2 CURRENT STATE

2.1 Location and existing structures

The building plot is situated on the northwest pier of the port territory of Tallinn. West of the planned area features Linnahall (City Hall) and southeast from the area features port area with berths no. 12 to 17. Other sides of the area border with the sea. Northwest side of the pier has only berths no. 24 to 27. Temporary structures situated in the design area will be removed.

2.2 Requirements for heritage conservation

The building design documentation has been presented to the Tallinn Culture and Heritage Department and it has been compiled in accordance with their suggestions.

Historical wall on the northwest pier will be preserved. The wall is covered to full extent with new concrete protective layer, but it is still an attractive object in terms of its shape, trajectory of which follows the shape of the historical North Pier. In order to emphasise the wall as an important landmark and to highlight it in the open urban space, the promenade that follows the northwest pier is lifted on top of the wall. The walkway on top of the wall has minimum width in order to cover the roughness of the wall radius, while not concealing the wall.

According to the data of the Culture and Heritage Department, some of the wall sections date back to more recent times by replacing the demolished historical wall sections with concrete. The wall surface with historical value is exposed in its entirety. New steps and openings are intended only in the places where the shape does not coincide with the original defensive structure. Added steps allow moving down from the wall to the ground level, where its northwest side is made accessible and observable for citizens. Design documentation also prescribes elimination of all roughness in the said area in order to allow exhibiting the wall at maximum height.

At the end of the promenade will be exhibited a model of the historical appearance of the North Pier.

3 GENERAL ARCHITECTURAL SOLUTION

3.1 Location of the building and structures

Intended location of the cruise terminal is in the northern part of northwest pier between berths no. 25 and 26. The park with roof promenade open to urban space reaches until the end of northwest pier.

Existing temporary kiosks are removed. The existing historical defensive wall at the end of the northwest pier is preserved and it will be used as a base for roof-level promenade.

3.2 Construction stages

The designed cruise terminal can be built in two stages:








• Cruise terminal building with the roof-level promenade reaching berths no. 26 and 27. • Roof-level promenade from berths no. 26 and 27 to the end of northwest pier.

3.3 Overall concept of the building architecture

Cruise terminal is the calling card of the Port of Tallinn. The purpose is to establish a simple and functional pavilion and improved north edge of the northwest pier.

Above low cruise terminal is a promenade, crossing it from Logi Street to the end of the northwest pier. The entrance to the area is divided into two. Entrance to the terminal and exit to Tallinn runs through the park. Citizens are directed towards the light traffic road on top of the terminal.

Pavilion and the berth in front of it have fenced recreational area for tourists (ISPS area). The roof of the building will feature light traffic road promenade with benches, small squares and shelters for walkers and persons practicing recreational sports.

In view of seasonal use of the cruise terminal, the efficiency of the building is intended to be improved by all-year-round use. This is enabled by the light traffic road crossing above the building, which brings the citizens to the northwest pier. In winter, the waiting areas of the pavilion can be used for holding exhibitions, fairs or concerts. Tallinn resident, who is accustomed to the café and restaurant located in the terminal area all-year-round near the light traffic road, will also come here in winter, when events are organised in the terminal to increase the attraction of the area.

Terminal building has a simple interior structure. Adjacent to the seaside with berths 24 to 27, there is passenger waiting area, which can be divided in two by means of mobile passport control cabins for performing border check procedures.

Cruise tourist who does not want to visit the city can spend time in the catering facility or on the roof, in public city park, which is open to all citizens.

The two zones of the terminal building have a festive elevated roof. Larger opening is situated above potential concert area and smaller opening gives an opportunity to bring the cafe and restaurant functions higher, to the promenade level. Larger opening is directed to the north, constituting an area with 25-degree angle for placing solar panels. Cafe is facing towards the south, the Old Town. The volumes protruding from the roof of low terminal form windless zones in the city park.

Next to the building’s wall adjacent to the parking area are located premises for ancillary and service areas. The second floor of this building section also accommodates technical rooms.

The solution for the end of northwest pier utilises the nifty arched wall. Promenade continues smoothly on top of the wall. Seating is planned near the promenade on the wall. The northern landscape of the wall has smooth connection to the promenade via two wide staircases. Large staircases from the wall are planned wide, in order to create the audience space for the events taking place in the park. At the end of the promenade, there is exhibited the model of former defence works of the Port of Tallinn. To the southern side of the wall, green areas with evergreen trees is planned, which will in the future reduce the windiness of the park. The tourists from the third cruise berth move to the terminal under elevated promenade that provides








protection from rain. The promenade side facing the city is solved by greenery. City park can be closed for night and fenced off from the berths level.

Conceptual idea of exterior lighting is described in the explanatory report of outdoor space.

3.4 Energy efficiency and indoor climate

See the HVAC section of the building design documentation.

3.5 Premises

The building complex of the cruise terminal is divided into three sections:

• Cruise terminal with service premises. • Restaurant with service premises. • The guard room at the main entrance, along with ancillary premises (waste room and

maintenance equipment).

Cruise terminal building has been designed for simultaneous use for cruise tourists and citizens. Thus, the spatial layout of the building is designed so that their paths would not cross and there would not be uncontrolled movement from one zone to another.

The ISPS area (International Ship and Port Facility Security) intended for cruise tourists only is located on the first floor. They are serviced by a large, three-storey high open terminal room at the cruise berths’ side.

Terminal design provides for 8 passport control stations for simultaneous servicing of the cruise tourists. For turnover of 10,000 people within 2h, maximum time spent on one person is 5.76 seconds. During off-season period, the passport control booths can be moved to the storage.

Near the passport control cabins, there is a closed customs and border guard observation and inspection room with large windows facing the terminal room to the full extent of the room. They have safety glass and can only be seen through from the observation and inspection room side. Next to the latter is also the workroom of customs and border guard officials.

Technical and ancillary premises of the building are gathered on the first and the second floor of the side facing the bus parking area. Restaurant is planned on the third floor and is open to the citizens who can access it from the promenade on the roof level.

Entire building layout allows changing the size of areas for cruise tourists ISPS and the areas open to citizens according to need. Terminal space can be divided into two separately used areas by means of sliding walls.

During the off-season period, the entire building can be used for organising events. Terminal space allows organising concerts with sound reinforcement. At that time, the access to the building can be ensured so that the visitors would not reach berths 24…27.

Layout of rooms is indicated on floor plans, see drawings AR-5-01…AR-5-03.

Calculated maximum capacity of the building is 1,985 people, who are divided in the building as follows:








• 1st floor – 1,830 people (calculated by 1person per 1m²) • 2nd floor – 35 people • 3rd floor – 120 people

3.6 Movement options for people with reduced mobility, visually or hearing impaired

persons

The building can be entered from all the doors on the first floor, the height of the floor at the entrances is at the same level as sidewalk. Doorsills are not higher than 20mm from the floor level. The building design prescribes an elevator for moving between different floors. The surface of elevator controls is in relief or with braille and the elevators use voice notification of floors.

• Glass doors are intended to have safety glass. In case of full glass doors, the glass surface shall be prominently marked.

• Free passageway of all interior doors is min 800mm. • Passages for persons with reduced mobility shall be equipped with direction signs. • Passages not available for persons with reduced mobility shall be equipped with relevant

marking.

The building design includes three toilets intended for persons with reduced mobility. One of them, at the restaurant on the third floor, is located on the first floor, and it can be accessed by elevator.

The requirements for toilets for disabled:

• Toilet for disabled must have enough room to turn the wheelchair, diameter of at least 1,400 mm.

• Required height of the closet 47-50 cm to the toilet seat, placed with the flush tank against the wall (if the toilet is smaller than 2,200x2,500 mm).

• Outwards opening door with wheelchair indication. • Additional handle on the door (placement at the door handle height on the toilet side of

the door and horizontally at the hinges side, length 40-60 cm, height 75-85 cm, bent metal pipe).

• Regular lever tap is used for washing hands instead of photocell mixing tap. • Required wash basin dimensions are ca 550 mm × 400 mm, height from the floor is ca

800 mm. • Thermostatic hand shower with flexible hose must be available for use while sitting on

the closet (bidet shower). • The armrests facilitating the use of the toilet seat must be located on both sides of the

seat at 600 mm interval, (elevated) and adjustable, height to the top of armrest 800 mm. • Toilets for the disabled are equipped with alarm, the alarm or its extension cord must be

accessible both while seated or from the floor. • Recommended placement of the alarm beneath the ceiling above the toilet seat so that

the extension cord would hang next to the toilet seat. • Toilet paper holder within the reach, at 30 cm, or attached to the armrests. • Required height of the mirror from the ground (lower edge of the mirror 900 mm from

the floor), also soap dispensers, paper towel holders, and other wall-mounted fittings.








• The height of hooks from the ground (2–3 hooks for clothes, crutches, walking sticks, etc. will be mounted on the wall next to the closet, at the height of ca 1,200mm from the floor).

• Toilet for the disabled can be locked from inside by using hand-wheels.

4 STRUCTURES OF BUILDING AND SURFACE COVERS

Separate elevator has been intended for transporting dishes between the kitchen and restaurant. Elevator car width is 600 mm, depth is 600 mm.

7 ACOUSTICS

7.1 General information

7.1.1 Scope of design work

This present chapter concerns the acoustics part of the preliminary building design documentation of the Cruise Terminal of the Old City Harbour of Tallinn and it describes the requirements for sound insulation and acoustics of premises. According to the terms of reference of the design work, it concerns cruise terminal and its service premises; main floor of the terminal foresees an opportunity to organise amplified concerts.

7.1.2 Source documents

7.1.2.1 Primary data








• See clause 1.3.1 of the explanatory report

7.1.2.2 Normative documents

• See clause 1.3.3 of the explanatory report

7.2 Environmental noise and vibration levels

The extent of external noise in the near vicinity of the building has not been foreseen in the stage of preliminary building design; approximate noise level is currently Lpeq,A = 62-65 dB. These data will be specified after becoming aware of the planned traffic density in near vicinity of the building and other potential external sources of noise. There are no known sources of vibration in the near vicinity of the building. Environmental noise and vibration are not expected to cause any problems.

7.3 Sound insulation requirements for exterior enclosure

Sound insulation of exterior enclosure is chosen so that the noise in the rooms would not exceed permitted levels according to standard EVS 842:2003. Based on permitted traffic noise levels in service premises and restaurant and café, there are no increased requirements for sound insulation for exterior enclosure. The sound insulation requirement for exterior enclosure and windows of the offices on the 2nd floor is R’tr,s,w = 30 dB, which is ensured by usual building structures. Attention should be paid to sound insulation of the exterior enclosure in case the concert venue designed for the main floor of the cruise terminal is seen as multi-purpose hall, where permitted noise level must not exceed LpAmax = 30 dB. Provided that the maximum noise level caused by passenger cars in near vicinity of the building is LpAmax = 70 dB, the sound insulation requirements for the exterior enclosure of the multi-purpose hall must be around R’tr,s,w = 40 dB (incl. exterior doors). These requirements must be specified in the next stage of the design documentation in case the customer deems it necessary to treat the intended concert venue as a multi-purpose hall. Norms apply also to the noise caused by the noise-generating equipment or other noisy activities reaching to the outdoor enclosure of the building. Pursuant to the Regulation no. 71 of the Minister of Environment, the sound pressure level caused by operation of utility equipment or other noise-generating activity in the territory of public buildings during daytime exceed 55 dBA. Based on that requirement, the sound insulation requirement of the external wall an doors of the cruise terminal hall is at least R’tr,s,w = 40 dB.

External wall of the ventilation room is made of 250 mm thick sandwich panel (sheet metal + thermal insulation + sheet metal); sound insulation of the structure is unknown. Based on the preliminary building design solution, the noise level in ventilation room does not exceed LpA = 70 dB; the noise caused by utility equipment in immediate vicinity of the building does not exceed 55 dBA. Minimum sound insulation requirement for the external wall of the ventilation room is R’w = 20 dB, which is ensured by the structure chosen for the design if high-density wool sheet is used as insulation material and the thickness of sheet metal is maximum possible thickness used in analogous sandwich panels.

Noise caused by the operation of utility equipment reaches the outdoor enclosure of the building at the boiler room. As of now, the noise levels of the boiler room are not known, and thus it is difficult to set detailed requirements for sound insulation. In the stage of preliminary








building design, the sound insulation requirement for external wall and door of the boiler room is R’w = 40 dB, which will be further specified in the next stage of the design.

The structures of exterior enclosure are described in the architectural and buildings structures part of the building design documentation.

7.4 Sound insulation requirements between rooms

7.4.1 Sound insulation of internal walls. Doors and sliding walls

7.4.1.1 Premises on the 1st floor

There are no increased sound insulation requirements for the internal walls of the premises on the first floor, except for the boiler room with noise-generating equipment. As of now, the noise level of the boiler room is not known. The wall adjacent to the hall of the cruise terminal will be made of 190 mm thick hollow-core slab. Considering that the boiler room is adjacent to the intended concert venue, the hollow cores of the wall slabs must be filled core slabs. Estimated sound insulation of the filled wall is R’w = 55 dB. This is sufficient in case the noise level in the boiler room does not exceed LpA = 70 dB. In case of increased noise level, the internal walls of the boiler room must be equipped with sound insulating shuttering made of double plasterboard. The sound insulation requirement for the sliding walls of the first floor is Rw = 55 dB (under construction conditions R’w = 53 dB). Considering that noise requirement are established for the concert venue, the sound insulation of the doors of stairwells must be R’w = 35 dB (under laboratory conditions Rw = 38 dB).

7.4.1.2 Premises on the 2nd floor

On the second floor, sound insulation requirement has been established for the walls of ventilation room adjacent to the concert area and stairwell. The walls are designed to be made of 190 mm thick hollow-core slab that has to be filled. Estimated sound insulation of the filled wall is R’w = 55 dB, which is sufficient, because the noise level in the ventilation room according to the equipment chosen in the preliminary building design is lower than LpA = 70 dB. The sound insulation requirement for the doors of the ventilation room is R’w = 38 dB (under laboratory conditions Rw = 41dB), considering the noise limits for concert venue. The sound insulation requirement for the doors of the stairwell is R’w = 35 dB (under laboratory conditions Rw = 38 dB); requirement is established for both doors individually.

7.4.2 Sound insulation of floors

The floor of the ventilation room is designed to be made of 220 mm thick hollow-core slab with 60 mm thick cast-in coating. Estimated insulation of airborne sound of the structure is within the range of R’w = 52 dB, which is sufficient if the noise level in the ventilation room does not exceed LpA = 70 dB (below that according to the data of preliminary building design). As the structural solution of the floor does not include floating floor, special attention must be paid to








the vibration insulation of equipment. The equipment must be placed on dimensioned vibration bases, which must be taken into account already in the stage of preliminary building design. For the purposes of reducing the vibration of the equipment, when ordering the equipment, the factory manufacturing the equipment should be requested to install inside the case of the unit more efficient dampers than those usually used.

Reduction of footfall from the restaurant on the 3rd floor must ensure that the sound impact level from these premises would not exceed L’nw = 63 dB. Sound impact insulation must be provided by floor design, where one possible version involves use of carpeting on the restaurant floor. Carpeting must reduce the sound impact level by at least ∆Lnw = 11-12 dB. If these premises will have parquet flooring or other floor covering, the floor structure must utilise a layer of elastic material that reduces the footfall within the range of ∆Lnw = 11-12 dB.

7.5 Principles of acoustics solutions of the room

A sound class materials must be used in all sound absorbing suspended ceilings and shuttering (i.e. they belong to the category of acoustic materials with the highest sound absorption, divided into sound classes A-E).

Note. In case sound absorbing suspended ceiling is not intended for any of the premises mentioned below, the sound absorbing slabs shall be attached directly to the ceiling; the thickness of the sound absorbing slab must be at least 40 mm. In case the sound absorbing ceiling panels are mostly covered by ventilation ducts from beneath, it must be noted that it reduces the sound absorbing properties of the ceiling.

The types, quantities and methods of installation of all sound absorbing materials shall be

specified in the main design stage when preparing interior architectural design in

cooperation with acoustics expert.

7.5.1 Concert area (large hall of the cruise terminal)

As the concert area is used for organising events with amplified sound, the objective is to reduce the reverberation of the room to the value that allows amplification without excessive sonority of the room causing problems. Even when using the room as terminal hall, it is beneficial to have the lowest possible reverberation, as it reduces background noise.

In the stage of preliminary building design, the interior finishing of the large hall of the cruise terminal includes the following materials: concrete floor; wall with wooden ribs with sound absorbing slab behind them; slanted ceiling area with wooden ribs with sound absorbing slab behind them; glass surfaces. Design of sound absorbing surface takes into consideration that wooden rib must allow passing of sound (optimally open to the extent of 50%); the thickness of wool slab behind the wooden rib must be 50 mm and the slab must belong to sound absorbing class A (e.g. glass wool sheets Ecophon TAL Industry Modus). Based on calculations, such interior finishing ensures the reverberation on average sound frequencies (500-1000 Hz) T = 1.68 s, which can be considered acceptable in case of such a large room. Additional sound absorbing factor is the audience, e.g. reverberation is reduced to T = 1.45 s in case of audience of 500 people.








7.5.2 Other premises

7.5.2.1 1st floor

Business premises, currency exchange room, border guard room and catering room on the 1st floor will have sound absorbing module suspended ceiling (e.g. Ecophon Master panels).

7.5.2.2 2nd floor

Offices and the recreational room of the restaurant kitchen on the 2nd floor will have sound absorbing module suspended ceiling (e.g. Ecophon Master panels).

7.5.2.3 3rd floor

The restaurant on the 3rd floor will have a ribbed ceiling like in the large hall (with wool sheets at the back).

7.5.2.4 Stairwells

Stairwell ceilings will have acoustic plaster.

7.6 Noise level of utility equipment in the premises and in the territory

7.6.1 Large hall of the cruise terminal

It is reasonable to establish the permitted noise levels of utility equipment based on the requirements for multi-purpose hall. Pursuant to the requirements of standard EVS 842:2003, maximum noise level permitted in multifunctional halls is LpAmax = 30 dB with relevant noise estimation curve NR-25. Permitted noise level means total noise caused by utility equipment and other sources of sound, and thus estimation of every individual source of noise and design of utility equipment or systems should take into account noise level that is somewhat (at least 3-4 dB) lower than aggregate noise level. In case only the noise requirements for service room, i.e. terminal hall, are considered, the permitted noise level is LpAmax = 40 dB, which is too high for concert venue.

7.6.2 Restaurant

Permitted noise level of utility equipment is LpAmax = 40 dB.

7.6.3 Offices and equivalent premises

Permitted noise level in work offices and equivalent premises is LpAmax = 35 dB.

Permitted noise levels in all other premises correspond to standard EVS 842:2003.

Noise levels caused by utility equipment in the outdoor enclosure of the building (e.g. air intake or air extraction) in the area of public traffic shall not exceed LpAmax = 50 dB. The noise level transmitted to outdoor enclosure through the light wall of ventilation chamber must be within the same range.
