Building Construction 4. tender offer

  1. 1. Building Construction Technology IPractical Session no. 416.04.2012Answer these Questions : - When should the Architect or the Investor invite the contractors to the tender ( how many days before the tender) ? (4-6 weeks) - The restriction on the number of the contractors that can participate in the tender is due to what? And the maximum number of participants is? (is due to the expanses that they have to pay. And the maximum number Is 6) - How much time can be given to prepare the tender documentation? (it depends on the size of the project, for smaller once it is about 3-4 weeks) - What is the procedure of changing the tender offer? Who can do that and how? (contractors should not make any changes. They should instead send an enquiry min. 10 days before the tender date. Architect should send a reply to all contractors to provide them all the same chances) - Explain the withdrawal of the offer? (tender offer can be withdrawn by the contractor at all times, as long as it has not been chosen by the investor. Acceptance of an offer constitutes an agreement between the investor and contractor) - Which alternatives have the contractors when the designer find an error in the tender documentation? ( "Alternative 1" – where the contractor can confirm or withdraw the offer and "Alternative 2" - where the contractor can confirm the offer or correct mistakes) - Who is responsible for surveying the works? ( the Contractor ) - Bill of quantities is: (a list of all required works (with all measurements already made) – the contractor needs to provide their rates for each of the works.) - Write something about Gantt chart: (Gantt or Bar chart is the easiest available planning technique, and probably the only one commonly understood without prior training. Despite its simplicity, a correctly designed chart will provide a lot of information necessary to complete the project. Each line on the chart indicates a task or group of tasks necessary in the project. The length of a bar is relative to the time necessary to carry out a task. Individual tasks stand in
  2. 2. dynamic dependency relationships that reflect the order of completion. This allows for a fast check of how, e.g. a delay of task A will influence the completion of task C, taking place 2 months later. )- Purchase schedule is used for: (which indicates the deadlines for making orders. All data is dynamically related, and therefore if the installation of windows, which have to be ordered 4 weeks in advance, is delayed, the schedule will automatically suggest new order date.)- Mention two problems of schedules? (One must bear in mind that schedule is a dynamical tool which needs to be regularly updated in order to serve us most efficiently. Every construction plan is appropriate only until the project has started. It can be often seen, that our plans do not reflect reality, in which case the plan must be updated, otherwise it will lose its adequacy. Plan is only as good as the person who created it. Software is only a tool, not a magical solution to all our problems. If the project deadline we set is not realistic, there is no plan which will make completion on time possible.)
