You are standing in front of a fully fitted door. The job is done, and now you need to sign off on the inspection. Does the number on the door match the one in the BIM model? At Norwegian regional general contractor \u00c5sen & \u00d8vrelid, this verification is built into the checklist in StreamBIM.<\/h5><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

West-Norwegian GC \u00c5sen & \u00d8vrelid is a stellar example of how a mid-sized contractor can implement digital construction tools and workflows.<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The person carrying out the inspection opens the checklist from the door\u2019s object in StreamBIM. The checklist retrieves the door number from there, and the inspector records the number on the installed door. If the numbers do not match, this is highlighted in the inspection overview. The site manager can locate the relevant door in the model when the discrepancy needs to be clarified with the fitter.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\u00c5sen & \u00d8vrelid can also save a checklist response as a property of the object in StreamBIM. The site management team can then view the completion status using colour coding in the model. On a floor with many identical doors, the site manager can thus schedule the next round of checks for those doors that still need to be inspected or approved.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The door inspection works because the door number is stored in the discipline model. When mechanically finalising the ventilation system, the team also needs to know which system the component belongs to. That is why \u00c5sen & \u00d8vrelid use IDs for both the component and the system when selecting which objects a checklist should apply to.<\/p><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

For the contractor, this provides a concrete starting point for ordering BIM data. Clarify what the team needs to be able to look up on site, and use this to set requirements for the consultants. \u00c5sen & \u00d8vrelid use POFIN as a basis for describing the information requirements and use IDS to automatically check whether the IFC models contain the agreed information. When discipline-specific models are delivered with the same structure from project to project, it also becomes easier to reuse the checklists.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The same door after handover<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Imagine that the same door starts to rattle in its frame after handover. If the door number and inspection result are linked to the door in the model and are included in the handover for management, operation and maintenance (MOM), the operations staff can look up the door and see what was checked before the building was put into use. This provides a better starting point when investigating the fault and arranging a service call.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The client and the contractor must therefore agree at an early stage on what information is to accompany the door. The contractor can then record this information as the work progresses, and the client can use it during operation. This is the idea behind TotalBIM. A usable O&M handover takes shape whilst the person familiar with the work is still standing by the door.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

How does \u00c5sen & \u00d8vrelid use StreamBIM for door checks?<\/h3>

\u00c5sen & \u00d8vrelid opens the checklist from the door\u2019s object in StreamBIM. The checklist retrieves the door number from the model, and the person carrying out the check records the number of the fitted door. If the numbers do not match, this is highlighted in the inspection overview. The site manager can locate the door in the model and follow up the discrepancy with the fitter.

How does the site management team see which doors remain to be inspected?<\/h3>

In StreamBIM, a checklist response can be saved as a property of the model object. \u00c5sen & \u00d8vrelid can use this value to display the completion status using colours in the model. This allows the site manager to see which doors are recorded as completed, checked or approved, and to plan the next inspection round.

<\/p>

What BIM data is required for the systematic completion of ventilation?<\/h3>

\u00c5sen & \u00d8vrelid use an instance ID for the component (RefCompOcc) and an instance ID for the system (RefPriSysOcc). These identifiers make it possible to select which components in a ventilation system a checklist should apply to. The project must agree on what information the consultants are to provide before the checklists are put into use.

<\/p>

What is the difference between POFIN, IFC and IDS?<\/h3>

POFIN is buildingSMART Norway\u2019s framework for describing and monitoring information requirements. IFC is an open standard for the exchange of BIM data. IDS (Information Delivery Specification) enables information requirements to be formulated in a machine-readable format and allows verification of whether agreed properties and values have been delivered in an IFC model. buildingSMART Norway on POFIN<\/a> \/ buildingSMART International on IDS<\/a>

How can a door inspection carried out on site be used in operations and maintenance?<\/h3>

If the door number, inspection result and relevant documentation are linked to the door\u2019s object in the agreed operations and maintenance handover, operations staff can locate the door in the model and see what was inspected prior to handover. The client and the contractor should agree at an early stage on the information required by operations staff, so that it is recorded whilst the work is in progress.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
