increase the current capabilities of the proposed tower site should the project go ahead.

Project Challenges: No active work had been completed on the antenna site since 2019. This meant that accurate visuals and up to date reports on the site structure were in short supply.

Because the site already had fixed transmission antennas installed (that were not to be replaced), the main challenge of this feasibility project was to come up with a new solution to meet the mobile network operators requirements while retaining the sites existing framework.

Our inhouse design team were more than up for the challenge and we were able to successfully complete the feasibility project for the client using our PROX5 software; proving that the system would fully meet current compliance.

London 5G Installation

Project length: 8 days
HF divisions involved: Comms

Brief project description: HF Comms were instructed to provide a 5G upgrade to an existing roof top telecom site in the centre of London.

The project required civil, rigging and electrical works to be completed and this required the project to be carried out in two key stages.

Stage 1

Civil works were required to install three new concrete plinths. This installation included waterproofing to accommodate a new steel tripod. A new wall mounted support pole was also installed to make the site secure.

Stage 2

Stage two required rigging works to be completed in order to remove legacy antennas and associated hardware. The new 5G antennas and hardware were then installed by the HF Comms team. This included installation included new DC cabling and new multicore fibre cables installation.

Once this was completed, electrical works were then required to install new DCDU units within the PSU so that all the installation hardware at top level could be powered up.

To complete the 5G installation, the HF Comms team worked along with the equipment vendor so that all new technologies were correctly integrated into the network.

The entire works installation was completed following HF Comms design according to customer’s instructions and industry specifications.

Project Challenges: Prior to the works starting, a Site Provider Pre-Start Meeting took place to agree the method statement on how these works will be executed. Once everything was agreed we were ready to progress to the build stage.

The installation required a new 5.25m tall tripod and a 6.30m wall mounted support pole to be installed. Due to the size of this and in order to lift the steelwork and antennas into position, both a crane and MEWP were deployed. To ensure site safety, barriers were used to cordon off the drop zone areas.

All equipment and materials were also lifted to the roof using the crane.

With accurate planning, we managed to complete the project in time, budget and quality required.

5G Upgrade Project

Client: Cellnex
Project length: 2 weeks
HF divisions involved: Comms

Brief project description: HF Comms were instructed to upgrade an existing telecoms site for one of the leading UK Mobile network operator’s and their planned 5G roll out.

The project required two stages.  Stage 1 required the removal of legacy antennas, cabinet and associated hardware and stage 2 was for the installation of the brand new 5G antennas and hardware. This included new cabling, new cabinet and complete upgrade of existing electrical works.

As always,  our Comms team designed the installation proposal with the customer’s requirements at the forefront.

before and after of 5g installation

Project Challenges:

For this 5G upgrade project, we deployed 3 antennas composed of a combination of 4G and a 5G antenna. This set up meant that each antenna was weighing approximately 140kg each and around 2.3m in length. Due to the weight and size of the antennas, the existing structure had to be strengthened with additional steel work.

In order to lift the antennas into position, both a crane and MEWP were deployed. To ensure safe access to site for these plant vehicles, we had trackway temporarily installed for the duration of the build works.

before and after track access

The existing telecoms site was to be accessed through a field which meant liaising with the site provider to ensure there were no issues with us having the trackway in situ throughout the build.

With prior planning, we managed to complete the project fully on time ahead of site activation.

Telecoms Equipment Decommissioning

Client: Arqiva Ltd
Project length: 2 weeks
HF divisions involved: Comms

Brief project description: HF Comms were contracted to decommission a redundant telecoms site and remove the equipment located on top of Glenfuir Court High Rise residential building in Falkirk.

We have been providing site decommissioning services for communications operators who have been consolidating your networks or needing systems removed for many years and can provide a full spectrum of equipment decommissioning services going all the way up to large scale radio site decommissioning and removal services.

before and after comms decommissioning

Project Challenges: We had to liaise with the local council for the decommission works to take place. This was because the main portion of the residential buildings car park had to be cordoned off during the work; as did the access to one of the entrances of to the building to ensure the drop zone for the works was not compromised.

The work required the use of a 130 tonne crane for the decommissioning and took two separate visits to complete. This was because of unforeseen inclement weather as well as a birds nest which we discovered under the site grillage. The nest and chicks were deemed likely to be that of a herring gull which commonly nest on flat roofed buildings like this. The bird eggs are incubated for around 25 to 33 days. Once hatched, the fledglings are dependent on parents and unable to fly for around 6 weeks. Herring gull have a single brood, so once the young leave the nest it is no longer be considered active.  Once this allotted time had passed, we were able to return for our second visit to complete the decommissioning work.

130 tonne crane

On top of these challenges, we were also required to complete the decommissioning work alongside separate elevator upgrade work that the residential building was also having completed at the time.

Customer quotes:

“A massive thanks to HF for finally getting this one over the line, it has been 18 months in the planning due to other ongoing projects, site has been decommissioned and all apertures sealed correctly to ensure the building is watertight”

Arqiva – Antennas Replacement

Client: Arqiva
Project length: 1 Year
Project value: £22k
Completion date: March 2019
HF divisions involved: Comms

comms services UK UK services contractor for Communications arqiva antenna fitting

Brief project description:  Removal of existing 3 x H3G and EE Racal 2212 antennas and replacing with 3 x new Commscope antennas. Also, the addition of 6 x new feeders, utilising the existing cable trays/feeder management system. Feeder trays and antennas mounted to the side of the gas holder, as shown in the pictures below.

Project Challenges : The biggest challenge we had with this project was the access to the gas site. There were vehicles parked all around the gas holder. 2 x MEWPs were required to facilitate the running of the feeder. One would be used to secure the feeder in multiple positions as it was pulled through. Having access to the necessary berthing positions for the MEWPs was essential in ensuring the work would be successful.

This was overcome by close coordination with SGN, as the owners of the structure, Arqiva, and our MEWP supplier and rigging team. We were also required to coordinate our activities with Nokia, as they were undertaking works on the ground-based cabin, in conjunction with our works.

Due to diligent planning, and close monitoring during the build period, the project was a complete success, finishing with a significant profit, and resulting in praise from the Arqiva PM, as he appreciated the difficulties overcome.

“Well done on this one as it was a horrible site to get access to and pass the SGN ‘roadblock’. Major site for customer as well”

 

Surbiton Tolworth Tower – Telecoms Dishes

Client: Arqiva
Project length: 3 Months
Project value: £119,000
Completion date: July 2019
HF divisions involved: Comms

Brief project description:  Relocation of all operators equipment to a temporary location was required to allow developers to start demolition works in readiness for redevelopment to luxury apartments.

We provided mobile telecoms dishes, antenna’s and cabinet relocation to new temporary location. Install of new electrical supply to temporary location.

 

Project Challenges: Due to the number of different parties involved in this project (Arqiva, landlord, developers construction company and 10 different operators), there were many challenges. Regular communication with all parties and amending timescales and scopes to suit all ensured everyone was kept up to date and agreements were made. Adhering to the 10 different operators differing scopes and timescales for outages was a great success with all going smoothly meaning no loss of networks. In amongst this was a large amount of decommissioning works carried out by HF to clear areas needed both by the developers for their works and by ourselves for relocation of operators kit. Communication and liaising with developers was key to the success of all this work. All this work brought about a very successfully completed project and within the timescales set, despite delays due to operators scope changes and over a month’s delay due to Peregrine Falcons nesting.

 

“I want to conclude by offering my earnest thanks and appreciation to the whole of the HF team, on and off site. All of the team is most well-motivated, professional and hard working. They have anticipated requirements and acted in advance to avoid any issues and delays. They have contributed valuable ideas to better the designs and plans, without deviating too far from either. It has been a real pleasure and a privilege to work with all of them.”
Mike Noel, Arqiva’s Design Manager

Arqiva – Orkney, Scotland

Client: Arqiva
Project length: 5 Years
Project value: £26k (Part of a £4.5m project)
Completion date: September 2019
HF divisions involved: Comms

comms smart meter installation

Brief project description:  Cew telecoms street works pole & cabinet installation on the Orkney islands for Smart Meter, project ran by Arqiva for the DECC.

Project Challenges: With 20+ years in the telecoms industry new installations are not uncommon for HF Comms, however building these sites on the islands always presents unique challenges. The biggest issue is that resources are limited and it can be difficult to source materials, plant machinery & subcontractors and any deliveries to site take a minimum of 5 days.

For this particular site we ordered all materials in advance which meant our engineers had everything required for the build before they travelled to the island. Transporting the pole and cabinet was the next big challenge, this is something that Arqiva usually arrange, however we engaged Northward Ltd to do this for us and they also had a hi-ab on the island so were able to land both the pole and cabinet for us when the time came.

We usually do the civil works for these sites ourselves however sourcing the various plant for this job proved difficult as there were only limited machines available. We engaged Andrew Sinclair Ltd for these works and they carried out the excavations and concrete pour. We re-attended site the following week to land the pole and give the DNO access to the cabinet to complete the jointing, Andrew Sinclair were also on-site to complete the backfill and tar re-instatement. All works were complete in time, within budget and with no issues.

 

“We were happy to engage with HF on their first SW pole build on the Orkneys, works were well co-ordinated and ran smoothly, not always the case when resource and plant are limited, job well done.”

Arqiva, Pontyberem – Tower Upgrade, Wales

Client: Arqiva
Project length: 4 Months
Project value: £50k
Completion date: October 2018
HF divisions involved: Comms

Brief project description: HF Comms were engaged by our client to upgrade an existing mobile phone communication tower in a remote part of Wales. Our scope of work was to install a 3 face headframe on an existing Arqiva asset replacing existing technology and enabling future growth and upgrade works.

Project Challenges: The remoteness and rural location meant that access to the site was considered difficult. The access route chosen by the site provider meant that should we use typical methods of access equipment such as trackway then significant damage over a large area would have been caused and the cost would have been high. To overcome this, we employed a specialist tracked crane to negotiate the steep terrain whilst causing minimal damage to the land. The method employed to deliver this site brought the following benefits;

– Cost saving of £25k to the client
– Minimal damage to site during access
– Accelerated Project Delivery
– Minimal outage / downtime of client asset / technology
– No requirement for a temporary tower
– Site Provider happy with time on site, end result and reinstatement

Huawei – ESN5153, Creagan Mor

Client: Huawei
Project length: 2 Weeks
Project value: £58k
Completion date: May 2018
HF divisions involved: Comms

Brief project description: Complete site build, including civil works, incorporating fencing, concrete plinth, electrical works and cable ducts.

Installation of a new 12.5m non-standard Hutchinson telegraph pole with antennas at 11.5m and dish at 9.2m. Installation of Blenheim and Link A/C cabinets on new concrete plinths.

Project Challenges: The biggest challenge we had with this project was the access route. The only vehicular route to site was via a steep and narrow track, which incorporated a bridge with a 3 ton weight limit. We overcame this challenge with the use of multiple helicopter lifts from a drop-off point close to the site location.

An additional challenge encountered was an active and prestigious shooting estate being in close proximity to the proposed site location. Our access was actually through the estate, therefore all movement to and from the site had to be coordinated in conjunction with the shooting estate management. We had a short window, when shooting was not taking place, to enable us to carry out our work.

The high-level plan of works was as follows:

CTIL – Catterick Garrison, North Yorkshire, England

Client: CTIL – Catterick Garrison
Project length: 2 months
Project value: £37k
Completion date: April 2018
HF divisions involved: Comms

Brief project description: Complete site build, including civil works incorporating fencing, concrete base, electrical works and cable ducts.

Installation of a new 20m Hutchinson tower with 2No SHF 0.6M HP dishes at 18.7m and 3No Kathrein antennas, also at 18.7m, with associated MHAs, cable trays and feeders. Also included was the installation of 1No Ericsson RBS outdoor cabinet and 1No Alifabs meter cabinet.

Project Challenges: The biggest challenge faced was access into the Northern Gas site. Although an Arqiva project, the site was owned by Northern Gas. Full supervision would be required for each daily task, however Northern Gas did not have the available resources to commit to daily supervision.

After a PSM, it was agreed that if we fenced off the area with Herras fencing, we could claim this land as Arqiva’s. We could then build a permanent fence, thus ensuring supervision would not be required within the compound for the civils works and for the tower build, as per the design.

Another challenge encountered was the access track for delivery of the tower. This was frequently used as a bridle-path. Full safety barriers had to be in place, and all parties were required to recognise that works would have to stop to allow horses and their riders to pass.

Furthermore, the crane could not park on this access track.

We had to explore other options to allow a crane lift:
If we used the access track, we would need notice to block off the path
If we used the nearby field, we would need to arrange access with a third party
If we used a normal 40-ton crane, we would need matting and trackway in the compound owned by Northern Gas, which was not accepted

HF were able to get a slimmer, tracked crane to be used within the Arqiva owned compound, thus negating the requirement for trackway. Subsequently, the costs and time constraints associated with the utilisation of trackway did not apply.

The installation was completed on time and within budget

telecoms upgrade

Project Challenges Overcame: Projects such as this are second nature to HF Comms, however working on remote islands always brings new challenges. This project was passed to HF Comms to build without ever being to the site. Our main challenges were to coordinate our engineers, accommodation, civil work, deliveries and on site issues with minimum disruption. We decided that couriers were not going to be reliable and due to location it would make sense for our civils team to deliver all kit to site, which happened without any problems. With the site being remote it was incredibly hard to locate subcontractors to complete the works. HF Skilled riggers worked through bad weather by prioritising certain works around the elements. We are glad to report all was overcome and the site was built on time. 4G is now provided to the residents. This was one of the first builds we completed for the client and following this we now undertake the account for them.
