Marking Criteria – University Performance Descriptors
Using University Level 5 performance descriptors listed below, marks will be awarded for: evidence of justified assumptions; a professional and logical approach; technically correct calculations; accurate methodology and approach using extensive research appropriate to an academic essay layout on different types of tender evaluation mechanism using excel spreadsheet formulas and basic cost estimate backed up with all the quantities, cost data and calculations. See the more detailed guidance given for each task.

整修將分3個階段進行。 第一階段將是上層和底層的一半。 在第
Task 1 – LO1 – Identify and describe the QS functions under a variety of main contract
A project involves the refurbishment of a retail store. The project is to be carried out without a total closure of the store while refurbishment works are in progress. The store is located in the
ever-busy Kowloon City Centre Mall.
將繼續在底層的一半營業。 工程完成後，店面餘下一半的翻新工程將完成，新翻新的一樓和整個一樓的交易將繼續進行。 最後階段將完成外部立面。 這是最好的方法，將對客戶產生最小的干
擾。 第 3 階段將在商店在交易時間後關閉時進
The refurbishment will be done in 3 phases. The first phase will be the upper floor and half of the ground floor. Whilst refurbishment is taking place in the first phase, the store will continue trading on half of the ground floor. Once works have been completed, the refurbishment will be completed to the remaining half of the store and trading will continue in the newly refurbished half of the ground floor and the whole of the first floor. The final phase will be to complete the external elevation. This is the best method and will create minimum interference for customers. Phase 3 will be done at times when the store is closed after trading hours.

Make any other necessary assumption(s) to facilitate your estimating.
Submission of work
Your completed work for assignments must be handed in on or before the due date. You must keep a copy or backup of any assessed work that you submit. Failure to do so may result in your having to repeat that piece of work. Any item handed in must have, clearly written on the front:
your student number
the module number, title and the module leader’s name the date of submission
Penalties for late submission of coursework
Standard University arrangements apply. ANY late submission will result in 0% NS being allocated to the coursework.
Procedure for requesting extensions / mitigating circumstances
Applications for extensions need to be made using the standard form obtained from the Programme Manager at SCOPE, Hong Kong or by using the standard form obtainable online from e:vision. http://www.wlv.ac.uk/Default.aspx?page=14112. Further information can be found at http://www.wolvesunion.org/advice/academic/
Retrieval of Failure
Where a student fails a module (less than 40%) they have the right to attempt the failed assessment(s) once, at the next resit opportunity. If a student fails assessment for a second time they have a right to repeat the module, at additional expense and additional time).
NOTE: STUDENTS WHO DO NOT TAKE THEIR RESIT AT THE NEXT AVAILABLE RESIT OPPORTUNITY WILL BE REQUIRED TO REPEAT THE MODULE.
Return of assignments
Assignments will be kept for inspection by the external examiner.
Feedback sheets will normally be available after 4 teaching weeks from receipt in HK so as to review progress.
If you have any questions regarding your feedback you normally have two working weeks from the date you receive your returned assessment and/or written feedback or receive your exam results to contact and discuss the matter with your module tutor.
Cheating is any attempt to gain unfair advantage by dishonest means and includes plagiarism and collusion. Cheating is a serious offence. You are advised to check the nature of each assessment. You must work individually unless it is a group assessment.
Cheating is defined as any attempt by a candidate to gain unfair advantage in an assessment by dishonest means, and includes e.g. all breaches of examination room rules, impersonating another candidate, falsifying data, and obtaining an examination paper in advance of its authorised release.
Plagiarism is defined as incorporating a significant amount of un-attributed direct quotation from, or un-attributed substantial paraphrasing of, the work of another.
Collusion occurs when two or more students collaborate to produce a piece of work to be submitted (in whole or part) for assessment and the work is presented as the work of one student alone.
