Introduction to estimating and planning

Understanding the production and delivery of cost information The QS/cost manager needs to understand how a model, its attributes and other data will be created and conveyed at different stages of the project life. This will enable the QS/cost manager to make suitable adjustments to quantities, rates and other ancillary costs and modifications, at each… read more »

Understanding the role of the quantity surveyor in BIM

It is important to understand how the role of the quantity surveyor could change or adapt in the future; this is because the direction of the industry is still being defined and developed in line with UK standards level 2 and 3 principles of BIM. Henry Riley research took the approach to develop a number… read more »

Objects and naming conventions for a QS

Objects and naming conventions Rather than permitting object naming to follow the typical conventions of the particular design practice responsible, or even to follow the standard families systems in design packages such as AutodeskĀ® RevitĀ® software products, it is important to agree at project inception how model objects will be named to allow them to… read more »

Using Automatic Quantification Tools

Using BIM quantification tools This approach associates with the use of specialised Quantity TakeOff (QTO) software, e.g. Autodesk QTO, Vico Office, and Exactal CostX, that transfer the BIM models and their embedded information from BIM design tools into their system. Similar to the previous approach, these tools can support both the automated extraction and manual… read more »

BIM Object detail versus cost detail

Object detail versus cost detail An important aspect to consider is how the designed objects integrate with the required cost detail. Taking the example of a concrete slab, if the costing document being used simply provides a line item for a slab there is little point in modelling a detailed build-up of all associated elements…. read more »

Tender Inclusions

Within the tender documents issued, additional BIM outputs from the various models produced were included. While it did not seem prudent to burden the contractors with additional expense during a tender period where they were already required to interpret information in a form that they had not previously received, it was important to obtain as… read more »

Post-tender review

Mid-tender interview feedback Two clear themes were identified during the mid-tender interviews: use of the BIM model; and having the correct tools and technologies. During the interviews with the various contractors it became evident that the contractor base was struggling to view and understand the 3D models. Requests for PDFs and hard-copy print outs were… read more »

Elemental costing for design and construction

Cost plans are generally prepared by cost consultants (often quantity surveyors). They evolve through the life of the project, developing in detail and accuracy as more information becomes available about the nature of the design, and then actual prices are provided by specialist contractors, contractors and suppliers. They range from very early initial cost appraisals… read more »

Review on BIM Based Estimating Tools

The following seven criteria have been developed for the review on the selected BIM estimating tools. Model information exchange (Exchange) – file types or formats of BIM models that can be supported by the tools. This criterion investigates whether the software tools are capable of supporting the original Revit model directly or an exported model… read more »
