Dear Colleagues:
 Welcome to the e-conference for Discussion on New BIS document SSD-II 06 (19914) : REQUIREMENTS FOR STRUCTURAL DESIGN AND PROOF CHECKING CONSULTANCY SERVICES FOR STRUCTURES.
 The topic of this thread is Review of Existing Practices.


Currently, we have different models of appointment of Principal Design Consultant (PDC) and different categories of proof checking based on their level of independence. Under this topic/thread, we would deliberate on the advantages/disadvantages of these models as well as the way forward in retaining some of these existing practices.  
I will be moderating the discussions of this topic/thread. I request you to send/post inputs as close as possible to the topic/thread. This will help in the final compilation and consolidation of the discussions. 
 Thank you, and looking for a spirited and effective e-conference.

Existing Practices :
PDC - Prime design Consultant
PC- Proof Consultant

1.0 In absence of this much awaited code , existing practices are only for some high value projects like Bridges   , Flyovers , and some other important projects of Govt.

Review needed : All Structural works needs to be covered under PDC + PC  with exception that  small works can be under PDC only (pC  can be skipped)( See prev posts from my end on Applicability of code)

2,0 Model 1 : Existing practice is that owner appoints proof Consultant and Const Agency appoints Their  PDC. It is prevailing in  Turn key Projects.


Review needed :  It is OK , no need to change

3.0 Model 2 : Owner appoints PDC  , but do not appoint any external PC . Owner having its own design deptt act as PC. It saves extra cost to Owner.

Review needed : expertise of special structures may not be available with Owner design Department  acting as PC , and Review becomes eyewash. Hence if Owner wants to act as PC , it may be discouraged and external PC be appointed .

4.0 Model 3.0 :  Owner with its in house  design deptt act as PDC ,but no  PC  is done . This happens in some Govt and mega Construction  Agencies.

Review Needed : Owner design Deptt can act as PDC as talent is available everywhere. But It must be vetted by third Party PC .

5.0 Model 4.0  Same as Above 4.0 but Owner sends it design to Engg institute for vetting , some Professor  vett it.

Review needed :  It is OK,  if it satisfies , but Institute vetting be on some selected works

Firstly, I could not understand the reason for calling Structural Designer as “Principal Design Consultant(PDC)” as it gives the meaning of “Comprehensive Design consultant”, where the organization holds the responsibility to deliver design covering all Disciplines
Calling Structural Design Consultant(SDC) or Lead/ Principal Structural Design Consultant would be appropriate

What is the role/responsibility expected from Principal Design consultant in UK regulations are very different.(Refer attachment)

In my view, currently no such regulations are present in India. Establishing this may be necessary.
