1 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails BRIEF INTRODUCTION OF 3D CONSTRUCTION SYSTEM

2 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails INTRODUCTION The 3D Construction System is a cost-efficient construction system based on industrially prefabricated 3D panels. The 3D panels consist of an EPS core with a thickness ranging from 40 to 150 mm sandwiched between two plane-parallel welded wire mesh sheets (cover meshes) and inclined diagonal wires in between that go through the EPS core and that are welded to the cover mesh’s line wires. This results in a light-weight, three-dimensional truss system with a high inherent stiffness.

3 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails 3D-ELEMENTS Conventional Materials  Concrete  Reinforcement  Steel Diagonals  Polystyrene

4 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails PANELS AND SHOTCRETE  2 Materials for the entire building

5 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails BOX-LIKE STRUCTURES  The box-like structure guarantees maximum resistance against earthquake forces.

6 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails SAFE CONNECTIONS OF NON-STRUCTURAL ELEMENTS No danger due to non-structural elements (e.g. collapsing brick walls) continuous mesh reinforcement no connection brick-column or beam

7 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails HEAT AND SOUND INSULATION  Heat insulation depends on thickness of EPS and number of diagonals - adjustable for different climates U-value can go up to 0.24 W/m²K  Sound insulation depends on weight of wall average sound reduction:R = dB combined with dry walls:R = dB

8 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails LIMITS OF 3D STRUCTURES  4 to 7 stories additional columns in critical areas can increase the number of stories  length of slabs up to 6m small beams between panels can increase the max. length of span  height of walls up to 6m

9 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails HOW TO BUILD WITH EVG 3D CONSTRUCTION SYSTEM Construction work with 3D Construction System is a simple step- by-step procedure. A few skilled workers (masons and carpenters) are required only. Most of the workers can be unskilled.

10 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails ERECTION OF WALL PANELS Step 1 of 8:  Start erection in corners  Connection to starter bars

11 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails CONNECTING WALL PANELS Step 2 of 8:  Fixing splice mesh – Pneumatic tools (hog ring guns) – Conventional pliers

12 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails SHORING Step 3 of 8:  Adjustable props with tripods  Beams to support panels

13 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails PREPARATION OF SLAB PANELS Step 4 of 8 Additional reinforcements  Straight Rebars (flexural reinforcement)  Stirrups (support)

14 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails PLACING SLAB PANELS Step 5 of 8  Space between beams max. 1.5m 1.50m

15 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails TOP CONCRETE ON 3D SLABS Step 6 of 8  6cm concrete on top of slabs

16 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails SHOTCRETE ON 3D WALLS Step 7a of 8  40 to 50mm Shotcrete  1 or 2 Layers

17 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails MANUAL PLASTERING Step 7b of 8  40 to 50mm Plaster  3 Layers

18 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails WALL FINISHING Step 8 of 8 1st layer of  Shotcrete  finishing layer (smooth surface)

19 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails CHARACTERISTICS OF EVG 3D CONSTRUCTION SYSTEM The 3D Construction System meets all structural and physical requirements relating to building physics. Especially, when it comes to structural strength 3D offers some unique opportunities. Not only tests but real life experience with earthquakes and hurricanes, as well show the remarkable strength of 3D Construction System.

20 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails SIMPLE INSTALLATION PROCESS  No special tools required  Simple step-by-step procedure WALL PANELS PANEL CONNECTION SLAB PANELS SHOTCRETESHOTCRETE CONCRETECONCRETE

21 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails HEAT INSULATION 3D (20cm)  Reduced costs for A/C systems or heating systems and reduced operating costs Bricks (60cm) Concrete (100cm)

22 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails LIGHTWEIGHT Compared to concrete 3D provides for:  90 % rigidity  50 % weight  reduced costs for foundation

23 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails DURABILITY  3D structures in coastal areas  Excellent protection due to tense shotcrete cover  Long life time of 3D structures Jolly Harbour, Antigua

24 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails Cantilever Wall UNIQUE DESIGN OPPORTUNITIES  Domes and roofs without internal support  Walls acting as deep beams

25 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails EARTHQUAKE RESISTANCE  6.5 and 6.9 on Richter Scale  No damage

26 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails HURRICANE RESISTANCE  Habitat for Humanity, Florida  Hurricane Andrew (September 1992)

27 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails MONOLITHIC STRUCTURES  Foundation washed out after a dam break  Secure structures under every soil condition

28 Peh/ IntroductionHow to buildCharacteristicsProjectsMaterialsDetails ADVANTAGES  Fast and easy erection with unskilled labour  Economical use of local materials  Structurally stable construction  Good thermal insulation  Use of prefabricated elements produced on an industrial scale (thus, low cost)  Great variety of design features  Minimum installation work on site (no cranes)
