PRIMARY NOTES

1. Rules of adaptation.

This ready-to-use engineering specification is distributed under public licenseagreement allowing free use, copy and change for non-profit reasons, including buildingpermit.

Commercial use requires a permit issued by desing office: "ObserwatoriaAstronomiczne, ScopeDome sky observatory ", ul. Jaśminowa 29, 76-200 Słupsk,kom.: +48 602136289, tel.:+48 59 8410191, www.scopedome.com.

In most situations this projects requires to be adapted to local conditions as well as to locallaw regulations.

2. Allowed changes.

Any design engineer is allowed to prepare mirror version of this design as well as tointroduce following changes, without asking for an author permit:

• change of foundations or ground floor level• floor height• stairs or other communication fittings• ceiling type• wall structure • colors and finish• installations• change of windows or doors

TECHNICAL CHARACTERISTICS

3. Subject of elaboration.

Hereby engineering specification contains a construction design for a small astronomicalobservatory building.

4. Site conditions.

Water table is assumed to be below foundation level and the grounds at foundation basehave supportive ability. Assumed base compression (base failure) is 150 kPa.Foundation level at 1,0 m below field level around the building. The foundation shall beadapted to local conditions considering water table and ground sustainability.

5. General description.

The building performs technical function, in a form of a tower base supporting anastronomical dome. Observatory is served remotely and automatically. Technical room is placed at ground floor level,containing peripheral fix-up of the telescope. The interior of cupola constitutes realobservatory. Access on level of cupola through internal stairs (timber or steel one, folding ).Object is meant for individual use, it does not require constant staff.

4. Basic data.

Surface of building: 9,10 m2

Usable area of building: 7,0 m2

Gross floor area: 18,2 m2

Cubature: 28,4 m3

6. General structure characteristics.

Designed building is one-storeyed, with no basement, in a form of rounded tower. It hasmasonry structure. The walls carry precast 3,0m diameter astrodome, made of synthetics(manufactured by ScopeDome).The foundation consists of reinforced concrete strips, 30 cm high and 40cm wide,reinforcement is 4#12, and Ø6 each 30cm. The structure of reinforced concrete columnbase - according to drawing descriptions.Designed foundation walls structure made of concrete blocks, width 24cm, with outerstyrofoam insulation panels, 5-8 cm thick. The walls above the ground masonry made ofaerated concrete blocks, with outer styrofoam insulation panels, 10 cm thick, coated withthin external plaster. Pier column and pier foundation 60x60cm and 40x40cm made of reinforced concrete,reinforcement #12, according to drawing descriptions. The lintels made of poured concrete. The ceiling construction: beam-framed floor, madeof wooden beams 8x16 cm. The stairs are ladder-type or folded, made of wood or steel.

7. Finish.

Internal coatings of calcium-cement plaster. The ceiling – is an open floor with undersidefinished with flaxboard, chipboard or plywood. The ceiling can also be insulated inside andfinished with PCV panels. It is not recommended to use gypsum plates as any coatings.The floors made of anty-glide tiles. Windowsills, sheet facings made of coated tinplates, light gray or light blue colors.

8. Coloring.

External walls coated with external plaster (eg. silica), sand or ivory color. Wall plinth and wall fragments coated with roughcast, gray or beige color. Woodwork – designed window openings filled with glass-block, blue-gray or transparent.Door made of PCV or aluminum, thermally insulated, white.

9. Protections.

Steel elements shall be protected against rust – cleared and then painted 2-3 x with anticorrosive paint and primary ground, if necessary. Protection of wood elements –impregnate with complex chemical preparation against fire, fungi and insects. 10. Thermal and humidity characteristics.

The building has simple structure. It was assumed to be locate in I climate zone (Mid andEastern Europe area). The objects has no permanent heating system, but can beequipped in an optional emergency electrical heater (for electronic devices protectionagainst low temperatures and frost).Thermal penetrability coefficient is 0,29 W/K*m2 for walls and 0,50 W/K*m2 for non-insulated ceiling.

5

11. Installations

Ventilation by gravity – air flow through stairs and astrodome. Electric energy supply frommain electric connection outside the building. Rainfall onto field outside the building. Theobject does not require any sanitary fittings.

11.1. Energy supply cable 0,4kV.The observatory is to be supplied from a cable line, its parameters shall be adapted tothe distance from main power supply connection outside the observatory.

11.2. Control panel.Control panel TG placed as on drawing no E-03. Control panel equipment based on TH-35rail (e.g. HAGER). The panel shall be mounted in a niche inside the wall, with upper sideat 1,8 m over the floor. Fittings according to scheme no E-01.

11.3. Lights, outlets 230 V and 400 V.Internal electrical installations by YDY cable placed under plaster. Sockets placed on acentral pier column shall be mounted at the column surface.

11.4. Anti-shock protection.All installations are equipped with electric shock protection. Additional protection supportsautomatic disconnection system. The system consists of differential switches Idn=0,03Aand excess switches. The receiving installation is based on TN-S pattern. All one-phase outlets/sockets shall bebipolar and have protective bolt.

The main equalizing rail shall be placed close to control panel TG. The rail shall beconnected to observatory equipment made of metal, which normally are not under voltage.Equalizing cables made of copper LY10mm2 w RVS 18 p/t. Main rod shall be grounded.

11.5. Lightning rod installation.The necessity of installing a lightning conductor depends upon local conditions and shallbe determined by an electrician. Electric installation shall be shielded as a protection incase of thunder.

11.6. Calculations.
