HONORARIOS - Supervisión de obra

May 21, 2022
hello, good afternoon everyone, I am the architect gran cota paredes and in this video I am going to share a bit of my experience in construction and

supervisi

on of works. We have been asked a lot in the comments of the videos if we can make a video talking about this topic So I am going to tell you a little about the experience, remember that this is not what should be done for any reason, no, I am not telling you that things have to be like this, I am only sharing my experience so that you can make it yours and if you It's useful, use it, I'm going to tell you about the first work that I built was a house to see the sky and we built it by subcontracting a master builder, so the first way in which we have built would be if we contract a workforce with a master then so that the master builder helped us the master builder mainly helps us to get people that is his function, not his so this master builder I send you a big greeting, isa Jías we have not worked with him anymore he stayed with the student studio but hey Isaías brought his brother brought his cousin brought the neighbor the master builders well somehow they are very connected with the whole world so they know they know people who works so it is very necessary in construction to have that person who is bringing people to us so how do we work with the foreman, prices are stipulated so he is going to say we are going to say that we are going to give him a concept a concept and a price then that concept It could be a blog placement per square meter, we are going to put here a blog placement unit or paste a blog in this case it was a blog by Jal Creto 11 14 28 but hey, the fact is that you put a price on it, so at that moment I don't remember how to go about it. we were walking 40 pesos 50 pesos mexican pesos remember that we are in mexico do your conversions 50 mexican pesos so with this teacher in that way he gives the rudeness per meter per meter ro linear and so all the concepts linear meter I don't know one hundred pesos linear meter so we agreed on all the concepts that were going to be done from the excavation we don't leave from from the foundation we made a video where we explained the budget of a house then there You can see all the concepts that are so we gave each concept a value linear meters of gala derision always from their placement of block square meters 50 pesos so this transports it we go to every Saturday or every Friday or every Thursday depending on how you want And however you want to pay, no, because many people who do piecework, piecework is paying people for what they do, not per square meter, per linear meter, square meters of masonry. what became of isaías then we began to quantify we began to measure average linear meters of da average cubic meters of excavation l We swam the excavation, paying 80 pesos at that time of 80 pesos per cubic meter, so a list of everything that was done was drawn up and they gave us a cost. thousand pesos of everything that had been done in the week we added 10% that 10% is the

supervisi

on and management of the foreman's personnel and that gave us a total I don't know 16 thousand 500 pesos it is not exact but well the case It is this that at the end of the week what was done is paid for that is why it is the piecework and supervision is paid to the foreman you have in charge and also because of the issue of personnel management of moving people so in the end it gives you this cost this cost we are going to add the supervision of the construction architect or the construction engineer whatever your case is here it is very interesting that we have learned with the works we at the beginning only added 10% plus 10% of construction supervision what is the subject of that The issue with that is that you might think that that 10 percent is useful, the problem is that it is not useful because you have a lot of expenses, you have all the gasoline, you have stationery, well, you have some materials that you have had to buy, in short, many expenses that go reducing your utility but we both in this house or for example at home we did it in the same way at home see we had our master builder we had our list of piecework our duty was paid every week and we sat down with the client every week I sat down with the client with the piecework, I explained everything that had been done, I explained the 10 percent for the supervision of the foreman and then I added 10% for us. 10% so if there is a problem if there is something that did not go wrong and the builder has to absorb it, well, the usefulness that you have left is really less then what we have learned is It should not only be that 10%, but an indirect cost must also be added that can range from the 5% indirect that carries gasoline that carries all office expenses, electricity, rents, everything you have to pay to carry out that job. so that your utility remains free and not then it is indirect there are people who manage it from 5% there are people who manage it in 10 there are people who manage it from 15% so all these percentages are depending on the structure of the company that gives you they build because if your company is small and you don't need it you don't pay rent you don't pay salaries you don't pay many things the indirect is less the bigger the company is going to be bigger the indirect that is going to charge you free of utility then i I advise you who are starting to take out your expenses, at the end take out the expenses of your gasoline, your meals, stationery, printing, plans, everything you need to carry out the work and divide it among the months that are due.

The work is going to be carried out and that cost is going to be indirect, so that percentage of indirect costs must be proportional to the final cost of the work so that your utility supervision is free. we work the cave no sorry in the cave we already did it differently right now I am going to explain what is the advantage of this in this way that the client is very clear what is being spent because every week or every two weeks depending on how you want it to do the client is shown the notes, the invoices, the piecework, all the information is shown so that he knows exactly how much is being spent on his work. seeing diminished is already going to be reduced and also the other problem is that the relationship with the client is depleting a little as time goes by, not because imagine sitting down with them every week a and be seeing how good the marble was already bought this week or the marble floor and it is 200 thousand pesos so you have to give me 20 thousand pesos of a single payment more and it was also bought that same week windows were bought The kitchen was bought so suddenly in a week the construction supervision comes together and suddenly in a week they have to pay 100,000 pesos it is a truth to be told so it is difficult for the client and it is also very difficult for them to accept that you earn a percentage of all purchases that are made imagine that suddenly the customer says hey open me up I dropped some money and I'm going to buy better quality air conditioners or I'm going to buy a better quality floor I'm going to put wood on it or I'm going to cover walls with wood In other words, he will be able to spend that expense, it will also be reflected in the builder's profit, not because if the client is going to put 500 thousand pesos more for a Carrara marble floor that is brought from Greece, then the architect is going to earn from that extra investment that the client wants to give, so these things have made noise to me over the years and I tell them that these are only personal perceptions, it is true, that is, each person builds differently, I tell them a little about the perspectives of the scopes and the scopes so for me that charging the client every time they want to grow something every time they want to invest it a little more caused me noise so in the next work that happened in the cave we decided to build already contemplating a cost of supervision of work from the beginning then what happened there we told the clients your work is going to be in a range of costs per square meter between 9,000 and 11,000 pesos at that time obviously telling them that it could be more it could be less the problem is if you are seeing this this video and you are a potential client of both us and other architects if you are in I don't know if you are in cochabamba in bolivia or if you are in argentina in the chaco you have what and also understand that the costs in a construction are really very variable, we know as architects builders exactly with pesos and cents how much it goes with how much the construction of your project will cost call a mission hospital hotel mention home is very It's very difficult because anything can happen because two nails were no longer needed, they already needed 20 nails and that's for what you want, not for windows, for floors, for plastering, for walls, it's very difficult to quantify exactly, so now we're going to go over there, but it is very important that as a client you know that architecture and construction has this issue that is very variable, it is not like buying a car that the car has already been making 200,000 units so you know exactly how much the car not in a construction or how it is unique it is the first time that you do it you do not really know how much it will cost you when you have already done it and it is a house It is repeated as in these houses of social organizations of the countries, well, you already know how much the house costs you because you have already built it a thousand times, right then, but in single-family homes in unique projects, which is the first time that it is going to be built, really knowing the final cost beware it is very complex so do not bother with your architect when it goes out of budget because nobody really knows how much that is going to cost so in the cave that we did with the clients we said this is not going to cost you that much more or less in this price range then your project that at that time had 380 square meters so 380 meters we multiply it by a cost per square meter of approximately 11 thousand pesos so we say that it will cost 4 million pesos our construction supervision will cost you 10 percent client then you multiply that by point 10 and it gives you 418 thousand pesos, those 400 18 thousand pesos divide them between 12 months, not 12 months that will work for you Carrying out the work then that gives you 34 thousand 833 pesos approximately 34 thousand 800 pesos so that is the monthly payment that we were going to earn for building that house we made some adjustments at the end of the monthly payment I don't remember I think it was around 27 thousand pesos we took It took us 14 months longer to build the cave then, but we wanted to agree on this system with the client to avoid what we had experienced in lacquer at home from sitting down every week and fixing all this that we were saying, so for us it was easier, we agreed, we negotiated In the end, this cost of supervision of the work was stipulated around this amount of 27 28 thousand pesos at that time, so we said this is what we are going to charge you, you will know how much we are going to earn everything else, all the costs will to be full of the cost of the house so we every decade I don't remember if it was every week or every two weeks we gave the client the piecework what was being done with our foreman, because we to the foreman, well, if we continue taking piecework each week, the foreman did pay us with everything and supposed supervision of the work, but that was already completely costs of the house We no longer added construction supervision because that had already been stipulated, so we built that way not a little.

More Interesting Facts About,

We changed the system a bit, we made a mix, we continued paying the foreman for piecework supervision of his workers, but the client, the clients They already charged for supervision at a monthly cost, that's right, that's how the cave was. Everything went well. Everything went well. or hidden defects that are called here in Mexico one year to the client of guarantee if it has a leak if an enjarres failed there and it broke you have to re stop it a little bit and one floor came unstuck we have to give one year of those guarantees after that year and all the expenses are borne by the customer at least here in mexico so that was the way the next work was but then there is another way there is another way to do it We have also been working with this master builder that we did in a remodeling that was based on cost per square meter.
honorarios   supervisi n de obra
What does this mean? We and the master builder agreed on a cost per square meter of the construction that would then be around 1,250 Mexican pesos. So, what do those 1,250 pesos per square meter of labor include? Because in this way, we already avoid the issue of the state, we don't avoid the issue of highlighting every week to be watching and there we tie a cost not that the client can already be Finally, say that the labor of this project as such is going to cost you 1,250 per square meter. Multiply those 1,250 by 12,300 square meters that a work has are 375,000 Mexican pesos.
honorarios   supervisi n de obra
It's going to cost you the labor that includes excavation, soil, cement, rooms, rudeness, walls, crowns, everything that is masonry, in that cost, they did not include structures, so this is when we enter the other issue, which is what where where we began to evolve that issubcontracting we are going to delete a little the subcontracting that allows us to save because we do not have people hired throughout the year so they are only hired for specific jobs so masonry and be careful not all the teachers work like this the masonry gives us a cost per meter square which is this around these 250 pesos so this multiplied by the square meters of construction did not give us this cost 375 thousand pesos so this is what the masonry labor would cost us in this project but we only have to specify well what they are the scopes I tell you everything from the excavations or the cement dallas walls jars of flattened firm walls all that is included that does not include installations does not include plumbing electricity and special installations none of that includes does not include materials at all and does not include any of structures does not include castings of columns seedings of columns seedings of slabs nothing apparent cumulus does not include any structure the structure is separated then the structure goes separately then the structure is subcontracted a German one of the structural plan to quote an engineer and the engineer tells you all the columns and footings of your material project and labor will cost you for this project, it will not cost you 85 thousand pesos, the mezzanine slab, the light on the mezzanine, will cost you 150 thousand pesos and the roof slab will cost you 120 thousand pesos.
It already includes material and labor so you already know that in the masonry labor this is going to cost this amount of 375 and the entire structure, everything that is concrete and steel is going to cost you, well, all this part of the 85 plus 150 135 235 120 355 Excuse me if I'm wrong 355 So you start to take out your games that we call games so the material that must be quantified volumes of materials for the galleries because this is only labor, many times it is said Since it is the same amount that you spend on labor that is what you spend on materials only for general quantities, then multiply this 375 by 2 and it already gives you material and labor, this is only in general, you have to get it right. we have to get specific numbers but well the issue is that we are subcontracting items and so all after this item aluminum or windows or carpentry is subcontracted if you are in Argentina or you are in Spain they are called carpentry to the windows and these things carpentry just like doors closets Many times you cook, we work with a carpenter for the doors and closets and we work with another company for the kitchens, so it is part of our way of working, but if you have a very good carpenter who makes closets and kitchens for you, it can also be but the issue here is that we are subcontracting everything and we are giving costs to the items aluminum aluminum 100 thousand pesos carpentry 300 thousand pesos no If you cook 150,000 pesos, we are talking about a medium-high residential level, which is what we work more than anything in the office, but well, those costs can be adjusted depending on the budget as well, but well, we are dividing by items, so in that way, in the end we It gives a cost and that cost with the clients, well, do not shorten it, a cost of supervision of work is agreed upon, which again you have to count all your indirect expenses at that percentage of supervision of work so that your utility is free and you know exactly why imagine I could be charging 400,000 pesos from this house, I don't know, but if I don't get my indirects right, in reality those 400,000 pesos are not useful, the utility can be up to I don't know half of 200,000 pesos of utility for more than a year of free work, so they are the things that you have to value very well so that you know exactly how much you are earning. or because many people I guarantee you that they work only without earning without really earning money or what they earn is only gasoline to stay true to pay their gasoline to pay their rent to pay their real office costs but they are not having anything left so they have to You always learn to know how much you spend to know how much you earn, well, this would be subcontracting and then, for example, in Ajijic we hired a foreman who gave us a general budget that was not included, since almost all masonry structures, everything we had seen and us but with everything and material and labor then that budget that was around 2 million 800 thousand pesos structure how good to be well already stored we bring a lot of information structure labor this is a young class and I know if you are seeing me I don't know where this is a university to me at no time did any teacher tell me this or perhaps if in the control class and it is almost the fails then perhaps it was for that reason then labor structure what it includes then apart from this well and all the other items that we mentioned added to this we must add all the other items but here the interesting thing is that this builder to us He told us I build you in those two 800 what happened that it came out more as often happens then one of the lessons here is that when you are going to subcontract you have to make true contracts and work with very trustworthy people because if you hire one by one person I don't know who doesn't have a degree or who isn't an architect who isn't an engineer because you start to have risks I'm not saying that there aren't people who don't have a degree and who are simply contractors who work very well the issue is that as a client as a client both architect as a real client the one who wants to build for himself the construction business is very dense it is very complex so you need to trust a lot your architect or your contractor but obviously the chances seem to me of working with people who do not have certifications the probability that they look bad on you increases so it is much safer to work with an architect because because you have the security or peace of mind that you are working with the much more serious person who has an established office that is not going to disappear if something happens but certain bad experiences do not stop happening but it is always worth approaching people I trust so here our budget was raised a little and Well, we had to absorb all the clients and we as builders, but well, that's how we work, too.
Right, we contracted based on an established budget, but since we had this experience with this foreman in which the cost rose, we said we have to protect that cost much more. because if one wants to give a raised price, remember that we will give the raised price. We understand it as a cost in which if you give the customer a raised price, you are saying that it will not cost more than this amount in a site. I call the customer a customer, I guarantee you a raised price of two million two million eight hundred a thousand pesos for your construction, I am guaranteeing that it will not cost anything more than that, so in the raised price you must even sign a contract, yes and if so required to guarantee that the price will not obviously rise from the project original all all the extra things that are going to come out in the project are not going to enter into this raised price we mean there may be problems from the top even though it is excavated and suddenly you realize that the earth was bad it was not it was not as good as the mechanics of soils marked it for you and at that moment, an extension has to be made in the foundation, reinforce them, so everything that is not budgeted was quoted in this original budget anyway flush has to go outside the cost of the fixed price but if we say that there is no type of change throughout the development of the project, this fixed price has to be respected then therefore the cost of the fixed price has to be protected and he stressed to us Protected against that Protected against the dollar has already gone up and steel has gone up and cement has gone up and construction materials have gone up any type of external agent that may affect construction the cost of the fixed price has to be absorbed because because that It is not a project change so the client is hiring you in 2018 so that in order to be able to build it in 2019, they have to guarantee a large percentage of 50 to 70 percent of the cost of the work so that you can buy the materials and tying not the prices so that you are protected but the cost of the fixed price has to bring indirect has to bring emergencies has to bring high prices with As we mentioned before, then the raised price if I give the client what the builder gave me for 2 million 800, I can't take a risk with that, I have to tell the client that it will cost you a raised price 3 500 Obviously, that cost must be carefully analyzed, but it is an example, it is not an example, that the client is going to be given this amount as to when we are being given this amount, but here I am absorbing anything that this budget does not include.
In the end the volumetrics were done wrong and they weren't, I don't know, they weren't 100 cubic meters of fill, they were 140 and I gave the customer the cost per meter for a fixed price. absorb us then returning to the subject that a thousand and one things will happen in construction that we do not control or that we do not foresee from the beginning the cost per meter per square meter price of salt you have to contemplate it you have to absorb it er then, but it is something that we have learned that the client likes, they know because in the end what the client wants when they hire a construction company is to know how much what they are going to build will cost, that is, when they start, they believe that the client wants it as cheap as possible, but you are learning more and more that in the end the price is below security and tranquility so I have built for 2 pesos but in the end it becomes 4 pesos and that is That change from building 2 to 4 pesos for the client is when the client gets angry and that is when they despair when they no longer trust one because they think you are stealing from them and I am not saying that many architects or many builders probably do not. they do and that's why we builders have such a bad reputation because we haven't gotten used to becoming professional, so let's not say that we are already so professional, but we are trying to improve processes and n each and every opportunity of each construction that we do, then what we did at casa bonsai and at casa natural was to subcontract the gray work what is the gray work we are going to say that there are three processes in the construction black work gray work and white work the black work is the entire structure is the entire skeleton the shell of the building of the house of what we are building does not have finishes they do not have harris they do not have plastering coatings it does not have facilities it is only the shell we are going to say the skeleton good eye also probably there are people that plumbing installations be included in the black work there are others that are not, so we have to review it in the gray work we are going to say that it is the work without finishes but already with the skin so we are going to call it the skin what does this mean the walls have already finished the blog wall either in a jug it has already been revoked it has already been smoothed it has already been given a cement or mortar coating the floors have already been laid with fi The concrete is firm, the slopes have already been leveled, so you no longer have the work turned off in the rough appearance, looking at the blog, looking at the slabs, the beams, but it already covers it, but with all this layer of paving stones, so that's why we're going to put the skin and the white work well we are going to say that it is the clothes the clothes because it is already all the clothing it already has the floors it already has the paint it already has the stone it already has the kitchens it already has all the clothes to dress the house no longer It already has the windows, it already has the carpentry, it already has the woodwork, it already has everything, so the person is fully dressed and fully articulated, so what we decided in these two houses was to subcontract black work and gray work, so what did we do?
Now we no longer hire we no longer hire this foreman now we hire the engineers who calculated the two projects for us the engineers who calculated the structures for us because we do not calculate structures in this office We subcontracted China, so we gave them the project, they quoted it to us because we also quoted with this other contractor to other people and they gave us a good budget that included black and gray works and they told us it will cost about two million one hundred thousand pesos price then raised for us when making the budget for the final client, the client already saw himself benefited because he already knew exactly how much the gray work was going to cost him because when we made the budgets from house to house to see the sky of the cave they were extremely abstract budgets where that could be from 9,000 to 13,000 and there was nothing to say until here we stopped and this is the cost is what you will get that had good things not because we already mentioned them the client was seeing the progress real but bad things because you don't really know how much it's going to cost so not really knowing how much it's going to cost you obviously it's going to be more expensive but in the end Inal will be grateful for it because it will give you a lot of peace of mind in the construction process and in this case, since they were also bank loans, the bank loans ask you for a work schedule in which you have to tell the bank what month you are going to take what percentage of work to give you a payment ofSo, having a work that is already much more established with a schedule with a work calendar with defined costs gives us a lot of peace of mind with the client and with the banking issue, so this cost is respected in the budget, so we are going to add all the other items windows and carpentry floors plumbing plumbing and electricity we separate them from the cost of gray work because we work with plumbers and electricians from our house who work well for us they give us good costs and those costs the client benefits from them for that reason We separated them so that the cost of gray works would not increase, we separated them on the other hand, which are also things that probably, perhaps, in the next work we will mix them because it can also make noise for the client, hey, why are you charging me separately for plumbing and electricity? separated from the cost of the gray work, then they are things that we are learning again and we believe that it will improve the process to include everything even if this cost increases, but the client is already calm again and no longer feels that it is increasing, not because the construction problem is that the client feels that each time it increases and increases and The cost increases and you do not know when it will end if you give the client a cost at the beginning if you want 30% higher than what you would have said at the beginning but to guarantee the final cost, believe me that the client will prefer it in the end These are things that I am learning along the way, so the client was given an estimate where your client is told, you can rest easy because 2,02,100,000 pesos will cost you even the skin of your house, right from there if you want to put ceramic floors or marble floors or engineered wood or laminate floors if you want to put architectural aluminum or Spanish line or pvc line if you want to put the kitchen with quartz or granite if the qu Are you folk or if you want it in melamine, that is, all the different finishes that you want to give it, the client will control them. bonsai we quote with one another with another and the client is choosing the finishes obviously we do all the design of this we give the proposals the different possibilities but the client will know exactly how much it will cost how much it will cost each provider so in the end, well, this is going to give you a cost, I don't know, four and a half million, depending on everything that is coming out, depending on the finishes, but we are always tying that cost and in the end we are going to give it again what we did in the cave a work supervision cost client this house is going to be built in a year we should not take any longer and we are going to charge you I don't know 22 thousand pesos I think that was what we charged 22,000 pesos per month for the supervision of the work of this project, so we take care of coordinating the engineers, the aluminum subcontractors, the carpenters, we execute all the plans that are needed throughout the work because there are always changes, so a plan or that anything is needed we here in the office are doing it we are coordinating the visits from the banks we are coordinating the estimates with the clients the estimate of the progress that was made in the work is given to the clients every week what has been done spent what remains to be spent then in this way we are making the projects and processes more efficient and we are becoming more and more professional so the client knows how much we are earning no because many of the problems with clients is that they do not know how much architects earn then suddenly they say that the architect is winning the cement is winning the nails is winning everyone and that is what something is something that we have never liked from the beginning what customers feel we are earning from whatever we buy we prefer that the customer knows exactly how much we are going to earn even if he thinks it is little Or you think it's a lot but my architect already knows that for building me in my house he is earning 300 or 400 or 500 or a million or whatever you want but he already knows how much he is going to spend and he knows that we are not going to earn a penny more than that because all the discounts we have agreements with lines of bathroom furniture floors or faucets so all the discounts that we give us we try to transfer them to our customers so that the savings are seen and they benefit from these discounts Because we are guaranteeing our profit, we know that with that amount we are already withdrawing indirect, we are already left with the amount that we see as more convenient, so This is how we are currently working at the company right now.
It seems to us that up to now it is the way in which everything is going better, the clients are a little calmer, we are a little calmer because the execution of the work is also The structure is being carried out by the same engineer who calculated the work, so that gives us a lot of peace of mind. We are supervising the work and we are coordinating the work that is going to be carried out and the supervision, because sorry about the work, in the white work, because we, well, have to enter with all the subcontractors the engineer ends up in gray works and we completely enter white works this is how we work I hope this class is useful to all those who are starting to all those who are already working if you work in a different way please comment how you do it, it's better that it works better, how long have you been doing it, I think that this channel is not for that So that we all get rich, let's share our experiences, both positive and negative, because in the end we're all going to look good and we're going to see the benefits of all this collective learning.
I'm the architect, Abraham against walls. See you very soon.
