BIM Handbook Chapter 5: BIM for Architects and Engineers.
Reading chapter 5 of the BIM Handbook: A Guide to Building
Information Modeling for Owners, Managers, Designers, Engineers and Contractors
was such a treat for me due to some pre-made ideas that I had about BIM; even
though, I did not agree on the approaches taken for some of the concepts
discussed in the chapter, I must admit that I remain satisfied about the
arguments presented.
In fact, this chapter begins by affirming how BIM is a
paradigm change and redistributes the allocation effort to conceptual design
while providing the following direct benefits: consistency across all drawings
and reports, automating special interference checking, use of interfacing
analysis, simulation, cost application which increases visualization,
communication at all scales and phases of projects.
Throughout this chapter the impacts of BIM on design was presented
using mainly three point of views: conceptual design meaning it becomes easier
to generate complex building shells using BIM, Integration of engineering
services: this could be summarized by the integration of new information with
existing simulation and analysis tools, and Construction-Level Modeling which
addresses potential achievement through collaborative design-construction
process as example with Integrated Project Delivery (IPD). Other facts were discussed such as
evolutionary step to replace 2D drawings with 3D digital models and the
practical concern of design firm when implementing BIM. However, because of
this change, questions such as don’t we believe that the essence of design lay
in the thought processes associated with conveying lines on paper? Don’t drawings
and sketches enhance thinking and creative work? It is no doubt that we have
moved from the age of designs conceptually made in a designer’s head and
recorded externally to the ones created through visual aids and models, but
does this promote the evolution of the human intelligence within this field and
is it the right direction?
Additionally, it was also argued that BIM provides the
implication of all the parties involved in a project biding under one single
collaborative contract (IPD) which guarantees success through common interests,
and the cost of having BIM was presented along with some application libraries,
software and programs such as SketchUp Pro, Bonzai3D, Vector Works, OasisGSA,
Robot, Sofistik, SpaceGass, Revit, Strand7, Rhino.

Abad,
Your overview on chapter 4 of the handbook about BIM for
owners and facility managers have been well-presented. Throughout the chapter,
anyone could see that BIM have provided considerable advantages to the owners
on multiple level such as cost reliability and design assessment; Although, I
totally agree with this fact because it brings the owner closer to the project,
but what are the implications in regard to the designers, engineers and other
parties involved? It is my belief that this would bring some constraints to the
designers.
Chris,
I have enjoyed your approach on BIM for contractors. It reinstates
undoubtedly that BIM promotes team effort, communication, and collaborative
inputs for the realization of projects. I was more interested to the fact that
BIM has clash detection for contractors which is a built-in method to identify when
things are overlapped and can point them out before it’s too late. I would have
appreciated to see any type of illustration on this subject.
Dung,
It was interesting to read your summary on chapter 2 for BIM: Design
Tools and Parametric Modeling; In fact, by elaborating on the origin of BIM and
the multiple codes and research conducted for the creation of complete building
information modeling gives a different prospective on the matter. In addition,
the inclusion of your coop experience in relation to BIM was certainly
convincing.
Mariano A,
ReplyDeleteI found your post on BIM for architects and engineers to be an interesting read. I like how you mentioned the current debate of replacing 2D drawings with 3D models when discussing BIM. To answer the questions you posed, I think that while it is possible to replace 2D drawings with 3D models it is not the best way to approach it. I believe that the design process heavily relies on the concepts drawn on paper since it is the best way to get the creative juices flowing. However, I do think that the 3D models are there to enhance the finished concept.
