Building construction companies

The realization of a building project involves a set of stakeholders who provide their services during the design, administrative procedures, the conduct of the site, the implementation of the various elements that will constitute the building and the receipt of the book completed. We can distinguish the project management stakeholders who provide technical expertise and the companies that carry out the actual work, earthworks, structural work and second work.

The stakeholders of the project management

Any construction or rehabilitation project requires the supervision of a project manager, project manager of the construction of the building to serve the client.


A key player in a building project, the architect is the designer of the architectural project for design, rehabilitation and integration into the landscape. The architect carries the legal guarantee of conformity of all the elements of the project, his participation is mandatory for the design of the plans.

Most often, the architect is also competent for other design missions (urban planner, landscaper, interior designer) and acts as project manager for the execution of the construction site and the management of the interventions of the companies. Only legally authorized to design a building, the architect is the only one and the best able to manage a complete mission of building construction, from design to delivery.

Town planner

Spatial planning specialist, he collects and analyzes data relating to the terrain and the natural and urban environment. It offers management solutions that comply with administrative guidelines and allow construction in the best conditions.


Specialist in the development and design of the natural setting, he intervenes in the external parts of the project, gardens, green spaces and valorization of the ground and its vegetation.

Interior designer

Specialist in the interior design, the interior designer intervenes on ergonomics to increase the functionality of the building and the aesthetics of materials and colors.

For projects of large size and / or complexity, additional expertise may be required to assist the client and / or assist the project manager.

Design office

Specialists in a particular technical field, they bring their expertise to ensure the respect of the technical standards and the reliability of a specific element of the project (structure, fluids …)


Specialist in the determination of the costs of operations, the economist estimates the costs during the design, controls the respect of the budgets during the interventions of the companies, and checks all the operations.

Expert surveyor

Expert in the geography of the construction site, he prepares topographic leveling and boundary plans and conducts field surveys and buildings. It is exclusively authorized to delimit land.

Public works companies

Earthworks: leveling the ground, digging trenches for the foundations.

Roadwork and various networks (VRD): servicing of land for vehicle access, connection to electricity, telecommunications, and water and sewage networks.

Building companies

Structural work: stability and solidity of the building

  • Demolition
  • Foundation
  • Masonry
  • Reinforced concrete
  • Metal frames and frames, concrete or wood

Second work: water / air tightness, aesthetics and comfort of the building

  • Roofers
  • Plumbers-Heating Engineers
  • Electricians
  • Carpenters, fitters
  • Plasterers
  • Iron workers
  • Locksmiths
  • Painters
  • Glassmakers

Other specific stakeholders may also be responsible for monitoring and controlling the site to ensure its smooth operation.

Technical controller: contracted by the contracting authority to control the regulatory compliance of the materials and the strength of the structures.

Health and Safety Coordinator (SPS): charged by the client to implement prevention principles to ensure the safety and health of workers on the site.

Site coordinator: charged by the project manager to coordinate the various interventions and the management of the planning.

Finally, the services of specialized companies can also be contracted according to the particular vocation of a building: stenographers, decorators, cooks, restorers

10 steps to select the right builder for your needs

Selecting the right building company according to your needs and for the type of new house you are looking for is one of the most important decisions you will make in the process of buying your home.

Fortunately, there are some proven ways to speed up the research and selection process, and help ensure that you find a quality builder that is the ideal choice to build your home.

In all, this tip can speed up your search for a construction company and increase your confidence in that decision.

10 Steps to select the right builder

  1. Define your needs: What size, type and range of house prices do you need?
  2. Experience tells: Although every builder was once new, experience matters.
  3. Are previous buyers satisfied? Request and verify references from previous buyers.
  4. Verify that the builder or building company is licensed (as appropriate) and is properly insured.
  5. Does the design fit? Does this builder have experience in the style of home you are looking for?
  6. Guarantee and service: How does this constructor work in each of these areas?
  7. Resale value: Have the previous houses of this constructor maintained or increased its value?
  8. Participation in the industry: Is the construction company a member of the local association of builders?
  9. Tour models or houses of clients: There is no substitute for this step.
  10. Look for signs of quality: As for labor, materials and practices, when you walk through these houses.

Here are some additional details about the steps above:

  • Define your needs

Although some builders build a wide range of houses, many also specialize in a specific type of house, price range or style. For example, not many companies build homes to start for homebuyers for the first time, and neither do multimillion dollar homes for wealthy home buyers. Building materials, specialized contractors and even the construction process can differ greatly depending on the type and price of the house. Look for something that fits.

  • Experience counts

All of the construction companies, including the most experienced and reputable ones, have ever built their first home. And many construction companies started with experienced veterans from other construction companies. Do not discard a new company in advance, especially if your team includes experienced professionals, but look for experience in general and the type of home you are looking for.

  • Are previous buyers satisfied?

Many builders offer customer referrals. If not, ask. In any case, follow up. Some questions that would be good to do: Would you buy another house from this builder?  And do not forget to ask the main reasons why a former buyer would recommend or not a construction company.

  • Is the builder licensed and insured?

Not all states or areas require builders to have a license, but be sure to work with a licensed builder if required. Ask about what insurance the builder and the specialized contractors have. Make sure they and you are covered during the construction process.

  • Does the design fit?

A builder whose portfolio consists exclusively of contemporary homes may not be the best choice for that traditional home you are looking for, and vice versa. Although many builders have experience in a variety of design styles and architectural details, in general, look for one whose work includes at least some examples of the style of home you want.

  • Warranty and service

One of the main advantages of new constructions is that your home itself and most of the products, systems and components it contains are new in package and are under warranty. The peace of mind that provides knowing that major repairs or a new roof are probably years away is important. In addition, it seeks a structural guarantee of ten years or more on the house itself, ideally transferable to a new owner in case you sell. Also look for a construction company that provides timely and courteous service under warranty and that take the time to explain the maintenance and proper care that any house needs.

  • Resale value

Good reputations follow good builders, among homeowners and realtors. Look for builders whose houses tend to maintain their value. We know that in recent years the value of housing has fallen a bit for one of the first times in history, because of the market. So this is not an exact science, but when you see that a builder’s houses maintain or increase their value, it’s a good sign. You should also look for ads for real estate agents that specifically mention the name of a home builder for a sale that is already five or seven years old. The real estate agent evidently sees the brand as a great added value.

  • Participation in industry

Not every good builder chooses to join their local home builder association, so do not overemphasize this. However, such membership tends to show that a builder is long-term committed to that area. It is also a sign of commitment to the developers of new home communities, construction products suppliers and specialized contractors working in your city or town.

  • Visit model houses and/or houses that this builder has done for buyers in the past

Once you’ve narrowed down your options to a list of possible builders using these criteria, this is the most important step. Nothing replaces seeing personally houses built by a builder or construction company on your short list. It can be a furnished model house that is open to the public. Or it can be a house built by the builder for a former buyer that you can visit with an appointment. In any case, pay close attention to the look, feel and quality of the house.

  • Look for signs of quality

Look for signs of quality building and attention to detail when you visit these homes. Consider also the construction products that the builder uses. Are brands that have earned a well-deserved reputation for quality? What about the houses under construction you went through when you were on your way to see the finished model house? Were there signs of care and attention there as well?

Finally, observe the quality of the people who work for the construction company. Did the employees show sincere interest in you and your needs? Did you listen carefully? Did they give you good answers to your questions? Were they courteous, timely and professional in your interactions with them in the model house, sales center or office?

With the steps above, you will be well on your way to selecting a good builder that is a good fit for you, your needs.

Construction budget

For construction, we will say that it includes a complete list of all items of the work valued, including all the activities of this, from its inception to its term, according to the requirements of, “Technical Specifications of Architecture”.

In a total budget of work includes assessing all the requirements indicated in the “Technical Specifications of Work” (Architecture, Structure, Sanitary Facilities, Gas, Electricity, specialties, etc.):

  • Construction Budget = Direct Costs + Indirect Costs = Total Cost of Construction + VAT (Value Added Tax)
  • The Direct Costs are: The sum of the following costs.
  • Preliminary Works + Heavy Construction + Completions + Sanitary Installations + Gas + Electricity + Specialties (Heating, Automation (Domestics), etc.) + Exterior Works.
  • The Indirect Costs are: The summary of the costs of the General Expenses + Utilities.
  • The “Preliminary Works” are all those works that as its name indicates the ones that are required and are previous and necessary at the beginning of works. (Clearing, fences, installation of works, bathrooms, basic sanitary facilities, etc.)
  • The Gross Work are all those works that contemplate the structure of the work. (Excavations, Foundations, roof structure (trusses), walls, etc.)
  • The Terminations are all those works that, as the name implies, give the structure its finish. (Decks, pavements, coverings, artefacts, doors, paintings, etc.)
  • The works of installations are those works that provide water, electricity, heating, controls, etc.)
  • The Exterior Works are those involved in accessibility, gardens and perimeter walls, fences, etc.

 Summing up a construction budget is the sum of:

  • Direct costs more
  • Indirect costs.

The direct costs comprise an itemized which should break down all the items of a work, which are represented and indicated in the Technical Specifications of Architecture, which are valued and these total the Direct Cost of work.

Indirect costs is the sum of the General Labor Expenses and the Profits or benefits.

To this sum is added the Value Added Tax (VAT) and we are against the Total Cost of Work.

Now where between the studies of publications, in the quantities that each item has that conforms the itemized. Where each item has its unit of measure, its quantity and its unit price.

The publications are the calculation of the quantities of these items.

Buildings construction

A company that may seem simple to the buyer but represents a real technical, administrative and commercial challenge for the developer.

Between the sale of land and the delivery of an apartment, what is happening? What are the main steps that allow a residence to see the light of day? How is the buyer involved in the project? Decoding of a building construction in outline.

  • The choice of the site

First step, the choice of a field. The presence of infrastructures, services, shops, liberal professions, transport is essential.

Proponents are also trying to find locations with as little nuisance as possible. Green spaces will be a real highlight. The region will be a key factor in launching the project. Elsewhere, where the market is mostly driven by investors or competing with the individual house, “we are more cautious, we want to be sure to market our programs.”

  • The feasibility study

The building permit is not easily obtained. The mayor and the local authorities will have to approve the project. The proponent must therefore carry out an analysis on the urban plan to know what it is possible to do in the municipality according to the architectural, environmental notebooks … It must gather technical data, on the ground for example with a geotechnical study. We see if we have to do a demolition, we study the history of the site to know if it is a former industrial site or not, whether or not to consider cleansing the soil which implies not insignificant expenses from a financial point of view.

At the same time an architect studies the feasibility of the building: its shape, its position … It is then that are defined more precisely the typology of the apartments and the percentage of studios, two rooms, etc. which will be built, which will determine the architecture of the residence. The developer asks the architect to develop his project according to the destination of the property.

  • The preparation of the commercial launch

The determination of the price. At this stage, all the technical elements are specified. The methods of construction, the thickness of the walls, the positioning of the ducts, the location of the exterior joinery, the surface of the terraces and balconies …. This makes it possible to precisely define the exit price of each apartment.

We weight the plus and minus of each apartment according to its surface of course but also according to its floor, its orientation … The additional surfaces are also taken into account during the establishment of the price. For example, underground car parks are more expensive.

At this stage, the land is not bought: it is still at the stage of the promise of sale. It is only once the credits obtained from the banks and the license purged that the land is bought. But the banks only grant these loans when the marketing is already started. “It varies from bank to bank, but they generally require that we have sold 30 to 50 per cent of the units depending on the location,” says Paul Jaquan, founding president of Reid. “Our visibility is low during the assembly phase, there is always a risk that the building does not see the light of day.”

However, the project is becoming more precise at this stage and all the teams of the promoter are working together.

How to sharpen teeth grinder stump

Grinders stump helps remove stumps from trees. This is done with sharp teeth that spin and grind through the strain until it can be removed by hand. Like any tool used to cut, you finally have to sharpen teeth grinder stump. The teeth should be removed from the stump grinder and sharpened individually. This process is done with a standard bench grinder and a special diamond grinder disc. The whole process can be completed in a single afternoon.


  1. Remove the teeth from the stump grinder. Use a screwdriver or hex wrench to remove the mounting screws for each tooth. Remove the tooth. Refer to the instruction manual for your particular model for additional instructions if necessary.
  2. Put on mask shield and dust. Fill the container with water and place it within reach of the bench grinder.
  3. Turn the mill. Allow the grinder until it has reached full speed.
  4. Retention of the tooth grinder stump to the diamond wheel of the bench grinder. Keep the tooth at an angle that matches the original contour of the cutting edge factory.
  5. Pressure Apply slowly moving the tooth back and forth laterally on the face of the wheel. The pressure of the roller from one edge to the other for the edges and the corners of the camber. Immerse the tooth in water every two to three minutes to cool the metal and avoid damaging the wheel or tooth. Repeat for each tooth.
  6. Insert the teeth back into the stump grinder and secure them with the mounting screws.

Construction project management

Currently, most of the problems arising in the construction process are a consequence of poor management and the inability of the leader to organize and plan the activities of his staff, which undoubtedly leads to high construction risks associated with the lack of the ability to complete construction on time, as well as poor quality of the constructed object.

In order to avoid the occurrence of such problems leading to loss of money, in most cases, it is necessary to skillfully manage the construction process or hire a qualified specialist in this field, capable not only of exercising full control over the construction documentation, but also organizing the construction process, clearly acting in accordance with the building plan.

Methods of managing construction projects. In the event that all the necessary documentation has been collected and a permit has been obtained from the state for construction work in a certain territory, it is necessary to clearly develop a management plan for the construction process in order to meet the deadlines and not exceed the available budget.

It should also be noted that there are a lot of different ways and methods of managing construction projects, but this article will consider a method that allows to minimize any kind of construction risk, as well as to meet the deadlines.

The first stage of project management is the classification of the project, the construction of which will be carried out. Further it is necessary to carry out a detailed analysis of all investment options, as well as to develop a budget plan. The third point can rightfully be considered the analysis of risks, the occurrence of which is possible in the process of construction, as well as drafting a business plan to avoid them.

After all the above points have been fulfilled, it is necessary to perform a calendar calculation in order to clearly indicate the time after which the construction object should be ready.

It is also worth paying special attention to the procurement and supply of building materials.

An experienced leader, before signing a contract with a certain supplier, should carefully analyze the entire range of regional construction markets and choose the most profitable offers that can save the budget as much as possible. The best option in this situation is the waste of fewer funds than indicated in the budget plan. The remaining funds will be some kind of insurance in case of acquisition of low-quality building materials or occurrence of extraordinary incidents requiring additional investments.

It should also be noted that the best option is to cooperate with a well-known supplier of building materials, which has proven itself in the market. In conclusion, we can say that the choice of a successful method of management of construction projects will minimize any kind of risks, meet deadlines, and keep within the budget.

Construction of ecological and self-sustaining houses

The construction of ecological houses today is a practice that is increasingly recurrent. The construction of ecological houses, besides allowing a significant saving in the economy of the families, also allows to contribute in the improvement of the environment.

  • Construction of ecological houses

The construction of ecological houses involves a series of elements from different industries, from the use of recycled construction materials, ecological and energy-saving household items , the use of tools in the construction process that have been developed with materials that are more sustainable and energy-saving, the use of solar panels easy to assemble, even the orientation of the house according to the daylight hours to take full advantage of it.

Although it is true that there are important obstacles, such as the price of certain types of building materials, we can also find cases of successful green home construction projects in which recycled materials have been used.

But if you want your home as well as ecological, self-sustaining, you can resort to ingenious energy production systems such as solar panels, capture rainwater and reuse both this and the waste you generate, which in a lifestyle ecological, must also be minimal.

The construction of ecological houses as well as promoting the self-generation of electric energy and the recycling of materials and an intelligent use of those included in the eco-friendly habits, try to minimize pollution by energy expenditure while in turn achieving a economic saving.

  • Aspect to be taken into account in the construction of ecological houses

Since there is no single model or method of building ecological houses, we will share a series of principles that will help you design your own project to achieve a self-sustaining home and energy independence and even food if you decide to set up a small garden and take advantage to the maximum all your consumer products.

Generally, building green and self-sustainable homes requires a high budget if you want to invest in household items with modern technology, but in a very short time you will recover the investment made by saving energy and other resources.

At the outset, if you want to reduce the consumption of electricity and also generate it, heaters and solar panels are a widely used today, even if you live in cloudy or very humid areas, as some solar panels have technology that allows to capture solar energy even on cloudy days.

The house has to be isolated making use of sustainable materials, such as the traditional adobe used in many of the buildings that today is still observed in the towns and even in the middle of the big cities and that stands still, showing its great durability.

The construction of ecological houses with this material, besides being simple and economic, presents many other advantages that make it attractive to achieve environmentally responsible housing. This is a material that has been used for millennia (there are records of constructions around 8,000 years BC) in various parts of the world where conditions were given. Even today it is widely used in many parts of the world in the construction of modern ecological houses.

Another aspect that reinforces the lining of the structures of the house is the installation of green roofs and vertical gardens on facades and also in the interior of the house

One more way to make the most of natural resources in the construction of ecological houses is the solar orientation and the function of climatology (more or less wind, rains, temperatures, etc.) throughout the year.

To know the angle of the sun you must get a solar card, you can download the application for is and Android, it is a scheme on the route of the sun to know which part of the facade will receive more and less sun. The layout of the vegetation in your garden will also benefit by taking that important factor into account. With this application you can know in real time where it was, where it is and where will be the sun.

Once you have decided the location of the house and its orientation, you must make an intelligent distribution of windows, doors, windows, porches, terraces and other elements and materials as required for greater or less isolation in different areas of the house.

Construction of social and domestic buildings and structures

The construction of social and household buildings and structures is a construction that is checked with special care and attention by the supervising and supervising bodies, all ranks and organizations.

Not allowed, any violations, at all stages of construction work. In addition, social and household buildings are usually put on for a longer term warranty period.

The construction of social and household buildings, including schools, colleges, polyclinics, kindergartens, etc., is a special kind of construction work, for which not every organization will take.

The general contractor takes full responsibility for all the stages of construction, exposing its own supervising units and engineering staff who will optimally distribute the forces of the contracting organizations, guaranteeing the production of works, according to the schedule.

Not an unimportant role, the selection of building materials also plays. It is important to find not the cheapest material, but fully complies with the norms of the FEZ, fire safety and having a complete set of documents, such as a certificate of compliance, laboratory conclusions. Only with the confirmation of all norms, the material is delivered to the building site.

The work, on such objects, implies a very large workflow. This type of work requires seriously trained specialists. According to the staff, there are accountants, engineers, suppliers, surveyors, own technical supervision and other employees who have accumulated a lot of experience and who constantly improve their qualifications.

General contractor organization, guarantees one-man management at the construction site and full compliance with the production plan.

One of the main articles is a unified financial control, which completely excludes over expenditure, allocated cash. All financial documents are subject to multiple checks. Constant monitoring of the building materials market is carried out and sometimes cheaper material can be chosen, but not inferior (or sometimes superior).

Construction economist

What is he doing concretely?

The activity of the construction economist is characterized by interventions at all stages of construction.

At the project design stage, he/she calculates the project’s budget, drafts summary and detailed specifications, and the quantitative pre-metric, participates in the financial structuring of the operations.

At the stage of business consultation, study and price quotation, procurement, he/she writes the written documents of the business consultation file, participates in the examination of the candidatures of companies , prepare the framework of acts of engagement, draft the special administrative clauses, prepare the tender documents, analyze and compare the price offers of companies, research and negotiate possible savings.

At the stage of the realization, he/she can be brought to assure various tasks:

  • establishment of the provisional budgets and the schedules (manpower, material supply, provision of the material …)
  • scheduling of the works,
  • supervision progress of work,
  • general coordination,
  • acceptance and control of works,
  • control of costs and yields,
  • analysis of results,
  • development or correction of statistics and ratios.

Construction price

Building a house is expensive! We have to compare the different offers of entrepreneurs, yes … but on what basis?

  • Reading price tables

The prices mentioned must be interpreted with the necessary caution. These are indeed averages and therefore not absolute values, which have to be adjusted according to the differences which may occur in the materials market and the costs of labor. The specific circumstances of each site must also be taken into account.

For example, work in a city causes many more problems and costs: accessibility is more difficult to bring materials, there is no room for storage, and sidewalks have to be rented from the commune. Prices are often 15 to 20% higher.

The unit prices for renovation are 20% higher and sometimes even higher.

  • Measuring quantities

Many contractors and even some architects are unaware that there is a Belgian standard to correctly calculate the quantities for the work to be carried out.

It is mainly the joiners and the ceilings which do not deprive themselves of “to put back a layer” and decide unilaterally to count everything and therefore not to deduce any opening.

In addition, there are also masonry contractors who set a price for a “mixed masonry”. Under this item, they indicate a unit price for the entire exterior wall, without dissociating facade brick, insulation and supporting wall! For them, it’s easy to calculate, for you, it’s impossible to control
