PODIUM PARK in Krakow 43 Jana Pawła II Avenue, Krakow

Building standard Finishing standard in the shared areas without office space Podium park complex 1. General features of the facility 1.1 Intended use of the Podium Park Building Complex The Podium Park buildings accommodate office and retail functions.

The complex comprises 3 recurrent tower buildings: A, B and C, with 11 overground storeys each, accommodating office functions on 9 storeys and 2 storeys designed for office and retail functions. In two connectors between the buildings, office and retail functions are planned for both storeys. In the underground part, 3 two-level underground garages have been designed for each of the buildings for the needs of the building users, and technical rooms and warehouses.

In the direct neighborhood of the main cores of the tower buildings, changing rooms and showers for bikers have been designed on the first underground floor.

1.2 Functional plan 1.2.1 Typical floor in the building A typical floor in the tower building is composed of office space, located around the central core, accessible from the elevator lobby.

Three-row building with the axis layout: 8.10/8.40 per 8.10 in the office module 1.35 m, making it possible to divide the space into offices with the minimum axis width of 2.7 m.

1.2.2 Core The core of the tower building accommodates: • the main complex of 6 fast passenger elevators and 1 additional rescue crew elevator, connecting all overground and underground storeys and the elevator lobby, designed symmetrically in relation to the tower outline, with direct entrance to the tenants area; • fire exit staircases with vestibules, accessible from four sides of the building, ensure maximum length of the fire escape up to 40 m with the arrangements and up to 32 m without arrangements;

• the northern vestibule of the staircase offers access to the rescue elevator, which on a daily basis is used as a freight elevator; • the core from the northern and southern side is closed by the main installation shafts.

1.2.3 Ground floor The ground floor of Building A will feature a two-storey, representative lobby zone with the reception from south-west providing access to the elevator lobby, office and retail space to be arranged by future tenants, generally accessible toilets and administrative rooms complex (including security, technical services and BMS room). The reception is connected to the security post. As for retail space, it is planned to locate an open access cafe in each entrance lobby; in building A and C – canteen.

1.2.4 First floor The first floor of the tower buildings is different from the typical storey due to the empty south-west corner, following from the twostorey high entrance lobby. As in a typical floor in the tower building, the first floor is composed of office space for lease, located around the central core, accessible from the elevator lobby.

1.2.5 Second floor The second floor of the tower buildings is different from the typical storey only due to access to the terraces, constituting the roof over the connectors. The terraces are designed on the floor level of floor +2 and then, amphitheater steps will provide access to green roofs which, in addition to hardened surfaces, will be arranged as an attractive green area with diversified greenery and spatial arrangements with different types of functions, attractive to future tenants. As opposed to the courtyards, the terraces on floor +2 will be accessible only to the users of the adjacent offices, and exits will be protected by access control.

Building standard 1.2.6 Underground storeys The main designation of the underground storeys is a garage for the needs of building users. Most spaces have the width of 250 cm and broad passages (measurements on the drawings), allowing for comfortable parking of 3 cars in the construction module (between pillars).

Development of the project site and the nearest surroundings 1.2.7 Transportation system The complex will be accessible equally by public transport, bicycles, passenger cars and taxis, with a short-term parking possibility. Parking spaces for passenger cars have been designed in the site and in the underground garage. In addition, access for fire brigade vehicles, rescue teams (from the west, north and east, and through the fire road in the form of letter U for the middle tower) and driveway for delivery vehicles (from the north) has been ensured. Internal transportation system in the site is connected to the existing and planned road systems in the site and the direct surroundings.

1.2.8 Bicycle paths A bicycle path runs on the northern side of Al. Jana Pawła II, along the southern edge of the site, ensuring safe access to the project site.

1.2.9 MParking spaces The Investment Project comprises construction of overground the following parking spaces: Stage A 22 parking spaces along the western and 19 parking spaces along the southern edge of the project site; in total 41 parking spaces will be built in this stage, including 2 spaces for the disabled and 2 spaces for low-emission cars Stage B 17 parking spaces along the southern edge of the project site, including 2 spaces for the disabled and 2 spaces for low-emission cars

1.2.10 Small architecture elements In the facility there will be bike stands, a self-service bike repair station, gate barriers, and outdoor steps with a ramp protected by a railing in the south-eastern part of the plot. The remaining small architecture elements, including meeting points, benches, etc., will be built in generally accessible courtyards

Building standard 1.2.11 Landscaping and greenery The site, apart from hardened surfaces, will be arranged as an attractive green courtyard space and in the form of green roofs. The generally accessible courtyards are an added value for the offices, generally accessible space, attractive both in the summer and winter.

They are a visual spatial attraction visible from the offices above.

The roofs of the connectors, adapted to serve as terraces and gardens, constitute added value for the offices directly adjacent to them, with exits to the terraces with access-control doors.

The spatial arrangement of the courtyards will allow for, among others, working outside, holding meetings and events, a “summer open-air cinema” and will be a zone for relaxation, rest, having a coffee or eating a meal (external canteen) Construction and material solutions The Podium Park building complex has been designed on the basis of the Investor’s above-the-standard requirements in respect of the utility and technical parameters of the facility and the promotion of sustainable construction and ecofriendly lifestyles. The thermal insulation of dividing walls, doors and windows is better than standard insulation and satisfies at least the guidelines provided for 2021 in the Infrastructure Minister’s Regulation on the technical conditions to be satisfied by buildings and their locations.

The complex has obtained the prestigious BREEAM certificate at the Outstanding level 1.2.12 Building structure The structure of the buildings has been designed as a reinforcedconcrete pillar-and-slab system with two stiffening cores in each of the buildings. The design of the foundation slab provides for a variable thickness of between 60cm and 90cm, with local extra thickness areas under the pillars of up to 120cm. The two-level underground section will be constructed by applying monolithic technology.

The reinforced-concrete diaphragm perimeter walls are designed to have a thickness of 60cm, which coupled with the foundation slab guarantees that the garage will remain watertight – “white bathtub technology”. The primary support structure of the overground section will be a monolithic framework designed as a slab-and-pillar system with stiffening pillars in each section separated by an expansion joint.

The primary pillar grid has been designed as an 8.1m x 8.1m orthogonal grid with local dimensions of 8.4m x 8.1m and 7.8m x 8.1m.

The floor slabs of the overground floors resting on pillars and walls are designed for the most part to have a thickness of 28cm, with the exception of the courtyard slab (35cm with local extra thickness) and the roofing slab has been designed to have a thickness of 32cm.

1.2.13 Permitted loads The principle of permitted loads is depicted in the load diagrams provided in an attachment to the tender and execution design of the structure.

1.2.14 Façades The façade of each of the Podium Park buildings has been designed to satisfy the requirements due to enter into force on 1 January 2021.

To finish the main portion of the façade in a ventilated system, an ALUCOBOND A2 aluminum stud or equivalent system has been designed. The attachment of the studs is hidden, based on a suspension system. The grate is mounted to the wall via thermal consoles to avoid single-point thermal bridges. Facade colors are designed in elegant shades: metallic sand, white and matte graphite.

The glazed portion of the exterior façade of the building will be constructed as a pillar-and-bolt façade (connectors and façades of the ground floor and the entrance lobby) and in a window-and-door system (other glazings). Benchmark manufacturer: Aluprof. Glazing with double-chamber glass sets of improved insulation values.

Building standard 2. Building finishing standard 2.1 Finishing of shared areas The design of interiors of the shared areas has been developed based on the principle of esthetic consistency of all three office towers while emphasizing the individual character of each one of them. The element distinguishing the buildings is the type of precious metal that is used for interior finishing, furniture fit-out and lighting of shared areas.

2.1.1 Flooring Stoneware flooring The building has been designed to be fitted with 30cm x 60cm stoneware tiles and large-format stoneware tiles. The standard of the tiles depends on the intended use of the rooms.

Thin-layer coatings For floor finishing in the garages, driveway slopes, technical rooms and storage rooms, thin-layer coated flooring has been designed.

Doormats Heavy duty doormats – cleaning strips with an aluminum structure and rim – have been designed at the entrances to the building from the outside.

2.1.2 Skirting boards For the finishing of floor edges in shared areas, skirting boards have been designed.

2.1.3 Wall finishing Architectural concrete For the finishing of walls in entrance lobbies and elevator lobbies on overground floors, a concrete cladding has been designed with an underlying system substructure attached to reinforced concrete walls. The texture of the cladding is similar to that of architectural concrete – tiles with a natural surface and a small number of miniature etched holes (up to 3mm) and esthetically pleasing slight discolorations. The attachment of the cladding is hidden. Graphite and sand-colored smooth cladding tiles and sand-colored rough corrugated tiles have been designed, cast using a Reckli Thur 1/173 stencil.

Plasters Internal walls are designed to be finished with plasters adapted to the intended use of the room, the type of underlying material and the top finishing layer.

Paints For the finishing of the walls, it is proposed to apply several types of paint coatings, depending on the type of room, the humidity level, etc.

2.1.4 Ceiling finishing For the finishing of ceilings in the representation areas, various types of suspended ceilings have been designed, depending on the standard of the room and other requirements (including HVAC considerations for the extraction of smoke from traffic routes).

2.1.5 Decorative elements In the entrance lobby of Building A, a green wall has been designed covered in living plants.

In the entrance lobby of Building B, a water wall has been designed as a ‘rain curtain’ solution. Water flowing down steel cables will create a friendly microclimate of the interior without causing any nuisance associated with noise or splashes of water. In the entrance lobby of Building C, an ‘interactive wall’ has been designed.

Project summary General information about external and internal electricity and telecommunication infrastructure PODIUM PARK is ready to host, serve and support corporations with their own server farms as well as providers of outsourcing services.

1. Electricity supply to each of the three Podium Park buildings.

1.1 Safety of electricity supply from the 15kV municipal grid.

The electrical substation which supplies electricity to the Podium Park buildings is fed from two independent 110kV power lines.

In turn, the buildings themselves are fed from two independent 15kV cable lines directly from the 110kV/15kV substation.

The routes of the electricity supply lines feeding the Podium Park buildings have been designed to enter the facilities from two different directions in order to prevent a simultaneous damage to the primary and backup power supply sources.

1.2 Redundant electricity supply to the facility. High level of security of the primary and backup power supply systems.

For each building, two transformers of 2000kVA each have been provided.

Should any one of these transformers or any one of the supply lines be damaged, the undamaged transformer will take over 100% of the load.

In the event of a loss of power supply from the municipal grid, practically all the load will be taken over by the two power generators.

On the roof of each of the Podium Park buildings, space is provided for 2 power generators (to be purchased from a recognized manufacturer) of 700kVA each, ensuring a minimum of 15 hours of simultaneous operation of both generators (thus securing the supply of power to the facility) without the need to provide any additional fuel from external sources. The supply of fuel from external sources will understandably extend the operational time of the generators.

An estimated duration of emergency operation at 100% of the load for each generator is up to 500h per year.

Continuous operation (in excess of 500h per year) is possible for variable capacity below 635kVA, with an overload capacity of 10% for 1h per 12h of operation.

The designer has consulted and verified with a technical expert the method of installation of the power generators on the roof of each of the three buildings.

Note: In principle, it is possible to install 2 emergency (backup) generators with a capacity greater than 700 kVA, yet such a solution would require verification and approval by the constructor and technical designers.

1.3 Electricity supply safety level in the event of a concurrent failure of two power supply routes from the municipal grid.

It is possible to fit two power generators with an emergency (backup) capacity of 700kVA each (635kVA of continuous capacity) on the roof of each of the Podium Park buildings.

In the shell & core state, a complete fuel supply installation will be prepared for 2 power generators in a casing and ample room will be secured in technical shafts for additional cables and busbars.

1.4 Uninterruptible power supply safety level.

On the basement level, directly under the transformer substation, it is possible to place uninterruptible power supply (UPS) devices with a capacity of up to 700kVA (2 x 350kVA) and 20-minute batteries at the expense of single parking spaces on level -2 in the underground section of each of the buildings.

(Confidential information)

Project summary 2. Distribution of electricity supply The transformer substation is located in a safe spot in each of the Podium Park buildings, in an area which is not subject to the risk of flooding, separated by a firewall from the other parts of the building.

In each of the buildings, two vertical shafts have been provided.

In each shaft, reserve space is provided for additional cable lines and a busbar for currents of up to 1250A (adapted to the anticipated 700kVA generators).

3. Monitoring of electricity supply In each of the Podium Park buildings, 15kV switchgear, 0.4kV switchgear, all main power outflow and critical elements are monitored by a building management system (BMS).

In each of the buildings, continuous technical supervision is scheduled to be implemented.

4. Integration of security systems In each of the Podium Park office buildings, full integration of the following four security systems (the first building in Kraków to provide this functionality) has been envisaged: • access control system, • closed circuit television system (CCTV), • burglary and robbery alarm system, • fire alarm system.

5. Access control In each of the buildings, anti-passback access control has been implemented. The system and organization of traffic prevent unauthorized access to office floors (including those occupied by corporations).

It is also possible to enhance the system so that it secures 100% effectiveness against unauthorized access by outsiders (including those entering the facility via the underground garage zone).

The enhancement would involve advanced analytics of images obtained from CCTV cameras (cost of this option to be covered by the tenant if this criterion must be satisfied).

A buffer zone has been designed in the building, separating the free-access zone from the office zone, including the portion occupied by corporations.

It would be enough to enhance the system by adding analytics of camera images in all buffer zones.

The system operates based on the principle of analyzing the number of persons entering the buffer zone and comparing it with the number of ‘card punches’.

If a difference is detected, security services will be notified and a message will be sounded via the loudspeakers that the authorization of all persons concerned is required.

The card of the person who has allowed access to the outsider will also be automatically locked and will enable the leaving of the elevator only on the ground floor level.

This solution will prevent persons holding an authorization card from allowing access to unauthorized outsiders, for instance through the garage level entrance.

6. Telecommunication feeds Each of the buildings is fed from 2 independent cable lines (2 telecommunication channeling routes). The routes of the telecommunication lines feeding the Podium Park buildings have been designed to enter the facilities from two different directions in order to prevent a simultaneous damage to the telecommunication feed sources.

Project summary General information about the possibility of local reinforcement of the structure of the Podium Park buildings to host, serve and support corporations with their own server farms as well as providers of outsourcing services.

It is technically possible to increase locally the weight of the equipment to be installed on the roof and increase the load of the repetitive floor zones in the Podium Park buildings from 5kN per square meter to 10kN per square meter.

1.Local increase in the weight of the equipment to be installed on the roof After obtaining a map depicting the planned locations of the various pieces of equipment to be installed on the roof along with their weights, the building structure designer will verify the value of the local load on the roof. If the values assumed in the design are exceeded, it will be necessary to analyze and select appropriate roof reinforcements using composite tapes attached to the bottom surface of the roof.

2.Local increase in the load of the repetitive floor zones from 5kN per square meter to 10kN per square meter In this respect, it is necessary to specify the extent of the change and perform a detailed analysis because, depending on the extent, we may have to deal with the following situations: 2.1 Load increase (extent involving 1 or 2 floors) It would be necessary to assume the need to reinforce floor slabs with steel heads at the pillars and composite tapes on the bottom surface of the roof in the increased load area.

2.2 Load increase (extent involving a greater number of floors) In addition to the requirement to reinforce each floor slab in accordance with item 1, it may be necessary to reinforce the pillars and the foundation slab (in the case of the latter element, a higher expenditure would be involved).

Note: Detailed guidelines may be provided after defining the extent of changes, carrying out a detailed analysis and updating the calculation model.

Optional prices of reinforcement with composite tapes may be discussed with any manufacturer, for instance S&P Polska.

Project summary General information about heating, cooling and ventilation systems and guidelines regarding control and measurement instruments and the building management system 1. VRV heat recovery-enabled heating and cooling systems (heating and cooling of lease zones) The cooling and heating of office and commercial spaces is designed on the basis of a Daikin heat recovery-enabled 3-pipe VRV system.

The system operates on the principle of direct evaporation-based variable volume of a cooling agent that enables cooling or heating by a single cooling system (via a heat pump). The system consists of outdoor units installed on the roof and indoor units. The use of internal channel units and coffered units is assumed.

Temperature control in distinct rooms/zones will be effected using local wired wall-mounted thermostats. In addition to separate control units for distinct rooms/zones, a central control system is designed for VRV systems installed in the facility using an Intelligent Manager BMS station. The central control system enables device management, optimization of electricity consumption in the building and settlement of electricity consumption between individual receiving units. A meter distributes the volume of consumed electricity among the users.

In the guidelines for control and measurement instruments, BMS functionalities have been defined for monitoring and archiving temperature trends and a function has been envisaged providing for the possibility of defining regressions (limits) of temperature setpoints from the position of local controllers.

At the shell and core stage, the design provides for the completion of all works related to the installation of VRV equipment on the roof and in the shafts with installation terminals on the floors and the completion of all works for the administration and traffic zones.

In respect the floors earmarked for the lease of premises, VRV equipment will be installed based on detailed arrangements following from layout designs for individual tenants, starting from the place of entry of freon systems from the technical shafts on the given floor

. In the case of split air conditioners for potential server rooms of the tenants (applicable to piping for two air conditioners per floor, for the capacity assumed in the multi-discipline concept), in the shell and core state piping routes will be run in the technical shafts with an inlet on the roof in the zone of a future condensing unit and an outlet on the given floor from the technical shaft to the leased area. A specific air conditioner in the server room should be selected in consultation with the designer.

2. Individual cooling systems For technical rooms, for instance transformer rooms and server rooms, individual split air conditioners will be used. Each of these air conditioners should be included in the BMS monitoring system.

Moreover, as part of the solution for the core of the building, shaft space has been reserved with control access from the corridor level on each floor for additional freon shafts for individual server rooms on the tenants’ floors as well as space on the roof space and in the garage floor zone for the installation of the split air conditioners.

At the shell and core stage, no fewer than 2 freon routes have been designed for each office floor (the detailed quantity is shown in the drawing presenting a diagram of freon installations). The ultimate selection and installation of split air conditioners for the tenants will be based on the tenants’ layout documentation. The assumptions provide for the possibility of ensuring redundancies for the tenant server rooms through units included in the VRV systems dedicated to specific floors.

3. Chilled water system (cooling of ventilation air) For the purposes of feeding glycol coolers of individual ventilation units, the design envisages the application of a cascade of two Daikin chilled water units: EWAQ580F-XR and EWAQ500F-XR. The units will be installed on the roof of the high building. The chilled water technology requires the operation of each unit with a hydraulic pump module fitted with a safety valve.

Project summary 4. Building control and measurement instruments, BMS and utility metering for heating and cooling systems A detailed execution design has been prepared for the building control and measurement instruments, BMS and metering of utilities, taking into account the guidelines prepared for the BMS and control and measurement instruments by technical designers, including the designers of sanitary installations. The said execution design includes the following elements, among others: • Guidelines for control and measurement instruments and the BMS in respect of VRV freon heating and cooling systems: • Guidelines for control and measurement instruments and the BMS in respect of split freon air conditioners (DX): • Guidelines for control and measurement instruments and the BMS in respect of chilled water units: • Guidelines for control and measurement instruments and the BMS in respect of chilled water systems: • Guidelines for the BMS and control and measurement instruments in respect of air curtains: 5. Instalacje wentylacji mechanicznej 1.1 Installation of mechanical ventilation in residential areas 1.1.1 Ventilation of office floors The necessary volume of external air to the office floor area and the lobby area on the ground floor of the building will be provided via a set of two Swegon sectional roof-mounted ventilation control units.

The following capacities of the ventilation control units have been envisaged: • AHU-A-WM-NB1WB1 system → 53,500.0 [m3/h] • AHU-A-WM-NB2WB2 system → 52,000.0 [m3/h] 1.1.2 Ventilation of restrooms on the office floors The necessary volume of external air to the restroom area on the office floors and the free-access restrooms on the ground floor will be provided via a set of two Frapol sectional roof-mounted supply-andexhaust ventilation control units. The following capacities of the ventilation control units have been envisaged:

• AHU-A-WM-WC1 system → 6,600.0 [m3/h] • AHU-A-WM-WC2 system → 6,600.0 [m3/h] 1.1.3 Ventilation of employee amenity rooms on the office floors The necessary volume of external air to the employee amenity room area on the office floors and the coffee point area on the ground floor will be provided via a set of two Frapol sectional roof-mounted supply-and-exhaust ventilation control units. The following capacities of the ventilation control units have been envisaged: • AHU-A-WM-NS1WS1 system → 3,000.0 [m3/h] • AHU-A-WM-NS2WS2 system → 3,800.0 [m3/h] 1.1.4 Smoke protection system The building is classified as a high building and for this reason all emergency escape staircases and fire vestibules will be fitted with anti-smoke solutions by maintaining overpressure in these areas and, if a door is opened, by ensuring an appropriate rate of airflow.

The anti-smoke solutions applied in horizontal emergency escape routes include smoke extraction installations coupled with overpressure staircase and vestibule systems.

1.2 Ventilation systems applied in the lease zone The ventilation system solution applied in the office space lease area is presented in detail in the “Execution design of a sample layout of fit-out area 1521_PPW_FIT”.
