Project: Construction of bioclimatic 110 m2 detached residence, attic and solar panels Specifications and technical description January 2015 Company Profile
Arzumanidis Construction is engaged in the study, design and construction of
metal & massive building and environmentally sustainable growth projects.
Our experienced engineers cover all fields and offer integrated solutions for
the construction of modern and innovative bioclimatic residences. Our primary
goals are safety, functionality, resilience and style of each building project.
Furthermore, Arzumanidis Construction specialises in the development of
MASTERPLANS through photorealistic visualisation of stadiums and other
large areas, which aim at their most optimal and fast development.
Arzumanidis Constrution is subsidiary of Arzumanidis Investments, a
company that is involved in the study and construction of metal & massive
buildings since 2005. Our company's civil engineers design the metal carrier
with the use of the following software programmes: Instant CCS, EC4
Composite CCS structural design with Eurocode 4 composite building
structures, Fespa IV LH software, StruCad CCS metal design construction
software, Allplan 2008 design/architectural software, 3D Max.
The bioclimatic residences are designed using the bioclimatic architecture and
renewable energy principles. Furthermore, they are studied and constructed
according to the specifications of the owner, while the cost is not higher than
the cost of a common residence.
VIP residences are distinguished for the exceptionally low energy losses
(conservation of heating/cooling energy up to 70%) and the exploitation of
solar energy with the use of photovoltaic panels on the roof. Furthermore,
most significantly the VIP residences are constructed with ecological
materials, both human and environmentally friendly. As a result, these
residences, according to the classification of the new energy regulation
KENAK 2012, fall into the A+ category, thus offering multiple long term
benefits to the owner.
We use leading branded products and materials which offer a luxurious and
high quality residence. The delivery time for a finished 110 m2 residence
without basement is about 5 to 6 months from the start of the project. The
surrounding area is not included in this period of time.

be renewed for the period necessary for its completion. The contract will cover the
employer's civil liability for each case and up to the amount of 300,000 EUR per
accident and all risks insurance. The cost of the insurance contract is covered by
the employer.
2. EARTHWORKS - EXCAVATION
• Before commencing the general excavation, all existing flora will be
eradicated and the top soil will be stripped along with further loose
grounds. Excavation means the works on soil which aim at the creation of a
base for the foundations of the building.
• Mechanical means of excavation will be used.
3. FOUNDATION - CONCRETE The foundations of the building will be constructed using reinforced concrete,
category C20/2,5 and reinforced steel, category S500s, according to the antiseismic
regulation and the structural design as approved by the urban planning
department.
General base or strip footing will be used for the foundations, depending on the
requirements of the structural design. In the case of strip footing, the back filling
will be reinforced with ground slab.
Full checks are carried out on alignments and elevations (levels) before inserting
the casing, so that the dimensions are in accordance with the designs.
4. SUPPORTING STRUCTURE - SUPERSTRUCTURE The supporting structure (the frame of the ground floor and mezzanine
superstructure) is a composite construction made by merchant bars (Heavy duty
steel type H, HEA type columns, IPE type yokes, IPE purlins, HEA roof braces,
SHS vertical stiffness links) for columns and beams, and reinforced concrete for
slabs. For the construction of the steel frame we will use S275 (St 44) steel
according to EN10025, brand new, without damage or defects, guaranteed for its
chemical composition, treatability, sensitivity to brittle fracture, welding suitability,
which meets the requirements of EUROCODE 3 "Design of steel constructions".
C20/25 reinforced steel will be used for the slabs with dimensions based on the
approved structural design, the Greek Antiseismic Regulation and the Greek
Reinforced Concrete Regulation.
The slabs (slab on grade and floor slab) will be manufactured using C20/25
concrete and wire mesh of the appropriate T131 section.
The steel sheet of the composite slab is trapezoidal (type SymDeck73 or
equivalent), 73mm height (hp) and 0,75mm thickness, with end lengths and by
using all the necessary special items according to the design plans. The pre-
galvanised steel sheets are of S320GD Z275 quality, certified by an accredited
laboratory (EUROCODE 3 - Part 1.3 and EUROCODE 4).
Shear studs type Nelson 15-04-98 will be also used. The diameter of the shear
studs is d=19mm, d2=32mm and height 100mm or of equivalent type, ductile.
They meet the requirements according to EN13918. The welding of the studs is
specified by EN14555.
The elements of the supporting structure will be treated with paint as described in
the procedure below:
a. Degreasing according to SSPC-SPI
b. Sandblasting Sa2
c. Anti-rust protection with a layer of SHOP PRIMER
d. 150 microns thick painting using SIGMACOVER epoxy coating
Individual colourings are defined by the employer.
Frame elements are created by Fe430 steel standard commercial sections.
Cutting and welding will take place using modern machines and according to the
regulations and standards for the construction of steel structures. There has been
a study for the methodology of construction, equipment, the way of construction
and the placement of the metal frame aiming at the safe and immediate erection
and placement of all metal pieces.
APPLICABLE STANDARDS AND REGULATIONS
• Greek Regulation for Structural Works
(GG 325/Α/45 and GG 171/α/16-05-1946).
• Greek Antiseismic Regulation
• EC3 for steel structures.
For issues that are not covered by the above regulations the below is valid:
DIN 1055 construction calculations
The columns-beams are manufactured in the factory and transported to the site
appropriately formulated and painted. Their dimensions are in agreement with the
structural design, which has been drafted according to Greek regulations and
Eurocodes.
The metal poles attach to the foundation with the help of steel anchors type M20.
The anchors are linked together with plates in order to form one body and to be
placed and attached in the reinforcement of the foundations under the
responsibility of the contractor so that they will not be moved during concreting.
The contractor will draw the exact positions of the axes of the columns.
During concreting of the foundations, continuous inspections will make sure that
the flatness and alignment of the blades will be sustained.
On the trapezoidal sheet we will cast concrete type C20/25.
Emphasis will be given on its full vibration in order to eliminate any gaps in its
mass. The slab will be dampened on a regular basis until full strength is
developed according to the concrete maintenance specifications.
Following, the temporary shoring beams will be removed.
The stairs will be built using metal sheet 2mm thick in the form of steps.
Furthermore, the stairs will be supported by square sectioned beams sized
100*100*5 mm in its centre upwardly.
5. ROOF The roof is visible and manufactured by glue laminated fir timber from Finland.
The laminated timber beams are visible and placed at 70 cm apart with
galvanised screws and steel corners on the steel supporting structure of the
building. Their dimensions are 7.8 x 16.5 unless the structural design requires a
bigger section of 9 x 19. The panelling is made of large Swedish wood 14 x 1.6
cm thick. Also, we will use slats with dimensions 3 x 1.5, DIVOROL breathable
membrane with 15 cm overlapping, beams with dimensions 5 x 5 at 36 cm apart,
FIBRAN insulation 4 cm thick between the beams and second layer of insulation
(beams 5 x 5 - Fibran 4 cm). Finally the roof will be covered with GERARD
metallic tiles. Gerard tiles with natural stone chippings are manufactured using
steel covered with a blend of zinc and aluminium, which combines great strength
in all weather conditions with light weight (6 times lighter than common tiles).
Furthermore, the special design of the tiles and the horizontal placement ensure
high resistance in heavy snowfall, severe weather conditions and strong winds.
The tiles are placed with inclination from 15o to completely vertical. There is a
variety of colours to choose from. The advantages of these tiles are:
• Long working life
• Secure and resilient in severe weather conditions (snow, wind,
tornadoes, etc) because of the way they are placed
• Lightweight, 7 kg/m2. Gerard tiles are the most lightweight in the
market. Less weight on the roof means fewer loads on the supporting
structure. Furthermore, these tiles are easier to transport and place.
• Resistance to earthquakes
• They are accessible without sinking due to their ribs
• The sound of the rain is diffused and it is not annoying
• Resistance to temperatures from -45oC, as in areas like Siberia, to
+50 oC as in Saudi Arabia
• Wide range of colours

Installation of High Voltage The residence will be powered with three-phase power 230/400V from XT network of the power supply company. The meter will be installed on the fencing and will be connected to the main electrical panel of the residence with a subterranean wire, type J1VV-R, which will be placed in a PVC pipe. An independent panel will also be created which will be powered by the main electrical panel with J1VV wires. The superstructure electrical panels will be built in IP40 and made by self-extinguishing white plastic with transparent plastic door similar to Legrand Nedbox. The panels' departures will be protected by miniature circuits and the arrival by a fuse isolator. According to Regulations every panel must have leakage circuit breakers per departure team or in total. The panel equipment is made by ABB, Legrand or Schneider. The departure circuits of some panels will have A05VV wires or HOVV conductors inside plastic pipes, which will be built in the gaps of the plasterboard frame. In rare cases, they will be built in the masonry and coating. The wall materials for high and low voltage will be of the same series for the whole of the residence inside special areas (wet areas) and provided by Legrand Valena or Plexo. Each area will have the following: 1. An independent AOVV line, 5 x 2.5 with miniature circuit 16A and indicator lights for the stove 2. An independent ΑΟVV line, 3 x 0.5 with miniature circuit 16A and indicator lights for the washing machine 3. Any independent lines required for the solar thermal system
4.

Also, a waterproof earthed plug for each balcony. Installation of telephone station An accessible connection locker (distributor) will be created on the ground floor, which will contain the telephone line. This line will go to two telephone receptors in selected areas. UTP 4" category 6 wiring will be used for data transmission. Audio and Video door systems A central low voltage network will be created starting from the main entrance up to the ground floor hallway to serve for a closed communication circuit, audio and video. It is explicitly stated that the purchase of intercom devices is not in the agreement. Alarm system installation Piping and wirings will be positioned in suitable areas for the installation of alarm systems. The installation consists of a wire for magnetic contacts of all accessible exterior frames and the main entry. Furthermore, a wire will be provided for space radars on each floor according to specifications and a wire for the control panel and keyboard. Main TV antenna network A built-in network for terrestrial TV antenna with one socket per each main area, also piping and wirings will end on the roof in order to be linked to the IKUSI HD antenna. Furthermore, a SPAUN booster and SPAUN PV-SAT plugs are included. 19. COOLING - HEATING
For cooling - heating and hot water supply, a heat pump by Daikin will be installed. Daikin Altherma uses a natural source of energy. The outdoor unit extracts low temperature heat from the outside air and increases the temperature in order to provide the desired heating. Subsequently, the heat is transferred to the indoor unit through refrigerant piping. The indoor unit heats the water which circulates through fan coil units. Daikin Altherma system offers an equally effective solution for hot water. The hot water tank of the reservoir offers maximum energy performance. Initially, the water inside the tank is heated by the thermal energy of the air thanks to an exchanger which is linked to the heating pump. At the same time, an electric heater which is integrated on the top of the container heats up the extra hot water needed for the shower, bathtub or sink. Furthermore, an integrated function increases the water temperature to 70 degrees on fixed intervals, thus preventing the development of pathogenic organisms. This system consists of: a. Daikin Altherma monoblock heating pump One three phase 14 kW Daikin Altherma monoblock heating pump. The main heating pump feeder and the piping network with German multi-layered Uponor MLCP pipe and 9mm insulation. All other necessary components. In the Daikin Altherma Monobloc system, the hydrobox components are located in the outdoor unit. In this new system the water pipes, rather than the refrigerant lines, run indoors from the outdoor unit, making installation much quicker and easier. The reversible air/water heating pump contains a compressor which is controlled by an inverter. The inverter system constantly maintains the desired temperature. As a result, there is a reduction up to 30% on energy consumption comparing to the standard on/off system. b. Hot water system - Panels
Flat panel selective
Dual coil boiler 300 lt.
c. Daikin Floor FCU, series FWV The system consists of:
Six Daikin Floor FCU, series FWV, with controls on the FCU. Piping network with German multi-layered Uponor MLCP pipe and 9mm insulation. Regulatory synthetic Uponor collectors with balancing bolts for the FCU. All other necessary components, like sewage pipes. d. Main distribution network for Cooling - Heating pipes This network will be constructed using PRESS multi-layered pipes and components. Furthermore, it will be insulated completely with 9mm insulation. 21.
