The first tower, is designed with 68 floors to save maximum power consumption, will be head office of VietinBank. The second tower with 48 floors will be 5-star hotels, health centre, spa and luxury department for hire.
Building complex system orient with environment friendly, decrease negative effect to environment. Its design use inverter dehumidifier system, which help hygroscopic water, separate water from air and dry air. This air once will be freezed by ground water and turned back into buildings. It saves about 35% as others.
The towers’ architectural concept was designed by
Norman Foster, its technical design development was designed by
Vinaconex R&D.
Turner International is project management consultant. Hoa Binh and Agrimeco are structure contractors joint venture.
REE M&E is MEPF contractor. This building has been constructing the body massive structure and MEPF installation from ground.
2.1. Vietinbank tower perspective back
2.2. The present condition of project in February 2015
Because of the complexity of buildings’ structure and mechanical system, investors and project management consultant required the participants have to integrate BIM into detail design stage, in which the bidders need:
-Have enough employees and tools to BIM implement for performing the required work to the prescribed standards and within the proposed contract period.
-
Design shop-drawing and trades coordination in
3D BIM environment
-Send competency employee work on site to coordinate solving clashes.
-MEPF contractor REE M&E is responsible in setting BIM information system to share and coordinate solving space clashes.
REE M&E is one of top Vietnam competence companies in MEPF construction industry. REE has experiences in doing BIM shop-drawing for some project smaller than this project. But they still have little experience in 3D coordination and modeling in scalable projects.
In period of 4/2014 to 10/2014, BIM research team of Institute of Construction Economies –
Ministry of Construction (ViBIM specialist participated in this team) trained human resource of REE on BIM workflow, created and delivery coordination progress, detailed information on Table 2 below: Coordination progress and detail information in
Vietinbank Tower project
I. Creating 3D coordination standards and progress, training human resource of REE for this progress |
Major task group | Detail of task |
1.1.Creating 3D coordination standards and progress | Creating progress, BIM protocol include: Preparing and meeting for 3D coordination Progress of prevention space clashes among disciplines BIM file naming standard BIM object Colorize Instruction setting general coordinate for 3D modelling Checklist to control quality of file BIM Meeting document sample for BIM coordination A diagram to define detailed role and responsible of participants |
1.2 Training human resource of REE | Training BIM Coordinator human resource of REE to understand and practice follow by step of progress and standard in 1.1. |
Major task group | Detail of task |
2.1. Consult to choice online hosting | Analysing features of online hosting solutions and consult to choose the best one for project and budget |
2.1 Setting online hosting and training on using | Training REE on setting folder structure, decentralization (or not), file naming, version control (or not), synchronization (or not). Instruct REE employees to use and operate. Consult to adjust in implement duration for workflow more efficiently. BIM human resources’ REE can use and operate online hosting to provide BIM services. |
After 2 months training, employees of REE can perform themselves the required works in contract with investor, check list and coordinate to other contractors solved well trade clashes and completed contract period with Turner – project manager consultant.
The table 3 below statistic trade clashes that detected and resolved until 07/2015. In which, there are so many misses in design that can cause large harm for construction if not detect early. For an example is size of hoistway elevators, the issue was concrete hoistway designed smaller than real car specification from supplier.
Table 3. Resume dangerous clashes until 07/2015
