Air Street, London

Located in the heart of the London’s Regent Street, this high profile project involves the refurbishment and extension of a Grade II listed office building, which remains partially in occupation with retail trading continuing on the ground floor throughout.

This project forms the latest element in The Crown Estate’s Regent Street Vision Investment strategy, which is a £1bn, 20 year programme of regeneration for Regent Street. This fits perfectly with Sisk’s policy to prioritise opportunities with long term repeat business potential.

Winning the tender required a robust logistics strategy as the site is bounded by Regent Street, with its high public footfall, and additionally accommodating the ongoing business requirements of the nearby Café Royale and Quadrant Arcade.

We secured this contract against tough competition, however our in-depth understanding of the scheme and our innovative temporary works solutions, together with our proven track record in consistently delivering challenging schemes for The Crown Estate ensured our appointment as Principal Contractor.

70 St Stephen's Green

The project is situated between two office blocks and fronts onto St Stephens Green South on the north and onto a laneway owned by the OPW on the south. Due to the location of the site there was a suite of environmental monitoring systems in place on and around neighbouring buildings together with scheduled weekly meetings with adjacent building occupiers and public bodies.

The building takes up the full footprint of the site resulting in a bespoke office accommodation solution on St Stephen's Green South and a detailed logistics plan drafted for the site to minimise impact on the adjacent buildings and utilise the limited amount of space on the site.

To construct the double basement a significant temporary works scheme was designed which involves propping neighbouring buildings to the east and west and footpaths/roads to the north and south. The proximity of neighbouring buildings and the limited storage space has also resulted in precast walls and post tensioned slabs being utilised from ground floor upwards.

The project is LEED platinum and WELL gold along with NZEB certified.

Wembley Arena

Sisk have completed work on the re-configuration of Wembley Arena, London’s primary live music venue.

The Grade II listed building was originally constructed in 1934 for the Empire Games and the £25m project is the first part of Quintain’s regeneration of the Wembley Stadium environs.

The arena has been reversed with the main entrance opening onto an exciting new public square and the new stage now has a covered service yard. The Arena has approximately 12,200 new seats, 9 large dressing rooms, promoter offices, a 200 seat restaurant, hospitality suites, a total of 10 dedicated bars and fast food outlets and a box office. The refurbished Arena offers excellent facilities for its customers and promoters.

The project was completed on time and on budget.

Station Building 2, Dublin

Station Building 2 involved the refurbishment and restoration of part of the former Harcourt Street train station and more recently the POD Nightclub. It is a significant landmark in Dublin city centre with renowned historical importance. The project therefore created a unique office and retail works space rarely experienced in the current marketplace.

This project comprised full external restoration of all external envelope, creation of new double height entrance foyer and reception, construction of new mezzanine floor area, ancillary storage and plant areas and the creation of a new public realm plaza to the Luas stop on Harcourt Street. The existing vault foundations below platform level were also restored to create retail and restaurant space in three large units and one smaller café style unit.

Arthur Cox

This project required the fit out of a six storey office block (13,700m²) over a double basement (4,500m²). Sisk constructed the shell and core under a separate contract and this overlapped with the fit out works. This is a city centre site with streets on three sides and an office restoration on the remaining side also carried out by Sisk. Access was via a rear ramp to the basement and an internal hoist in the central atrium gave access to each floor.

The shell and core is an RC structure main frame of columns, beams and flat slabs. One central lift and stair with two other ancillary stair cores. The main façade has punch windows which are a combination of structural glazing and curtain walling. The columns and slab edges are clad with hand fixed stone. The internal atrium is glazed in full height curtain walling and the courtyard has vertical fins for solar shading.

The fit out required installation of raised access floors, SAS tartan ceilings, system glazed and pre-finished partitions. The floor layouts are 80% cellular from first to fifth floor. The sixth floor has multiple meeting rooms with upgraded finishes for client and executive meetings.

The fit out consists of a raised access floor and metal tile ceiling with demountable office walls on floors one to five with a suite of meeting rooms on the sixth floor. The ground floor contains a full kitchen and dining area, central atrium with cantilevered feature stairs, training and lecture rooms. A full M&E installation was part of the fit out contract. The basement facilitates bike and car parking and the lower basement is fitted out with gym and utility rooms.

The project achieved LEED Gold accreditation.
