4 1. Design Criteria 1.1 THE DEVELOPMENT RETAIL UNIT 8 Retail Unit 8 forms part of the Barts Square development that lies within the City of London and the ward of Farringdon. It covers approximately 1.29 hectares encompassing a range of buildings on Little Britain and Bartholomew Close. The majority of the site lies within the Smithfield Conservation Area. Retail Unit 8 is a South facing unit located at the heart of the Barts Square development, and sits at the ground floor of a new build 6 storey residential building, topped by an overlooking penthouse apartment. This residential block wraps around the corner of St. Bartholomew s Close and features as a main focal point for two of the developments primary entrance routes, with Retail Unit 8 at its base facing the only public square on site. This square also acts as a break out space for the two neighbouring office buildings of the development AREA Retail Unit 8 provides approximately 135m2 of gross internal area, located at ground level PLANNING CONDITIONS AND RESTRICTIONS Retail Unit 8 has planning permission for A1-A4 uses OPERATING HOURS The permitted operating hours for all retail units on the estate are 7:00-0:00 Monday to Sunday. 1.2 STRUCTURE FOUNDATIONS The building foundation consists of a 1000mm loadbearing raft slab SUBSTRUCTURE The building substructure is an in-situ reinforced concrete basement box with a concrete waterproofing additive and a secondary localised waterproofing membrane SUPERSTRUCTURE The building superstructure is an in-situ reinforced concrete frame. 1.3 FIRE OCCUPANCY (FOR ESCAPE CALCULATION PURPOSES) A risk profile of B2 has been allocated to the retail space based on an occupancy of 2 sqm/person FIRE STRATEGY Retail units shall evacuate in isolation on confirmed fire detection within their demise. Retail unit tenants will be responsible for installing their own separate stand-alone fire detection and alarm systems, which will interface and communicate with the Landlord s main fire alarm system in the event of a fire. An interface from the Landlord System will be provided. The Retail Tenant can request a copy of the Fire Strategy, prepared by the project Fire Engineer, for further detailed information. 1.4 ACOUSTICS DESIGN CRITERIA The planning conditions expressly stipulate that no live or recorded music shall be played that can be heard outside the retail premises or within adjoining premises to the retail units. The retail tenant will be responsible for appropriate acoustic treatment to the internal fabric of the unit to achieve this. Additionally, doors and windows are not to be propped open for any length of time. The fitout of Retail 8 shall be designed to restrict the impact of noise on the external environment and to protect the amenity. In particular, noise emissions will comply with the planning condition, which stipulates that 37 dba will need to be achieved at nearby facades. The Retail Tenant can request a copy of the Acoustic Design Criteria, prepared by the project Acoustic Engineer, for further detailed information NR LEVEL Internal building services noise level are to be determined by Retail Tenant. If the internal environment is such that the noise level is above that stipulated in the Planning Condition (such as loud music etc.) then the Retail Tenant will be responsible for acoustically treating the internal fabric to achieve the required criteria. 2. Building Envelope 2.1 PERFORMANCE AND TESTING The windows and ground floor door are modern systems that provide improved thermal performance, to achieve the requirements set in Part L2A. The ground floor envelope is designed to achieve a U-value of 0.18 W/m2K. The ground floor shopfornt glazing is designed to achieve a U-value of 1.6 W/m2K and doors a U-value of 1.6 W/m2K. 2.2 EXTERNAL WALLS, WINDOWS AND DOORS Retail Unit 8 facade is composed of masonry cavity walls clad with deep reveals of ashlar stone and flush pointed white cement. Lintels are comprised of stone faced precast concrete elements with stone soffits resting on stone reveals to each window, and natural anodised aluminium flashing to match adjacent curtain walling. Between these stone clad reveals sits an anodised aluminium framed, thermally broken, double glazed, shop front window system with full height glazing System surrounds are custom fabricated, insulated metal casings, mechanically fixed and sealed to the surrounding concrete structure to maintain thermal and weathertight continuity to all edges. 2.3 EXTERNAL DOORS Entrance to the unit is provided by a slim profiled, full height anodised aluminium glazed door. 2.4 SIGNAGE A site wide strategy has been developed to incorporate specific Retail Tenant signage. Retail Tenant signage can be installed behind the glazed panels adjacent to the entrance doors, with graphics applied to the fixed hanging signs, in accordance with the design parameters. This is indicated on the retail elevation drawings and the hanging sign drawing in Section STRUCTURAL SLAB LOADING SDL = 2.50kN/m², where SDL refers to Superimposed Dead Load and encompasses floor finishes and suspended ceiling loads, and LL = 5.00kN/m², where LL refers to Live Load and is the variable load related to occupation STRUCTURAL TOLERANCES The maximum deviation of structural slab level from design slab level is +/-10mm. The permitted deviation in the difference in level of a slab will not exceed 15mm. The maximum deflection of any slab inclusive of Super Imposed Load deflection plus remaining dead load deflection is 15mm. 4 BARTS SQUARE, LONDON EC1 - RETAIL 8 INFORMATION PACK

It should be noted that the retail waste entry is on Bartholomew Close and the floor level is lower due to the slope in the pavement (refer to detail 1 on 4384-SK-1495) The waste storage should accommodate the following which has been agreed with the Planners: 1 x 660 litres bin for recyclables 1 x 660 litres bin for residual 1 x 360 bin for organics. It is the tenant s responsibility to organise waste collection of a suitable frequency. The CoL currently do not offer collection of commercial waste therefore a contract will need to be entered into by the tenant with a licensed private waste contractor who can be given direct access to the bin store. Waste must not be left on the street at any time. The collection point is located on drawing 4384-SK BARTS SQUARE, LONDON EC1 - RETAIL 8 INFORMATION PACK
