House Expansion

Assessment Task Detail and Instructions:
Scenario: A private client from Chelmsford wants to extend their house. The ground floor extension involves extending the existing kitchen to add a utility room and refit the kitchen. The first-floor extension involves extending a bedroom over the ground-floor extension.
At this stage, the client wants a detailed breakdown of the quantities and costs for the ground-floor extension works.

Task: This task consists of 4 parts as explained below.

1. Take off the works (work item descriptions and related quantities) up to the completion of the substructure works (demolition, foundations, ground floor construction works) as details illustrated on drawings and specifications.
   Measurements should be done as per New Rules of Measurement 2Links to an external site., 2nd edition standards, and recorded in dimension/estimating papers.
   In addition to the final descriptions and dimensions, show all your workings and calculations related to quantities.
   Appropriate assumptions should be made and stated clearly.
2. Produce an estimate of the cost for the works up to the completion of the substructure works (demolition, foundations, ground floor construction works)
3. Show all your workings and calculations related to the cost estimate. Appropriate assumptions should be made and stated clearly.
4. Discuss the estimating methods and sources of cost information/data used for estimating the works and their appropriateness (approximately 300 words).
   Suggested contents for the methods and supporting calculations
   -Explain overarching estimating methodology (unit rate estimating, operational estimation, or combination of both)
   -Provide references/details/evidence for sources of cost data for each item.
   -State any adjustments made for rates.
   -State how the estimate could be improved.
   Guidance Resources:
   You should be able to interpret partially completed drawings using the specifications provided. Advice regarding these will be provided during lessons and tutorials.
   New Rules of Measurement 2 – 2nd edition (NRM2-2nd Edition)
   Spons price books are available in the library online and one hard copy to support the cost estimate. Whilst cost data/rates are from Spons are not applicable for many of the items related to this project, this would provide vital information such as timing required for works/activities.
   You could look for prices online from popular building material sellers such as Travis Perkins or B&Q and other places where builders could hire tools.
