Introduction<br />
The Flexus Modular Flooring system are prefabricated<br />
modules comprising of a 30mm thick Flexus ECC<br />
(Engineered Cementitious Composite layer supported on a<br />
Pryda Truss (either PrydaSpan or Longreach Truss system)<br />
or LVL Joist system.<br />
The patented system forms a sub or mid-floor for typical<br />
structures such as timber, steel, concrete, masonry or brick<br />
and is suitable for use in:<br />
• Light Commercial Buildings<br />
• Low-rise <strong>Construction</strong><br />
• Apartments<br />
• Residential Housing<br />
• Pre-fabricated Buildings<br />
The Flexus Modular Flooring system can be used<br />
on either new buildings or retrofit interior and exterior<br />
situations.<br />
Flexus Modular Floors are manufactured under strict<br />
quality control standards by approved fabrica<strong>to</strong>rs.<br />
ECC<br />
Flexus is an engineered cementatious composite<br />
(ECC) material that has unique properties unlike other<br />
cement / sand products.<br />
It has a high compressive strength (like concrete) and<br />
features a tensile strength much higher that concrete.<br />
When the nominal tensile strength of Flexus ECC<br />
material is exceeded, it micro-cracks and gains<br />
in strength as more load is applied. Unreinforced<br />
concrete and timber, in comparison, cracks and gives<br />
way suddenly. ECC exhibits ductility more like steel;<br />
providing a safer more appropriate structural material<br />
that is ideal for the Flexus Modular Floor.<br />
The fine materials allow an F5 smooth finish <strong>to</strong> be<br />
formed from a steel casting bed on the <strong>to</strong>p surface.<br />
The 30mm thick ECC <strong>to</strong>pping is attached <strong>to</strong> the<br />
supporting floor trusses or joists through regularly<br />
spaced Pryda connec<strong>to</strong>rs.<br />

Pryda Truss <strong>Systems</strong><br />
Pryda Floor Truss <strong>Systems</strong> are a complete structural<br />
system for timber floors made up of flooring material,<br />
floor trusses, strong-backs, connections and bracing.<br />
They have been proven for many years and provide<br />
occupiers with floors that have an excellent and<br />
predictably reliable performance.<br />
All trusses use commonly available timber and most<br />
floor trusses in New Zealand are made from 90mm<br />
Kiln Dry timber.<br />
There are two types of web systems for these trusses<br />
using timber chords. Pryda Longreach uses all timber<br />
webs, while Pryda Span uses metals webs for the<br />
diagonals and timber webs for the verticals.<br />
Both systems of Pryda Floor Trusses are generally<br />
made <strong>to</strong> order by licenced fabrica<strong>to</strong>rs. While there are<br />
standard end details that allow trusses <strong>to</strong> be trimmed<br />
on-site, this practice is not common. This is not only<br />
because all trusses are designed for an exact span<br />
for economic reasons, but the interaction between<br />
the true span of the trusses and the flooring should<br />
be considered for proper dynamic performance<br />
assessment.<br />
Pryda Span Trusses<br />
Flexus Modular Floor<br />
Pryda Span trusses have metal diagonal webs for<br />
lighter weight and cost-effectiveness. They are ideal<br />
for shallower trusses where there is a need for more<br />
clearance room <strong>to</strong> accommodate services and for<br />
trusses where the chord design has some reserve<br />
capacity. In some instances, some diagonal metal<br />
webs may have <strong>to</strong> be replaced by timber webs as load<br />
or geometry considerations dictate.<br />
Webs may be on both sides of the truss, or just on<br />
alternate sides. In the latter case, this allows for the<br />
webs <strong>to</strong> overlap.<br />
Pryda Span trusses are referenced as PS25, PS30<br />
or PS40, where “PS” means Pryda Span, and “30”<br />
is the nominal overall depth (cm). The overall depths<br />
are in specific steps, but are actually 260mm, 310mm<br />
and 420mm (note - the 30mm ECC <strong>to</strong>pping must be<br />
added <strong>to</strong> give overall floor module depth).
Pryda Longreach<br />
As the name suggests Pryda Longreach trusses are<br />
suitable for longer spans. Overall truss depth may<br />
increase depending on the span and performance<br />
required. Longreach trusses also have open webs<br />
allowing easy installation of services.<br />
Flexus Modular Floor manufactured with LVL for a sub floor.<br />
Other Timber Joist <strong>Systems</strong><br />
LVL Joists<br />
Flexus is suitable for use with a LVL joist system. New<br />
Zealand’s major LVL suppliers provide joist design<br />
software suitable for residential situations and a design<br />
service for specific design.<br />
Solid Timber Joists<br />
If preferred, Flexus Floor Modules can be designed <strong>to</strong><br />
use solid timber joists. For design information contact<br />

S1: Compliance with the New Zealand Building Code (NZBC)<br />
If designed, used, installed and maintained in accordance with statements and conditions contained in this<br />
document, the Flexus Modular Flooring System will meet the following provisions of the New Zealand Building<br />
Code.<br />
Clause B1 – Structure : Performance B1.3.1, and B1.3.2. The Flexus Modular Flooring System meets<br />
requirements for loads arising from self-weight and impact (i.e. B1.3.3 (a), (b) and (j).<br />
Clause B2 Durability : Performance B2.3.1 (a) not less than 50 years.<br />
Clause C3 Spread of Fire: Performance C3.3.1.<br />
Clause F2 Hazardous Building Materials: Performance F2.3.1.<br />
Clause G6 Airbourne and Impact Sound : Performance G6.3.1 and G6.3.2.<br />
S2: Acoustics<br />
For inter-tenancy applications the Flexus Modular Flooring System achieves an STC of 57 and IIC of 81. A full<br />
acoustic report compiled by an independent acoustic consultant is available at www.flexus.co.nz.<br />
In summary, performance requirements of the NZ Building Code are:<br />
Clause G6 Airbourne and Impact Sound :<br />
Performance<br />
G6.3.1 The Sound Transmission Class of walls, floors and ceilings, shall be no less than 55. (STC 55)<br />

S3: Fire Rating<br />
The Flexus Modular Flooring System comprises of two<br />
main elements, a support structure and a floor <strong>to</strong>pping.<br />
The support structure is either a timber or steel joist or<br />
timber truss layout as per a normal built up floor.<br />
The plywood or particle board sheet flooring of a built<br />
up floor is replaced by a monolithic cementatious floor<br />
sheet (Flexus material) that spans the length of the<br />
joists and up <strong>to</strong> 2400mm in width.<br />
The whole of the Flexus floor sheet (span x width) is<br />
made as a module complete with the supporting truss<br />
or joist system in a fac<strong>to</strong>ry environment and delivered <strong>to</strong><br />
site ready for installation.<br />
Once the Flexus flooring modules are in place and<br />
secured, services can be run through the floor space<br />
and a ceiling installed <strong>to</strong> the underside of the modules.<br />
For fire rating we follow the recommendations of the<br />
Wins<strong>to</strong>ne Wallboards Ltd publication Gib® Fire Rated<br />
<strong>Systems</strong> for fire rated floor/ceiling systems and any<br />
specific recommendations from the joist/truss supplier/<br />
manufacturer.<br />
Gib® fire rated systems use a 20mm particle board<br />
floor or a 17mm plywood floor as a minimum.<br />
The Flexus floor sheet is a non combustible<br />
cementitious material 30mm thick. By common<br />
engineering knowledge of materials, Flexus has a<br />
superior fire resistance than the wood based thinner<br />
materials used for the Gib® fire rating. Therefore, <strong>Reid</strong><br />
are comfortable using in accordance for the situation,<br />
the fire ratings for Gib® board ceilings as per the Gib®<br />
Fire Rated <strong>Systems</strong> publication for Flexus flooring<br />
modules until specific fire tests are completed.<br />
Flexus Modular Flooring System can be used <strong>to</strong><br />
provide passive fire protection in accordance with the<br />
requirements of NZBC Clause C3 – Spread of Fire.<br />
In order <strong>to</strong> satisfy the requirements of NZBC Clause C4<br />
– Structural Stability during Fire, designers must ensure<br />
that fire rated elements are supported by elements<br />
having at least the same Fire Resistance Rating (FRR).<br />
Collapse of elements having a lesser FRR shall not<br />
cause the consequential collapse of elements required<br />
<strong>to</strong> have a higher FRR.<br />

4.1.1 Fac<strong>to</strong>rs Affecting Floor Performance<br />
Floor liveliness, or bounce, has been an intermittent issue over the years with lightweight residential floors – for all<br />
forms of timber and steel construction. To eliminate these problems, Pryda Floor <strong>Systems</strong> are designed <strong>to</strong> stringent<br />
dynamic performance criteria.<br />
Pryda Floor <strong>Systems</strong> have three options for floor performance that can be selected by the designer;<br />
• AS/NZS 1170: 2002 as the minimum criteria.<br />
• “Pryda Build” truss design software design option of “normal” is more stringent<br />
• “Pryda Build” truss design software design option of “Enhanced” is used for those who want a superior performance<br />
overall.<br />
The floor truss is only one component that can affect the floor performance. The engineer should also consider the<br />
vibration performance of the supporting structure. On-site conditions are always important and proper attention <strong>to</strong><br />
detail must be taken at the time of installation.<br />
Flooring Material<br />
The flooring material has a significant effect on the perceived bounce of a floor. It has the ability <strong>to</strong> spread human<br />
impact loads depending on the material and the thickness. Plywood acts differently <strong>to</strong> particle board, and T&G acts<br />
differently <strong>to</strong> both. A simple way <strong>to</strong> improve floor performance is <strong>to</strong> select flooring that is stiffer (e.g. thicker) than the<br />
minimum for your chosen application.

S4.3 Floor Diaphragm Action<br />
Flexus Floor Modules can be used for diaphragm action <strong>to</strong> transfer loads <strong>to</strong> boundary shear walls. Specific<br />
information is required for detailing module connections <strong>to</strong> suit the application.<br />
This information from the engineer must include location of shear walls in relation <strong>to</strong> floor diaphragm support<br />
structure and predicted shear flows in kN/m.<br />
S4.3.1 Information required by fabrica<strong>to</strong>r for Flexus Floor design<br />
• Detailed plans with dimensions of Flexus Floor location.<br />
• Sections through support locations<br />
• Ceiling construction<br />
• Any super dead loads/live load<br />
• Any braced walls and concentrated loads <strong>to</strong> be carried by floor modules<br />
• Design shear flow in kN/m.<br />

S4.6 Accessories - Installation<br />
4.6.1 75mm and 90mm Timber Nails<br />
A number of 75mm and 90mm timber nails are<br />
required <strong>to</strong> provide adequate fixing between the timber<br />
floor trusses where the modules meet. These nails are<br />
required through the bot<strong>to</strong>m chords.<br />
4.6.2 Metal tek Screws<br />
Metal Tek Screws are required if specified in any fixing<br />
details.<br />
4.6.3 Coach Bolts and Screws<br />
For applications where the Flexus Floor is required<br />
<strong>to</strong> be fixed <strong>to</strong> an I-Beam, timber packers are required<br />
within the I-Beam flanges. Coach Screws and Bolts<br />
can be specified as the fixing method for the stringer<br />
on the module in<strong>to</strong> the timber packers.<br />
4.6.4 Metal Timber Connec<strong>to</strong>rs<br />

S4.7 Conditions<br />
4.7.1 Moisture Content<br />
Maximum moisture content of timber framing <strong>to</strong><br />
NZS 3602.<br />
4.7.2 Building<br />
Ensure foundations or wall frames are constructed in<br />
accordance with NZS3604.<br />
4.7.3 S<strong>to</strong>rage<br />
Timber expands in thickness and depth when allowed<br />
<strong>to</strong> get wet.<br />
To ensure the Flexus Floor Modules stay dry, straight<br />
and true at the time of installation, the following<br />
recommendations regarding s<strong>to</strong>rage are made :<br />
• Stack on evenly spaced level bearers <strong>to</strong> keep flat<br />
and straight.<br />
• Provide a surface for the materials <strong>to</strong> be placed on<br />
that is in plane.<br />
• Stack well clear of the ground for good ventilation.<br />
• S<strong>to</strong>re under cover <strong>to</strong> keep dry prior <strong>to</strong> installation.<br />
4.7.4 Handling<br />
• Handle with extreme care. Protect edges,<br />
corners, truss and surface finish from damage.<br />
• A crane or Hiab is required for the placement<br />
of modules – for example a 6mx2.4m Module<br />
weighs approx. 1.1 <strong>to</strong>nne.<br />
• Module weight = approx 82kg/m2 (based on<br />
module with overall depth of 450mm)<br />
• Specially Modified <strong>Reid</strong> Swiftlift Face Lifting<br />
anchors (installed in<strong>to</strong> 30mm ECC <strong>to</strong>pping) are<br />
used with a <strong>Reid</strong> Swiftlift Lifting Clutch <strong>to</strong> safely lift<br />
the Modules.<br />
• Standard Personal Safety Equipment applicable<br />
<strong>to</strong> the activity must be worn when handling<br />
Flexus Floor modules. Refer Department<br />
of Labour Health and Safety in Employment<br />
regulations and information.<br />
4.7.5 Substrate<br />
Do not commence work until the substrate is of the<br />
standard required by the relevant manufacturer’s<br />
technical literature for the specified finish; plumb, level<br />
and in true alignment. Maximum moisture content of<br />
timber framing <strong>to</strong> NZS 3602.<br />
Fastening the modules <strong>to</strong> the framing.<br />

S5: Internal Walls<br />
Internal Non-loadbearing Walls.<br />
The Flexus Modular Floor system requires no additional<br />
stiffening when supporting non-loadbearing walls.<br />
For situations where these walls act as wind bracing walls<br />
then consult the <strong>Reid</strong> Engineering Design office.<br />
Internal Loadbearing walls.<br />
If the Flexus Modular Flooring modules are going <strong>to</strong> be<br />
supporting Internal Loadbearing walls then consult the <strong>Reid</strong><br />
Engineering Design office. Information on vertical and shear<br />
loads from these walls will be required.<br />
Non-Loadbearing Walls under.<br />
Floor trusses must be adequately supported on the<br />
loadbearing supports nominated in the design. There may<br />
be a detrimental effect on the walls and the flooring system<br />
if the trusses bear on a non-loadbearing wall. The <strong>to</strong>ps of<br />
internal non-loadbearing walls need lateral stabilising by<br />
fixing <strong>to</strong> the truss bot<strong>to</strong>m chords. The trusses must be<br />
allowed <strong>to</strong> deflect downwards.<br />
Loadbearing Walls under<br />
Should an internal wall be required <strong>to</strong> support floor trusses<br />
and/or behave as a shear wall <strong>to</strong> transfer diaphragm loads,<br />
this intention should be made abundantly clear on both the<br />
trusses and the truss layout.<br />
When the floor modules are designed, any internal<br />
loadbearing wall under has <strong>to</strong> be fac<strong>to</strong>red in<strong>to</strong> the truss<br />
design.<br />
S6: External Walls<br />
External Loadbearing Walls.<br />
Where external loadbearing walls are being supported by<br />
the floor modules the floor detailer needs <strong>to</strong> be made aware<br />
of this so that additional roof and wind load can be fac<strong>to</strong>red<br />
in<strong>to</strong> the floor truss design.<br />
