Case Study of Hampton Court Palace

Hampton Court Palace

Background

The Royal School of Needlework recently expanded its teaching area within Hampton Court Palace adding classrooms, an office, library and an IT room.

Project Outline

Sigma Networks worked closely with the Royal School of Needlework to oversee the installation of a fibre optic backbone and voice multicore cabling between the existing and new rooms on opposite sides of the Palace.

As part of the project a comprehensive Category 5E structured network was installed.

Customer Comments...

Sigma demonstrated a high level of professionalism, care and sensitivity both during the project planning stages and throughout the installation, working closely with Julia Grinham in the Surveyors department of Historic Royal Palaces to protect and safeguard the integrity of this listed monument.

Case Study of Dixons Stores Group, Newark

Dixons Stores Group

Background

DSGi is the UK's leading electrical retailer, with Currys and PC World stores in the High Street and Dixons.co.uk on the internet.

Project Outline

In December 2009, DSGi built an extensive TV, PC and laptop repair centre within their main nationwide distribution centre in Newark, Nottinghamshire.

The project involved the installation of over 1,000 Category 5e data outlets and 600 TV aerial sockets to serve the new repair workbenches. In addition, we created a brand new Comms Room, served by fibre-optic and voice multicore backbone cabling.

The building's TV distribution system had to be completely redesigned to support the new requirement, and the internal data network reconfigured to accommodate the new Comms Room. Despite a lengthy planning and design stage, the installation timescales were extremely short, as the repair centre needed to be up and running prior to DSGi’s peak repair period in January.

Our 12-strong installation team work weekend and night shifts in order to ensure the project was completed on time and within budget.

Case Study of Perse School for Girls, Cambridge

Perse School for Girls

Background

Sigma have been working in partnership with Perse in Cambridge since 2003.

Project Outline

In March 2010, we were asked to relocate and upgrade the Free Space Optics laser that links the data networks between the Main Upper School and the Junior School, located several streets away. The existing link was a 100Mbit unit, but the school wanted to establish a Gigaspeed (1,000 Mbit) connection.

The faster units were much larger and heavier than the existing lasers, so some innovative thinking was required to ensure the mountings were robust and secure enough. Fibre-optic cabling was required to feed the new equipment, which also required a mains power feed.

Customer Comments...

Engineers from Sigma’s data, fibre and electrical divisions ensured that the project was completed during the Easter break, ready for the pupil’s return at the start of the term.

Case Study of Tottenham Hotspur Football Club

Tottenham Hotspur Football Club

Background

Sigma Networks has undertaken several large cabling projects at Spurs, including the refurbishment of the West Stand offices, and the new Club Shop. In all cases, timescales were tight, with strict specifications on materials.

Project Outline

We needed to install cabling within very busy site environments, as a wide range of trades were working at the same time. We also needed to project manage these jobs very carefully, as extensive liaison with BT and other network providers was essential to ensure that there was no loss of service to the club during the project.

We were also asked to provide temporary solutions during the project, so that the club was able to function as normally as possible during the refurbishments. This required a high level of flexibility, and some quick thinking, as we were sometimes called upon at very short notice.

Customer Comments...

Sigma Networks are now our preferred choice for all our internal data cabling – the service we have received from them has always been exemplary.
James Hughes, Stadium Manager

Case Study of the Greenbank Hotel

Greenbank Hotel Cornwall

Background

This project was undertaken in the spring of 1999. Although the hotel was being refurbished, parts were still open to guests. Our task was to completely renew the voice cabling within the hotel, from each of the 87 guest rooms and numerous offices, back to a newly-created Comms Room in the basement.

Project Outline

The challenge here was to complete the installation, whilst remaining as unobtrusive as possible. Half the hotel was effectively a building site, with many trades all working simultaneously, the other half was occupied by guests. A flexible approach was essential, as there were major restrictions on access and the use of power tools. The job was also subject to tight timescales, as the work needed to be completed prior to the start of the summer season.

Sigma Networks completed the task a full two weeks ahead of schedule and within budget.

Customer Comments...

The engineers from Sigma were a delight to work with. We had to impose tight restrictions on working practices to ensure our guests were disturbed as little as possible by the building work going on around them. The engineers from Sigma stood head and shoulders above the contractors we had on site in terms of flexibility, politeness and a generally helpful attitude.
Yvonne Palmer, General Manager
