6 Main Types of Work Carried Out in Large-Scale Renovations! A Summary of the Specific Process!

Buildings such as condominiums, apartments, and factories gradually deteriorate over time.

If symptoms of deterioration, such as cracks in the exterior walls or a decline in waterproof performance, are left unattended,
there is a risk of shortening the overall lifespan of the building.

This is where large-scale repairs become important.

However, many people feel anxious because they do not know what specific work will be done or how the process will proceed.

What are large-scale repairs?

As explained at the beginning, buildings such as condominiums and apartments gradually deteriorate over the years in terms of exterior walls, waterproof layers, and equipment.

If these issues are left unattended, it could lead to a decrease in asset value and safety concerns.

To avoid such situations, large-scale repairs are carried out.

Here, we will first organize the basic definition and purpose of large-scale repairs, and then explain in detail the reasons why they are necessary.

Definition and Purpose

Large-scale repairs refer to
planned repair work conducted at regular intervals targeting the entire building.

This mainly includes repairs and painting of exterior walls, waterproofing work, and renovations of common areas.

Unlike partial repairs, a significant feature is the comprehensive restoration of the building’s functions and performance.

Additionally, by enhancing the aesthetics, it plays a role in improving the satisfaction of the living environment and protecting asset value in the medium to long term.

By implementing these repairs systematically, we can also prevent unexpected high-cost repairs, so it is essential to carry them out at the right time.

Necessity

The necessity for large-scale repairs arises from the unavoidable reality of building deterioration.

If cracks in the exterior walls or deterioration of the waterproof layer are left unattended, there is a high possibility of internal corrosion or water leakage due to rainwater intrusion.

Furthermore, rust on iron parts and equipment malfunctions directly lead to decreased safety.

To prevent such problems, timely large-scale repairs are essential.

Additionally, regularly conducting large-scale repairs increases the sense of security for residents, contributing to vacancy measures and promoting long-term occupancy.

For these reasons, large-scale repairs can be considered an important measure that contributes to the stabilization of building management.

Main Construction Contents of Large-Scale Repairs: 6 Selections

In large-scale repairs, multiple construction works are combined to restore the overall performance and safety of the building.

The construction contents vary depending on the condition of the building, but there are also many works that are commonly performed at regular intervals.

Here, we will explain the representative construction contents that are particularly important in large-scale repairs, considering their roles and purposes.

Temporary Construction

Temporary construction serves as the foundation for safely and smoothly carrying out large-scale repairs.

Typical tasks include the installation of scaffolding and the setup of protective sheets, aimed at ensuring the safety of workers and considering the surrounding environment.

Scaffolding is used in many processes such as exterior wall repairs, painting, and waterproofing, and since its strength and installation method affect the final outcome, it is considered a very important construction task.

Protective measures play a role in reducing paint splatter and noise, and by implementing them properly, it helps alleviate the burden on residents and nearby neighbors.

Exterior Wall Repair and Exterior Painting Work

Exterior wall repair and exterior painting work are essential tasks for maintaining the aesthetics and durability of a building.

If cracks or missing parts are left unrepaired, rainwater can infiltrate, potentially leading to the deterioration of concrete and corrosion of rebar.

The painting done after repairs not only enhances appearance but also plays a role in improving waterproofing and weather resistance.

By performing appropriate surface preparation and selecting the right paint, you can extend the lifespan of the exterior walls and help reduce future repair costs, so it is advisable to do this regularly.

Waterproofing Work

Waterproofing work is primarily conducted in areas exposed to rainwater, such as roofs, balconies, and shared corridors.

When the waterproof layer deteriorates, there is a high risk of serious damage to living spaces and structural elements due to leaks.

There are several types of waterproofing methods, including urethane waterproofing and sheet waterproofing, and it is important to choose based on the building’s structure and usage conditions.

By regularly performing waterproofing work, you can reduce the risk of leaks and maintain the overall durability of the building more easily.

Sealing Work

Sealing work refers to the process of filling gaps around joints in exterior wall materials and around sashes.

Sealing materials are prone to hardening and cracking due to aging, which can lead to a decrease in waterproof performance.

If left in a deteriorated state, it can become a pathway for rainwater intrusion, causing internal corrosion, so caution is necessary.

In large-scale repairs, it is common to remove existing sealing materials and replace them with new ones.

Sealing work is relatively detailed but plays an important role in ensuring waterproofing.

Painting of Iron Parts and Repair of Metal Components

Painting of metal parts and repairs are primarily conducted on common facilities such as stairs, handrails, and doors.

Metal parts are prone to rust, and if left unattended, they can lead to a decrease in strength and safety issues.

By removing rust through scraping and then applying paint, it becomes easier to halt the progression of corrosion.

Additionally, repairing any distortions or damages to metal parts can help prevent accidents during use.

Repairs and beautification work for common areas

Repairs and beautification work for common areas are aimed at enhancing the comfort of spaces used daily by residents.

This includes repairs to floors and walls in entrances, hallways, and stairs, as well as the replacement and cleaning of lighting fixtures.

Although these are not structural works, they are crucial as they significantly influence the overall impression of the building.

By improving aesthetics, resident satisfaction increases, which can also be effective in addressing vacancy issues.

In large-scale repairs, enhancing the quality of the living environment is just as important as functionality, so please consider this.

Large-scale repair contents by type of building

The contents of large-scale repair work vary significantly depending on the building’s purpose and the characteristics of its users.

Since the required performance and priorities change based on whether the building is residential or commercial, a uniform approach to repair work may not yield sufficient results.

Here, we will explain in detail the characteristics of large-scale repairs for condominiums, apartments, factories, and warehouses, as well as the points that are emphasized.

Large-scale repairs for condominiums

In large-scale repairs for condominiums, maintaining the safety and comfort of residents is prioritized.

Specifically, repairs to exterior walls and waterproofing, along with renovations of shared spaces such as corridors, stairs, and entrances, are the focus.

Moreover, since many residents live there for extended periods, considerations for noise and odors during construction, as well as thorough pre-construction explanations, are also important.

Furthermore, the enhancement of aesthetics and the strengthening of durability for the future are significant features of large-scale repairs in condominiums.

Large-scale repairs for apartments

In large-scale repairs for apartments, the balance of costs and maintaining occupancy rates are key themes.

Compared to condominiums, the smaller scale often limits the scope of work, but essential repairs such as exterior walls and roofs cannot be overlooked.

Especially, the impression of the exterior is directly linked to attracting tenants, so painting and beautification work for common areas tend to be emphasized.

By eliminating unnecessary work while accurately performing necessary repairs, it becomes easier to extend the building’s lifespan while maintaining profitability.

Large-scale repairs for factories and warehouses

In factories and warehouses, functionality and safety take precedence over livability, which is a characteristic of large-scale repairs in these settings.

Repairs to exterior walls and roofs, waterproofing work, as well as measures against leaks, floor reinforcement, and repairs to shutters and large doors are the main types of work.

Additionally, there are many cases where it is necessary to proceed with construction without stopping operations, requiring precision in project management and construction management.

By conducting repairs according to their purpose, we can prevent a decline in work efficiency and accident risks, leading to stable business operations.

What is the process for large-scale repairs?

For large-scale repairs, it is important to accurately understand the condition of the building and proceed in a planned manner.

If construction is advanced based on impulsive or ad-hoc judgments, it may lead to unnecessary cost increases, extended construction periods, and tenant troubles.

To avoid such situations and to proceed with large-scale repairs in a planned manner, it is essential to understand how the process from preliminary investigation to construction commencement will unfold.

Here, we will explain the stages of how large-scale repairs, primarily focused on condominiums and apartments, progress.

On-site Investigation and Deterioration Diagnosis

The first step in large-scale repairs is the on-site investigation and deterioration diagnosis of the entire building.

Specialized contractors will check for cracks and bulges in the exterior walls, peeling tiles, the condition of the waterproof layer on rooftop balconies, and rust on metal parts.

In addition to visual inspections, it is relatively common to conduct tapping surveys and tests using specialized equipment.

The results of the investigation are compiled into a report, clarifying the areas that require repairs and their urgency.

The accuracy of this diagnosis will influence the appropriateness of the subsequent construction content and costs, so it should be conducted carefully.

Repair Plan and Determination of Construction Content

Based on the results of the deterioration diagnosis, a repair plan is formulated.

In doing so, rather than fixing everything at once, we organize the construction items while considering the degree of deterioration, safety, and budget situation.

It is also an important point to select durable materials and methods with an eye on future repair cycles.

By clarifying the scope of work and priorities at this stage, it becomes easier to minimize changes in specifications and additional costs during construction.

Obtaining Estimates and Selecting a Construction Company

Once the repair plan is solidified, obtain estimates from multiple construction companies.

At this time, it is important not to judge solely based on the lowest price, but to consider the content of the work and aftercare.

Carefully review the estimates from each company and cautiously search for a reliable company that fits your objectives and budget.

If you have any unclear points or concerns regarding the estimate, we recommend confirming them before signing the contract.

Construction Explanation and Neighbor/Resident Communication

It is common practice to provide an explanation of the construction to residents and neighboring residents before starting work.

By informing them in advance about the construction period, working hours, and the presence of noise, vibration, or odors, you can help alleviate their concerns and dissatisfaction.

Especially in buildings with residents, it is essential to minimize the impact on their daily lives.

Conducting explanatory meetings, greeting rounds, and sharing information through posted notices can facilitate understanding of the construction and help prevent troubles.

Commencement of Work

Once all preparations are complete, we will start with the installation of scaffolding.

During the construction, make sure to regularly check the progress and confirm that it is proceeding as planned.

By proceeding under an appropriate management system, we can maintain quality while aiming for timely completion.

Reasons Why Large-Scale Repairs Vary by Building

When we hear “large-scale repairs,” we tend to imagine similar work being done on all buildings, but in reality, the content of the work varies significantly from building to building.

Let’s take a closer look at the reasons for this.

Differences in Age and Deterioration Status

The age of the building and its deterioration status are the most fundamental factors that influence the content of large-scale repairs.

For a building around 10 years old, the focus will likely be on minor crack repairs to the exterior walls and repainting.

On the other hand, for buildings over 30 years old, it may be necessary to carry out substrate repairs or complete renovations of the waterproofing layer.

Additionally, even for buildings of the same age, the rate of deterioration can vary depending on whether regular maintenance has been performed, which can ultimately change the scope of the work required.

Differences in Location and Usage Conditions

The content and rate of deterioration can also change based on the location and usage conditions.

For example, in coastal areas, salt damage can accelerate rust on metal parts, while buildings along busy roads may experience faster dirt and deterioration of exterior walls due to exhaust fumes.

Moreover, the areas that need focused repairs will differ between residential apartments and factories or warehouses due to differences in usage frequency and load conditions.

As such, large-scale repairs will vary based on the environment and purpose, so it is important to confirm these details in advance.

Changes in Required Work Due to Past Repair History

The content of the work can vary significantly based on what repairs have been carried out in the past.

If durable materials were used in the previous repairs, it may be possible to limit the scope of re-repairs.

Conversely, buildings that have only received partial emergency repairs may often require more extensive repairs or renovations.

Accurately understanding the repair history and avoiding duplicate work or unnecessary construction will contribute to balancing cost and quality, so it is advisable to first check what maintenance has been performed so far.
