BARTS SQUARE, LONDON EC1 - RETAIL 6 INFORMATION PACK 3

1. Design Criteria1.1 THE DEVELOPMENT

1.1.1 BARTS SQUARE

Retail 6 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 (by reference to the red line site boundary) that encompassed a range of buildings on Little Britain and Bartholomew Close. The majority of the site lies within the Smithfield Conservation Area.

Retail 6 is a double aspect retail unit at the ground floor of a six storey brick clad residential block. Retail 6 is entered from Little Britain close to Bartholomew Close.

1.1.2 AREA

Retail 6 provides approximately 107.8 sqm (1160 sqft) of gross internal area (including columns), located at ground level. Final area to be confirmed subject to measured area survey post completion.

1.1.3 PLANNING CONDITIONS AND RESTRICTIONS

Retail 6 has planning permission for A1 use noting that the doors and windows of each unit are to be kept closed except for entrance and exit use.

1.1.4 OPERATING HOURS

The permitted operating hours for all retail units on the estate are 7:00 - 0:00 Monday to Sunday.

1.1.5 PREMISES LICENCE

All premises licensing is subject to separate planning application by Retail Tenant.

1.2 STRUCTURE

1.2.1 SUPERSTRUCTURE

The superstructure is an in-situ reinforced concrete frame.

1.2.2 STRUCTURAL SLAB LOADING

SDL = 2.50kN/m², where SDL refers to “Superimposed Dead Load” and encompasses floor finishes and suspended ceiling loads.

LL = 5.00kN/m², where LL refers to “Live Load” and is the variable load related to occupation.

Maximum deflection of any slab inclusive of Super Imposed Load deflection + remaining dead load deflection = 15mm.

1.2.3 STRUCTURAL TOLERANCES

The as built survey information provided by Site Engineering Surveys Ltd is included in Appendix A. Refer to survey drawings for slab and threshold levels

1.3 FIRE

1.3.1 OCCUPANCY

A risk profile of B1 has been allocated to the retail space based on an occupancy of 2 sqm/person.

2. Building Envelope2.1 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 external walls are designed to achieve a U-value of 0.27 W/m2K.

The ground floor shopfront glazing and doors are designed to achieve a U-value of 5.5 W/m2K.

In order to mitigate the occurrence of condensation either localised control measures (such as heat curtain) or space wide (general heating and humidity control) should be considered as typically adopted in retail outlets in London..

2.2 EXTERNAL WALLS, WINDOWS AND DOORS

Shopfront screens are enclosed by projecting bronze anodised aluminium picture frames with frameless single glazed window units. Window surrounds are custom fabricated, insulated, bronze anodised aluminium casings, mechanically fixed and sealed to the surrounding concrete structure to maintain thermal and weathertight continuity to all edges.

Solid external walls are brick faced precast panels lined with insulation and a vapour barrier. The Retail Tenant will install the finishing wall lining, ensuring that the junction with the shopfront glazing follows the dashed line on the retail unit drawing in Section 6.

No changes are to be made to the facade by the Retail Tenant without the written permission of the Landlord.

2.3 FACADE ACCESS

Facade access and maintenance is proposed to take place at pavement level with periods and operations to be confirmed by the Estate Management.

2.4 EXTERNAL DOORS

Bronze anodised aluminium framed double glazed, 2200mm tall single leaf, shopfront doors with solid bottom panels and polished bronze vertical pull handles.

The doors are manually operated, with no power assistance system provided. The doors are however capable of having a power assistance system added as part of the Retail Tenant fit-out. Suitable automated door gear is available from Tormax, Dorma or Geze. Refer to door detail drawing in Appendix A.

2.5 SIGNAGE

The Tenant may install retail signage internally behind the glazed panel over the entrance doors. The extent of this zone is indicated on the retail elevation drawing in Section 6.

The Tenant can add retail graphics, subject to Landlord’s approval, to the external illuminated sign provided by the Landlord. Wiring for illumination of the sign is provided into the retail unit. Details of the external sign are provided in Section 6.

Additional seasonal signage may be applied to shop front glazing, if desired, subject to Landlord approval.

1.3.2 FIRE STRATEGY

Retail units shall evacuate in isolation on confirmed fire detection within their demise.

The Retail Tenant 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 is required to provide sprinkler protection with the retail unit. Refer section 4.5.2.

The Retail Tenant can request a copy of the Fire Strategy, prepared by the project fire engineer, for further detailed information.

1.4 ACOUSTICS

1.4.1 DESIGN CRITERIA

The operation of the retail units should not be audible in the apartments or any adjoining noise sensitive residential use area.

Practically this is achieved when the noise from the retail unit is sufficiently below the background noise level within the adjoining space and free of attention catching acoustic features, such as impulsivity or tonality. The acoustic criteria is set at a level below the background noise level generated by the building services, limits the maximum noise levels (impulsivity) and sets low frequency limits (tonality) through considering the sound insulation provided by the party floor.

In order to achieve the limits within the adjoining space it will be necessary to limit the noise produced in the retail unit and also enhance the sound insulation.

The Acoustic Design Criteria, prepared by the project acoustic engineer, is included in Section 6.

1.4.2 NR LEVEL

Internal building services noise rating levels are to be determined by the Retail Tenant.

1.4.3 SUBMISSIONS

Details of the tenancy are to be provided to the Landlord’s acoustician for assessment prior to installation. The following details are to be provided by the Tenant’s acoustician.

• The proposed use of the tenancy, eg restaurant, shop etc

• Operating hours of tenancy

• Details of amplified sound systems and any control measures to be adopted (if any)

Drawings illustrating the designs to be adopted for enhancing the sound insulation (if any)..

5.3 CLEANING STRATEGY

Access to the facade for cleaning is proposed to be carried out by the Retail Tenant via direct hand access with “Window Vac” or “Squeegee” from street level. This must take place outside core business hours.

5.4 DELIVERY STRATEGY

The consented development does not include off-street vehicular access for servicing and refuse collection – all deliveries and waste collection are to be provided via on-street vehicular access as discussed and agreed with the City.

Retail deliveries are likely to presented via the retail entrance at ground floor.

The primary goods in route will be from Little Britain.

5.5 WASTE DISPOSAL AND COLLECTION STRATEGY

A waste storage room is provided for Retail Unit 6 (6a/6b) located at ground floor on Bartholomew Close. Please refer to drawings 5294-PH3-20-350 and 5294-PH3-20-351.

All waste from the retail unit will be segregated at source into:1 x 660 litre bin for recyclables and 1 x 660 litre bin for residual.

Once in the retail waste storage room, the waste will be managed by the Barts Square FM team. The CoL council do not currently offer collection of commercial waste. It is therefore assumed that all commercial waste from the development will be collected by a licensed private waste contractor. On the designated collection days, the FM team will move waste bins to the service lobby area, where they will be temporarily retained. Waste contractors will then access the service lobby from Bartholomew Close and service all the required bins.

From: Philip Owen Reviewer: Stephen Stringer

Barts Square Phase 3, London Retail pack – acoustic requirements

Sandy Brown have reviewed the level of sound insulation that is provided by the shell of Phase 3 of Barts Square in order to provide recommendations and guidance on the acoustic requirements between the retail units and adjacent noise sensitive spaces.

Proposed design Apartments are located above retail units in each residential block in Phase 3. The party floors in each instance are designed to achieve 5 dB better than the minimum required for compliance with the Building Regulation requirements, eg DnT,w + Ctr 50 dB.

The level of sound insulation achieved by the floor party floors above each retail unit will provide reasonable protection against typical retail or quiet cafe uses. However, if a prospective tenant is expected to have uses with higher noise levels (eg high levels of amplified music), it would be a requirement on them to enhance the sound insulation.


Page 2 of 4 15328-M011-A RETAIL PACK ACOUSTIC REQUIREMENTS

Design requirements The operation of the ground floor retail units should be practicably inaudible in the apartments above. To achieve this, it is recommended that the noise levels, when assessed or measured in the residential spaces are no greater than those outlined below:

• LAeq,1mins 20 dB

• LAFmax 25 dB

• Leq,1mins 35 dB at 63 Hz

• Leq,1mins 30 dB at 125 Hz.

Tenancy operational noise levels and airborne sound insulation enhancements

The above design targets for noise intrusion will be achieved through a combination of controlling noise levels in the tenancy and where appropriate enhancing the sound insulation. Guidance on the levels of noise allowable in the tenancy (to be controlled through means of an electronic sound limiter) and appropriate sound insulation enhancements are provided in Table 1.

Additional design requirements to mitigate impact/structure-borne noise

In addition to the guidance provided in Table 1, it will be necessary to consider the impact sound transmission from the retail units to the noise sensitive spaces in the building. It is recommended that the retail units are fitted out with a floor construction that provides a maximum impact sound insulation rating of L’nT,w 59 dB or lower.

Servicing of tenancies

It will be necessary for the tenant to appropriately manage all activities that could result in adverse noise effects being experienced by the nearby residents. This is likely to limit collections and deliveries to the daytime.



Use of outdoor spaces

It is recommended that the use of outdoor spaces during the evening/night time periods are considered in the tenant agreements. It is recommended that if there are expectations to use outdoor spaces that restrictions are incorporated into the agreement to control the noise emissions, such as limiting the number of spaces available outside and not allowing amplified music.

In order to determine the appropriate restrictions, it will be necessary for a separate acoustic assessment to be completed. The acoustic assessment could be completed by the prospective tenant, though it should provide adequate information to demonstrate that the proposed use agrees with the acoustic requirements outlined above.
