Preparatory work can be very different within a region, depending on the type and location of the construction. Because they take into account the installation costs of a construction contract, preparations tend to be higher in regions of high complexity. For Europe, a wide range of prime contractors` margins were recorded. Overall, most markets recorded margins of five to six percent. However, in overheated markets such as Amsterdam and Sweden, margins reach 10.0%. Hello, If you add to the following 2 cases, 1-If the employer and contractor have agreed on a revised completion date for the reduced scope of work, does a simultaneous delay affect the monthly operating costs of the preparatory work? Contractors should be careful and consider all preparatory work in construction contracts. Neglecting them and their costs can quickly exceed the possibility of a contractor and lead to disputes. Owners and contractors may want to include preparatory work in their contracts, as it is often expensive and difficult to distribute among all project activities. While the owner may specify the items that are considered advance payments, it is up to the contractor to claim the required amounts for each item. The contractor is in the best position to estimate these costs. The standard measurement method for structures describes pre-construction sections as such that contain elements that are not specific to work sections, but have identifiable costs. Although the legal definition of a developer and prime contractor is clear, there are other considerations when preparing the scope in terms of preparatory work such as access, protection of works, bank employees and custodians.
While the work can be done gradually during construction with different contractors in each section, does it make sense for each to provide their own access scaffolding, for example, or would it be better for the contractor to management to cover the item? Staff facilities Facilities are necessary if the company is to be the prime contractor and is responsible for the provision of toilets, toilets and meal facilities. The calculation is similar to the calculation of a site shed. The duration of the project, the type of facilities required and the cost per week of rental of these facilities must be indicated. However, it is common for bidders to simply give a percentage on the overall distribution of preliminary rounds, which can be frustrating when evaluating returns, although there are recommendations for this approach in some corners. According to «Elemental Standard Form of Cost Analysis, Principles, Instructions, Elements and Definitions, 4th (NRM) Edition», written by RICS in 2012 and published by BCIS, «the cost of preparatory work for the building to be analysed must be expressed and expressed as a percentage of the contract amount without any preliminary design, contingency and, where applicable, planning costs of the contractor». However, if you are in a position where you have identified a preferred bidder, a check may be performed at this stage to obtain a more appropriate breakdown. This breakdown is important for measuring and evaluating evaluations. Prelim templates are available from different sources and can be adapted to individual projects. For example, NRM2 provides templates for preliminary tariff plans in Appendices B and C of its guide.
Appendix B: Template for Preliminary Discussions (Main Contract) and Annex C: Template for Preliminary Discussions (Main Contract) Pricing Regime. When preparing descriptions or headings of the prelim in a price document, they must reflect the requirements of the contract as well as a specific method or phase of the construction work. It is good practice to include in the Prelims pricing document a statement that states: «The contractor is also advised to carefully examine the general and detailed drawings in order to determine the nature of the work and how it is to be carried out.» Simply put, the Code of Practice for Estimation, published by the Chartered Institute of Building (DDPI), describes preliminary work as follows: Subcontractors are likely to authorize preliminary work in the form of a direct percentage increase in the value of their direct work, based on the value of the construction package. If the overall work is of greater value, it would make sense to require a more holistic approach as required by the prime contractor. A percentage approach has advantages, such as. B ease of management in the evaluation of works and taking into account the value of variations. .
