Simple procedure follow in the installation of the fascia.

1. The head beam is boarded only at the inner part and the outer part is left open.

2. A gap from the top of the head beam wood equal to the fascia height is then allowed (450mm or 300mm)
A 2 x 4 is nail in the outer part of the house to receive the polystyrene fascja

3. The head beam reinforcement is placed into the the former to serve as the top reinforcement.

4 the polystyrene is placed using binding wire and attached to the head beam through the use of binding wire and a short 12mm bar.

5.The head beam and polystyrene is then cast together to form a solid concrete.

6.thw Formwork is the removed and the joint of the fascia is then dressed with the polystyrene cement

I am still on the polystyrene fascia
I will be highlighting all the important things or activity to carried out for those that will like to use this method for their future work.

Polystyrene comes in three meters each apart from the ridge or Valley. All other part comes in three meters.

Polystyrene is measured in linear meters and not per meter square.

Polystyrene can be bought in standard size of 450mm x 450mm or 300mm x 300mm. It can also be made on special order.

The 450mm x 450mm goes for around N4,500
While 300mm x 300mm is sold for N2600

The polystyrene also comes with a special cement used to join the point of contact between polystyrene.

I am back with more updates after today's work.

@Bolded...Is this a good thing or a bad thing? What is the implication?

Always better to run your head beam together.

i grew up in a flat with the bathroom tiled up only from under the window downward (5 feet) and it doesn't look dirty and my current bathroom doesn't even have a single tile and doesn't look dirty either. it's just a matter of choice and pocket size. what i would never have in my house is tiles on the bathroom floor.

Without a single tile' that don't sound good. Your wall will end up soaked up and weakened by action of water and detergent, it may also messed up other side of wall paint

this is nice.
are the valleys and ridges also included in the fascia or roof?

They are included in the fascia

The composition of the fascia includes
The head beam and the polystyrene fascia.

The head beam is 15mm x 225mm
Thhe polystyrene fascia is 450mm x 450mm

Steps follow to calculate the quantity of polystyrene needed
The roof perimeter was estimated to be 110 m
The number of Valley and ridges were noted to be 7 and 10 respectively,
Each of the ridge is 1.2m while the valley is 0.6m
The ridge is added to the actual perimeter while the the valley is subtracted from the actual perimeter

Q = P +(n x R) - (n' x V)
Q = quantity of polystyrene needed
P = building perimeter
n =number of ridges
n' = number of Valley
V = Valley
R= ridges

The choice of fascia was purely down to those aforementioned reasoned. At the end we were in a dilemma of either using precast fascia or polystyrene fascia.

The client wasn't really conversant with the polystyrene fascia and we need a lot of discussion and persuasion to make him get comfortable with the polystyrene fascia.

The choice of polystyrene over precast fascia were due to very light weight, speed and flexibility.
The major problem with precast is it is not that flexible because of the weight and such make lifting very difficult. Precast can also be time consuming

After all these masonry work, we then proceed to the construction of the concrete fascia at these points we stumble on a very vital information about the structural configuration of existing building.

The existing building was about 25years old built entirety with non hollow sancrete block, with only column on the ground floor.

The slab act with the column like a flat slab and also act directly on the partition walls, making the wall to be non load bearer.

Due to the above structural issues with the building, the fascia of 450mm - 600mm need to be very light so that the torsional moment on the upper walls will be minimal.

At these point we have three options of concrete fascia
The options are as follows
1. Reinforced concrete fascia
2. precast concrete fascia
3. Polystyrene concrete fascia

We have some set of constraints while considering these options, our constrain are as follows
1. Speed of job because we need to roof the building as soon as possible due to excessive rain on the building
2. Cost of the fascia because we need a relatively cheap/affordable fascia
3.durability because we need fascia that will stand the test of time
4. Finally, beauty aesthetics because we need a facial that will come out beautiful.

Window modification, construction of new stair, partition removal and addition of partitions were all grouped under 'All masonry work before concrete fascia /roof.

A lot of attention and care was put into all these work to make sure that the building is safe atructurally from any modifications.

The Harney team were always on site to guild the technical and artisans alike to achieve a beautiful structure/building that the client will like and that can fetched us more job in future.

At Harney project, our policy is a handsone project to always be on site at any time, we are young and eager to established ourself.

PeoplesArmy:
This is the Harney Projects Team? Hmmm....Young guys. Who is Abdulwastecx and who is Podosci?

The short guy is abdulwastecx
The taller guy is podosci

greenermodels:
chairman, how's work? please advice me on a good structural software for reinforced concrete design that will have tutorials easily available.

Try Orion

johnson232:
nice work my engr. pls i really do need detailed info abt the polystyrene fascia.

I will give you that sir

Onuokwu:
Does it mean with this you don't need to do screeding? Will it accept acrylic emulsion paint without screeding?

Screeding is optional as stated earlier

johnson232:
pls am abt doing renovation, i want to convert an existing building to guest house.
am considering using polystyrene for the parapet work, as i wont be able to break down the walls for the pillars.
my questions;

the polystyrene are made of which materials?
how durable are they?
hw can i get them?
are u on whatssapp or bbm?
thanks. cc:mufutau55

I have a dedicated thread for a massive renovation work I am currently working on, you will get all the information there sir

Polystyrene are made from petrochemical raw materials, similar to those whitish stuff used to package electronics

It's very durable.

I procure the one I use for the project from Abuja

Yes I am on whatsapp and on bbm

mufutau55:
This is a heavy duty renovations o. Keep up the good work.

Hajji M.

Thanks sir

the new stair have the following information
1. width of stair = 900mm (4ft)
2.riser heigh = 150mm
3. thread = 300mm
4. waist of the riser = 175mm for the first flight and 200mm for the second flight
land = 2000mm x 900mm and with depth of 175mm

Removal and construction of new stair

the stair at the front prior to removal.
type of stair: dog leg stair case
reason for removals includes:
1. uneven riser
2. waist too thin ( waist shouldn't be less than 150mm)
3.uneven thread
4. Half of the stair is a ramp and make movement impossible

My rules are simple.
to have a good a very good finished wall you need to have a good stable wall that moisture will not rise through, will not crack due to settlement or over loading. You need to have a very good plaster sand, very good mix (preferably 1:1:4) and then all other things follows.


Those are the pictures from my ongoing work
