The Roles And Responsibilities Of The Design Team Construction Essay
The Roles And Responsibilities Of The Design Team Construction Essay Interior Designer Interior designers are sometimes used on contracts where the internal finish and dà ©cor is important or of a prestigious nature. Some high-profile house building projects or city-centre apartment conversions have been developers in conjunction with interior designers who can add considerable value to a project. Quantity Surveyor Quantity surveyors accurately determine the amount of materials needed to build the project. They prepare a bill of quantities establishing a record of all the materials needed and identify all the information necessary to draft out a specification of the works. The quantity surveyor can then advise and guide the architect or the client on the cost of the job, check tenders and evaluate any costs as work proceeds. Landscape Architect The landscape architect is sometimes contracted to design the external environment of the project. As with interior design, the landscape can be enhanced by a specialist to improve the completed project. Resident Engineer Resident Engineers are based close to the construction works, on the construction site itself. They report back to the structural engineer and the architect on the matters relating to the structure and the load-bearing components that have been designed by the structural engineer. Structural Engineer Structural Engineers determine the design of loadbearing elements of the building and ensure that each component is designed to safely withstand the loads that are imposed on the building. Structural engineers typically work for the client but are frequently engaged by the architect to inform and supervise the design and installation of structural elements as work proceeds. They work very closely with the architectural technologist and the principal contractor. Building Services Engineer Building services engineers design and implement a range of items into the project that dont improve the resources and the quality of the building. Building services and the effective use of heat, light, acoustics and other electrical appliances have seen significant improvements in recent years and many of these items, such as lifts, escalators, air conditioning and heating and ventilation systems, need to be integrated into the contract drawings at an early stage to avoid conflicts of space or to ensure that the design can accommodate machinery, plant and equipment. Clerk of Works The clerk of works is employed directly by the client, who will want assurance that a contractor is producing a building that meets specification in terms of both materials and workmanship. The clerk of works also reports to the architect on progress of the construction works. Clerks of works do not issue instructions and do not have authority to impose variations or changes to the design but will need to inspect the works as it proceeds and hence need to visit the site frequently. On some larger sites, a clerk of works will have a resident office and spend their entire working time there. Contractor Contractors perform many duties on site and thus they are in the best position to ensure that site activities are carried out safely. Contractors must ensure that subcontractors have information about risks on the site and that all workers and operatives working on the project have adequate training and a suitable induction to site procedures. Task 3 Explain the roles and responsibilities of the production team. (Identify then describe the members of a production team, this is the team that will produce the building from the design) The Production Team Projects Manager Site Manager Quantity Surveyor Site Engineer Task 4 Describe the legal implications that could arise from miscommunication Legal implications that could arise from miscommunication include- In terms of legal position The client is put at the top of any hierarchical chain. However, the client usually tends to place the responsibilities on the architect, the design team and the contractors. To prevent any legal implications, architects are required by law to hold qualifications that show that they completely understand the principles of design and can build a sufficiently strong structure. They must also comply with the legislations such as planning, building regulations and management regulations and the disabled and disabilities act. Furthermore, architects are required to have adequate public liability insurance to protect any third parties from any defects or problems related with their work. Task 5 Changes made are window size have been increased (communicate this to the production team) Write letter to (proof and backup needed, when communication has taken place) Paragraph on the different communications Produce a written communication between design and production team- Write sample letter to product team about change in window size Tell building to leave gaps for the windows (bigger gaps) Who needs to be told? QS Because specification will change Task 6 Describe a modern method of construction look for a sustainable method employing timber or a technological product. Describe what methods and components could be used to construct each type of building- Why is there a need for these different methods and components? Merit Criteria Task 7- Obtain a copy of RIBA current plan of works, how does it work? What are its merits? The benefits of using the RIBA plan of work are that it is easily understood, it is a well-planned, coordinated structured approach. What are all the stages? How will the team members be coordinated to complete the project? RIBA Plan of works Feasibility phase- Inception Feasibility At this stage of the plan, the architect will work closely with the client to determine and prepare the requirements of the building project. Architects will provide clients with an appraisal and recommendation so that they can determine the form in which the project is to proceed, ensuring that it is feasible both in technical and financial terms. Pre-construction phase- Outline proposals Scheme design At this stage, the architect will usually have determined through sketch plans the layout, design and construction in order to obtain approval of the client on the outline proposals and accompanying report. To complete the brief and decide on particular proposals, including planning arrangements and appearance, constructional method, outline specification and cost, the architect will then draft plans and drawings for submission to the local authority to obtain all approvals such as building control and planning consent. Detail design At this stage, the architect will have to obtain final decisions on all matters related to design, specification, construction and cost. BVy creating working drawings and finalising the full designs of every part and component of the building, the architect draws together the construction team. Meetingds of the team will take place to discuss and decide materials, finishings, services, contributions by specialist firms and a range of other matters relating to the finalising of the building. It is important that any changes or modifications to the scheme are noted and accommodated so that everyone can be updated and work from the latest drawings. Changes can be accommodates at this stage, although they may result in increased costs due to the scheme being planned on an early proposal. Production information This part of the plan includes the preparation of product information used in the building, the drafting of bills of quantities, tender documents and project planning materials such as the programme of works showing duration of activities and the time taken to create the building itself. This is a very important stage in the process and particular care must be taken to ensure accuracy of the work involved in drawings and specifications so that the contractors undertaking the building work have all the necessary information to hand to complete the work to the appropriate standard. Drawings require at this stage include a location plan of where the work is found, a layout drawing of the construction site itself and a general arrangement drawing that shows the layout of the work to be done. From these drawings, a series of schedules and specifications will be drafted to provide any necessary additional information. Bills of quantity Specifications are dealt with in more detail later on, but their link with the bills of quantities is important. Bills of quantities are prepared by a quantity surveyor who reads the drawings and determines the quantities and amounts of materials needed to complete the constructions work. Any part of the building that is not yet finalised or has missing information can be allocated a provisional or prime cost so that there is an amount for the work to take place is allocated even when the actual cost or amount to do this work may be finalised some time later. If the architect has not yet appointed a construction contractor or team to complete the works onsite, discussions at this stage will begin to determine an appropriate company or contractor to appoint who is capable of undertaking the work. Tender The idea of tendering is to allow the client an opportunity to present a batch of work or a construction contract to contractors who learn about the complexity, the stages of construction, the limits and the constraints anticipated within the work so that a realistic and accurate price can be calculated by the contractors. The contractors then identify the price of the works and the client chooses the contractor best suited and able to do the work. Frequently, the cheapest tender or quote is selected as this can represent best value for the client. For some work selective tendering may take place, where a architect and quantity surveyor invite contractors that are either known to them or have an established reputation for completing work similar to the one they are working on, to tender. Again, the cheapest quote is most commonly selected in this process. Contractors may be approached so that they tender an interest in the work. Sometimes a pre-tender meeting may be held with contractors and the complexity and the details of the work can be communicated to the contractors so that the contractors, the architect and he client can satisfy themselves that they are all capable of completing the work within the appointed timescale and budget. A letter of invitation to tender can then be issued together with all relevant drawings, specifications and bills the contractors can then visit the site of works and the contractor will determine and cost the project. Tenders are returned to the architect at an agreed date and time. Initial comparison of the tenders received from different contractors takes place by the architect and sometimes this includes the client or their representative. This analysis of the tenders usually results in the lowest priced tender winning the contract and being appointed as the contractor. Construction phase- Project planning This is where the work to produce the building starts on the building itself. Contract documents are prepared and signed. At a project planning meeting, the architect will usually clarify any points undecided at this stage and agree anyfurther contractual points. Contractors draft a programme of works that illustrates the milestones and the total duration of the work. Key milestones include taking possession of the site, dates of the project progress meeting and other key dates that are achieved during the lifetime of the contract. The contractor is expected to sign the contract documents at this stage, which include: A copy of the contract A full set of construction drawings Bills of quantities Specifications A register of drawings Site diary and associated report forms Site operations The site is officially handed over to the contractor who can begin construction-related operations. The site is now the responsibility of the contractor who has to comply with all the legislative requirements and legal constraints. The contractor should be informed of any rights of way, preservation orders, protection requirements and any other environmental issues that need to be considered in terms of the work and the activities on site in the months ahead. the contractor has a duty to ensure the appropriate site supervision of all those involved in activities onsite. a clerk of works will check on behalf of the client and the architect that the contractor is complying and building the project to the appropriate standards of materials and workmanship. samples are taken of various materials, sometimes by a specific request from the architect and other times by established practice in some cases, such as the sampling of concrete which is regularly tested by way of a slump test to ensure workability when it arrives on site, and its strength assessed by testing to destruction samples at regular intervals after the concrete has been placed. brickwork panels are sometimes erected to enable the architect and the client to see what the brickwork will eventually look like. tiles, blocks, panels, etc. may also be subject to a request that the contractor builds a mock-up or sample panel for viewing by the architect and the client so that the quality and the desired finish of the work can be ascertained and ensured. The contractors duties at this stage of the plan are to work diligently on the construction works adhering to all relevant health, safety and welfare legislation. the contractor is also expected to maintain a site diary to record relevant information about the progress of the construction works. typically, a site diary will include information on: weather conditions visitors on site for the period any deliveries of materials to site progress of work to date personnel onsite including subcontractors any comments and notes taken about the work undertaken Discrepancies and any inconsistencies in contract documents. Completion as the building starts to take shape, the contractor may be required to hand over part of the building to the client. the actual date of handover is planned and any outstanding issues relating to the construction works can be determined and a solution found. the period of notice required varies from site to site, but usually adequate notice is required in order to prepare the area and any other supporting documentation. the client should be in a position to accept the building for its proper use so the architect will usually insist on inspecting the area and determining for themselves that the work is to the appropriate standard of materials and workmanship, that all services and equipment are functioning appropriately and effectively and that the as-built record drawings are a true record of the actual building. the building manual which in the case of a simple domestic dwelling or house will be simple could extend to a complex and detailed manual of several volumes for an industrial or more intricate commercial building. a certificate of practical completion can be issued by the architect to the contractor which then enables the contractor to claim monies due for the construction work and address any defects and snags that have arisen so far. at this stage, the contractor has effectively completed the construction stage and has no responsibilities for the insurance of the building or its works. When all defects or amendments or outstanding issues are addressed, the architect will issue a final certificate and the account will be adjusted for variations, subsequent instructions and fluctuations in labour and materials prices and/or costs Feedback the final part of the riba plan is to analyse and evaluate the progress of what was expected with what was actually delivered. architects will need to determine what has happened in order to achieve better performance in the future. typically, an analysis and evaluation could include the following: what does the client think of the completed building? Does the building function effectively? What parts of the design were particularly successful or problematic? Could this design process have been undertaken differently and have provided a better service to the contractor or the client? What relationship and communication existed between the design team and the construction team? How could these be improved in the future? Did the contractor meet all the performance targets in a timely and effective manner? Did the design process run smoothly? If not, why? Was the job profitable and was the contract fulfilled? Why will my company use RIBA and what happens if it is altered or not adhered to. Why the company will use RIBA The riba plan is usually accepted as the most suitable plan, although many other types of plan are acceptable for smaller building projects or for instances where the riba plan may be too inflexible when conditions change frequently. The RIBA plan of work is known for being well planned, coordinated, and known for having a structured approach. Task 8- Compare the methods available for communication, for example, advantages and disadvantages of each. Explain why the contractor must implement these changes Distinction Criteria Task 9 Analyse and discuss in detail the RIBA plan of work in terms of handling a design change after work has started. Evaluate the effectiveness of the plan from design to construction phase and provide examples of the plans flexibility to resolve changes of design quickly. Include how these changes are quantified.

The Language Of The Cell :: essays research papers
The Language of The Cell à à à à à The cell is a complex and delicate system: It can be seen that the cell is the stage where everyday functions such as molecule movement, protein synthesis and tissue repair take place. All organelles within the cell are well rehearsed in their operations, but an error on an organelles behalf, can send the cell and itââ¬â¢s organelles into panic. The efficiency rate of the cell plummets down to a low level. It does take some time for the dust to settle, and once the scripts are memorized, the cell is now ready to begin itââ¬â¢s tasks again. à à à à à Since the 19th Century, it was known that all living things, whether they were plants or animals, were made up of cells. This whole idea has been given credit to an English Physicist, Robert Hook (1635-1703), when he looked at a thin slice of cork under powerful hand lens. Hook discovered a large number of cells. Rudolf Virchow (1821-1902) propounded this idea, that the cell is a basic structure and functional unit for all living organisms. à à à à à A cell can be a wide range of shapes and sizes, although most cells are microscopic. Inside a cell membrane, a nucleus can be seen. The nucleus is the control center of the cell. Between the nucleus and the membrane, there is a polysaccharide matrix called the cytoplasm, where organelles can be found. The organelles are attached to a framework. The cellââ¬â¢s cytoskeleton. à à à à à Every living cell has the ability to detect signals from itââ¬â¢s environment. The signals are usually in the form of chemical molecules, that the cell has learned to recognize. The cell decodes these molecules into messages, and acts upon them. The cell has a ââ¬Å"languageâ⬠. Signals and messages are carried by particles of matter that have a very low energy requirements. There are many, many signals rumbling around the cell. It was thought that the cell would confuse itself in all of that background signal noise. One defense is available to this question. The cellââ¬â¢s decoding mechanisms are located downstream from the receptors. They are based on complex chemical reactions that take place in the cell membrane and control all the responses of the cell to the messages it receives. à à à à à Neuropeptides and polypeptide hormones, are made up of complex assemblies of amino acids, aligned in different sequences. In other cases, the amino acids are slightly transformed, as this is the case with well known transmitter substances such as epinephrine (adrenaline), dopamine and histamine. à à à à à Products made in the organelles within the cell, are sent to various destinations, both in and out of the cell. The cell has what amounts to a

Petitions of African Chiefs Essay
1. When the slave trade was abolished in certain regions of Africa, the Africans were forced to find other alternative sources of livelihood such as entering in a legitimate trade of shipping various products.à à à Instead of selling human beings as merchandise, the Africans accepted the timber trade when it was introduced by the Europeans.à However, whenà the timber trade did not succeed, they turned to growing and exporting ground nuts and when this too did not come through, the Africans resorted to palm oil trading ââ¬â the subject of King Ockiyaââ¬â¢s letter to the Earl of Derby. 2. Since the abolition of the African slave trade, Africans having been trying to find other sources of income and livelihood.à Among such is the valued palm oil which they collected from the hinterlands.à However, greedy British traders wanted to bypass them and go directly to the source of these valued commodity.à Hence, the African leaders were asking the British to let them have their own source of livelihood, free of intervention from the Europeans who were already encroaching on their trading posts thereby stopping the African trade completely. The petitions and demands of the African leaders show how powerful the Europeans are that even building huts or places of abode are considered taxable.à Nonetheless, these ruthlessness of the Europeans paved the way for the Africans to wake up and saw all of these as an assault to their customs, livelihood and traditions. Linââ¬â¢s Letter to Queen Victoria 1. The rise of the opium trade in China according to Lin has poisoned and injured its people.à The laws of the country have been disregard in lieu of the temptations and addiction of the opium drug. 1. Lin tries to convince Queen Victoria to stop the opium trade by appealing to their conscience and strict morality. He tries to emphasize that since opium is forbidden in Britain and brings harm to the British people, the Queen must condemn it as well especially its importation.à As Lin proudly said, China has only exported things that are beneficial to the people and opium is not one of them. By giving the impression that China only exports things that are beneficial, from which the world has undoubtedly benefited, Lin thinks that Queen Victoria and the rest of Britain might be convinced of his argument.à However, the tone of Linââ¬â¢s letter is also threatening whereby he gives the appearance that China in consonance with its laws will not hesitate to execute anyone caught selling and using the prohibited drug. Hence, the response of the British will naturally be to disregard Lin and his contention, even get angry at such preposterousness.
