    CPM's journey of more than 20 years

    CPM's journey of more than 20 years of growth

    Ha Noi CPM Construction Corporation (CPM) was founded on 2 October 2004. After more than 20 years of growth, CPM has matured from a construction company into a specialist in consulting, designing, fabricating and installing aluminium & glass systems for many residential and industrial projects nationwide.

    Throughout this journey, CPM has continuously improved its expertise and invested in people, technology, its factory and management systems to better meet the technical, schedule, quality and aesthetic requirements of each project.

    For CPM, each project is not just a work item to finish on time but the result of research, calculation, coordination between many departments, tight control of every stage and the responsibility of the whole team.

    That is why, for more than two decades, CPM has taken REPUTATION – QUALITY – EFFICIENCY as its operating motto and the measure of the company's capability.

    CPM believes a sustainable brand is built not only on scale or the number of projects delivered, but on how a company keeps its commitments, creates real value and builds long-term trust with clients, partners and its own people.

    From a construction foundation to in-depth aluminium & glass expertise

    From its founding in 2004, CPM set its direction on professional expertise, construction quality and client trust.

    As the construction industry demands ever more of technology, precision and coordination, CPM has expanded its capability from traditional construction into architectural aluminium & glass – a field requiring close integration of design, engineering, materials, fabrication and installation.

    Through each stage of growth, CPM has accumulated hands-on experience from many types of projects, including high-rise apartments, commercial complexes,

    offices, hotels, public buildings, infrastructure and projects with special architectural and technical requirements.

    Working across many building groups has helped CPM steadily improve its ability to advise on and deliver aluminium & glass works in a more integrated way.

    Today, CPM can deliver many items within a single chain of work, from aluminium & glass technical consulting, façade system design, door and window design, and partition design and installation to selecting aluminium systems, glass and hardware. CPM also supplies materials, fabricates and manufactures in its factory, installs on site, controls quality, manages safety and provides warranty after project completion.

    CPM always recognises that every project has its own requirements. No two buildings are exactly alike in architecture, function, site conditions or investment goals. So CPM does not apply one fixed solution to every project.

    Instead, the engineering team studies the documents, design requirements, building scale and actual conditions to develop a better-suited approach.

    For projects with special requirements, CPM can assemble a specialist team to research and develop new aluminium dies, dedicated to the technical and architectural requirements of each building. This capability helps CPM widen its range of solutions and better serve highly complex projects.

    People – the foundation of CPM's capability

    CPM believes technology and machinery create productivity, but people are what ultimately determine the quality of a project.

    That is why, alongside investment in its factory and equipment, CPM always focuses on building a team with expertise, experience and a sense of responsibility.

    The CPM team includes managers, design engineers, technical consultants, economics and planning staff, factory personnel, technicians and installation crews. Each holds a different role but all take part in one unified delivery chain.

    Going from an initial drawing to a finished product on site involves many departments working together. Designers need to understand production requirements; the factory must follow technical specifications closely; installation teams must fully understand the solution and erection method; and management must control schedule, quality and resources.

    This connection between departments is the foundation that keeps CPM's project delivery consistent.

    Engineers and technical consultants

    CPM's engineers directly study the architectural documents, drawings, technical requirements and actual conditions of each project.

    From this information, they analyse and propose solutions for aluminium systems, glass, hardware, construction details and installation methods.

    On large projects, choosing a product system cannot be separated from the overall questions of design, durability, function, aesthetics and buildability. So CPM's engineering team looks at projects not only from a product perspective but also at the compatibility of many different factors.

    Experience gained across many projects helps the CPM team proactively identify key issues, resolve technical problems as they arise and adjust solutions when site conditions change.

    Production team

    At the CPM factory, engineers, technical staff and skilled workers turn design solutions into aluminium & glass components and products. This stage directly affects the accuracy, consistency and quality of the output.

    CPM combines the experience of its workers with modern machinery and production lines to reduce errors, increase productivity and improve control.

    Beyond skill, discipline and process compliance are also highly valued in CPM's production environment.

    Installation team – ensuring quality, schedule and safety

    Installing aluminium & glass, especially on high-rise buildings and façades, always demands precision, close coordination and a strong safety culture.

    CPM's installation teams are organised around the needs of each project and work with the engineering departments to resolve issues on site.

    CPM's goal is to maintain a balance of Engineering – Quality – Schedule – Safety. This is also the basis for the company to keep building a capable, professional installation team that takes responsibility for every project.

    A clear, professional management structure

    The organisational, management and executive structure of Ha Noi CPM Construction Corporation is established in accordance with Vietnamese law and the Company Charter.

    CPM's governance system includes the Board of Directors, the General Director, the Supervisory Board, Deputy General Directors and functional divisions and departments.

    At the head of the executive team is the Company's General Director. Advising and supporting the General Director are two Deputy General Directors in charge of the two main functional groups: the Economics – Planning Division and the Engineering Division.

    the Economics – Planning Division

    The Economics – Planning Division comprises the Finance – Accounting Department, the Economics – Planning & Tendering Department and the Administration – HR Department.

    This division handles finance, resources, delivery planning, tendering, administration and HR. It is the foundation that keeps the company running smoothly and prepares the right resources for each project.

    the Engineering Division

    The Engineering Division comprises the Design Department, the Production Factory and the Installation Department.

    This division directly carries out CPM's core activities, from researching solutions, design and product fabrication to on-site installation.

    A clear organisation by functional group helps CPM increase specialisation and enables departments to coordinate effectively throughout the project life cycle.

    The factory – a key foundation of CPM's capability

    One of the factors that gives CPM greater control over production and quality is its own factory.

    The CPM production factory belongs to Ha Noi CPM Construction Corporation and is located at Lot CN4, Phu Nghia Industrial Park, Chuong My District, Hanoi.

    The factory has a total area of over 1 ha, with average production capacity of around 15,000 m²/month. It is where fabrication, production, inspection and preparation of products take place before delivery to site.

    Investing in technology to raise production capacity

    The factory is equipped with advanced, modern and integrated production lines imported from suppliers in Germany, Italy and other markets strong in industrial equipment.

    Investing in machinery is not only about productivity. For CPM, technology also supports quality control and improves machining accuracy.

    By progressively automating management and production, CPM aims to reduce machining errors, increase product consistency, strengthen technical control, shorten production time and respond more proactively to project schedules.

    Alongside machinery, CPM still sees its people as a key factor. Training and upskilling of the factory team is therefore maintained in parallel with equipment investment.

    Quality control before dispatch

    Every product is inspected before leaving the factory against criteria set by CPM and the requirements of each project. Particular attention is paid to machining quality, accuracy, safety, compliance with the design, consistency and aesthetics.

    Inspecting products before they reach site helps prevent errors during installation and adds another layer of control to the whole delivery process.

    At the factory, CPM also has a showroom presenting solutions, product samples and material systems to clients and partners.

    Coordinated aluminium & glass solutions for every project

    In aluminium & glass, building quality does not depend on a single factor. A system can only perform well when the design, aluminium system, glass, hardware, construction details and installation method all work together.

    That is why CPM focuses on providing integrated solutions for aluminium & glass systems inside and outside the building, rather than simply selling or installing individual products.

    Depending on the nature and scale of the project, CPM studies solutions using many different material systems.

    Featured aluminium system brands include:

    • Schüco – Germany;
    • Technal – France;
    • Fletcher – Sweden;
    • Lixil – Japan;
    • Xingfa – China.

    Glass brands and suppliers include:

    • Saint-Gobain – France;
    • Viracon – USA;
    • Pilkington – United Kingdom;
    • AGC – Belgium;
    • Kibing – Malaysia;
    • CSG – China;
    • Xinyi – China.

    Hardware brands include:

    • Roto – Germany;
    • Häfele – Germany;
    • Giesse – Italy;
    • CMECH – USA;
    • NABCO – Japan;
    • Kinlong – China;
    • Draho – China;
    • Hiwin – China.

    This diversity of materials gives the CPM team a stronger basis for developing solutions tailored to each project's architectural, performance and delivery requirements.

    For special projects, CPM can also research and develop its own aluminium dies, increasing flexibility in consulting and delivering solutions.

    Quality controlled throughout the process

    For CPM, quality is not an inspection done once a building is complete but something controlled from the very first steps.

    The company applies an ISO 9001:2015 quality management system across its organisation. The management system runs throughout Concept design → Tendering/bidding → Contract preparation and review → Detailed design → Production → Installation → Completion → Warranty.

    Controlling the whole chain helps CPM proactively detect issues that could affect the result. Rather than only fixing errors once they occur, CPM aims to control them from the preparation stage.

    CPM's quality management system is also regularly reviewed and improved to better suit the nature of each project. Feedback from clients, partners and periodic inspections is used as real data to keep improving the way the company works.

    Throughout delivery, CPM always focuses on three criteria: Schedule – Quality – Occupational safety.

    Occupational safety – responsibility for every person

    CPM always holds that people are its most valuable asset. Occupational safety is therefore not just a procedural requirement but a key principle of the company's working culture.

    The safety management system is built on compliance with Vietnamese regulations on construction safety. Rules and measures are updated to reflect changes in technology, machinery, equipment, construction methods and actual site conditions.

    During project delivery, the CPM team focuses on identifying potential hazards, analysing risks and establishing appropriate preventive measures. Internal training is also maintained so that staff have the knowledge they need about the safety system.

    CPM understands that a project finished on schedule but without ensuring safety cannot be called a success. That is why safety is always one of the key measures CPM uses to evaluate delivery quality.

    The projects that shaped CPM's journey

    Over more than 20 years, CPM has contributed to many projects nationwide. Each project is a milestone in building experience, refining capability and establishing the company's reputation.

    Featured projects include:

    • Sunshine Crystal River;
    • Taseco Long Bien;
    • Crystal Holidays Van Don;
    • The Holiday Ha Long;
    • Vic Grand Square;
    • Terminal T2 – Noi Bai International Airport;
    • Yen So Bus Station;
    • C02 Department Headquarters – Ministry of Public Security;
    • C04 Department Headquarters – Ministry of Public Security;

    • Sky Park Residence;
    • Eco Green City;
    • Pac Bo Hotel;
    • Hilton Ha Long Hotel;
    • Muong Thanh hotels and high-rise apartments nationwide.

    Working on many building types gives CPM more experience in organising and meeting different requirements.

    A hotel project has its own aesthetic challenges. An office building needs solutions suited to its architecture and operation. Meanwhile, a public or infrastructure project has different demands on schedule, procedures and coordination.

    With every project, the CPM team gains more hands-on experience and uses it as the foundation for the next.

    Working alongside clients and partners

    On its journey, CPM has had the opportunity to work with many major groups, developers and companies in the market.

    Featured clients and partners include:

    • Sunshine Group;

    • HUD;
    • Hai Dang Tower;
    • Complex Phuong Bac Co., Ltd.;
    • Viet Hung Real Estate & Construction Co., Ltd.;
    • And many other developers and partners.

    For CPM, every collaboration is a test of real capability – not only in design or production, but in coordination, responsiveness, schedule management and sustained responsibility throughout the project.

    CPM always values its clients' trust, because it cannot be built in a day. Trust can only be earned through real results, consistency in the way we work and responsibility for every commitment.

    A vision of becoming a professional aluminium & glass contractor

    In its strategic direction for 2020 – 2030, CPM aims to become one of the leading professional and reputable aluminium & glass contractors in Vietnam.

    To achieve this, CPM is developing in an integrated way the foundations of People – Technology – Factory – Management – Quality – Safety.

    CPM aims not only to grow in scale but to deepen its expertise and ability to deliver solutions. The company continues to invest

    in machinery, refine its management system, raise the quality of its team and take a more proactive role in projects with ever higher technical demands.

    Beyond the domestic market, CPM is also laying the groundwork to widen collaboration opportunities and strengthen its brand in the future.

    Our mission to create sustainable buildings

    CPM aims to contribute buildings to society that apply modern technology and meet requirements for schedule, quality and aesthetics.

    For clients, CPM wants to deliver sensible, integrated and buildable solutions.

    For partners, CPM values transparency, responsibility and long-term collaboration.

    For its people, CPM aims to build a happy workplace where every member can work with peace of mind, grow and contribute.

    This is how CPM builds the foundation for sustainable growth.

    Three values CPM always pursues

    Reputation

    Reputation is built by keeping our word and taking responsibility for every commitment.

    For CPM, reputation is not a slogan but the result of more than 20 years of work with many developers, partners and projects. Every project delivered is another step in building that value.

    Quality

    Quality lies not only in the final product but begins with how we advise, design, select materials, organise production and install on site.

    That is why CPM controls every step of the delivery chain. Only when every link meets the requirements can the final building achieve the desired quality.

    Efficiency

    A good solution must not only meet technical and aesthetic requirements but also fit the realities of production, installation, schedule and the project's investment conditions.

    CPM always seeks solutions that balance Engineering – Aesthetics – Quality – Schedule – Delivery efficiency.

    CPM – More than 20 years of building trust

    The journey from 2004 to today has been one of constant learning, change and improvement for CPM.

    From a construction company, CPM has grown into a firm able to consult, design, fabricate and install integrated aluminium & glass systems for many different types of buildings.

    Behind every project is the contribution of a whole team: the leadership setting direction, engineers researching solutions, factory staff controlling every production step and installation crews working directly on site. Supporting them all is a management system that connects every department in one unified process.

    CPM understands that every new project is a new challenge, but also an opportunity to prove its capability, improve its systems and create better value.

    With the motto “REPUTATION – QUALITY – EFFICIENCY”, CPM is ready to work alongside developers, clients, consultants and partners on the projects to come.

    CPM wants to be not just a contractor on a project but a partner that can work alongside clients, share responsibility and find the right solutions together.

  • Dấu ấn CPM Hà Nội tại những công trình quy mô lớn

    CPM Hanoi's mark on large-scale projects

    The projects that define CPM Hanoi

    In construction, a contractor's capability is shown not only by years in business or factory size. The real projects a company has delivered are among the clearest proof of its organisation, engineering and coordination.

    For CPM Hanoi, more than two decades of growth have spanned many building types: from high-rise housing, mega-cities and resort hotels to cultural centres, technology buildings and aviation infrastructure.

    Aluminium & glass and façades in particular directly shape a building's architectural appearance. Behind the large glass surfaces, doors, balustrades, louvres and façade envelopes lies a whole process from studying drawings and selecting materials to fabrication, quality control and on-site installation.

    The list below presents 10 featured projects that clearly show the scope of capability and experience CPM has built up over the years.

    1. Terminal T2 Expansion – Noi Bai International Airport

    International Passenger Terminal T2 is one of Vietnam's most important aviation infrastructure projects and a major international gateway to Hanoi.

    The T2 expansion increased the terminal's total floor area to over 200.000 m², raising capacity from about 10 million to 15 million passengers per year, with the ability to serve up to 18 million passengers. Aircraft gates, passenger boarding bridges and many passenger facilities were also expanded and modernised.

    More than a transport building, Terminal T2 places high demands on architecture, operability, durability and finish quality.

    On this project, CPM supplied and installed door and glass wall systems during 2024–2025.

    Taking part in an aviation infrastructure project with specific requirements is a notable milestone in CPM's capability profile. It is not only about construction volume but also reflects the ability to meet processes, quality and coordination on a large operational facility.

    For CPM, Noi Bai Terminal T2 is one of the landmark projects reflecting its expansion from residential and commercial projects into high-standard infrastructure and public buildings.

    2. National Innovation Center – NIC Hoa Lac

    If Terminal T2 represents transport infrastructure, then National Innovation Center – NIC Hoa Lac holds a special place in Vietnam's science, technology and innovation ecosystem.

    NIC Hoa Lac has a total working floor area of nearly 20.000 m², comprising two office blocks and an international convention centre. Total construction cost was about VND 750

    billion. The architecture takes the form of an eagle taking flight, conveying the growth and global ambition of Vietnam's innovation ecosystem.

    During construction, CPM supplied materials and labour for the aluminium & glass package during 2022–2023.

    For a building with such distinctive architecture as NIC, the aluminium & glass system not only encloses the building but also helps shape its modern architectural language.

    CPM's presence on this project reflects the company's experience on high-profile buildings that demand coordination between architecture, engineering and finish quality.

    3. Hanoi Children's Palace

    Hanoi Children's Palace is one of the capital's key cultural and social projects of the 2020–2025 period.

    The building sits on a site of nearly 40.000 m², with a built area of over 10,000 m² and total investment of about VND 1,300 billion. It houses many functional spaces such as an 800-seat theatre, cinema, sports hall, swimming pool, library, study areas and an astronomy tower.

    Hanoi Children's Palace was inaugurated and opened in 2024, becoming one of the city's most notable public buildings.

    On this project, CPM supplied labour, equipment and materials for the aluminium & glass works and aluminium doors.

    Unlike ordinary residential projects, a cultural building has many functional spaces requiring a harmonious combination of architecture, function and aesthetics. Taking part in Hanoi Children's Palace is therefore a notable mark in CPM's public building portfolio.

    It also demonstrates the company's adaptability in delivering aluminium & glass works across many different building types.

    4. Dream City Hung Yen – Vinhomes Ocean Park 2

    Dream City Hung Yen, later developed under the name Vinhomes Ocean Park 2, is a large mega-city in Van Giang, Hung Yen.

    The project covers a total area of approximately 460 ha, including many types of housing, retail, amenities and urban landscape.

    What makes it special for CPM's capability profile is not only the overall scale of the project but also the volume of work the company delivered directly.

    According to CPM's records, the company worked on packages supplying and installing aluminium & glass systems in several sub-zones, covering respectively 1,112 units and 724 units. The total recorded scope reached 1,836 homes.

    This figure is highly significant when assessing production and installation capacity.

    Unlike a single building, thousands of homes require the contractor to simultaneously manage output, consistency, supply planning, workforce, schedule and quality control.

    This makes Dream City Hung Yen one of the best projects to demonstrate CPM's capacity for large-scale aluminium & glass delivery.

    5. Vinhomes Ocean Park

    Vinhomes Ocean Park is one of the largest mega-cities in eastern Hanoi.

    The whole project covers approximately 420 ha, with a building density of nearly 19%. Of this, 117 ha is dedicated to greenery, parks and water, highlighted by a 6.1 ha saltwater lagoon and a 24.5 ha central lake.

    The master plan includes dozens of apartment towers and low-rise housing with integrated retail, education and amenity systems.

    In this mega-city, CPM supplied and installed the aluminium & glass system for towers S1.03 and S1.11 in 2019.

    Taking part in Vinhomes Ocean Park shows that CPM has experience working within the mega-city model – where a contractor must not only finish its product but also keep pace with the overall schedule of many works at once.

    For the CPM brand, this is a project of value both in practical capability and market recognition.

    6. Vinhomes Smart City

    If Vinhomes Ocean Park represents the eastern mega-city, then Vinhomes Smart City is one of the standout projects in western Hanoi.

    The project covers 280 ha, with a building density of about 14.7%, comprising high-rise and low-rise housing and extensive landscaped and amenity spaces. According to Vinhomes' official information, the project develops 58 towers along with villa and shophouse areas.

    At Vinhomes Smart City, CPM supplied and installed the aluminium & glass system for tower H1 in 2019.

    Large urban projects demand consistency across thousands of components, strong production management and installation plans aligned with the overall site schedule.

    Experience at Vinhomes Smart City and other Vinhomes projects forms an important part of CPM's capability profile in high-rise residential.

    It is also a foundation for the company to keep expanding its capacity for ever larger projects.

    7. Crystal Holidays Harbour Van Don

    Among the resort projects CPM has worked on, Crystal Holidays Harbour Van Don stands out in both scale and scope of work.

    The complex is located in the Van Don Economic Zone on Bai Tu Long Bay. According to the developer, total investment exceeds VND 5,500 billion, comprising 5 towers, more than 2,000 hotel rooms and serviced apartments and an international convention centre with around 1,500 seats.

    In particular, on this project, CPM designed and completed the exterior aluminium & glass system for Block F during 2025–2026.

    Compared with packages focused only on doors or glass walls, a scope directly involving the building exterior shows more clearly the technical capability of a façade contractor.

    The façade is the architectural layer that defines a building's identity, while simultaneously resolving requirements for design, materials, connections, installation and aesthetics.

    For this reason, Crystal Holidays Harbour Van Don is one of the projects CPM should feature first to demonstrate its in-depth expertise in aluminium & glass façades.

    8. DoubleTree by Hilton Ha Long Bay

    DoubleTree by Hilton Ha Long Bay Hotel & Condotel is a large hotel and resort development in Bai Chay, Ha Long.

    According to Coteccons, the project has a total floor area of nearly 100.000 m², with two high-rise blocks for the hotel and serviced apartments.

    B+H Architects, responsible for the master planning, architecture, landscape and interiors, reported total investment of about VND 2,000 billion. The building is designed to maximise views of Ha Long Bay, with hotel rooms, serviced apartments, conference and resort amenities.

    On this project, CPM supplied and installed the aluminium & glass system and exterior cladding during 2020–2021.

    This scope directly shapes the building's external architectural form.

    Working on an internationally branded hotel in a major tourist hub like Ha Long adds a significant mark to CPM's experience in the high-rise hotel & resort segment.

    9. NovaWorld Ho Tram – The Tropicana

    Beyond its many projects in Hanoi and the North, CPM also has experience on large projects in the South.

    A typical example is NovaWorld Ho Tram – The Tropicana.

    According to Novaland's 2025 Annual Report, the whole NovaWorld Ho Tram resort city covers nearly 1.000 ha, stretching along about 30 km of coastline and developed in several resort phases, including The Tropicana.

    In this phase, CPM supplied and installed the aluminium & glass works in 2021.

    Coastal resort projects have particular requirements for materials and construction solutions due to environmental and climatic exposure, as well as high architectural expectations.

    CPM's work on The Tropicana shows that the company's reach is not limited to one region, and reflects its ability to serve large-scale resort real estate projects.

    It is also one of the projects that makes CPM's portfolio more diverse in type, location and segment.

    10. Sunshine Crystal River – Noble Crystal Tay Ho

    Located in the Ciputra – Tay Ho area, Sunshine Crystal River, now marketed as Noble Crystal Tay Ho, is a high-end real estate development in Hanoi.

    According to the developer, the project covers approximately 50.850 m², comprising 5 towers of 40 floors and 60 low-rise villas.

    High-rise architecture with large glazed areas, balustrades and exterior components places significant demands on precision and finish quality.

    On this project, CPM supplied and installed glass walls, glass balustrades, louvres and glass roofs for towers S4 and S5 in 2026.

    This scope covers many key components of the architectural envelope, demonstrating CPM's aluminium & glass capabilities on high-rise buildings.

    Beyond its scale, the West Lake location and high-end positioning make the project a fitting highlight in CPM's featured project portfolio.

    More than 20 years of building trust through real projects

    Founded in 2004, Ha Noi CPM Construction Corporation has more than two decades of experience in consulting, designing, fabricating and installing aluminium & glass systems.

    Behind the project portfolio is a coordinated capability built on engineers and technical specialists, a factory of over 1 ha with average capacity of around 15,000 m²/month and an ISO 9001:2015 quality management system.

    These factors enable CPM to take on projects of ever greater scale and technical demand.

    From housing and urban developments to hotels, cultural centres and national infrastructure, each project is another step for CPM to refine its capability and prove its responsibility through real work.

    With the motto “REPUTATION – QUALITY – EFFICIENCY”, CPM aims to be not only a supplier of aluminium & glass products but also a technical partner able to work alongside developers, consultants and general contractors from solution to delivery.

    This is also the foundation for Ha Noi CPM Construction Corporation to keep extending its mark on new projects, helping create modern, high-quality and sustainable architecture across Vietnam.

    Analysis of Pressure-Equalized Solutions & Rainwater Penetration Prevention on Unitized Façades

    Pressure Equalization Chamber – PEC

    In the envelopes of skyscrapers, rainwater leakage does not simply come from open cracks; it is the inevitable result of fluid dynamics when three conditions are present together: (1) Surface water, (2) Gaps in the material, and (3) A driving force (the pressure difference between outside and inside the building).

    Traditional face-sealed silicone systems (Barrier Wall Systems) often deteriorate quickly after 3 – 5 years due to UV, wind vibration and thermal expansion. That is why the CPM Unitized façade fully applies the principle of Rainscreen & Pressure-Equalized.

    Formula for eliminating the penetration force:

    ΔP = Poutside (dynamic wind) – Pbuffer cavity (PEC) → 0 (Pa)

    When the air pressure inside the cavity (PEC) instantly equals the gusting wind pressure outside the glass, the driving pressure difference ΔP becomes 0. Rainwater on the aluminium ledges loses the energy to travel further inside and falls freely into the drainage channel.
