I am deeply grateful to the GOA FSAI Chapter for the opportunity to share my expertise on Fire Protection system... Tender Drawings, Specifications, BOQs, and Pump Calculations. It was a privilege to discuss these critical elements that are essential for ensuring effective fire safety systems. During the presentation, we explored: 1. Tender Drawings: The importance of accurately detailed tender drawings, including Schematics, layout plans, sectional views, and isometric drawings, which provide a clear and comprehensive visualization of the fire protection system. Emphasis was placed on ensuring that drawings adhere to the relevant standards and codes, such as NBC,IS,NFPA,FM,OISD and local Goa regulations. 2. Specifications: The role of precise specifications in defining the materials, components, and installation methods required for the fire protection system. We discussed the necessity of detailed technical specifications to prevent ambiguities and ensure that contractors deliver the expected quality and performance. 3. Bills of Quantities (BOQs): The preparation of detailed BOQs that list all the components and quantities required for the project. We highlighted the importance of accuracy in BOQ preparation to facilitate transparent and competitive tendering, accurate cost estimation, and effective project management. 4. Pump Calculations: An in-depth analysis of fire pump calculations, including determining the required pump capacity, pressure requirements, and selection of appropriate pump types. We covered the methodologies for calculating the hydraulic demand of the system, considering factors such as friction losses, elevation changes, and flow rates. The discussion emphasized the technical precision and meticulous planning necessary to design and implement reliable and compliant fire protection systems. I look forward to furthering our collective knowledge and practices in fire safety engineering through continued collaboration and knowledge exchange.

During Project execution, the Designers need to have discussions with Project Team to arrive at a decision on the spot. Several site considerations force us to be alert to various factors and consequences under a tight time constraint. Many of these decisions have major impacts on project timeline and cost, so it is important to have the critical awareness and thinking skills needed to make such decisions when they are required.

Erection : Unlike in middle east, we in india engaze erection contractors to erect as per design package. In middle east, the design engineers don't have to bother about erection work order but in India we have to. Brief activities in erection are :- 1. Installation of equipments 2. Power, control lighting, earthing( Optional) Cable Laying 3. Cable Termination 4. Earth flat laying and termination 5. Excavation if required 6. Civil works for above Everything above needs to be quantified. The plant Bill of Material to be included in above work sheet or scope of work with clear list of free supplied items on the basis of which erection contractors are asked to quote . The Scope of Work must address what work the contractor should do. Ideally, the contractor should supply erection tools and hardwares to do the job and erect all free supplied items.At least I used to do like that. The above scope of work is made part of order and used to monitor daily work progress and contractor invoice for payment. Variations are adjusted through unit rates It takes an expert to carefully write that scope of work. For good ten odd years I used to do this in Nicco Projects kolkata and never let contractor cut loose. Except big EPC houses, small EPCs does not have own construction team and offload erection work outside. Some Clients do not want to go EPC , instead they get the erection done by erection contractor as per design done by design contractor. .

Structural engineers. Recent failure of the statue of Chatrapati Shivaji a nd consequent arrest of the structural engineer made an interesting reading. How was he singled out for this punishment? Did they analyse the roles of different agencies in the failure? No . Nobody involved the structural engineers in any major or medium scale structures like multistorey buildings palatial houses , or where foundation gives technical problems. But, where he is involved they are prompt in punishing him. The services of an experienced structural engineer in any big project especially infrastructure projects need not be emphasized. But it is unfortunate that they are not consulted in such projects. The recent failures of around ten road bridges in Bihar are examples. Many managers do not know or do not care to know the difference between any experienced civil engineer and experienced structural design engineer. The Personnel department also do not know the difference With the result experienced civil engineers are recruited where the requirement was for structural design engineers. While the undersigned was working in a few EPC and consultancy firms , they recruited wrong persons ignoring his advice. The terminology is also a bit confusing as in western nations they are called structural engineers while in India they are known as structural design engineers. This should be taken by the institutional bodies like Institute of Structural engineers, etc with the goverment agencies , consultancy firms like FPDIL , private consultancy firms like SaiPem Linde , Aker Solutions , Reliance, Essar group ,Technimont ,Toyo ,Hitachi Zosen , UHDE , HDO etc. A panel of experienced structural design engineers be prepared , if necessary , by including the superannuated persons also and their comprehensive services and advices are to be taken seriously by the project managers.

#artofprocurement: How Civil Contractors are Classified In the Public Health Engineering Department (PHED) , civil contractors are typically classified into categories like AA, A, B, C, and D, based on various criteria. These classifications are used to determine the eligibility of contractors for different types and sizes of public works projects. Factors: 1 Financial Capacity Contractors in higher classes (e.g., AA and A) must demonstrate higher financial stability and capacity. This includes minimum annual turnover, working capital, and solvency requirements, allowing them to handle larger and more complex projects. 2 Experience and Expertise Higher-class contractors are expected to have more extensive experience in similar projects, demonstrating proficiency in completing works of similar nature, complexity, and scale. They may need to show a history of completed projects with budgets exceeding a certain threshold. 3 Technical Capability and Equipment Contractors are classified based on their possession of requisite machinery, equipment, and technical manpower. Higher-class contractors are required to own or have access to sophisticated equipment and a skilled workforce for advanced project execution. 4 Performance Record Contractors’ previous performance, including project completion timelines, quality standards, and adherence to safety regulations, is also taken into account for higher classifications. 5 Registration and Documentation Compliance Each class requires specific documentation, including registration with the department, bank guarantees, and completion certificates for prior works. Higher classes require comprehensive documentation to verify compliance. General Classification Overview 1 Class AA: Eligible for the largest and most complex projects. These contractors have the highest financial and technical qualifications. 2 Class A: Qualified for significant projects but slightly smaller in scale than AA-class projects. They meet substantial financial and technical criteria. 3 Class B: Eligible for medium-sized projects, meeting moderate financial and experience requirements. 4 Class C: Suitable for smaller public works, with limited financial and technical capabilities. Class D: Limited to small-scale, local projects with basic financial and technical qualifications. Typical Use of Classifications Each class limits contractors to projects of a certain budget range, ensuring that contractors are assigned projects that match their capacity and expertise. This classification helps PHED in Rajasthan manage project quality, control risk, and ensure that public works are handled by capable contractors. To gain or maintain a particular classification, contractors often undergo periodic evaluations and must renew their registrations to continue bidding in their assigned categories.

An unfortunate accident happened at Delhi Airport. Most of us are trying to put the blame - some on political parties, some on the infrastructure company and others on the contractor. But no one is talking about the engineer who was involved in the construction! Structural integrity of any structure is the responsibility of the engineer. Why did that person not take it into account? Let's ask ourselves, which branch of engineering is the least preferred by JEE aspirants? The branch which used to be quite sought after a few decades earlier is now the last preference. Yes it is Civil engineering! What could be the reasons for this apathy? Long standing hours, dusty workplace and such make it at par with a blue collar job. Then the expectation of sitting on a chair in the AC field office. Do you still feel that the Political parties or contractor are responsible?
