Embodiment two
Corresponding with above-described embodiment one, the present embodiment proposes a kind of construction work calculation amount and valuation methods, and refer to Fig. 2, it mainly comprises the following steps:
S100, from architecture information document, identify BIM object, and by building system project corresponding in master data base and described BIM object association.
Be preferably in step S100: automatically identified the BIM object in architecture information document by Object Selection collection formula, and by the coding of building system project corresponding in master data base and described BIM object association.Be exemplified below:
Object Selection collection formula can be configured in advance in master data base, the sample of formula literary style is as Object (cpiComponentType==" wall "), when user selects association, the BIM object in architecture information document can be automatically identified and automatically distribute association building system project for it, if this BIM is to liking wall (i.e. wall), then by the coding of the building system project of correspondence and this BIM object association, such as being distributed to by coding 01.187 is all BIM objects of wall (i.e. wall).
In addition, the mode such as manually can also be adopted to realize association, such as on system software window, the building system project chosen directly " is dragged " on the window of BIM object (such as supposing that this window shows the figure of a width wall) by user, then the coding assignment of this building system project associates to this BIM object by system automatically.
S200, the structure item corresponding according to described building system project obtain every structural parameters of described BIM object.
Specifically according to the computing formula of counter structure item in building system project, every structural parameters of described BIM object can be automatically read in step S200.
Same for " walling ", the structure item of its correspondence comprises length, and the computing formula at this moment by correspondence reads or calculates every structural parameters from BIM.Such as use computing formula Var_Obj (" length ", m, cpivar) that the length information of wall will be returned.
Other modes also can be adopted in step 200 to obtain every structural parameters, such as, on system software window, based on question and answer mode typing, read every structural parameters of user's counter structure item typing in building system project.
For " walling ", namely on software window with field and fill in the mode that frame combines and carry out " question and answer ", user inputs counter structure parameter in corresponding the filling in frame of (field) length.
S300, the every structural parameters generation parameter list file that will obtain.
In step S00, the every structural parameters obtained are generated parameter list file, so that the calculation services of master data base (being equivalent to the parsing module 30 in embodiment one here) is done estimation and is prepared, it is streamed that this parameter list file can be packaged into XML data, be packaged into service call parameter, transfer to calculation services.
S400, described parameter list file to be resolved, and determine the calculation process that described building system project is corresponding.
In step S400, the calculation services of master data base is resolved XML data stream, can obtain the coding of building system project and determine corresponding calculation process.
S500, according to analysis result and described calculation process estimation quantities, and in cargo tracer valency catalog data base, the price of required buildings and resources is evaluated, and incorporation engineering amount and rating result generate quantities and appraisal inventory.
In step S500, as foregoing description, building system project definition has calculation process, parse the coding of building system project in calculation services after, just may correspond to and read its calculation process, and carry out calculation quantities calculation amount and appraisal in conjunction with every structural parameters, unit price catalog data base, then generate quantities and appraisal inventory, in this inventory, include multiple listing entries.Be exemplified below:
Suppose that a building system project is defined as follows:
Parameter: length (Length), width (Width), highly (Height), volume (Volume)
Formula: volume (F1)=Length*Width*Height
It is high that dimension: D1{1 represents the wide * of long *, and other expressions directly read Volume}
Specification: S1 use what brick 1, common brick; 2, cement brick; 3, blue bricks }
List: T1{ is associated with 2230.011 engineering entries }
T11, reading dimension D1, if 1, so just representative is calculated by length, just goes to read this formula of F1 and the length obtained in the parameter list file parsed, calculates volume.
The bill of quantities entry item code 2230.011 of the definition in T12, reading list T1, generates bill of quantities entry in conjunction with the volume calculated.
T13, reading specification S1, detect it is use common brick, so cargo tracer valency catalog data base, obtain common brick resource entries, associate with the listing entries of harsh one-tenth.
Arrive this, simple quantities calculation amount, cost estimate just complete.If the words of more complicated operation are corresponding have more complicated definition.Multiple list can be defined inside a building system project, also can other building system projects nested.
In the present embodiment, in order to adapt to further needs, further comprises and quantities and appraisal inventory are sorted the step gathered.This is because, the data of the quantities generated in step S500 and appraisal inventory are flattenings store (being different from tree-like storage), but usually when building trade or bid, need to carry out collating sort according to different structures.Such as user wants to remove classification and ordination cost information according to floor, so preferably gather sequence together what all belong to Stall, obtain the structure of Stall, price and inventory.
Particularly, the present embodiment comprises step S600 further:
S600, carry out sequence according to the level in quantities and appraisal inventory belonging to each entry and gather, generate final quantities and appraisal inventory.
