analytical case study on a typical construction project Architectural Design Concept update at the practical application / strong> Introduction The project is an extension to an international institution, funded by a foreign body in the institution. The project is almost completed and it is in the phase of the warranty period. The project has a number of problems have been encountered, from the beginning to the end. Therefore, it is a project that deserves to be examined by a ruse. be The problems are found in places where they are self-described discuss, under a sub-theme that the observations and conclusions of the author, rather than go to a discussion of issues important at the end of this document. phase of a pre-contract – Pre Design Stage Line Out and design proposals < / strong> 1 The First First Scope the project is a renovation of an existing building in an international institution Narahenpita. The scope includes the design and construction of the extension of existing building and grinding and painting the existing building. The new building consisted of approximately 6,000 sqm and is almost equal to the size of the existing building. The estimated cost of the project is twenty-five million rupees. The existing building is also the same organization (Consultant) 25 years ago. First The second letter to the client and the project approval process The client is an independent management and accounting and Narahenpita the organization’s headquarters is based in London. The customers consisted of a brief addition of a field study, administrative office area and an auditorium, the existing building. Access is the existing building to the new provider. The design of safety standards in Britain are implemented. The client is an international consultant and local consultant projects must go through international consultants and the client, based in London and the agreement will be made to be preserved. First 3e> Location and site The site is Narahenpita and is adjacent to the existing building client. The country is a country whose government is one of the Players Association carom. The country has been maintained for twenty-five LEAs by the client for the creation of the new building. 2nd AACC Consultants 2nd First Consultancy firms and other consultants < ; / p> The project has a history, beginning with an international consultant who has worked as chief designer of the project. The design has been completed and after the terms of the contract FIDICT because, as always recommended by international consultants, the tenders will be called. The tender figures were extremely high and the project was not feasible. The project must be rethought. The local consultant has been appointed as the principal designer of the international consultant has been appointed as an organization to examine the design and supply. The contract was agreed to be subject to the terms of the contract ICTAD. The design has been developed by local consultants. Design Consortium Archedium LD and was the principal adviser to the design and organization named the possibility of all the services that the consortium may be structural, electrical, mechanical and surveying services include quantity. The design team appointed including a structural engineer, mechanical engineer and electrical and one scorekeeper. However, the Fire Department has been appointed to provide consultancy for the design of fire alarm and detection system. Consultant informed in writing of the fire department that they are the project consultants, and they expect advice from the fire department to learn the fire alarm and detection system project design. (Supplement 01) The consultant had the ability and experience of the fire alarm and detection systems design for themselves. But since the concerns of customers with greater fire safety and standards system, it was decided to go to a consultant. With the approval of the fire department, they can provide the services required for applications for the client organization by writing to the Fire Department to provide the cost of supplying their services. Bids received were forwarded consultant consulting and confirmed in writing that the offer is reasonable and acceptable. was The contract with the Fire Department formed a direct contract between the client and fire departments and there is no contractual obligation with the consultant. Under the commitment is the term for this situation – The architect is entitled to hire other consultants and is liable to the customer for their services. Where others to advise clients and the architect is only responsible for the coordination and integration of their services. Consultant has seen only approved estimate for the fire department and no added overhead provided. The fire department is only recommended by the Consultant and Consultant, or its services sector. There is no contract with the consultant trained, but there is a contract with the client. Therefore, there is no contractual liability consulting and protection against fire detection system of the building. of professional fees The costs were calculated according to the recommendations of the AFF. The payments are in various stages Sketch Design 2 Schematic 3 folder 4 Offers 5 Inspection and > 3rd 3rd First> Creation Some of the existing building is constructed on a raft and the other half on stilts. The reason for this design, the different state of the earth. The depth of the bedrock on one side of the building is low as is economically built on stilts. On the other side of the building, the bed was rock than 28 m deep, it is more economical to build a raft. The new building will be constructed adjacent to the existing building and are then connected together at each level. But the foundations of the existing building is recommended to keep quiet. Crack formations are observed in the existing building and therefore the risk in the design of the new extension has been implicated high. With the new building, the existing structure can not be bothered. The consultant decided and informed the client, the two-phase project to do. In the first phase, the most – which is the construction of new building – has been completed and the second step, changes in existing buildings will be made. The new building will be built entirely on the end of concrete piles Baring. Observations and conclusions of the author The recommendation for the type of foundation was given by business consultant investigated soil and therefore reduces the consultant responsible or partially transferred to another organization. However, special attention should be paid before construction, documentat and photograph the existing cracks. The decision of the consultant to the changes in the existing building to do – which includes repair of existing cracks – after the new building is safer decision on the part of consultants. Any impact on the existing cracks in the old building through the construction of new building to create activities, vibration, such as nesting stack and includes dynamic load test piles should be clearly visible. If she can not distinguish the correction of crack front and is grounds for rehabilitation of cracks, whether a defect in the repair or if there is an effect of the new construction. Under the contract, the contractor all the cracks that appear in photographs in the existing building, and then they are signed by the client and consultant documentat. Therefore, it was not necessary for the consultant to a separate registration cracks for his justification to do. But in a situation where these records are not included in the scope of the contactor, the counselor should investigate the cracks have to do it myself. <; / P> 1st 2nd 3rd “A rel =” nofollow “onclick =” javascript: pageTracker. _trackPageview (‘/ Outgoing / article_exit_link’); “href =” http://www.

The proposal was sent to clients based in London for their comments. The project design has been accepted by the customer organization with comments. The design is revised to meet British safety standards. The proposed revision was presented to the client with a project plan to tender. 2nd phase of the contract pre Two – Design and development of 1st 2nd Design Development < ; / strong> 2nd 1st 1st site analysis and initial proposals The site is an occupied country, initially conceived as swamp. Therefore, the ability of Baring poor soil. A soil test was conducted and identified the location of the bed between 18 different rocks up to 20m. Illustrations advising clients head office in London, and his advisors for their opinion. There were complaints that the drawings on the limits of the cost of the customer must be revised. and the conclusions of the author A comprehensive analysis of the site has not been done before the draft proposals. The project is a good example to show how a project can suffer if the designer does not consider light the need for an analysis of the appropriate location. The issues are things later identified below, which, if bigining noted that many problems that have occurred have been avoided given. (The issues are joined by some of them ware otherwise specified in this document) 1, there were data lines, electrical cables and storm water flows through the site. 2 identified a public sewer crosses. 3 reasons access to the site does not have public sewer. The drains that are along the Elvitigala Mawatha and next available slot, the storm water has been released could be found 300 meters from the site. building was designed so that water from the tap, it is coupled with the existing system. After building the system, it was found that the current system of direct discharge of stormwater and illegal on the street. No cost solution to this problem could be proposed. And the problem persists. Was he once said, the problems would be designing a system where the storm water harvesting or is directed, a soakage pit system studied have been avoided. 2 1 2 Diagram of the structure and regulatory approvals the schematic design is completed and approval has been received by the client. Before the approval of the CMC, the clearance of the planning done by the UDA. In preparation for this application certificates of Ceylon Electricity Board, water and drainage certificates should be obtained from the competent authorities. If it is used for clearing of drainage, CMC informed the position of a sewer line 9 “on the page at a depth of 12 ‘. 5 ‘minimum distance from the sewer line and construction and nothing can be considered as being built on the line of drains. (Supplement 09) If the line had remained intact, the design must be changed. The design has also been assumed that the sewer could be diverted, but if it was discussed with the authorities of the Ministry of Municipal Engineers, Water Supply and Drainage Division – Maligakanda was found that the diversion of track accordingly costly and time consuming. According to the design was revised to obtain the required distance from the sewer line. After receiving the preliminary approval of the UDA, the design has been submitted to the CMC. The building is an extension of an existing building, and, therefore, approval of an extension and will not be won as a new building. However, the old part of the building on the land belongs to the client and the new building is located on land owned by the government. The expansion can not occur if countries are grouped. A merger plan has been made by a surveyor. And the plan was presented to keep documentary evidence of the lease. The situation was discussed with the Division of City Planning, was Municipal Engineers Department, CMC, and has approved the merger. to enable The development of the CMC was obtained in August 2003 and it is good before the final award. and the conclusions of the author The consultant has not LEA considers the country before being appointed. If the incumbent was appointed earlier and the site was under investigation, identification of the public sewer would be an important point that would have on the value of land and hold the lease could be brought back value . stat is above all the design work, planning permission has been obtained. The consultant had to leave the scale of the schematic structure before obtaining CSF and following the design everything changed. The time and cost-sharing had to be removed by the consultant. / strong> The file The consultant suggested that a firm offer to go. The type of contract is the name of a degree and nature of pay fixed rate contract. The conditions of the tender and contract terms are derived ICTAD terms of the contract. The consultant first proposal of two bids and the project website has been programmed to make an offer to stack and another for construction. But finally it was decided that the offer. and the conclusions of the author There are advantages to break the tender in two parts. It should be noted that the proposed contract did not have the capacity of the battery, take out the works. It accumulates in every case a sub-contract. By separating the two, may be borne by the prime contractor will be saved. The civil contract will begin at the end of the accumulation and therefore it is not necessary to pay a participation fee. There will be significant savings. Preparation of tender documents for the civil contract that can be done by piling is in progress and before the accumulation of the tender can be granted. It will be a significant time saving and. The disadvantage is that the two bids is the responsibility of the structure are then divided between the two organizations in the event of failure or damage to the structure or for any damages or settlement of an adjacent building It is difficult to identify the standard games. The responsibility for the accuracy of the clusters by showing an additional responsibility for the consultant. The insurance piling contractor has not only the construction of batteries, but the construction period, more than a year. The large insurance costs are ultimately born by customers. If the total cost of insurance will be considered – the contract amount of hype and civil contract – insurance costs are lower to go to a single contract. The old building is adjacent to the place he came to cracking and therefore there is a risk that this building can be damaged by vibration and loading on the site. Therefore, the decision on the tender distinguishes clearly the responsibility of the contactor. The consultant has a list of bidders short list for the client, which included four issues of the bidder. The client list tendereds approved a proposal to add two other bidders in the list. The consultant then sent the tender documents for the client for their comments. Client provided their comments in the form of a report. There were two critical remarks made by the client, the agreement of non-consultant. The client proposed, it is possible to make the contractors pay VAT, instead of the client. The client proposed, it is possible to request a price breakdown of how the costs of materials, labor and overhead costs are included. The consultant said that it was imposed on the owner of responsibility for any subsequent increase of the tax by the government, and therefore can not be transferred to the contractor. In addition, the consultant said that if bidders were invited to submit their offers in detail to the point, nobody is interested in participating in this tender. Tenders The letter asked for the interest in the invitation to participate was sent to all bidders proposed, and both bidders have said they are not interested in participating in the tender. As the number of bidders is not enough, two new names have been proposed. agent collected the tender documents. The pre-bid meeting took place on the ground. And the questions raised and the clarifications by tenderers registered and newspapers are copied to all bidders. Bidders were able to send their careers for consultants and questions from all bidders responded and treated in all copies. The bids were submitted to the consultancy. The bids were received and opened with the presence of the client, consultant and project manager of the consultant Quantity Surveyor. It is important that the letter was sent to research participation in employment and confirmation of bidders before the tender ontained. If the alert is sent indicating the availability of bidding documents and the time there were problems to be encountered when involved large numbers of bidders, because the dates are fixed, there would be no identify sufficient time for bidders to fill this gap. Tender Evaluation p will be assessed if they completed correctly and arithmetic errors. The tender was evaluated on the corrected figures do not seem tender. aspects of decommissioning have also been considered. Cost Plan Work histogram All figures of supply be too high for the budget clients. Budget customers was twenty million rupees and the bids received from figures of 35 million rupees sixty million rupees varies. The reason for the higher bid values can be done through the introduction of higher security standards, conditions and restrictions by the customer. Of all the bidders, two competing bidders have been selected according to criteria above. The tender documents, negotiations with both bidders place. In the negotiations on three things were a saw to cut construction costs. possibility of the bidders to lower prices, which are questionable, consultants and thought to contain too high If

where the specifications of the high prices consultant to verify the opportunity to change the specifications and lower prices instead on certain points of the main contract to remove and preserve the possibility of the appointment by the subcontractor to a lower interest rate. It was noted that this exercise is not enough to reduce construction costs to a level acceptable to the customer. Therefore, it was decided that some elements of the contract such as construction of water marsh, water reservoir, etc. The money for the construction of these must be removed for the amount of money to be released from inside the building by the clients are obtained, based in London. New prices of the two bidders are compared and from which a bidder has been chosen to award the contract. Contracts consultants recommendation has been sent to the client with the comparison of the two bidders. The recommendation was accepted by the customer and the award letter has been sent to the tendrderer selected. The contractor has mobilized to start with the letter of award as a legal document, work, and the contract will be signed then. Post Contract Phase One – Contract Administration surveillance> Monitoring and < ; quality control / strong> Contrary to the resident engineer, was the work quality and accuracy by the Contractor shall ensure method statements prior Submit poles equipment and the work commences. For example, statements of the procedure, the contractor has asked for the pile test batch hacking, waterproofing and termite control. To control the quality of construction, the contractor had the tests as specified in the documentation tasks bidding. concrete cubes of concrete piles were sent to the laboratory and the results obtained by the contractor. The test results of concrete piles were considered unsatisfactory according to the consulting engineer. However, the contractor is not in agreement with the observations of consultants. Therefore, an independent analysis of the pile concrete was obtained from a relevant teacher at the University of Moratuwa. The report stresses that the quality of concrete enough to bare the burden of the construction. Following the report of independent review, issues not considered battery failed. There is no need to make additional posts. But the consulting engineer has provided instructions to strengthen the link bar on the pile foundation. The instructions were in accordance with the recommendations of independent analysts. identify on the moisture content of wood, and experiments on the nature of the wood should be undertaken by the contractor. A sample presentation of the list is included in the contract. The Contractor shall submit a sample program statement presenting its construction program. According to the submission of the sample program, the contractor must provide samples. approved samples will be attached to a board of directors and must be displayed on the site. waste of material and time will be minimized by the control system samples before the construction of them. For example, the sample was placed under the door and refused to be resubmitted to the required size, weight, degree of processing and material. (Contractor) Contractors invited to submit its work program was before the work begins. The program has been approved by the contractor. Secondly, a detailed work of the contractor to submit Tally was presented with the program. The project architect, said the program presented the detailed program and has been involved in programs subcontracting aluminum plants and water works will be resubmitted. daily and monthly progress and the progress of the program and the program will be presented. The resident engineer reviews these programs with the Master’s program above and the contractor will be recommended to increase the cost of labor, equipment, etc., to avoid delays and delays to catch up. Progress is still under review progress meetings as compared with the control program and further instructions will be issued checks. The contractor will not start accumulating for about two months. The reason for this delay was the inability of the contractor has been chosen to mobilize stack, because the machines available piling have been raised in other places. The contractor has not requested an extension because he believes that the backlog by increasing labor and machinery. For this reason, the program presented to be amended and resubmitted. The program has been reviewed by the project architects and proved false. There were complaints that the amount of work he has done over the last two months are up too. The work required is very high. The contractor, the program adjusted accordingly and the comments have been made new. The project noted architect and project manager once the program is impossible. This has been submitted to the contractor, the contractor does not agree. Progress on site every two weeks with the participation of the contractor and its employees will be relevant, given the sub- contractors concerned supervisor consultant, the project architect and client representatives. At the first meeting, the client has been invited to give the client project coordinator. At the time of delivery of the building began to build, is the client requests to attend meetings of the week to hold. CONSULTANT has stressed that not enough progress to check each week.
