Main Contractor:


Situated in close proximity to the Bank of England, 120 Old Broad Street is a 49,000 sq. ft multi-let, six storey office building of reinforced concrete construction dating from 1993.  The building has a basement, lower ground floor, ground floor and six upper floors. EPAM commenced managing the building in June 2011 and have since refurbished the majority of the offices on a floor by floor basis, renewing the outdated HVAC system and introducing bike and shower facilities. The central plant is predominantly split between roof and basement with dedicated vertical risers connecting tenanted floors.

120 Old Broad Street underwent a phased replacement and upgrade of the existing building management system (BMS). These works will included a new BMS communications network, network controller outstations and on-floor fan coil unit controllers. The new TREND IQ BMS system ran concurrently with the existing Schneider BMS while each floor had the relevant hardware and software installed. The project was phased on a floor by floor basis with the major MCC’s, outstations and BMS headend PC upgraded first.

The scope required to upgrade the existing and obsolete Schneider Vista building management system (BMS). The Schneider Vista headend was no longer supported and the local Fan coil unit controllers- Xenta TAC were no longer available. Hive were appointed to undertake a feasibility study, performance specification and carry out on site project management duties. The site was transitioned over to the Trend IQ Vision platform, on time and within budget.

A feasibility study was undertaken prior to the tender stage to ascertain the best possible platform for the migration works. This identified the most cost effective route to market. The main challenges included overcoming the inherent issues with the base build MEP systems which required significant works to enable full control and integration into the new BMS. Hive identified energy efficiency savings which included VSD drives and including efficient software routines to greater control energy usage and reporting.
