Nice content sir.
I think the computation for mortar presented in the video is called the "Hundred Block Method" (HBM). For me, I still prefer the Area Method. Much easier for computation and we don,t need to worry about the annoying 100 value thing or 0.01 value (not 0.10).
I think there is a slight error in the computation. It's not the area of the wall that is substituted in the computation. It is the number of CHB.
So; (Class B Mortar)
For HBM Method
CEMENT = 573 pcs x 0.01 x 4.176 = 23.93 or 24 Bags.
SAND = 573 pcs x 0.01 x 0.348 = 1.99 or 2 cu.m
For Area Method
CEMENT = 45.84 Sq.m x 0.522 = 23.93 or 24 Bags.
SAND = 45.84 Sq.m x .0435 = 1.99 or 2 cu.m
Therefore, the computation shows similar results. The difference is the table factor they are using. There are other ways of computing the materials like the volume Method but requires patience to solve.
Furthermore, we will add the computation of plaster of the wall of two-sided surface, let say the thickness is 25mm or 1"
For Plaster for Class B Mixture in 25mm thickness
TOTAL SURFACE AREA = 45.84 Sq.m x 2 sided surface = 91.68 Sq.m
CEMENT = 91.68 x .300 = 27.50 or 28 Bags
SAND = 91.98 x .025 = 2.30 cu.m or 3 cu.m
Note: If you want a lesser thickness of the plaster of 16mm, the value for cement is 0.192, and 0.016 for sand in class B mixture
If we add the percentage wastage of each material on one side of the concrete wall, we will arrive at the overall quantity of that object. The wastage usually ranges from 5% to 10% depending on how your mason and labor work neatly and precisely. Let say 5% wastage
CHB = (573x5%) + 573 = 602 pcs
CEMENT = ((24+28)x5%) + (24+28) = 54.6 or 55 Bags
SAND = ((2+3)x5%) + ( 2+3) = 5.25 or 6 cu.m
The expected amount will be PHP 41,200 round-off of that material labor considering the 30% labor and 5% wastage. If we neglect the plaster in the computation, the expected amount must be PHP 27,500. We have noted also that on our sample computation, the contingency is momentarily neglected which I think when added to the estimate increases the amount.
Hope this help, thanks =)
Thanks for bringing this information sir. Have a great day po
Keep up your good work sir. More powers to come. =)
Hello and thank you to you both for a very informative and helpful post. I am wondering though why the plastering factor changes with thickness. Does this mean that the concrete mixture/ratio has to change too?
Engr. Romano thank you for your effort good job for sharing an informative ideas for those really need to understand how it will cost estimates do for preparation of budget & finance, much appreciated👍
Salamat po sa info at least alam Kuna ngaun Isang poste palang Pala naiipon ko
Very nice content
Have a great day and thanks for watching
Salamat po Sir Engr.Gabs sa mga video nyo..nakakatulong po siya sa learners na small time contractors....sana po gawa ka po ng video regarding concrete plastering po Sir Engr..
Sir bago lang ako sa channel mo,ang dami kung natutnan sa bawat video mo,my tanung lang ako sir my plano akung mag patayo ng bahay 5x12 meters isang palapag lang sir,ilang poste ba at kailangan ba na mag tie beam pa ako ba sir ,sana masagot mo amg tanung ko sir,thank stay safe and godblees sa family mo sir
Very informative po, sir. Salamat po. Instead of CHB, pano po pag buhos? katulad nung ginawa nung isang banyaga (CZcams - Texas Filipino). Kasi parang nakatipid siya dahil wala ng plastering.
Sir gab.isang mapagpalang araw poh.pwede poh b mag p estemate ng 4 by 7 ng 3storei
pwede po , need lang ng more time and plan. Thanks for watching
Paano po ang estimate ng labor para sa poste ?
Nice Kuya Gab.. My idol.. Thanks for sharing your knowledge
Thank you Lodi, hope to see u soon , keep safe
Maraming salamat po sa tapat na computation.. GOD BLESS YOU
Thanks for watching.
Sir pwede magrequest?Anu ba Ang tamang presyo Ng per sqr.mtr. tiles at plastering.
Depende po sa brand saka ung labor nababago din, gawa po aq video dyan soon. Thanks for watching
Good day engr..ano po ang break down ng 19 bags na cement?
mortar po para sa 4in chb class b
Ano po ba ang volume ng 1 bag of cement? salamat po
0.0277m3 = around 1cu.ft. sa ratio ng concrete proportion is in terms of cubic foot. 1:2:4 means 1cu.ft cement: 2cu.ft sand: 4cu.ft gravel. Thanks for watching
Pls explain saan galing ang values na 0.10 at 4.176 para sa cement,,
Also ang values na 0.10 at 0.348 para sa sand
Thank you...
nasa table po ng estimates ung values using 4in chb by volume method. thanks for watching
Kulang lng Ng plastering sir...di bale Sa magician Naman na🤣🤣😂 thanks much pa Rin..
will do it soon po. Thanks for watching
Sir di b malayo un vertcal bar n 1.2m ang spacing?30% lng po ang labor cost?
sa roughing in po 30% minimum, pwede po mag increase depende sa bawat situation. Thanks for watching
Pagawa nang bahay ko pag uwi ko
sure po, have a great day
Sir me Tanong lang po ako, pag Po ba bungalow type ang itatayo mo, kailangan po ba ang tie beam? Ty
Kahit di npo basta dipo masyadong mataas ang poste. Thanks for watching
Ty Po sa reply!sana in your future vlogs you will tackle also steel reinforcement details sa bungalow type house. God bless!
Sir gab pwede po ba yung permanent formwork ipalit ko sa chb with mortar 1:5:5 kasi 3corner kasi lot dikit lahat sa existing structure ng kapitbahay di ko mawaterproof at maplaster isang side eh . Ang tanong ko po yung mortar na 1:5:5 matibay po ba yun abot sa 4/f kasi po. Or may idea po kayo.kung chb gamitin ko maliban sa.flushing ano pa pwede nyo.recomend ano po.gawin ko para di pumasok tubig salamat po.
hello po di q po mavisualize gaano ung condition pero ang malinaw po eh kung pano pwedeng gawin sa pagitan ng wall nio para di pasukin ng tubig, kung may part na di pwede flashing gawin nio nalang po pulido ung pagsemente sa top ng wall para pwede pinturahan ng waterproofing.
@@GabsRomano salamat po sir gab
Boss paano ung mga pinto? Hindi pa naibawas ung CHB
same concept po sa estimating. Thanks for watching
Para saken kunin ang haba sukat pataas af haba sa ibaba
As you wish po
kulang po engr ng g.i.wire,,
Thanks for reminding po, +50 cents for the GI wire
Sir please correct the spelling of your hallow block!!! it must be hollow block!!!
Sure, Thanks for watching
Engr. Romano thank you for your effort good job for sharing an informative ideas for those really need to understand how it will cost estimates do for preparation of budget & finance, much appreciated👍
