Ar­chi­tects and En­gi­neers across the world are in­creas­ingly us­ing tech­nol­ogy to make their lives sim­pler and work faster. One such in­no­va­tion that has changed the way construction sec­tor func­tions is Build­ing In­for­ma­tion Model­ing (BIM). It has be­come an es­sen­tial part of any project de­sign to­day. It en­ables smarter and faster de­sign process, in­tri­cate plan­ning and vi­su­al­i­sa­tion, to sim­u­la­tion and construction. This soft­ware helps teams to col­lab­o­rate, in­no­vate, and con­nect with clients in more pro­duc­tive ways than ever be­fore.

One of the most widely used BIM soft­ware is Au­todesk Re­vit. The ease of making changes in­spired the name Re­vit, an ab­bre­vi­a­tion of Re­vise-It. It al­lows users to de­sign a build­ing and struc­ture and its com­po­nents in 3D, an­no­tate the model with 2D draft­ing el­e­ments, and ac­cess build­ing statis­tics from the build­ing model’s data­base. Re­vit is 4D BIM equipped with tools to plan and track var­i­ous phases in the build­ing’s mat­u­ra­tion, from con­cept to construction and later main­te­nance and as­set man­age­ment.

In­dia is one of the fastest grow­ing construction mar­kets in the world, grow­ing at 7-8% ev­ery year. Es­ti­mates sug­gest that In­dia’s construction mar­ket will be the third largest in the world, with a size of $1 tril­lion by 2025.

A Ti­met­ric Construction In­tel­li­gence Cen­ter (CIC) sur­vey which sur­veyed 100 global construction in­dus­try agents found that the ma­jor­ity of re­spon­dents be­lieve BIM is the fu­ture with 49% al­ready us­ing it. Also, 50% of re­spon­dents be­lieve cost sav­ings and op­er­a­tional ef­fi­ciency are the ma­jor driv­ers that af­fect an or­ga­ni­za­tion’s res­o­lu­tion to im­ple­ment BIM.

The Re­vit BIM soft­ware has a num­ber of ben­e­fits which the com­pany can make use of. It pro­vides a de­tailed 3D vi­su­al­i­sa­tion of draw­ings, making the model­ing easy which can save a lot of time.

There is a bet­ter co­or­di­na­tion be­tween dif­fer­ent de­part­ments be­fore im­ple­men­ta­tion of the model, which helps in meet­ing the project dead­lines.

Re­vit also pro­vides ef­fi­cient and fast doc­u­men­ta­tion tools. It helps in sus­tain­able build­ing de­sign which is vi­tal in the mod­ern world where peo­ple are much more aware of the ef­fects of their build­ings on the en­vi­ron­ment. It fea­tures sev­eral an­a­lyti- cal tools, which can be used to mea­sure the en­vi­ron­men­tal im­pact of construction mod­els.

In­dia’s construction sec­tor has sev­eral chal­lenges. There are no stan­dards in the in­dus­try and there is a de­fi­ciency of project man­age­ment ex­per­tise, which re­sults in project de­lays and cost over runs. The soft­ware used are ex­pen­sive and re­quire ad­vanced hard­ware.

In­dian BIM As­so­ci­a­tion has steered a widespread sur­vey to un­der­stand the road blocks for BIM im­ple­men­ta­tion in the mar­ket to re­al­ize the hur­dles that the In­dian Ar­chi­tec­ture, En­gi­neer­ing, Construction and Op­er­a­tion (AECO) in­dus­try stake­hold­ers are fac­ing for dif­fus­ing BIM tech­nolo­gies and work­flow sin A ECO projects.

Some­times, even those who want to em­brace BIM-friendly pro­cesses can’t, be­cause of com­pany poli­cies. Le­gal de­part­ments are a com­mon hin­drance when it comes to adopt­ing in­no­va­tive mea­sures. The lack of avail­abil­ity of spe­cial­ist con­sul­tants who are will­ing to use BIM has also made its im­ple­men­ta­tion chal­leng­ing in In­dia.

Most of the de­sign firms as­sume that pro­duc­tiv­ity loss dur­ing the train­ing pe­riod of work­forces would be un­re­cov­er­able. This is part of the larger prob­lem of short­age of trained pro­fes­sion­als in the real es­tate and construction sec­tor. As pro­fes­sion­als, all of us are aware of the ad­van­tages of adapt­ing a BI M cen­tric de­sign de­vel­op­ment. How­ever there are too many hur­dles as on to­day to im­ple­ment it due to var­i­ous com­mer­cial and prac­ti­cal chal­lenges.

The need of the hour is to use it ef­fec­tively in a few large-scale land­mark projects and make it a bench­mark for BIM prac­tice for fu­ture Projects. In this en­deav- our the Prin­ci­pal Ar­chi­tec­tural firms have a large role to play. They have to cre­ate in house BI M spe­cial­ists which is in­te­grated in their de­sign de­liv­er­able SOPs. Ap­point­ing a third party BIM agency, which is the norm to­day, is not able to har­ness the max­i­mum po­ten­tial of a BIM driven pre­con­struc­tion process.

As per a re­search re­port, in­ter­na­tional BIM mar­ket — with the Asia-Pa­cific re­gion show­ing the most growth — should hit $11.7 billion by 2022, grow­ing 21.6% be­tween 2016 and 2022. It’s a promis­ing fu­ture wherein build­ings, de­sign and construction will be cheaper, safer, more ef­fi­cient, and more re­spon­sive to end-users.

The world’s sec­ond tallest build­ing, Shang­hai Tower in China, was pos­si­ble mainly due to the ap­pli­ca­tion of BIM tech­nol­ogy. The Shang­hai Tower de­sign­ers re­quired the im­ple­men­ta­tion of a BIM process us­ing Au­todesk BIM so­lu­tions for the de­sign and construction of the tower, to meet the am­bi­tious goals set for the build­ing. BIM helped their team pro­duce a high-qual­ity project and evade many on-site changes, which would waste time and re­sources.

The present sit­u­a­tion is not so favourable for BIM adop­tion in In­dia, how­ever, with time, things will cer­tainly look up. The ben­e­fits of im­ple­ment­ing BIM in construction can­not be de­nied with the grow­ing trend of cloud-BIM in­te­gra­tion, which fur­ther en­hances co­or­di­na­tion and sched­ul­ing of projects. As the tech­nol­ogy ma­tures and be­comes more ad­vanced, the PMCs in In­dia need to en­sure that they de­liver such in­tel­li­gent piece of work.
