Design Consultancy

01ARCHITECTURAL DESIGN CONSULTANCY

An excellent architectural design must combine the core elements of interior, exterior, landscape, surroundings and economic optimalization for the Investor. The architectural design consultants of NORA are strongly confident to meet key factors to bring an optimal and perfect product to clients.

Keeping track of the latest interior design trend with the best solution in materials, color mixture and feng shui, NORA highly commits to create comfortable working and living spaces for the valued clients.

Conducting a thorough studying and analysis on the factors which have a great impact on the lanscapde of a building such as materials, shape, structure, using capacity and the most important is the regional culture values. All of these make the different values for NORA compared to rival companies in the industry.

We always pay high attention to the sustainability of any projects. Apart from high quality and cost-saving, the environmental friendliness is also one of the priorities in any design projects of NORA.

NORA team knows how to have a harmony combination of the natural elements to bring an extraordinary and brand-new looking for the project right from the outside.

02OVERALL STRUCTURE DESIGN CONSULTANCY

NORA designers are the ones who have a wealth of experience and expertise in overall structure design. We always support the Investor and the related parties by consulting the best solution from the ground, foundation to the roof of a building. NORA team will conduct the overall structure design as soon as the architectural solution is approved.

The architectural and structural teams of NORA have a good cooperation during the execution process so that we can meet any arising requirements from the clients. As a result, the completed design product can definitely satisfy the clients.

As a leading post-tensioning consultancy, NORA deeply understands the interaction between the related structures by a thorough consideration on bearing capacity. The design supervision and construction process for the whole project are accordingly conducted in the way of optimal expenses and sustainability.

03POST-TENSIONING STRUCTURE DESIGN CONSULTANCY

HIGH-RISE BUILDING, FACTORY

With deep expertise and rich experience proven through hundreds of design & build projects, NORA team is not only applying the optimal solutions but also taking advantage of strong points of various type of post-tensioning slabs to meet all strict requirements on architecture and structure for the buildings.

HIGH-RISE BUILDING, FACTORY

In the cases of complex buildings, high-rise buildings, hotels or hospital…, it is sometimes needed to transfer at a certain level, some of the vertical loads to other alignments so as to obtain longer spans at lower levels, which brings a much larger spaces for public buildings project.

The transition from the smallest grid structures to larger column spacing is done by means of a transfer structure (with transfer beams or slabs). Post-tensioning solution is absolutely a very effective way to perform a transfer beam or transfer slab with smaller dimension and better deflection control compared to conventional reinforcement concrete beam or slab. Post-tensioned transfer beam/slab is required a high accuracy in design by checking every complex detail using calculation model and other methods to have a better arrangement plan for transfer beam and slab.

For post-tensioned transfer beam/slab, the volume of conventional reinforcement needed for flexion design is drastically reduced; the arrangement is simplified and any early shrinkage cracking in concrete is effectively controlled.

FACTORY, VILLA SLABS

Post-tensioning beam/slab (foundation) on grade is widely applied in the industrial floor slab, villa floor slab (separated villa) for high economic efficiency and bearing capacity. Furthermore, it helps to reduce maintenance and repairing costs.

Post-tensioning beam/slab (foundation) on grade is often replaced a deep foundation for the strongly and moderately structured ground. This method increases the working efficiency of the slab compared to the conventional one with reinforced concrete due to thinner slab thickness, less rebar and concrete, dismiss or reduce thormajoint and have a good control on cracking.

Advantages of applying post-tensioning technique in Silo/Tank design:

  • It provides the required resistance to the acting forces.
  • It makes possible solutions more economic than those achievable with reinforced concrete or steel.
  • • It renders the concrete virtually free of cracks.

  • Cedrus (building and slab)
  • Statik (frame analysis)
  • Plaxis (geotechnique and geoengineering)
  • Fagus (section analysis)
  • Staad Pro
  • Etab
  • Revit

Post tensioning solution is ideally suited for pre-stressing long span girder at the site of construction, or bridge pier segment, without the need of costly factory type installations like pre-tensioning beds. Post-tensioning technique is also an optimal solution for skytrain segment construction which is constructed by pre-tensioning technique and then combine into an integrated structure.

Post-tensioning system makes it possible to bring cost-effective solution in bridge construction, along with long spans, high intrinsic durability and enable to construct quickly, limit cracking, reduce structural depth and save maintenance cost.

04DESIGN CONSULTANCY ON FOUNDATION CONSTRUCTION

Foundation structure (consisting of retaining wall, stressed pile, bore pile, soil digging, etc.) accounts for a majority of total construction cost and workload in the design process. Foundation construction is in direct relation to geographic elements such as soil, underwater, and the foundation structure stability has a huge impact of safety and service life of the building as well as the surroundings.

NORA team, with a wealth of experiences, always proposes the best optimal design solution for the building of which the foundation design solution must comply with architectural conditions, construction conditions in reality, and construction method is feasible.

Depending on particular building conditions, NORA will take a thorough consideration to choose the most suitable type of foundation such as flat foundation, pile foundation, multi-shaped stressed piles and bored piles with various diameters.
Besides, NORA can propose a combination of strengthening methods by cajeput, geotextile, jet grouting or ground engineering.

05GROUND ANCHORAGE DESIGN CONSULTANCY

06SOLUTION DESIGN FOR MODIFICATIONS, REPAIRS AND STRENGTHENING

It is many times required that modification has to be considered should arise any changes in building use or changes to the building codes. These modifications could involve cutting openings, such as those for stairs, elevators, and escalators, without generating any problem to existing structure.

Therefore, during the researching process, NORA team has succeeded in applying post-tensioned slab-cutting solution by Zip Anchorage system to modify using capacity of the building.

In the design process, calculation is always required a high accuracy in every step, especially at the position of modified using capacity, checking all deflection conditions, shearing resistance of the structure to propose the best modification solution. Apart from this, it is necessary to calculate and arrange rebars at the position of modified using capacity for increasing bearing capacity and service life of the building.

Many unexpected problems may occur during the construction process which can have a bad influence on the structure of slab, column, wall or other related structures. In these cases, it is required to conduct technical examination and calculation to carry out the most suitable, safest and most optimal solution.

In various cases, changing architectural design for a better aesthetic quality may require the existing structures to be strengthened for a better bearing capacity and other requirements on design.

NORA team will conduct a thorough investigation on design documents to be able to propose the best solution for the existing beam, slab and columns. Furthermore, if the construction method is not conducted correctly, the structure is damaged or an unexpected problem arising from the design process, external post-tensioning is the optimal solution to strengthen the structure.

External post-tensioning is a very useful method with time-saving, convenience in checking and repairing and easy to find out the problems and fix them promptly. However, it always needs to be carried out correctly by a professional design team who are complying with strict design standards and have an accurate calculation for the structure to have a better service life.
