Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building design support device, an architect support terminal, a building design support server, a contractor support terminal, and a building design support method which can be used by this device. The present invention particularly relates to a technique for supporting designing by connecting architects and contractors with a network.

2. Description of the Related Art In recent years, as personal values have diversified, demands for individuality and safety have also increased for home building. Considering the housing situation in Japan, which cannot be said to be rich, building a house is a big event that will never happen in a lifetime, and cost-oriented, mass-production techniques are not generally preferred.
Housing manufacturers try to reduce costs by sharing all aspects of design, materials, processes, etc., but in many cases this leads to uniform design. It has long been the case for owners who are unsatisfied with such house-building to ask an architect to design for the purpose of pursuing an original design, but it is considered that such a tendency will become more prominent in the future.

[0003]

In the conventional general design procedure by an architect, first, a detailed design including drawings is completed. At this stage, the ideals of the owner and the architect are reflected to a large extent. This design drawing is handed over to the contractor who undertakes the construction work, and the detailed construction cost estimate is fixed only here.

Although architects can understand the construction cost to some extent by experience, the construction cost often greatly exceeds the budget of the owner in order to realize the wishes of the owner and to pursue expression as a creator.
As a result, the owner was forced to make a compromise in building a house that is a lifelong life, and the architect had to undergo a major design review.
The difficult and difficult work will be repeated until the quotation is within the budget. The reality of deviating from the ideal home is inevitable in terms of trust in the architect, and the architect experiences severe boarding between the owner, the contractor, and his own pride. .

Originally, the architect should always proceed with the design while always grasping the estimated cost, but the architect usually does not have the standard of the material cost and the construction cost, and the contractor However, the contractor's estimate is based on a fairly safe side, and the contractor's estimate is somewhat "quoted", so it cannot be said that the responsibility of the architect is always the only responsibility. Absent. If the contractor is required to cut costs unnecessarily in order to close the gap between the budget and the estimate, the so-called "cut-out work" becomes a concern for the owner.

The present inventor has made the present invention based on the above recognition, and an object of the present invention is to provide a technique for facilitating from the design of a building to the estimation thereof. That is, the final object of the present invention is to establish a architect's design drawing with high accuracy against the budget, shorten the construction period, and make the house more satisfying for all owners, architects, and contractors. It is possible to focus.

When inputting the work contents later, the materials that have been narrowed down in advance are presented as selection candidates in the menu, and the selection is made from among them. As a result, it is possible to input a design without designating a large number of material combinations for each building site. It is said that there are not so many types of materials used for one building, and it is expected that a significant improvement in work efficiency can be expected by narrowing down in advance. The "building site" may indicate a construction site such as "wall" or "floor".

The "architect's point of view" means that data is entered in a form that is easy for the architect to enter.

BEST MODE FOR CARRYING OUT THE INVENTION The architectural design support system of the present embodiment saves time, money, and labor by supporting the work of an architect and a contractor from the design of a building to the estimation thereof. To do.

The architect is provided with a cumulative format that can be input at the basic design stage to assist in detailed design. Conventional counting software was made for contractors or counting offices and was premised on input after completion of drawings. In addition, even if the architect himself entered, it was not possible to grasp the detailed cost. According to the integration format of this embodiment, the architect can create the data necessary for the estimation and the detailed design almost at the same time by selecting the items according to the image drawn in his head. The integrated data input according to the integrated format can be grouped into each room, each building site, each material, etc., which facilitates subsequent processes such as design change and cost grasp.

Since the accumulated data is automatically sent to a plurality of contractors and building material makers, the architect is freed from the selection of contractors and the management of enormous maker information, which had been done for each area of the construction site.

The integrated data is provided to the contractor. At this time, the quotation will be helped by converting it into a format that is easy to input and then presenting it to the contractor. The contractor can basically create an estimate by inputting the unit price for each material. Costs will be made transparent and appropriate by collecting quotations from multiple contractors and providing them to architects in a form that compares them.

Regarding custom-made building materials, we will seek cost transparency and optimization by collecting quotations from multiple building material manufacturers. In the past, material costs and construction costs were often high regardless of performance, and it was inevitable to leave it to the contractor from cost setting to selecting a subcontractor. This system eliminates the so-called material engineering set, and changes the structure that has been based on the theory of the creator side to the structure that is based on the theory of the owner side.
