Description Comments Compliant General floor area N/A as per Table C2.2, Classification 9b all compartments within limitations the building are under 8000m2 floor area and the volume of the largest gallery, that being the one on the 4 floor, has a total cubic volume of 19502m3, which is applicable with its type A construction.

Furthermore when defining, “Fire compartment” under the BCA, Definition B ii is to be noted. All walls and separations of gallery’s spaces and floor spaces are to be engineered and designed to have an applicable FRL rating for their type of construction in this case Type A Large isolated Not directly applicable given all fire compartments are within the buildings range allowable in table C2.2 However, vague wording in C2.3 which states the building does not exceed 18,000m2 which with the wording ‘building’ and not fire compartment could apply, on which case. As per C2.3 a ii as a class 6 and 9 building the building must be protected with a fire sprinkler system complying with Specification E1.5 and further must provide vehicular access complying with C2.4b Requirements for As required by C2.3 a permitter around the whole building must be open spaces and accessible by fire trucks with a minimum unobstructed width of

6m, further at no point must the distance of this permitter as per B ii exceed 18m from the building and if bounded by a public road (N/A to this building) may be included in the 6m width.

As per C2.6 given the buildings Type A nature and the use of an entirely glass façade external ‘wall’ which classifies as an opening, Spandrels compliant with C2.6A must be used to prevent fire traveling between floors, As outlined the spandrel must be not less than 900mm in Height and extend no less than 600 into the upper floor and be of FRL no less than 60/60/60 In the case of this building.

However, given the Aesthetic impact of Spandrels on the desired floor to ceiling glass panels it is recommended that that caveat of requirement b stating that the requirements of A do not apply to a building fully sprinklered which is compliant with e.15.

As per 2.7c Fire compartments throughout the building have been established as marked in the diagrams, As such all fire compartments must be constructed in accordance with A which specifies that the fire wall has the relevant FRL prescribed in SC1.1 Table A, Further more as per C2.7 A ii it is very importantly noted in C2.7 ii that any opening within the fire wall (windows included) must not reduce the FRL required by Specification C1.1 except where permitted as per part C3 protections of openings, these protection have been described in part C3 of this report

As per C2.7b it should also be noted that the Class 6 elements on the ground floor are to be treated as a separate buildings given there requirement for a FRL rating greater than the remainder of the building, for this reason as per C2.7b I, ii, iii the Class 6 spaces are contain an FRL rating appropriate that continues to the floors, ceilings and walls essentially making them little independent high FRL boxes

As per C2.8 and similarly to C2.7 the Class 6 elements on the ground floor are required to be separated from the other class objects by a Fire wall having an FRL of the higher of the two classifications. In this case as Class 6 elements need Type A construction requiring Fire walls, as per Table 3 the FRL rating is to be 180/180/180 As per C2.9 and similarly to C2.7, As a Class A construction, the Class 6 Elements on the ground floor, which are below the adjoining Storey of class 9b gallery spaces require The floor construction to have an FRL of the greater of the two required FRL’s . In this case an FRL of 180/180/180 as Prescribed in Table 3 of Specification C1.1 is the greater of the two, with the class 9b requiring 120/120/120 As per C2.10 the lift connecting floors, 1, 2 and 3 does not require to be enclosed in a lift shaft as it only connects 3 storeys within a sprinklered building. However if it was to be enclosed by a lift shaft as a Type A construction relevant FRL ratings of 120/90/90 as per Table 3 in C1.1 would be needed.

All though not shown in plan as actual services would need to be engineered, adequate service space has been provided within the building. It should be noted however that Fire pumps must be Fire isolated as per C, which specifies compliance with AS2419.1. As per D all fire pumps must be separated from all other services and an FRL of no less than 120/120/120 for floor ceilings and walls. All other equipment must comply with c2.12 when being arranged within the allocated services spaces however it should be noted that air pressurisation systems do not require D compliant separation.

Y C3.3 does apply within this building as a Class 9 Type A construction. As per C3.3 A, with the caveat ‘unless’ those walls have an FRL of 60/60/60 AND any opening protected in accordance to C3.4. All walls within the building require a minimum FRL of ‐ /90/90 as per Specification C1.1 Table A, and thus all fall within this allowance. See C3.4 for compliance in this area Y As per C3.4 and in relation to C3.3 all doors and entrances to separate fire compartments must fall within the acceptable methods of protection. C3.4 A,I b outlines that Doorways must be protected by ‐/60/30 self‐closing fire doorways compliant with AS1905.1 and are done so as outlined in the diagrams it should be noted sprinklers are used throughout the building but avoided where possible to avoid damage to the artwork located within

All windows throughout the building are compliant with ii B by being fixed in the closed positon with a minimum FRL of ‐/60/‐ and further comply with Specification C3.4 with all glass matching the tested prototypes as per the manufacturers instruction, Y As per C3.5 all doors comply by not taking up more than ½ the length of a fire wall, furthermore as outlined in the plans each door, where a single door has been used maintains the minimum FRL of that wall, in the case of the 9b elements, 120. As outlined in the plans all doors are self‐closing or automatically closing, where the automation is triggered by an AS1670 compliant Smoke detection system (E2.2) or instruction from a fire control panel.

All sliding doors within the building are compliant with C3.6 and remain locked in the open positon during normal building operation and triggered in the same way as the other doors.

Further precautions have been taken with the installation of warning signs above the door, flashing lights and alarm to alert building occupiers of the sliding door.

See plans for specific door details As per C3.9 all services remain outside of the fire isolated exits and fire isolated passageways throughout the building, electrical wiring is used through the passages for lighting, speaker systems and the pressurisation ergo it does penetrate the walls however as per C3.9a this is permitted as is the water supplies and the air pressurisation systems which are required for the fire isolated exits N/A Lifts are not required to be fire isolated N/A

N/A no class 2,3 or 4 elements

As per C3.12 all services within the building passing through the floor plates and fire compartmentalisation walls have an FRL greater or equal to the FRLs outlines for those specific elements as shown in the plans.

As per C3.12 b as a Type A construction the services in the building must further be protected by a shaft complying with specification C1.1 in particular requiring as per Table 3, an FRL for a ‘shaft’ if non loadbearing as they are throughout the building have a FRL of no less than ‐/90/90 or if load bearing 120/90/90 further more as stated by Specification C1.1 2.7 the shafts must be enclosed top and bottom by caps of the same required FRLs. In the case of this building being a Class 9 building In all area apart from a small portion of the ground floor, the required FRL for these services must therefore be 120/120/120 as all other aspects of the building where the services run through require this FRL 2.7 A and B do not apply to this building Openings in shafts N/A with the specific wording of C3.13 there are no shafts which explicitly and exclusively provide pipe, ventilation or garbage. If however it is referring to the Shafts required between floors for services such as those outlines in C3.12 then a Access panel of Frl not less than ‐60/30 must be installed Openings for As roughly drawn in plane there are numerous services throughout service the building which are required to penetrate the fire

eng compartments of the building. It is assumed presently that electrical, hydraulic (water), mechanical (air intake and conditioning as well as extraction) and on the ground floor café, gas are used throughout. As per C3.15 these services which cause opening in walls requiring FRL must not compromise the overall fire resisting effect of the building and specifically must not lower or in any way inhibit the required FRL of the fire walls or services shafts required in C3.12. For the electrical ducts, air extraction pipes and water pipes, FRL appropriate rated fire collars will be installed provided they have been tested and Comply with AS4072.1 and AS1530.4 and Thus C3.15a The mechanical ventilation and air conditioning systems which for a building of this scale requires further mechanical engineering. These must also be compliant, as per C3.15b, with AS1668.1. Gas pipes should also be fitted with one way valves and only penetrates directly into the Class 6a Kitchen from beneath the slab, the pipes should also be further constructed from copper.

SECTION D Access and Egress Part D3 ACCESS FOR PEOPLE WITH A DISABILITY

Clause D3.1

Description General building access requirements

D3.2

Access to buildings

D3.5

Accessible car parking

21293912

Comments As per Table 3.1 in the case of the Class 9b, 6a and 6d elements of the building it is required that all parts of the building are accessible where occupants are usually expected. With no dedicated installed seating areas within the building however the clarifications with requirements for wheel chair accessibility to wheel chair approved seats need not apply but should be considered when the spaces are used for exhibition after final completion

As per D3.2 a all parts of the building deemed to be required to be accessible as outlined in 3.1 must have a method of entry that is accessible, as can be seen in the drawings. Further as per D3.2 b ii as a building of an area greater than 500m2 all accessible entrances must be within no more than 100m of each other if a non‐accessible door operates between them at the 50m point. In addition as per C any entrance with more than 3 doorways must have 50% of those doorways be accessible. This is of note for the ground floor in particular where all entrances are accessible and well within 50m of one another.

As per D3.2e Automatic Accessible opening and closing entrance doors on the ground level are installed to allow accessible entrance to the building without requiring the dimensional spacing outlined in D3.2. It should also be noted that all ramps throughout the building are wheel chair compliant and hence there are no areas within the building that are not accessible to people requiring access accessible by non‐access dependent people N/A given no car parking has been allocated with in the design however parking in other areas around Helsinki such as the parking in the park should be accessible to service the Guggenheim and

therefore should comply with D3.5 as follows. Up to 1000 car parking spaces, (assuming the park has around 500) there must be 1 accessible space per 50 spaces, assuming 500 spaces this would mean 10 accessible spaces. The Spaces must further comply with AS2890.6 and the actual carpark must be designed so if the 500 spaces are split up (which being a park they would be) if there is only 5 spaces in the group the 5 are not purely accessible creating some sort of disabled only car park As per D3.6 all bathrooms within the building are fitted with AS1428.1 braille and tactile, Complying signs. Furthermore as per D3.6 a ii all doors outlined as required exits as per E3.4 are required to have accessible AS1428.1 compliant signs. This means all signs must be placed adjacent to the doors allowing egress to required exits, horizontal exits and horizontal exits. The signs must read ‘EXIT’ and ‘LEVEL as per level. All pedestrian access points within this building are also accessible as shown in the plans therefore signage is not required for this part. Furthermore all bathrooms within the building are banked together therefore an accessible and ambulant WC is available In all and signed as mentioned. *Note due to the scale of the plans at 1:500 showing precise locations is not legibly N/A Hearing augmentation is not required as there is no inbuilt amplification system installed in the building. D3.7 should however be noted if in any upcoming exhibitions artists wish to install speaker systems within the gallery in which case they should ethically allow for hearing augmentation to create an inclusive environment which the Guggenheim promotes N/A no fixed seating is provided within the building due to absence of lecture theatre or amphitheatres, all chairs are to be placed as per exhibition. However if seating is installed for an exhibition it is assumed to be temporary but should still remain compliant with AS1428.1 and remain accessible to wheel chair users. As per Table 3.9 wheel chair seating should be calculated. It is assumed that no more than 800 seats would ever be used to in an exhibition therefore in this case 16 accessible wheel chair seats must be provided grouped in no more than 5 per group.

SECTION E Services and Equipment Part E1 FIRE FIGHTING EQUIPMENT

Clause E1.3

21293912

Description Fire hydrants

Comments As per E.13a a fire hydrant system is required since it has a floor area greater than 500m2 and the fire brigade is available to attend the building. Therefore as per E1.3b the Hydrant system installed is compliant with AS2419.1 and also further only serve one floor Hydrant Fire hose reel combinations can be seen in the plans.

It should also be noted as per E1.3bthe Hydrant system must not be connected to the main town supply especially in the case of this building due to the potential loading it may draw from the system as such, the hydrant system must have installed tanks that provide one hour of water for the building, a fire engineer will be required

to locate external hydrants and calculate capacities compliant with AS2419 however rough locations of external tanks can be seen in the plans.

Y E1.4 applies to this building as a class 9b and class 6 building, fire hose reels must be provided in area where a Hydrant is installed (as per e)or further where a fire compartment has a floor area greater than 500m2 as per E1.4b. The fire hose reels must serve only those floors in which is installed and comply with AS2441 and may be used in combination with internal and external systems to achieve the required coverage.

Fire hose reels must also be located within 4m of an exit apart from those required to achieve coverage as per E. In order to achieve this coverage as well Fire hose reels may not pass through doors in order to achieve coverage apart from service closets and shaft access points. As can be seen in the plans, fire hose reels and fir hydrants have been located around the building as to comply Furthermore given the buildings size and height it is assumed that water pumps will be required to boost pressure to the top of the building and it is also assumed that on site water storage will be needed to meet the requirements of AS2441. Pumps have not been drawn in however adequate service space exists within the building, they require FRL120/120/120 floors roof and ceilings wit

Y As per TableE1.5 the Class 9b elements of the buildings require sprinklers as per Part H1 in all halls and gallery spaces as outlined in H1.2, The sprinklers installed must further comply with Specification E1.5 which outlines that the sprinkler systems must comply with AS2118.1 as per SE1.5 2 a .

Given the desire not to use sprinklers in the gallery spaces, as per SE1.5 3, the areas not covered by sprinklers must be Fire separated and satisfy the deemed to comply regulations, I.e following the Floor and wall FRL guidelines specified in part C with fire compartments. It would be recommended that a fire solution be further investigated however as deemed to satisfy requirements have been met by using sprinklers throughout the building.

Sprinklers are not depicted in plan however they cover the whole building and would need to be designed by a fire engineer.

As per E1.6 Fire extinguishers are to be provided as per Table E1.6 Y which states general provisions as per AS2444. In this case fire extinguishers will need to cover Class AE or E in the emergency switchboard locations which is defined by note 1 of table e1.6.

Given the building is to be fully covered by fire hose reels as per D of table E1.6 no further fir e extinguishers are required as all other risk classes are not present within the building.

Comments

ARCT4430 Compliance Report 2 E2.2

General requirements

Smoke management system will need to be designed and specified N seek by a mechanical consultant, however as per Table 2.2b, Class 9b eng exhibition halls, which constitutes the majority of the building, require an automatic shutdown of all air handling systems installed in accordance with section 5 and 11 of AS1668.1 if the air handling system does not also form a part of the smoke handling system.

This shutdown must automatically occur in the event of the triggering of SE2.2a compliant smoke detectors and SE1.5 compliant sprinkler, alarm and fire detection systems which are to be installed throughout the building. All smoke detection systems must further activate the air pressurization systems for fire isolated exits and the systems to control them must be compliant with AS1668.1. Smoke detectors must also be installed alongside all lift doors.

Smoke detectors must be spaced no more than 20m apart and no more than 10m from a wall and in the Class 6 elements of the building no more than 15m apart and 7.5 m from a wall. They must further be AS1668.1 compliant for sensitivity and it is recommended and assumed given the double height super scale nature of this building specialist smoke detectors will be required to achieve the 0.5% smoke obscuration per metre requirement outlined in SE2.2a 5 b iv

All air pressurisation systems located within the fire egress routes must further be automatically activated by AS1668.1 compliant smoke detection systems as is general with activation system the detection systems must be located outside all doors leading into the pressurised area See plans for rough locations of smoke detectors

SECTION F – Health and Amenity Part F1 DAMP AND WEATHERPROOFING

Clause F1.1

‐ Seek Eng

21293912

Description Stormwater drainage

Comments As per F1.1 all stormwater drainage is to be engineered to comply with AS3500.3 a Hydraulic engineer should be employed to approach this given the scale of the building and the sheer volume of the rain water it has the capacity to catch, however the following must be considered When considering the design of the roof for drainage it should be noted that the total is split into two parts over the roof garden with the primary part covering a total of 6435 square metres at a roof pitch angle of 23 degrees, sloping down too an 8 degree pitch diverting the water to the north side of the roof. When calculating total catchment rain angle must also be taken into account creating a multiplier as shown in table 3.4.3.2 however given the whole roof is sloped with no parallel angles a build‐up of roof water is avoided up to the point of the gutters and thus the gutters must be designed to allow for this to avoid hydraulic pressure build‐up.

ARCT4430 Compliance Report 2

Down pipes around the building are to be located in and along the external columns the amount of which must be calculated by a hydraulic engineer which must be able to cope with a 1in50 year storm. Overflow considerations must also be taken as ultimately if in the case of a 1in500 year rainstorm water MUST be exited from the roof as fast as possible given its scale it could have the possibility to create structural failure. To minimise the spatial demands for drainpipes of such scale it is also recommended that siphonic draining be used. It may even be possible to employ numerous siphons drain in mini eaves throughout the building to help exit the water even faster.

All storm water must further be drained into soak wells beneath the building however it may also be possible to funnel some towards the catchment tanks in the building needed for firefighting provided it passes through a debris filter. Given the volume of water being captured it may also be worth considering a greater capture system solution by diverting the water into the possession of the city council and working with them to use this water to an advantageous and economic use. Possible locations for soak wells as well as the down pipes are outlined in the ground floor plan of the building.

Part F2 SANITARY AND OTHER FACILITIES

Clause F2.2

Comments

As per F2.2 the number of occupants is to be calculated as per D1.13 it is expected a perF2.2b that the facility will be a 50/50 split ,male and female, and F2.3 will be used to calculate sanitary facilities for each sex. As per F1.1 a unisex facility comprises of one wash basin and mean of disposal of sanitary towels.

Therefore as per J1.3 the minimum total R‐value required as per Table J1.3a is upwards of 3.7 As per Table J1.3b given that some services such as sprinklers and roof lighting will be installed within the roof an adjusted R value of 4.7 is given with a .47% loss of ceiling insulation area. .47 was achieved with redesign of roof section moving sprinkler to an area not affecting roof insulation, also allowing for ease of servicing See Section for roof insulation details Given no requirements for lighting outlined in F4 as per J1.4a the roof lights must comply with Table j1.4 Given the very shallow nature of all roof lights installed a light shaft index of Less than 0.5 is universal throughout the building given the formula outlined in Table J1.4 Note 1. Therefore with a total roof area usage of .47% a total system solar heat gain coefficient of not more than 0.83 is given allowing for basic structural glazing to be used.

Given the unique nature of this building theoretically not having any external walls as the entire façade is glazed J1.5 become N/a as per J1.5ii however, this seems somewhat irresponsible to ignore the requirements for internal wall insulation therefore it should be attempted to get the external glazing to an appropriate R value as outlined in Table J1.5a which specifies for climate zone 7, an R value of 2.8 minimum OR a total r value of 1.4 provided the glazing satisfies the energy index option B of Table J2.4a which specifies a minimum of 0.058 for climate zone 7 option B To achieve this R‐ value argon charged triple glazing is to be used however as outlined in J2.4 the current glazing calculations are not compliant therefore an engineering solution is needed

Comments As is very clearly obvious from the attached glazing calculation this building does not currently comply with the glazing requirements for a building of its nature and climate zone. Certain areas are

ARCT4430 Compliance Report 2 compliant however other areas are vastly non‐compliant meaning far to much solar energy is entering and exiting the building even with the specified Triple glazing that has been used. As a result an engineering solution seeking to remedy this energy inefficiency is desired, whether it be an offsetting technique or a thermal engineering technique involving active cooling of façade panels to prevent heat exchange. One important consideration to note however is that this building has been designed to be located in Finland where they experience extremely cold weather, the glazing calculator is an Australian based calculation so it is possible that a much greater level of solar gain would be advantageous, although with results this extreme it still seem likely to be too high at least in the summer and heat loss also being a major concern especially in a gallery which requires highly consistent conditions.

Description

Comments

Y As per J3.1 with a Class 9 building operating in climate zone 7 the Guggenheim is required to comply with the deemed to satisfy points outlined in J. J3.2 N/a No chimneys J3.3 All roof lights used throughout the design must be sealed as per A as they are conditioned spaces, as outlined in B these roof lights are to be sealed with a weather proof seal, in this case triple glazing with moisture and draft seals.

J3.4 A given the hostile climate of Helsinki and art gallery conditions all windows forming a part of the envelope are in operable however must still requires an appropriate seal to restrict air infiltration into the conditioned spaces within.

J3.4c The seals required for A also including the swinging doors on the ground level requires a draft protection devices on the bottom edge of the door swings.

J3.4d All doors on the ground level as well as doors to the roof gallery are further required to be self‐closing given they lead onto a conditioned space.

J3.5 All exhaust fans for the kitchen and bathrooms further require

ARCT4430 Compliance Report 2 a self‐closing damper given they are conditioned spaces.

J3.6 All envelope systems must be sealed, including façade glazing, roof construction and the entrance lobbies. As per J3.6b they must be sealed by either enclosed internal lining systems or caulking skirting or architraves. For the Guggenheim a combination of caulking and enclosed lining systems is used, See section for illustration.

J3.7 N/a evaporative cooling not used.
