Construction Cost - your basic guide to estimating

[tholits1224]

[tholits1224]

This is based on a formula which is accepted by Architects and Builders here in the Phils. The formula put simply, is this:

To estimate the minimum of a house, multiply the floor area by P12,000.00 to P16,000.00 to P20,000.00 to P32,000.00

For example:

50sq.m x P12,000.00/sq.m = P600,000.00
50sq.m x P16,000.00/sq.m = P800,000.00
50sq.m x P20,000.00/sq.m = P1,000,000.00

Hence, the minimum cost of the house will be P12,000.00 this includes the cost of labor and materials. For a house constructed as a liveable shall be the cost maybe estimate at P12,000.00 per sq.m in this case a 50sq.m house at P12,000.00 per sq.m would be P600,000.00 to build

What type of a house would you get if you followed the minimum cost forumula?

First, we assume the existence of electricity and water in the area or subdivision where you are putting up your house. If you have to provide your own water supply, you will have to shoulder additional expenses. If there is no electricity, you should start looking around for another lot or apply for electric line.

Second, the materials/finishes will only include the following: reinforced concrete footing, columns and beams, 6" concrete hollow blocks for exterior wall plus vinyl tiles for flooring;

For two storey houses, the flooring and roof framing system will be of wood, roofing will be G.I sheets and ceiling will be plywood. Toilet and baths will have complete fixtures in vitrified glazed and unglazed tiles.

[tholits1224]

Yes, you can build a house for much less than is liveable. Impossible? definitely not!

When we say liveable, we mean a house that includes the basic necessities such as toilet and bath, kitchen sink and counter, plumbing, electricity, together with living and sleeping area, and is ready for occupancy. Liveable spells functional. This type of house grows with your budget. The finished can come late.

[tholits1224]

If your budget allows you to spend more on your house, you will be able to spend more on finishes. When we talk about finished, we refer to additional decorative items such as Narra for doors, wrought iron grills for the windows, marble for the floors, Spanish clay tiles for the roof and so forth, that will serve to enhance the beauty and value of your home.


Maximum Cost.

The house picture above that use luxurious finished and fixturs, reflect these additional expenses in the cost estimates and are classified as Maximum Cost.

Our formula for Maximum Cost is:

Floor Area x P20,000.00+ (depending on the extent of additional items)

Tomorrow I will post about the cost of Basic Construction / Finishing Materials.

tholits ano name ng construction company nyo?

thats a good guide..

thats a good guide..

Agree.But it has to be emphasized that it shall be treated as a guide and not a total reference because not all people here in this thread are knowledgeable with construction cost and quantity estimate to be able to completely discern if such a price range would be applicable to the project that they[the project owners] intend to build. This may somewhat be treated like an 'SRP'...gaya sa softdrinks, Php 6.00 SRP pero you can buy the same volume and brand for only P4.00 direct from dealers, P7.00 in most sarisari stores, P8.00 pesos in canteens and P10.00 in fast food restaurants or even P15.00 in some fancy restaurants.

siguro naman maiintindihan ng sinuman makakabasa na ang title ng thread ay - your basic guide to estimating...

tulad na nga ng nasabi ko sa ibang mga threads dito sa PeX, I'm an event organizer and we have upcoming event - The Manilacon 2010 in cooperation with Green Architecture Advocacy Philippines.

gusto ko lang mag share ng konti sa ating mga kaibigan dito sa forum.

tholits ano name ng construction company nyo?

hindi po kami contruction company, pero madami ako kaibigan na mga contractor at architects na kilalang namin na tapat at maayos kausap.

example ng pagiging tapat na architect hindi tumatanggap ng komisyon o percentage na inaalok ng sales representative ng isang company kahit nabenta yun materials sa client ni architect.

meron ba nun? liar o clueless?

maaaring hindi na-hit ang threshold level...
ako siguro, magsisimulang mag-isip kung current net pay per year x 10 ahahahaha...


but what tholits1224 is sharing is excellent stuff, although the 20k/sqm for the high end may still be a bit low.... please keep it coming

20K/sqm yan yun quotation sa isang eco house project ni Archt. James Jao... pero nagkaroon pa rin ng konting adjustment dahil sa ginamit na solar panels at nag decide yun owner na Megaman ang lightings...

this coming Sept. 2 to 5 may showcase ulit kami ng Eco House highlight ito ng Manilacon 2010... 8 working days matatapos namin yun bahay actual ito, pati yun materials kung ano ang naka specify sa plano yun ang ilalagay..

gusto nyo makita please check the site on Aug 22, SMX parking area doon sa harap malapit sa MOA Department Store... Aug 23 itatayo namin yun mga walls then sunod-sunod na...
Sept. 2 kailangan ready for viewing na itong Eco house na sinasabi ko or elase masasayang lang pagod namin at renta sa area.

meron ba nun? liar o clueless?

Both.Merong liar, merong clueless.Hindi naman masama ang commission...besides, hindi naman sa lahat ng project nangongomission ang mga architect/designers and most of the time, hindi naman talaga ito commission per se...kase hindi naman talaga nagmamatch sa standard "commission" rate.Sense of gratitude na lang iyan ng supplier/dealer/contractor sa deisgner/architect.And while others do not directly accept the so-called "commission", what they do instead is ask for favors from the contractors/supliers/dealers like: "Oh, may sira ang bubong ko,baka pwedeng pakitingnan mo naman?" Understood na iyon that you have to repair it at no cost or kung talagang maginsist naman si architect/designer na magbayad pa rin, at a minimal cost.
Saka nobody would dare recommend a dubious material/contractor naman kahit may commission pa eh.Designers/Professionals also have their names to protect.

Kailangan lang i-emphasize.Not everyone who understands it wants to accept it.

Well, for me, I guess the things that we share to other people(especially online,where we can have a million viewers) has to be filtered in some way and has to be a limit. For instance, would you and could you give us the nitty-gritty of holding up an event including your sources for location, services,etc.? If so, please share it with us so that we can also hold events as such kahit maliliit lang.

A little of anything can be dangerous.

although the 20k/sqm for the high end may still be a bit low.... please keep it coming

Agree.This price for a high-end home was the price 8-10years ago.Very far from the price of construction materials.A kilo of Grade 60 steel is not the same as it was 10 years ago...same it is with cement.Quality does not really need to be expensive but it does demand premium cost.Materials may be good, but check the workmanship first and vice-vers...

Peace.

yeah, entry level to the big leagues would start at 35k/sqm, according to my friend who does this for a living... but then again, it can also be a matter of sourcing.

My actual experience is that the kitchen and the bathrooms can really drive the unit cost way up. Plus if you're a fan of cathedral ceilings...

Yeah, exactly. Indeed it can also be a matter of sourcing and who sources out.As an example, my previous employer can get as much as 40% off from a roofing supplier/contractor on materials cost...but this is because we had a big volume.It is just the same for contactors who'd say that "they can build if for less" but this is because they buy their materials in bulk(most of the time) especially those who does houses with "canned designs". However, if someone would be asking how much would the construction of a modest house could be, the safest price to give would be that which made use of SRP direct costs and not the discounted costs or special prices. Dito kase minsan nakoconfuse iyung iba na nakakabasa lang sa mga forum.They'd be expecting that the price given to you would be the price which will be quoted to them when they build their own houses.
10years ago, the most modest warehouse can be quoted with P3,500/sm safely...but nowadays, even the P5500/sm cost for a warehouse can put you into trouble of not completing the project.

Peace.

The guide (12-20K/m2) could give the owner a guiding figure when they themselves estimate their own house. It will give them at least 80% accuracy and think about their project if they have the resources or not.

A careful owner would take 12K/m2 budget and would not expect much except that their house would be close and safe to the elements.

The dilema of most owners, specially those who cannot finance their project to the end is 'how much they will have to bring out up to the house can be occupied'. The figures given by Tholits will guide these potential homeowners.

what if the house you want to be built is located in a remote town in the visayas? what should guide its cost estimate?

Gaano ka remote? ..syempre maas mataas ang cost estimate as compare sa regular case, you will consider hauling cost (renta sa banka, kalabaw and the likes) lalo na kung tipong tatawid ka ng dagat, ilog o aakyat ng bundok assuming na walang malapit na material source sa site.
