ADVANCED MEASUREMENTS FOR CONTRUCTION Done by :-S.thanusigan Qs /16 /46/30 ADVANCED MEASUREMENT FOR CONSTRUCTION Acknowledgement The writing this assignment is one of the most significant basic concept of the management subject we should understand clearly. Without the support, patience and guidance of the following people this assignment would not have been completed. It is to them that I own my deepest gratitude. Mr. N.T.K Lokuliyana who is undertook to act as my management lecturer and our English lectures help to improve my English knowledge. My friends and colleague, who inspired my final effort despite the enormous workload that we were facing together, BCAS administration, which have given us their fullest support on utilize the available resources to achieve the successful completion. My family members, who have always supported, encouraged and believed in me, in all my endeavors and given me the well-established facilities to access the all necessary information at home. Lastly, I offer my regards and blessings to all of those who supported me in any respect during the completion of the assignment. 1 ADVANCED MEASUREMENT FOR CONSTRUCTION Introduction Before getting knowledge about construction, all should understand the measurements in construction site and how to improve the taking off. This assignment helps to get a clear knowledge about construction measurements which are mainly used in most common site. There were four learning outcomes • Be able apply the measurement techniques • Be able to produce measured quantities for elements and components of large scale commercial structure • Be able to prepare preambles and preliminary items • Be able to produce measured bills of quantities To perform the assignment successfully I visited to many web sites and collected all details about materials and construction measurements. 2 ADVANCED MEASUREMENT FOR CONSTRUCTION Table of Contents Acknowledgement .................................................................................................................................. 0 Introduction ............................................................................................................................................ 2 1.1 Explain the responsibilities or the involvements of different parties in relation to the measurement work in the design, production and maintenance of a construction project. ................ 4 1.2 Assume that you are working as a quantity surveyor to contracting company.

Client The client, that is to say the party who arranges for building or civil engineering work to be carried out, has the fundamental responsibility of seeing that everyone thinks about the work environment during the different construction stages. In practice, this means that the client appoints a building work environment coordinator for planning and design and one for execution. Together with the building work environment coordinators, the client has responsibility for work environment questions being taken into consideration during the entire project. The client is responsible for: • making sure that important factors for the work environment are monitored during both the planning and design stage, and for the usage stage in the completed building • prior notification is sent to the Swedish Work Environment Authority (applies to construction sites of a certain size) • the work environment plan is drawn up before the construction site is established • building work environment coordinators, Bas-P and Bas-U • following up work environment tasks that Bas-P and Bas-U should do throughout all the stages of the construction (backup responsibility). If the developer does not make sure that there is a work environment plan when the construction site is established, they can have to pay a sanction fee. 4 ADVANCED MEASUREMENT FOR CONSTRUCTION Contractor • make sure the client is aware of the client duties under CDM 2015 before any work starts • plan, manage and monitor all work carried out by themselves and their workers, taking into account the risks to anyone who might be affected by it (including members of the public) and the measures needed to protect them • check that all workers they employ or appoint have the skills, knowledge, training and experience to carry out the work, or are in the process of obtaining them • make sure that all workers under their control have a suitable, site-specific induction, unless this has already been provided by the principal contractor • provide appropriate supervision, information and instructions to workers under their control • ensure they do not start work on site unless reasonable steps have been taken to prevent unauthorized access • ensure suitable welfare facilities are provided from the start for workers under their control, and maintain them throughout the work 5 ADVANCED MEASUREMENT FOR CONSTRUCTION 1.2 Assume that you are working as a quantity surveyor to contracting company.

This assignment more helpful for improving our knowledge & identify good materials used for construction works. This assignment work is very interesting and good experience. I hope that it will support us in the future, due to this reason I am very satisfied with this assignment and very keen to do more assignment to develop my personnel skills regarding our studies. As a student of Quantity Surveyor, I got much information through this assignment. So I hope this will help me to continue studies. 37
