Falsework - formwork. SITE ENGINEER needs to know when decking for next level slab.

In today's video I will show you decking for the next level slab and tell you all you need to know for these works. I will also show you the drawings from where we'll take the key information to get the job done right. This is the first video out of 4 covering the typical suspended slab in residential project.

Inform uk we’re our go too back in the day, we didn’t use titan formwork and they didn’t hire or sell it……black white n grey days lol

Thanks brother. We are doing decking at the moment.

El Fugitivo! Great news! you will do 100%

[@badveso]

I would mention only one thing about how high to keep the deck while decking. 5mm often is too much especially when the individuals who doing the deck keep it a few millimetres extra and you don't want to waste your time fixing it. As result you can lose the cover on the top which can cause more troubles. I recomend from my experience up to 250mm slabs no more than +3mm I don't know also and how many people know how this variations in the soffit level reflect the predicted concrete while cubing up and how important is the cubing the part load on the end.

[@SITENG]

Thanks for this. I add between 3 and 5 typically, but when doing that this level is to be kept, not any extra, as like you say this can cause other problems. 👍👍👍

[@Maksimov1337]

Those drawings are great! Whoever did those really knows what theyre doing! What viewer were you using where you could mark stuff up like that on?

@@SITENG Very cool I shall check it out! Can't believe you replied as well especially that quick. Thank you for that! Only discovered your channel today but as someone who's primarily done groundworks it's interesting to explore other parts of the trade too!

[@albertocarmonarosell3545]

Great video as usual Greg! What an absolute pain these slab steps are when they are everywhere…! I think it would be good to show how you set out the steps for putting up the decking from the floor below, set the laser level for the chippies and then marking the steps on top when the deck is released! Would be also great to see other types of formwork for vertical elements (single and double sided shuttering for liner walls, roof parapets, core walls, etc). There are a few things your friends have introduced on site that might be good to show here! Hope to see you soon man, keep it up!

[@SITENG]

Alberto, good to have you back here :) Many thanks!!! See you soon :) I will do now about marking decking and try to add more on the steps and marking below.

In recent years with the current race to the bottom with the standard of labour used, especially in large cities like London. It pays to assume every man is stupid and give them every bit of information possible, no matter how patronising it seems. When I started out 25 years ago the chippies would set out everything from the columns only the fixers would need setting out for the starter bars. These days most of the men are just labourers with hammers.

[@SITENG]

Yeah, that's right, it's definitely better to assume that everyone doesn't really know what they're doing😊 which unfortunately in many cases is the truth. When I started we had a surveyor coming to mark few gridlines and everything was measured off the gridlines by chippies. Here and now everything has to remarked and explained and still if you won't check it few time it might go wrong. That's how our job's looking right now, but it also gives opportunity for ppl to go for engineering if they have a common sense as setting out starts your career really 😁

[@unda25]

show how you calculate level of legs , or crodile , or what structure you do there , how you set you lase , and how you calculate , add notes in that yellow boook , i work with this sistem but for me is dificult to act like ingineer , always speak from the perspective of a shuttering carpenter

[@SITENG]

No probem, I will add this in next video, before jumping on top :)

[@ramk8436]

What is the career progression for Site engineers with Masters in Construction Project Management ? Will career be stagnant with just being a site engineer ?

[@SITENG]

Hi Ram! You can do whatever you like really, it's good to start as a site engineer, but if you want to go into project management you want to go to senior role and than to PM. You can always start as PM assistant, but I believe better PM is the one going through site engineering :)

[@lgurung736]

Thanks man i am also doing decking atm.. great help it would be

Glad I can help :)

Why 300 mm slab thickness provided us there this building use for heavy load storage. I know or here in india we maximum provided 150-175mm

[@SITENG]

The thickness looks crazy sometimes, on most residential you have 225 or 250 slabs which is a lot, some podium slabs are 400-500.

[@mahtab220]

@@SITENG okey, thats reason. Thank you

[@SITENG]

Someone told me it's for acoustic as well and remember this slabs are with no beams, but still could be thinner I know 😁

[@mahtab220]

@@SITENG if no beam where is slab support are given to column. Or there have hidden beam.

[@SITENG]

Slab sits on columns, punching shear steel is used around the columns, in some cases there is a need for column heads (in heavy loaded slabs)

[@InsideMyWall]

Do you maintain checklists for Inspection requests and get it approved by client before pour. If yes how do you do that and what are they?? The PERI drop head system is very interesting which release the shuttering materials. In general, after what period you remove the support system completely?

[@SITENG]

Yes I do. We are using Fieldview software, so everything has to be done 'as we go'. Removing all support depends on concrete strength results and backpropping needed for higher slabs. Drop head system is really great :)

[@InsideMyWall]

@@SITENG So you maintain all Inspection requests and RFI on Fieldview. It is a very good software where all the project details can be monitored. Will love to see a video doing exactly that "On the Go". Will like to see how the total process shapes up before a pour.

[@InsideMyWall]

@@SITENG Will like to hear your views on the formwork stripping. Does your code has any provisions to estimate the strength of the concrete after say 10 days of pouring. Our code has mentioned a general table mentioning Number of days (related to structure and span condition) after which the formwork can be safely removed. It is more on the conservative side.

[@SITENG]

I'll try show it too, but I am on different job now and we're not using it here.

[@SITENG]

This depends on the cube strength result. Sometimes we're crushing cubes next day on site to check if we're achiving 21.6 N/mm for early strike. Sometimes we are using concrete sensors (installed in the concrete while pouring which base on T gives you concrete strength) and sometimes also just waiting for laboratory cube result. From Peri ''m. Depending on the slab thickness and concrete strength, the SKYDECK Drophead allows striking to take place after only 1 day: see table containing minimum concrete strength and striking guide values''.

[@ColexPreston]

Great video, I've levelled a few decks in my time and it's a nightmare if they are too low then fixers jump on top and your trying to hammer the legs up 😁

[@SITENG]

Thanks Jamie! Yeah, that's a nightmare really :)
