CONSTRUCTABILITY ISSUES<br />

FOR VARIOUS TRADES WITH<br />

BIM<br />

bringing all project stakeholders on the same platform.<br />

BIM Constructability Review helps in this regard by<br />

acting as a visual tool for managers, field personnel &<br />

other stake holders. Highest level BIM coordination<br />

ensures fast and error free construction, reducing field<br />

generated change orders and rework. Furthermore, installation<br />

disruptions and work stoppages are eliminated. Constructability<br />

issues identified by BIM in electrical trade include adequacy<br />

of space for installation, operation and maintenance, optimum<br />

use of fittings, use of bend radius as per codes, mounting heights<br />

as per codes, clearance between services and locating electrical<br />

items in proper place.<br />

CONCRETE - BIM helps to find several inconsistencies in the<br />

input drawings and incomplete information for concrete trade.<br />

Several conflicts get identified which could have affected the<br />

actual construction in terms of cost, material and manpower.<br />

BIM minimizes wastages by revising designs like changing pouring<br />

sequence, modifying mat slab thickness, terminating floor<br />

opening and more.<br />

HVAC TRADE- BIM coordination helps to identify clash<br />

and raised it to consultants, which results in revision of design.<br />

Coordination problems get resolved through drawing validation<br />

such as flue duct clashing with structure and other trades, FPB<br />

clash with wall and structure and more. The final HVAC model is<br />

produced by removing clashes through re-routing and re-sizing<br />

of duct as well as by changing elevation. This helps to pre-fabricate<br />

assemblies in quality set-up, reducing installation time,<br />

wastage and cost.<br />

Seek constructability review through BIM and resolve clashes<br />

before construction. Constructability review and clash detection<br />

analysis are often performed with software like Autodesk<br />

design review, Navisworks and more. Choose a proficient BIM<br />

service provider to identify construction conflicts and fix them<br />

efficiently. BIM visual analysis helps to achieve building safety<br />

standards, enabling visualization of schedule with installation<br />

of permanent building parts & temporary safety arrangements<br />

before construction. Implement BIM to match your construction<br />

workflow in the perfect way.<br />
