BIM Adoption warning on the Construction Industry

Even though the adoption of BIM has improved in countries like India, its full potential remains untouched. BIM can be utilized in a country like India to scale projects and attain an attractive cost to benefit ratio because it has a vast talent pool and access to BIM.

The industry has a fertile opportunity to transform itself using BIM. Change in how work is done, hiring new people who understand technology, and making technology an integral part of the overall strategy are required to achieve this.

Although companies recognize BIM’s role, the ground reality is more complex. As strong proponents of BIM, we recognize that we need to understand the obstacles and perception gaps impeding its growth before we can evangelize this technology.

Training & Talent Lacking

Recruitment of skilled workers is a challenge for construction companies. That is primarily due to the industry’s conventional image. Flexibility is important to millennial & they prefer companies with an obvious technology focus.

As millennial will make up 75 percent of the AEC industry in the next decade, their expectations and perceptions of the industry will be mismatched. Buildings are considered rigid & office spaces are also not as glamorous as those in Information Technology.

Gender diversity is also low in the industry due to its perceived male-dominated nature.
Adapting BIM is challenging for companies due to a lack of talent, training, and contextual awareness. Fundamental processes and working ways will need to change for construction companies. Customers and employees will expect this from you as you strive to keep up with digital developments.

Unrealistic Expectations & Scope

Many others deliver projects and walk away without offering assistance to the company as they indulge their digital ambitions.

The scope of BIM implementation is often not defined by companies. Overpromising and setting unrealistic expectations are common problems with some partners. BIM must be implemented in a way that aligns partners’ goals with the needs and expectations of clients for long term sustainability. If you limit BIM to a limited number of projects, it becomes an experiment.

Enthusiasm Problem

In some cases, BIM adoption has been delayed since there was not enough demand. BIM may not be a priority for small companies. Companies do not consider it to be relevant to project completion since there is no compulsion to use it. We need to make BIM’s benefits clear if we want it to be prioritized by companies.

Fire Risk Reduction in Construction

The purpose of construction sites should be to bring new things into the world, not to destroy them. Nevertheless, it is not always the case that this is the case. In the event that construction professionals are not careful, fires can break out on site, seriously jeopardizing the safety of workers and causing severe loss of time and money to the project.

There are an astonishing number of simple and common risks which can cause fires on construction sites, including electrical equipment like powered hand tools and generators, flammable or combustible materials like gasoline containers, or combustion engine equipment like excavators, which can cause fires on construction sites.

Is there anything that construction professionals can do to prevent fires in the workplace and ensure their sites are fireproofed and safe? The following are six strategies you should follow for prevention from fire.

1. Know the best and most effective

In terms of electrical best practices on construction sites, there are a few things that need to be taken into account. Use only fuses that are rated appropriately, for example. Extension cords should never be used as a substitute for wiring improvements that are required. There is always a risk of fire in hazardous areas and wiring, so it is always a good idea to inspect these areas. As well as this, it is important to make sure that electrical equipment is properly grounded or double insulated before you use it.

2. Ensure that all permits are in order

Ensure that all necessary permits are obtained before the construction of the next project is started in order to ensure that the work will be done safely. If you are planning to work with an open flame or produce heat or sparks in any way during the process of a project, then your project requires a hot work permit.

In addition to welding and brazing, cutting and grinding may be necessary as part of this process. The permit must be present in order to ensure that there is no possibility of a fire breaking out in the case of a fire breaking out.

3. Always have a plan

It is still possible for a fire to occur even with the best protection. In order to prevent a fire from spreading on a construction site, it is important to have a clear, detailed plan in place when a blaze starts. All workers on a construction site should know how to evacuate, how to alert others in the event of an emergency, and how to take a headcount if there is a problem on the site. Keeping a head count is particularly critical since it ensures that all members of the team have successfully left the building and are out of harm’s way. As part of your emergency plan, you should also make sure that you have a person who has been designated to call 911 and summon fire professionals to the scene if there is an emergency.

4. Despatch Fires and Extinguish Flames In a Timely Manner

There is no point in investing in a fire detection system when all that is required are employees’ eyes and noses. There should be a fire alarm system installed on every construction site so that workers will be alerted if a fire occurs. The construction site should also be equipped with a fire suppression system, which could be either overhead sprinklers on commercial sites or smoke alarms on residential properties, that will be triggered or turned on automatically in the event of a fire.

A sprinkler system is a simple and effective method of extinguishing a fire quickly and minimizing its overall danger. Last but not least, make sure there are portable fire extinguishers throughout the site that are ready to use at any time and that are regularly inspected and maintained.

5. Maintain Safety with Portable Heaters

Please ensure that all necessary precautions are taken when a contractor plans to deploy portable heaters at your next construction site if that is the case. It is true that portable heaters keep a space warm, but they can also cause fires in the area if they are not used properly.

You should ensure that any heater you use is protected against tip-overs, that is, that it automatically shuts off if the unit falls over if it falls on its side. Furthermore, you have to be careful not to place the heater too close to any combustible material that may be present at the worksite as that may result in a fire.

Corrosion and its Types

What do you mean by Corrosion?

As a native process, corrosion is the process of converting pure metal into a much more robust and robust form such as oxides or hydroxides. There is no doubt that it is a constant of metals because of the artificial action with which they are enclosed.

During the course of the process, it degrades and erodes the metals, thus destroying their power, beauty, and durability. It is common for materials to be divided into two categories, which are chemical factors and physical factors, as a general rule.

Varieties of Corrosion

Crevice Corrosion

Corrosion in crevices occurs when there is little space and interval to produce liquid and there is no suitable body process to process it. Whenever crevice corrosion occurs, it adds a great deal of risk to the chance of crevice corrosion occurring in the near future. Because of the connective sign between the metallic floor and corrosive fluid, crevice corrosion will be damaged by the mechanical injury resulting from the mechanical action of the fluid.

Corrosion Fatigue

Fatigue of ore will grow in a corrosion climate, and then it will be called corrosion fatigue, meaning the defeat of matter due to repeated application of pressure. There can be a development of this condition if the fatigue resistance of a metal is stopped.

Galvanic Corrosion

A galvanic pair is formed between two types of the matter when they situate and connect in corrosive potassium, and it is the anode and cathode that form the galvanic pair. It is necessary to be in electrical contact with an electrolyte for galvanic corrosion to occur.

Environmental Cracking

Cracking under the influence of environmental conditions refers to corrosion that occurs as a result of a combination of ecological conditions damaging the material, along with synthetic, pressure, and strain-related outcomes that can actually occur simultaneously.

There are three types of corrosion in the environment below: corrosion fatigue, hydrogen-induced cracking, stress corrosion cracking, and liquid metal, embrittlement, and stress corrosion cracking.

Intergranular Corrosion

A form of corrosion called intergranular corrosion occurs when corrosion appears on the granular field, and in this case, the seed is not damaged. It is evident that there is a variation in a reaction against a pollutant when both the original source and the seed margin are different.

Uniform Corrosion

Corrosion will produce a uniform coat of corruption on the floor in the form of uniform corrosion. Basically, this kind of corrosion is caused by the unrolling of the material over the entire bottom of the materials and this kind of corrosion is abroad in spots on materials that are not safe by the floor layer such as AL, Zn, and margin will include a few materials that are generally damaged by uniform corrosion.

Retainage in Construction : Merits & Demerits

During construction, the construction contract governs the project. This document is a written record of the agreements between the customer, contractor, and subcontractor. The contract specifies the materials to be used, the timeline for completion, and the construction method and payment date.

Customers may withhold a small amount of money until the work is completed in payment terms. This withholding is called retention, which becomes important in construction.

Define Retainage

A retainage is a portion of a contractor’s fee that is withheld until the project is completed or specified in the contract.

In essence, retainage ensures that contractors and subcontractors fulfill their contractual obligations in a satisfactory manner. In the absence of retainage, a customer might pay an untrustworthy contractor their full fee upfront, at which point they might abscond with the money and abandon the project. A retainage serves as a reverse security deposit for the customer.

Retainage Workflow

A retainage percentage of between 5 and 10 percent is generally agreed upon by the parties before the start of the project, and stipulated in the contract. As the construction project progresses, progress payments are made periodically as fractions of the full fee.

An example of a retainage calculation would be $100,000 if the project price is $100,000, along with a 10 percent retainage. Each progress payment is subject to a 10 percent retainage by the customer or project owner. Each progress payment of $100,000 stipulated in the contract will be withheld by $10,000 by the customer.

Define Substantial Competition

As defined in the contract documents, substantial completion occurs when the work or a designated portion of the work is sufficiently completed so that the owner can occupy or use it as intended. A property has been substantially completed when the owner is able to move in or use it for its intended purpose, and retainage to the contractor is likely due.

Merits of Retainage

Financial Security

Money held in retainage allows the owner to preserve some funds that might have otherwise been wasted on an incomplete project when a contractor or subcontractor fails to perform their obligations. This money can now be used by the owner to hire another contractor to finish the project.

Proper Incentive

Construction contractors and subcontractors will be motivated to perform their work well if a significant part of the overall project fee is not released until the structure is usable.

An Overview of the use of Sandbags in Cofferdams

Cofferdams are short term arrangements to support the building activity behind logical waterless situations. Sandbags are simply bags filled with sand and bricks. In these sandbags, a cofferdam will be formed, which will be known as a sandbag cofferdam. It is in this process that void bags are equalized according to requirements.

A mixture of bricks and sand will then be used to cover the area. Despite the presence of dissolute water, a sandbag cofferdam is able to resist it. Since sandbags also have parallel faces, the slope of the coffer dam is very steep.

Define Sandbag Cofferdam

It is a short term design that supports the building activity behind the apparent waterless situation. This is nothing more than a bag covered in sand and bricks. A sandbag cofferdam will be created using these sandbags.

The void bags will be equalized as needed in this process. A blend of bricks and sand is then used to cover the part of the structure. As sandbags also manage a parallel face, the slope of the coffer dam is extremely sharp. The water will not dissolve the sandbag cofferdam due to its strong resistance to dissolution.

Dewatering Problem in Sandbag

1. The process of making sandbags requires a great deal of time.
2. More labor was required for sandbagging.
3. Inclines will be difficult with sandbags.
4. More dirt can be removed with sandbags.
5. The longer the sandbags last, the worse they are.
6. In the event of flooding, sandbags will be the sloppy solution.

Importance of Sandbag in Single Wall Cofferdam

The inside and outside faces of the sheets are stacked with half-filled sand bags to increase the dam’s stability. Water is pumped out of the enclosed area after the dam is constructed so that construction can begin.

Flood water damage can be prevented or reduced with sandbags, a simple, but effective method. By filling and placing sandbags properly, moving water can be diverted around, not through, buildings.

Sandbags are filled with floodwaters filled with fine particles like silt and clay. In essence, these particles are caught in the sand. Sand is actually made more effective as a barrier by clay and silt filling in gaps.

Alternative of Cofferdam

In spill containment and water prevention applications, Hydra-Barrier is an effective alternative to sandbags. It comes in a variety of sizes, is durable, reusable, can be filled when needed, and can be emptied once it’s uses. The easiest way to store Hydra-Barrier is the way you store sandbags.

Merits of Sandbag

1. It benefits dynamic pile function in this way.
2. The base of each row and float must be found.
3. The platform and base of the piers should be installed, as well as the bolts to hold the platform down.
4. Separate a lake or ocean from a place by surrounding it.
5. An operation platform for water is provided by a construction foundation.
6. Provide a safe environment for conducting base activities.

Merits of Sandbag Cofferdam

Creating optimal working conditions is one of the main advantages of cofferdam construction. It is also possible to significantly reduce the project’s cost by draining submerged work areas before moving equipment and personnel.

Key Materials and Methods for Preventing Flood Damage

Flooding will inevitably occur at some point in your life, no matter where you live. People on the coast are not the only ones at risk from high water. Changing weather patterns and an increasing number of hard surfaces, such as roads & sidewalks, are increasing the risk of flooding among homeowners. It is important to note that disaster assistance is usually a repaid loan.

It is considered a flood damage resistant building material if it can withstand direct or prolonged flood water contact for 72 hours without significant damage.

Use Flood Resistant Materials

A flood resistant building material is non-damaged after being exposed to flood waters for at least 72 hours. In terms of damage, significant means more than a minor cosmetic repair.

Those parts of a home that lie below the 100 year flood level should be constructed with flood resistant materials. Concrete, closed cell, foam insulation, pressure-treated and marine grade plywood, and ceramic tile are all common flood resistant materials. You can also use stainless or galvanized steel hardware in these areas.

Key Methods to Protect Flood Damage

Waterproof Veneer Use on Outside Walls

Regardless of the depth of floodwaters, a home can be severely damaged if water reaches the interior. Add a waterproof veneer to the exterior walls of a home to protect it from shallow flooding. Several brick layers can be covered with a waterproof membrane. Additionally, the interior walls need to be changed as well.

Replacing batt insulation with washable closed-cell foam insulation will prevent flooding in areas below flood level. You always use exterior grade lumber for any wood blocking added inside the wall cavity.

Fuel Tanks Anchoring

Unanchored fuel tanks can easily be moved by floodwaters, posing a serious threat. Unanchored tanks outside a home can be driven into walls by flood waters or swept downstream, causing damage to other property.

Unanchored tanks in basements can be contaminated with oil when floodwaters move them. Attaching a tank to a large concrete slab heavy enough to resist floodwaters is one way of anchoring it. Regardless of whether a tank is inside or outside a house, this process can be applied to them all. Ground anchors can also be used to anchor outside tanks. Straps can be run over them and attached to them.

Well Protection from Contamination

Water from floods can carry hazardous or toxic materials, such as raw sewage, animal waste, oil, gasoline, solvents, or chemicals. It is possible for floodwater to contaminate well water and make it unsafe to drink or use, even after the floodwaters recede.

The casing of a well should be extended at least two feet above the highest known flood elevation in order to protect it from contamination. It’s important to remember that potential contaminants shouldn’t be stored within 100 feet of the well.

HVAC Equipment Utilization

Floodwaters can severely damage HVAC equipment such as furnaces and water heaters. Flood depth and the length of time the equipment remains underwater will influence the extent of damage.

Moving HVAC equipment from the basement or lower level of a flood prone home to the attic or upper level will protect it. There is also the less desirable option of leaving the equipment where it is and building a concrete or masonry block flood wall around it.

Everything you need to know about foam concrete

What do you mean by Foam Concrete?

There are several ways to fabricate foam concrete, but the most popular way to produce foam concrete is by combining a cement paste (slurry or mortar) with a prepared foam in order to generate foam objects.

In terms of the amount of air that is entrained in foam concrete, it can be distinguished from air-entrained concrete in terms of how much air is entrained in it. It is estimated that 3 to 8 per cent of the air is absorbed in the concrete that has air entrained.

Additionally, there is another difference between aerated concrete and retarded mortar which is due to the percentage of air entrained in the concrete. A retarded mortar system is estimated to be 15 to 22 per cent more expensive than a regular mortar system. When it comes to aerated concrete, the bubbles are chemically formed as a result of the aeration process.

How is Foam Concrete Produced?

To produce foam concrete, a dilution of a surfactant in water is used, which is then passed through a foam generator, which produces a foam that is of a stable form that will last for several days. Foam is formed by mixing the cementitious mortar or grout with the foam produced so that a foamed quantity of the desired density can be produced.

A low-density fill is also manufactured using these surfactants. Controlled low-strength materials are also called CLSMs. A mix of low cement content and rich sand is added directly to foam to obtain an air content of 15 to 25 per cent. Some manufacturers supply low-density fillers as foamed concrete, so caution must be exercised. For the production of foamed concrete, there are two main methods:

• Pre-foam Method
• Inline Method

The Pre-Foam Method for Foam Concrete Production

Using this method, the base material is delivered to the site by a ready-mix truck. During rotation, the mixer injects the pre-formed foam into the truck from the other end.

It is therefore possible to produce small quantities of foam concrete for small tasks, such as grouting or trench filling. This method would produce foam concrete with a density ranging from 300 kg/m3 to 1200 kg/m3 depending on the density of the mixture. A 20 to 60 per cent air percentage will be added to the foam input to produce the foam. In order to calculate the final volume of the foam, one has to reduce the amount of other base material in order to reach the final volume. In order to carry out this procedure, a truck is used.

For this method, controlling steady air and density is challenging. It is necessary to specify and allow for a certain amount of under and over yield. The foam is mixed with a cement mortar mixture that has a water to cement ratio of 0.4 to 0.6 when it is created. The foam becomes unstable if the mortar is damp. Pre-foam is challenging to combine if the environment is too dry.

The Inline Method for Foam Concrete Production

A unit is filled with the foundational cement and sand mixture. The mix and foam are properly combined in this unit. The mixing procedure is controlled in a suitable manner. Larger volumes may be mixed easier thanks to this. The inline approach consists of two processes:

A Brief Description of Architrave Building Construction

Classical architecture uses architrave to designate the bottom part of a certain type of lintel called an entablature. In an entablature, it forms the bottom third part of the bottom third of the vertical columns. Usually, architraves are horizontal or vertical moldings around openings, such as doors or windows.

Define Architrave

There are most homeowners who won’t even think about architraves for the rest of their lives. Your doors and windows are framed by an architrave, which is an interior molding, decorative trim. A wall covering enhances the look of a room as well as conceals unsightly seams and joints.

It is common for windows to have architraves. In order to determine how to measure and install shutters on your window, we will need to identify the architrave style.

Architrave Construction Process

Hardwood, softwood, and medium density fiberboard or MDF are the most common materials used for architraves. Plaster, PVC, rubber, ceramic tiles, and aluminum are less common architrave materials.

Architraves are usually made from the same material as the moldings and finishes in the home, creating a sense of uniformity. Hardwood is more likely to be used in historic buildings, whereas softwood or MDF are more likely to be used in modern homes.

Importance of Architrave

Architraves can add an extra layer of beauty to a room. An architrave also serves a functional purpose. The seams and joints created by a door or window built into a wall cannot simply be painted over.

Covering up these imperfections is made easier with an architrave, which creates a clean, beautiful look around them.

Architrave in Modern Construction

It conceals the joint between walls or ceilings that surround doors, windows, or other openings. The purpose of them is to give the openings of a house a finished appearance.

To allow building materials to expand and contract when temperatures vary, a gap is commonly left between plasterboard and window or door frames. Despite their purpose, these gaps are perfectly covered without compromising their functionality.

Hardwoods, softwoods, MDF, and other timber styles can be used for architraves. The use of MDF architraves is recommended for buildings that are subject to extremes of temperature. Ceramic tiles, rubber, aluminum, and PVC are less common materials used for architraves.

Due to the fact that they do not support the frame of a window or door, they are not structurally necessary.

Architrave in Architecture

Buildings have an upper portion covered with an entablature, a horizontal structure like a lintel. Entablatures consist of three parts: the architrave on the bottom, the frieze in the middle, and the cornice on top.

A structure’s stability is ensured by architrave elements in an entablature. Entablature’s foundation is directly above the vertical columns.

Architrave Features

Architraves conceal the connection between a door and its casing, giving it a finished look. Between the opening and the wall, they allow for any shrinkage or movement that may occur. It enhances the design of a window by adding depth.

The size of the architrave is determined by the width, depth, and length of the pack. A door’s width specifies whether the architrave surrounding the door is thick, its depth specifies how far the architrave projects out of the wall, and its length specifies its perimeter.

An in-depth comparison of river sand versus M sand

Sand enhances the aesthetic appeal of a space by adding texture and visual appeal.

The most important qualities of sand are that it is often pure, readily available, and economically intelligent. Keeping play areas safe for children can be achieved by building children’s sandpits. As well as being very cheap, it is also very convenient.

Define Sand

In the construction industry, sand plays a very important role. From the foundation to the finishing works like plastering, sand is used everywhere in the construction process. As a result of sand, concrete, mortar, asphalt, and cement are able to provide strength, bulk, and stability.

Define M Sand

Basically, M Sand, also known as Manufacturer Sand, is crushed rock or granite used in cement and concrete since it’s a natural sand substitute. A wide range of physical and mineralogical differences distinguish M sand from natural river sand.

Define River Sand

Normally, the riverbeds or riverbanks contain R Sand, also known as River sand naturally. River sand is widely used in construction and is readily available in the market. In addition to the increased trust in infrastructure, river sand is being used more in the construction industry, and the demand for river sand continues to grow.

Applications of Sand

• Among the many uses of sand, we can find aquariums, fringing reefs, beaches, and artificial coral reefs.
• Watermelon, peaches, peanuts, and other fruits and vegetables grow well in sandy soil.
• Moreover, mason jars can be filled with sand and tea lights to light up a passageway, which is another inexpensive way to brighten up a walkway.
• To prevent flare-ups around charcoal grills, we could use a small screw of sand.
• Using a little sand with warm soapy water, you can clean a narrow neck by mixing it with the water and putting it in the container. The use of sand can stabilize items that need proper repairing. By burying the broken pieces underneath sand grains, you can keep the elements together while gluing them.
• During icy or snowy conditions, the uses of sand helps improve the resistance, which in turn helps improve traffic safety.

Wrapping it Up

By mixing two cups of paint with a cup of sand, we can make a sand mix that will hold your painting or wall art in place. The sand that is used to make sandpaper is polished into paper by polishing it.

The frameworks used in the casting process can be constructed by mixing sand with clay dams to hoist the metal. Industrial sand or M Sand can make glass, such as foundry sand and abrasive sand.
