ABSTRACT:

This article provides a comprehensive review of current research on volumetric-

modular rapidly deployable housing technology, mainly referencing publications from

ResearchGate. With rising demands for efficiency, speed, and sustainability, volumetric-modular

construction (VMC) presents notable advantages compared to conventional methods. Key

benefits include a construction time reduction of up to 50%, an economic efficiency

improvement of 20%, and better quality due to as much as 80% of work being conducted in

controlled factory settings. Innovations such as Building Information Modeling (BIM) and

Artificial Intelligence (AI) are transforming design and logistics, alongside advanced materials

like Cross-Laminated Timber (CLT) and aerogels. However, despite its significant potential,

VMC encounters systemic challenges, particularly substantial gaps in regulatory frameworks

(especially concerning high-rise buildings), major transportation constraints related to module

dimensions and weight, and a lack of qualified workforce. Research also suggests that the

thermal properties of materials like mineral wool may deteriorate under climatic conditions,

affecting long-term energy efficiency. The study concludes that while VMC stands as a highly

promising and adaptable option for various scenarios, its broader implementation relies on

overcoming these regulatory, logistical, and human resource challenges through coordinated

efforts across the industry and ongoing scientific inquiry.

1. Introduction

The contemporary construction industry faces increasing demands for efficiency, project speed,

economic viability, quality, and sustainable development. In this context, rapidly deployable

building technologies, particularly volumetric-modular construction, are gaining significant

relevance.

1

. Global challenges, such as rapid urbanization and the need for swift housing

provision in emergency situations, as well as construction in remote or extreme climatic

conditions, underscore the strategic importance of modular solutions.

Growing global demands, driven by rapid urban population growth and the imperative for swift

responses to crises, not only stimulate but effectively dictate a shift towards industrialized and

rapidly deployable construction methods. Traditional approaches, characterized by lengthy

timelines and high resource intensity

2

, prove inadequate to meet current requirements.

Consequently, volumetric-modular homes are transforming from an alternative option into a

strategic necessity for ensuring the sustainable development of the construction sector. This shift

is driven not only by a pursuit of increased efficiency, but also by a fundamental adaptation to

changing conditions and the need to address basic societal needs.

Modular construction has deep historical roots and has continuously adapted to evolving societal

needs. A significant impetus to its development was provided during periods that required the

rapid and efficient erection of numerous buildings, such as during World War II.

1

In recent

decades, advancements in construction technologies have focused on enhancing energy

efficiency and achieving sustainable development, leading to a renewed interest in modular

systems.

4

The objective of this article is to systematize and analyze contemporary research in the field of

volumetric-modular rapidly deployable housing technology, based on publications available on

the ResearchGate platform. To achieve this goal, the following tasks were set: to clarify the

terminology and classification of volumetric-modular construction systems, identify key

advantages, review innovative technologies and materials, analyze structural features and

operational characteristics, and identify the main challenges and prospects for the further

development of this technology.

2. Literature Review and Methodology

2.1. Definition and Classification of Volumetric-Modular Rapidly Deployable Buildings

Buildings constructed using volumetric block modules (VBMs) represent a type of rapidly

deployable building system (RDBS).

4

These systems are distinguished by minimal construction

times, a high degree of factory readiness, technological efficiency of on-site work, and relatively

low cost.

3

However, existing literature exhibits some terminological ambiguity. Rapidly

deployable buildings are sometimes erroneously equated with volumetric modular buildings,

metal-framed buildings, or structures erected using permanent formwork.

4

Researchers identify several common types of RDBS, including frameless, framed (specifically,

frame-monolithic), volumetric-block (modular or modular-block), core, and shell (frame-tent or

frame-membrane) systems.

4

The main structural schemes for VBM buildings include

homogeneous block, block-panel, heterogeneous block, block-panel with staggered block

arrangement, frame-block, as well as schemes utilizing suspended or non-load-bearing (hanging)

blocks, and block-spiral systems supported by a rigid core.

4

VBM frames can be made from various materials, which determine their strength and operational

characteristics. The most common types are steel frames, including light-gauge steel (LGS) and

light metal structures (LMS). Wooden frames, including hollow box timber elements and cross-

laminated timber (CLT), as well as reinforced concrete structures, are also employed, often

forming a cap or cup.

4

The existing terminological ambiguity and the absence of a comprehensive, universally accepted

classification of volumetric-modular systems

4

pose a significant barrier to standardization,

regulatory development, and consequently, to the widespread adoption and investment in this

technology. Clear terminology and classification are fundamental for developing relevant

building codes and standards. Without this foundation, each VBM project may require individual

justification and approval, increasing costs, timelines, and risks, thereby deterring investors and

slowing down mass implementation. Thus, the issue of terminology directly impacts the

economic and regulatory viability of the technology.

The urgent need for a unified classification of VBM building systems is emphasized. Such a

classification should consider multiple criteria, including the nature of the action, functional

purpose, class, mobility, number of stories, structural scheme, VBM dimensions, materials used,

https://ijmri.de/index.php/jmsi

341

changes in overall dimensions during transportation and installation (distinguishing between

transformable and non-transformable VBMs), as well as durability and fire resistance indicators.

2.2. Advantages of Volumetric-Modular Construction

Volumetric-modular construction offers a range of significant advantages that make it an

attractive alternative to traditional methods.

Economic Efficiency, Shorter Timelines, and Enhanced Productivity. The factory-based

production of modules is considerably quicker than traditional methods due to a controlled

manufacturing setting, opportunities for process automation, and repetitive tasks. This approach

enables simultaneous module production alongside foundation work at the construction site,

contrasting with the sequential nature of traditional construction. Studies show that this

technology can cut construction time by as much as 50% and improve economic efficiency by

20%. For instance, in the case of a two-story residential building, prefabrication can reduce the

project timeline by 63 days compared to conventional approaches. Cost savings are realized by

significantly lowering the requirements for formwork (up to 75%), scaffolding (75-90%), and

wet concrete (90%). Additionally, lower costs stem from the high readiness level of modules at

the factory, incorporating both exterior and interior finishes, which reduces the need for on-site

labor. As much as 80% of all tasks can be shifted to the manufacturing location, facilitating the

employment of more skilled workers and decreasing labor expenses.

Quality Control, Waste Reduction, and Environmental Friendliness.

Factory conditions

ensure significantly better quality control throughout all stages of production, resulting in a

substantial reduction in defects compared to traditional construction methods.

1

Since most work

is performed in the factory, the volume of construction waste directly on-site is considerably

reduced, lowering disposal needs and associated costs.

1

Modular construction also contributes to

a reduction in negative environmental impact, including fewer transportation cycles, which leads

to a decrease in accidents and noise levels.

2

Energy Efficiency and Sustainable Development.

The use of energy-efficient materials in

modular designs contributes to reduced electricity consumption during the operational phase of

buildings.

6

Modular construction is considered a crucial factor promoting the sustainable

development of the construction industry as a whole.

3

The complex of advantages offered by volumetric-modular construction—speed, cost-

effectiveness, quality, and environmental friendliness—is not merely a sum of individual

benefits but forms a synergistic effect that transforms the entire paradigm of construction

production (Fig.1). Relocating the majority of work to controlled factory environments not only

reduces time and costs but also enables the implementation of stricter quality control, the use of

resource-saving technologies, and waste minimization. This cumulative effect leads to significant

improvements in energy efficiency and a reduction in negative environmental impact. Such a

comprehensive approach, rather than just isolated benefits, positions volumetric-modular homes

as a key tool for achieving sustainable development goals in the construction sector.

Methods

2.3. Research Methodology

This study constitutes a systematic review and analysis of scientific publications available on the

ResearchGate platform. Relevant sources were identified using keywords encompassing aspects

such as "volumetric-modular construction," "rapidly deployable buildings," "prefabrication,"

"innovative technologies," and "application in various conditions."

In selecting publications, priority was given to highly cited sources, ensuring the relevance and

scientific significance of the included data.

9

Articles containing experimental data, numerical

simulation results, literature reviews, and analyses of specific case studies of volumetric-modular

technologies were also considered. Particular attention was paid to identifying structural features,

technological solutions, operational characteristics, as well as existing problems and prospects

for the further development of this construction methodology. This approach enabled the

formation of a comprehensive understanding of the current state of research in the field of

volumetric-modular, rapidly deployable homes.

3. Research Results

3.1. Innovative Technologies and Materials

The Role of BIM Technologies and Artificial Intelligence in Design and Optimization.

The

integration of digital technologies, such as Building Information Modeling (BIM) and Artificial

Intelligence (AI), is fundamentally transforming the approach to designing, constructing, and

operating modular buildings. BIM technologies ensure high efficiency and process

synchronization by creating detailed 3D models that facilitate visualization, early detection of

potential issues, and improved project understanding among all stakeholders.

1

In the context of

modular construction, BIM enables precise planning of module production and subsequent on-

site assembly, significantly reducing errors and minimizing material waste.

1

This technology also

fosters close interaction between the design, module manufacturing, and installation phases, as

any project changes are instantly reflected in the shared model accessible to all interested

parties.

1

Furthermore, BIM allows for virtual simulations and comprehensive analyses, including

energy efficiency assessment, load calculations, and checks for compliance with safety standards

and structural stability, thereby optimizing building performance even before physical

https://ijmri.de/index.php/jmsi

343

construction begins

1

Artificial intelligence complements BIM capabilities by optimizing the design process for

modules. It analyzes vast amounts of data from previous projects, proposing optimal solutions

for module geometry, placement, load-bearing capacity, and energy efficiency, which

substantially reduces design time and costs.

1

AI also finds application in planning and logistics,

analyzing variables such as production capacity, resource availability, and delivery/assembly

conditions to develop the most efficient work plans.

1

In the module production process, AI

systems enhance quality control, overall efficiency, and shorten production cycles, directly

impacting the reduction of the final product cost. AI can also optimize production processes and

contribute to the implementation of lean construction principles by analyzing employee

movements.

1

On the construction site, AI, integrated with drones and autonomous robots,

improves the accuracy of module installation and reduces risks for workers.

1

Application of New Construction Materials.

The development of volumetric-modular

construction is closely linked to the introduction of innovative materials that improve operational

characteristics and expand architectural possibilities.



Cross-Laminated Timber (CLT)

: This material, composed of layers of timber glued

perpendicularly to each other, possesses high strength, making it an ideal choice for use as load-

bearing elements in walls, floors, and roofs of modular buildings. Its excellent thermal insulation

properties and relatively low weight simplify transportation and contribute to reduced energy

consumption for heating and cooling buildings.

1



Aerogels

: These are ultra-light materials with outstanding thermal insulation properties.

They serve as a highly effective insulation layer in modular structures, significantly reducing

heat loss without requiring an increase in wall thickness.

1

In combination with nanomaterial-

based thermal insulation, aerogels contribute to reducing the building's overall energy

consumption and carbon emissions.

1



Composite Materials

: Increasingly applied in modular design, as they allow for

combining the best qualities of metal, plastic, and wood. These materials are lightweight, strong,

resistant to corrosion, rot, moisture, and other aggressive environmental factors, ensuring the

creation of durable, reliable, and aesthetically appealing modular elements.

1



Recycled Materials

: Modular construction technology actively supports the use of

building materials produced in accordance with principles of ecological compatibility and

sustainability. Materials from recycled raw materials, such as recycled plastic and rubber, not

only reduce waste but also enhance the overall environmental value of modular construction,

finding application as insulation boards, flooring, and other building elements.

1

The synergy between digital technologies (BIM, AI) and innovative materials (CLT, aerogels,

composites) is a key factor in overcoming traditional limitations of modular construction, such as

architectural monotony and optimization complexities. Digital tools enable the most efficient use

of new materials' potential, for example, optimizing module geometry for CLT use or precisely

calculating layers with aerogels. Artificial intelligence can generate unique architectural

solutions, overcoming the problem of "architectural monotony"

6

, while utilizing the properties

of composites to create complex forms. This leads to the creation of more complex, functional,

and sustainable structures that would be impossible or inefficient to achieve using traditional

methods and materials (Fig. 2).

3.2. Structural Features and Nodal Connections

Types of Volumetric Block-Module Frames.

As noted, VBM frames can be made of steel,

timber, or reinforced concrete. The choice of frame material depends on specific requirements

for strength, weight, thermal performance, and building operating conditions.

4

Each material

type offers unique advantages, allowing modular designs to be adapted to a wide range of

applications.

Overview and Analysis of Common Horizontal and Vertical Nodal Connections.

The quality

and type of nodal connections mainly used determine the efficiency and reliability of modular

construction. The most common connection for horizontal and vertical joints in 3D modular

blocks is the "tongue and groove" type.

12

This type of connection ensures high assembly

precision and structural strength.

In addition to "tongue and groove," other types of connections are also employed:



Threaded connections:

These involve the use of bolts, studs, and nuts for module

fixation. For example, horizontal module connections can be achieved with reinforced bolts and

reinforced lock nuts.

12

Reinforced eye bolts are also frequently used.

12

Metal plates are installed

at the joints, and typical details of these plates for fastening modular blocks include floor, ceiling,

bolt fastening, tie, and support plate elements.

12



Internal and external tie bolts:

When assembling single-level VBM systems, modules

are connected using internal and external tie bolts. This is characteristic of VBMs made from

shipping containers, where bolts are installed in container fittings, and internal bolts are

tightened with clamps.

12



Twistlock fasteners:

Used for connecting container-type volumetric blocks and installed

in standard shipping fittings.

12



Special corner cones:

Applied for connecting two or more levels of modular systems,

preventing module displacement

12



Special tension ties:

Along the facade perimeter of multi-level buildings, lower and

upper volumetric blocks are connected using special tension ties.

12

Innovations in Nodal Connections.

Technological advancements have led to the emergence of

innovative connection systems, such as the Modular Integrating System (MIS) and the

VectorBloc multi-functional fastening. These systems, also based on the "tongue and groove"

principle, provide both horizontal and vertical structural connections.

12

MIS enables the

fabrication of finished modules with fastening elements, both in the factory and on the

construction site. To create a unified structure, connecting strips with tenons and grooves are

installed along the entire perimeter of the upper and lower parts of the module. One strip from

each module in each direction connects with the strips of adjacent modules.

12

https://ijmri.de/index.php/jmsi

volume 4, issue 5, 2025

345

In MIS, tenons are located on the upper corner fastenings of the modules, and grooves are on the

lower ones. Horizontal connection of VBMs is achieved by placing connecting plates (strips)

over the tenons and securing them with bolts. For vertical connection of VBMs, upper-tier

modules are positioned so that the tenons of the lower-tier VBMs align with the grooves of the

upper-tier VBMs, ensuring centering of the two tiers. The VBMs are then tightened with bolts,

forming an angular connection of four blocks across two tiers. This fastening method allows

modules to be stacked and joined to create fully reinforced buildings of almost any shape.

12

Scientific publications also propose a horizontal connection of metal frames in volumetric

modular blocks using "tongue and groove" technology, featuring sigma-shaped protrusions

(tenons) and grooves. These connecting parts are installed along the perimeter of the combining

blocks, with some having protrusions and others grooves.

12

Vertical connection in MIS is

achieved using locking clamps and L-shaped elements that have sigma-shaped protrusions

(tenons) and grooves in both vertical and horizontal directions. These are installed along the

perimeter of the upper parts of the first-tier VBMs and the lower parts of the last-tier VBMs, and

on middle tiers, they are on both the lower and upper parts of the building's VBMs

12

Ensuring Strength, Rigidity, and Installation Manufacturability.

The efficiency of modular

construction largely depends on the nodal connections used.

12

Volumetric block modules are

inherently strong structures, but their combined performance as part of a unified building system

requires rigid horizontal connections to ensure reliable and long-term operation.

12

This implies

that all VBMs must be securely connected both horizontally and vertically. The necessary degree

of strength and rigidity of plywood load-bearing elements with "tongue and groove" connections

has been confirmed by transverse bending tests.

13

The development and optimization of nodal connections, from simple bolted joints to innovative

systems like MIS, are critical factors determining not only the structural integrity and durability

of volumetric-modular buildings but also their manufacturability during installation and the

speed of erection on-site. This directly impacts the economic attractiveness and competitiveness

of modular construction. Advanced nodal connections significantly reduce installation time and

labor, enhance assembly precision, and ensure the necessary strength and rigidity of the entire

structure. Without reliable and technologically efficient connections, the advantages of factory

fabrication could be negated by the complexity and inefficiency of on-site assembly (Tab.1).

3.3. Operational Characteristics and Testing

Thermal Properties of Enclosing Structures and the Influence of Climatic Factors.

The

energy efficiency of a building is largely determined by the thermal characteristics of its

enclosing structures, particularly wall panels.

14

These characteristics directly influence the indoor

microclimate, heating and cooling costs, and overall comfort of living and working in the

building.

14

Experimental studies have shown that climatic factors can influence the thermal properties of

materials used in modular building wall panels. For example, for mineral wool wall panels, an

increase in thermal conductivity from 0.037 W/m·K to 0.04 W/m·K (an 8% increase) and a

decrease in thermal resistance by 3% (from 2.76 to 2.67 m²·K/W) were recorded after exposure

to climatic factors.

14

These changes are typically associated with moisture absorption by the

material and its structural degradation. The deterioration of thermal insulation properties leads to

increased heating costs and reduced building energy efficiency over its lifespan, especially in

regions with harsh climates.

14

Research on Seismic Resistance and Durability of Volumetric-Modular Structures.

VBM

construction systems demonstrate high resistance to static, dynamic, cyclic, and seismic loads.

6

This makes them a promising solution for construction in seismically active regions. However, to

ensure safety and reliability, further development of the regulatory framework is necessary.

Specifically, national standards for testing modules for seismic effects are required, especially

for reinforced concrete modules.

15

The durability of VBM buildings directly depends on the

correct selection of materials and, equally importantly, on the reliability and quality of nodal

connections.

7

Application of Experimental and Numerical Modeling Methods.

Both numerical and

https://ijmri.de/index.php/jmsi

volume 4, issue 5, 2025

347

experimental methods are actively used for the comprehensive evaluation and optimization of

volumetric-modular structures. Numerical and computer modeling, including information

modeling and computational materials science, are applied to analyze the stress-strain state,

dynamics, and stability of building structures at various stages of their life cycle.

These methods

enable the prediction of

the behavior of structures under various loads and impacts.

Experimental studies play a key role in confirming theoretical propositions and modeling results.

For instance, experimental studies have been conducted to confirm theoretical provisions

regarding the strength, crack resistance, and deformability of reinforced concrete elements

reinforced with composite materials.

16

Digital technologies are also actively used in field studies,

such as laser scanning for precise surveying of existing buildings and monitoring of load-bearing

structures using geodetic measurements and seismometric methods.

11

The seismometric method

enables a comprehensive inspection of a building and the detection of significant changes in

load-bearing structures without requiring direct instrumental intervention or visual inspection of

each component. It achieves this by determining natural frequencies and vibration modes, which

can indicate localized damage.

11

Despite the generally high resistance of volumetric-modular structures to extreme loads, such as

seismic impacts, their long-term operational efficiency, particularly concerning thermal

performance, remains vulnerable to climatic factors.

14

This indicates the necessity not only for

further research in materials and connections but also for developing comprehensive design

approaches that account for the dynamic change in material properties over the life cycle to

ensure stated energy efficiency and durability. There is a dissonance between the high structural

reliability of VBMs in extreme conditions and their potential vulnerability to ordinary climatic

influences, affecting their operational characteristics. This means that to ensure true VBM

durability and sustainability, strength alone is insufficient; a deep understanding and

compensation for changes in material properties, especially insulation, throughout the building's

life cycle are required. This necessitates a more integrated approach to materials science and

design, as well as the development of new standards for assessing long-term operational

performance.

3.4. Application Specifics in Various Conditions

Specifics of Construction in Far North Conditions.

The application of volumetric-modular

technologies in the Far North demonstrates significant economic and environmental advantages.

6

VBMs exhibit high resistance to static, dynamic, cyclic, and seismic loads, as well as high

installation manufacturability, which is critically important in conditions of a limited

construction season.

6

However, construction in these regions presents unique challenges, including extremely low

temperatures, high humidity, strong wind loads, and the presence of permafrost.

6

There are also

serious transportation limitations related to the large dimensions and weight of VBMs.

According to Russian road traffic regulations, oversized cargo should not exceed 12 m in length,

2.55 m in width, and 4 m in height from the road surface.

8

Meanwhile, Chinese researchers note

that VBMs can reach 5.7 m in width and 12 m in length, and modules easily transportable

without significant difficulty typically have a width of less than 4.5 m and a length of up to 13

m.

6

Vibrations during transportation can lead to a reduction in the stated strength of some VBM

components, with the degree of damage depending on the road category.

6

To overcome these difficulties, the following solutions are proposed: the use of lightweight

VBMs, equipping vehicles with vibration dampeners (though this increases cost), and

considering specific principles of construction on permafrost. The latter includes either

https://ijmri.de/index.php/jmsi

volume 4, issue 5, 2025

348

preserving frozen ground throughout the building's lifespan (e.g., using ventilated crawl spaces)

or, conversely, thawing it with the use of pile foundations or concrete column foundations.

6

Architectural requirements for Arctic construction also have their specific features: it is

important to consider local experience, prioritize rounded forms that are less susceptible to wind

and seismic loads, and use compact buildings with a closed contour and minimal open spaces.

Smooth exterior surfaces help reduce snow accumulation. Buildings should have double

vestibules at entrances and a minimal number of entry/exit points, while adhering to evacuation

requirements. For facades, bright colors are recommended, considering the local landscape

6

Development of High-Rise Modular Construction.

Modern construction technologies allow

for the erection of not only low-rise but also multi-story, high-rise, and even unique, rapidly

deployable buildings. An example is a 57-story skyscraper built in 19 days using prefabricated

modules with a high degree of factory readiness.

3

However, the development of high-rise modular construction faces several significant limitations.

One of the main barriers is the lack of an adequate regulatory framework. The existing GOST R

58760–2019 standard, which regulates modular block containers, does not apply to buildings

taller than three stories, forcing companies to prove the load-bearing capacity of the module's

frame for each specific case that falls outside the standard.

1

This leads to increased time and

costs for design and approval. Furthermore, there is a lack of experience and knowledge among

specialists, as well as a shortage of skilled labor in modular construction, which hinders the full

realization of the technology's potential.

10

Additional transportation costs, which can reach 18%

of the total project cost, and difficulties in ensuring the required fire resistance are also

significant obstacles.

10

Application of Modular Structures for Temporary Housing.

Modular structures play a

crucial role in providing temporary housing, particularly in emergency situations and following

natural disasters.

5

In this context, two main types of temporary housing are distinguished:



Prefabricated components:

Easily transportable and can be erected by local residents or

volunteers.

5



Ready-made structures (prefabricated structures):

Can be immediately integrated in

emergency situations, but their transportation is more complex.

5

The application of volumetric-modular technologies in extreme conditions (e.g., the Far North)

and for high-rise construction demonstrates that, while the technology possesses high

adaptability, its successful implementation critically depends on overcoming logistical

(transportation) and regulatory barriers, as well as on developing specialized design and material

science solutions for unique conditions. This underscores that "rapid deployability" is not a

universal property, but rather requires a deep adaptation to the context. The potential of VBMs in

complex conditions cannot be realized without addressing external infrastructural and legal

issues. In such cases, "Rapid deployability" becomes not just a matter of technology but also a

matter of systemic readiness, encompassing transport infrastructure, regulatory frameworks, and

the availability of qualified personnel. Thus, the success of VBMs in specific conditions depends

not only on internal technological improvements but also on external factors requiring a

comprehensive approach.

4. Discussion

Comprehensive Analysis of the Realization of Volumetric-Modular Construction

https://ijmri.de/index.php/jmsi

349

Advantages

Volumetric-modular construction, as demonstrated in the results section, offers significant

advantages over traditional methods, including reduced timelines (up to 50%

1

), lower costs (up

to 20%

2

), enhanced quality through factory control

1

, minimized waste

2

, and improved

environmental performance.

6

These benefits are not isolated but interconnected, forming a

holistic system for efficient and sustainable construction. The high degree of factory readiness

3

allows for the transfer of up to 80% of labor-intensive work to a controlled environment

1

,

leading to increased productivity and reduced dependence on weather conditions.

Despite the obvious and quantitatively confirmed advantages of volumetric-modular structures,

their full potential and widespread adoption are hindered not so much by the technological

limitations of the modules themselves, but by external systemic factors. These factors include an

outdated regulatory framework, logistical complexities, and a shortage of qualified personnel. If

the technology itself is efficient, but its implementation is difficult, this indicates that the

problem lies outside the technology itself. These are not merely "challenges," but systemic

"impediments" that prevent the industry from fully utilizing existing technological achievements.

This highlights the need to shift from localized technological innovations to a comprehensive

transformation of the entire construction ecosystem. Thus, the discussion should move from

questions about whether volumetric-modular construction can be effective to questions about

what prevents its widespread adoption, emphasizing the need for macro-level reforms.

Identification and Analysis of Key Challenges and Limitations

Regulatory and Standardization Gaps. A major obstacle to modular construction is the lack of

modern and comprehensive regulatory documents. The current GOST R 58760–2019, which

governs modular block containers, does not extend to buildings higher than three stories. This

limitation creates legal and engineering issues, requiring developers to individually demonstrate

the load-bearing capacity of each module. Consequently, the design and commissioning process

is significantly delayed. There is an urgent need for new standards, particularly for testing

loading and seismic effects in reinforced concrete modules.

Transportation and Logistics Complexities.

The large dimensions and significant weight of

volumetric block-modules

8

substantially limit the choice of transport vehicles and delivery

routes.

6

This leads to increased transportation costs, which can account for up to 18% of the total

project cost.

10

Furthermore, vibrations occurring during transportation can negatively affect the

stated strength of module components.

6

Shortage of Qualified Specialists and Experience.

The lack of sufficient experience and

knowledge, as well as a deficit of skilled labor, are serious obstacles throughout the entire life

cycle of modular construction.

10

This impacts the quality of design, production efficiency, and

installation accuracy, ultimately increasing project timelines and costs.

Architectural Monotony.

In public perception and among some specialists, there is a notion of

architectural uniformity and limited forms for buildings constructed from VBMs.

6

Although

modern technologies, such as BIM and AI, as well as new materials, allow for the creation of

customized and complex architectural solutions
