Services Design Review and Value Engineering

Design Reviews & Value Engineering

Design reviews undertaken by third parties play an important role to guarantee the safety of building structures and safely prevent hazards. gbc engineers serves as an independent engineering consultant who reviews structural design calculations, technical specification documents and construction drawings done by others. We further support our Clients with independent site supervision services to ensure the quality of construction on site. 


  • Review and assessment of structural calculations (RC structures, steel structures, timber structures for new and existing buildings)
  • Independent re-analysis of building structure considering linear and non-linear material and geometry behavior
  • Verification of structural design in accordance with Eurocode, British Standard, American Standard or Vietnamese Standard
  • Examination of long-term deflections of beams and slabs to prevent defects in the interior (tiles, partition walls, glass elements)
  • Assessment of concept designs and feasibility studies
  • Assessment of detailed design drawings and shop drawings for construction
  • Inspection and site supervision services in Ho Chi Minh City, Vietnam and Phnom Penh, Cambodia


  • Detailed report on assessment indicating results of the review
  • Provision of defects and errors in the existing design (if any)
  • Provision of design improvements indicating alternative structural design options

Value Engineering

Value Engineering Design is a systematic methodology used to identify and eliminate unnecessary construction costs and reduce construction time, while maintaining or improving the function and quality of the building structure.

Our aim is to support Architects and Contractors in Ho Chi Minh City, Vietnam and Phnom Penh, Cambodia with our engineering expertise particularly focus on:

  • Increasing project's value by reducing the construction costs or improving the quality of the structure
  • Reducing quantities of materials by re-analyzing the building structure
  • Developing and accessing alternative design solutions to select the most cost-efficient (optimal) design solution
  • Reducing the construction time by reducing quantities of materials and increasing the simplicity of the structure
  • Providing engineering advice on the use of new construction materials and advanced construction methods to reduce construction costs and time


  • Review and evaluation of the existing structural design
  • Re-analysis and optimization of building sections and elements by use of German 2D and 3D FE-Software
  • Linear and non-linear material and geometrical analysis by use of German 2D and 3D FE-Software
  • Assessment of non-linear and long-term material behavior to limit the long-term deflections of i.e. beams and slabs in order to prevent defects and damage to the building interior
  • Determination of design improvements and feasible alterations, determination of the technical and economically optimal structural design solution
  • Implementation of design improvements in close liaison and cooperation with the Architects and Contractors
  • Development of high quality and detailed shop drawings for formwork and reinforcement, structural steel and timber constructions


  • Achievement of technical and economically optimal structural design solution
  • Use of materials with higher quality
  • Forecast/ determination of long-term structural behavior (estimated beam and slab deflection)
  • Improvement and acceleration of Contractor's work progress on site
  • Reduction of construction costs and construction time

We always enjoy exploring limits of rational and economic feasibility. Our design engineers in Ho Chi Minh City and Phnom Penh can rely on our complex Germany computing software.
