Measurement, Cost Estimating and Analysis

There are TWO tasks on measurement, cost estimating and analysis in this brief. They cover building/civil engineering work measurement and cost estimating for Project A, and Project B.

Assume that you are well into the fourth month of your new job as quantity surveyor with a project management firm that has been appointed by P&G LTD, a private organisation, to manage some of their projects. You have been assigned to a team that oversees two of their important commercial development projects which are both at the preconstruction stage. While one is a residential building (x4nr), the other is a sensitive material warehousing facility, concrete framed and with some structural steelwork.

The director in charge of these projects has given you the following tasks to complete within one week, in time for the next meeting with the client who wants to begin to gain a sense of the actual cost of Project A and also award the contract for Project B, if a decision can be made.

Task 1/Project A - Residential building

The Architects for project A, have started to develop working drawings and have shared the current revision with your organisation. The drawings include foundation layout ground floor, sections and elevations and others. These drawings are still incomplete, but your director wants you to prepare unpriced bills of quantities for the identified items to the extent of detail afforded by the drawings. You do not need to price the items.

Wherever necessary, raise queries and state your assumptions and include them in an appendix to your work.

This task refers to the following documents:

• 05/076/BR-03
• 05/076/BR-04
• 05/076/BR-05
• 05/076/BR-06
• 05/076/BR-07
• 05/076/BR-23
• Internal Finishes Schedule

• Specification (See appendix)

You are required to undertake the following tasks:
Using the drawings and specifications to measure the relevant elements of the building described below: Substructure to include
• Excavating and filling; insitu concrete works; walls up to and including the DPC

Superstructure and Finishes to include
• Walls (Include take off for pre-cast concrete lintels, steel lintels and structural steelwork)
• Carpentry (Wall plates, fascias and soffits only for this coursework)
• Dry-lining systems
• Windows and external doors (enumerated/measured as composite items, including frames)
• Floor insulation
• Finishes to floors, walls and ceiling. (Screeds, external render, skim coats to dry-lining)
• For carpentry, roof covering and associated work, please include a provisional sum of 18,500 pounds. This means you do not need to measure the roof work in detail.

If you find any errors or discrepancies in the drawings, please develop a query sheet with assumptions to be confirmed. Your measurement will be based on the assumptions you have made.

Prepare a list of further items still to be measured from these drawings and not included in the above.
• Prepare a bill for the substructure, superstructure and finishes, using the elemental billing format. For this, you will need to use the NRM1 and NRM2. You will find the PDF versions of these documents on Moodle. Also, digital formats of the standard methods of measurement have been included in the assessment pack for use within Cost X.
• The structure and descriptions need to be of the standard recommended in the NRM1/NRM2 for elemental billing.
• Note that you will need to create two ‘buildings' within cost X for this Coursework-one for project A and another for Project B. Your submission for this task will consist of the Cost file export and a printed report (bill) from Cost X for Project A.

Task 2/Project B - Basement/pile cap and piling work for a material warehousing facility

The second building/project is a valuable material warehousing facility. The works will begin with piling and associated work, and after that, the basement slab, which is also the pile cap. Tenders for the works have just returned to your organisation (the PM firm). Also important to note is that the tender documents did not include bills of quantities, so the contractors who submitted offers for the works have prepared their pricing document independently.

Now you are required to analyse and report on the tenders before the end of the week. The director has, therefore, asked that you prepare a priced bill for the works in accordance with the CESMM4 rules for measurement and description. This is mainly to serve as a basis for comparison.

As a general guide, you should include the following:
• Bored cast in place concrete piles and piling ancillaries
• Concrete and concrete ancillaries including reinforcement
Waterproofing underneath and to the sides of the basement slab will be done by others so it should not form part of the contract.
You can obtain prices for the items measured from the BCIS online database of rates for Civil Engineering projects.

Please also include a sum of 50, 000 each for two pile load tests and add 10 per cent of the total estimate for preliminaries and General items. The rates (BCIS) are from 2014, so you will need to rebase them using the Tender Price Index. Also, allow for 26% mark-up.

Once priced, you will then need to compare your estimate to those submitted by the two contractors RICKY LTD AND BADGER LTD after checking them thoroughly. The third contractor LKR LTD has decided not to submit.

Please produce a 500-word (not exceeding) summary/report based on the prices submitted by the contractors that could help your organisation make a sound judgement and recommend a contractor to whom the work should be awarded if possible.

The marks for this task will be distributed equally between the measurement/estimating and tender analysis tasks. If your estimate is flawed, then you will only lose some marks for that part of the task. The second part will then be considered on its merit, based on your estimate, flawed or not.

Your submission for this task will consist of the Cost X file export and a printed report (bill) from Cost X for Project B and the 500-word summary/report. Please also include any spreadsheets used in arriving at your conclusions (not more than three pages of analysis of the tenders). What you have in the spreadsheet will depend on what you intend to present to the client.

The assessment pack for this task includes the following documents/drawings:
• Basement slab layout/details
• Pile sections and reinforcement details
• Tenders submitted by RICK LTD and BADGER LTD (be sure to check them thoroughly and compare them to your estimate (task 2 only))
• CESMM4 PDF extracts - you do not need these much. A digital version for Cost X has been provided.
• CESMM4 standard phraseology of descriptions
