Case Study Flashcards
Why no PTE for Tower B?*
Late receipt of IFT
MC produces BQ (Client not want to pay us to duplicate BQ and then price)
Had I been granted time to do PTE, could take 1m,
and would be my estimate of cost overrun,
and did not want to delay procurement
Go to market would prove cost overrun, and would have fit-out VE expertise
Note:
- No PTE for MW package but probably don’t mention that
- furthermore, no indication of cost overrun (as assume designed to budget)
Opt C - VE:
How is VE incorporated into the LOA, and prioritised above outdated Spec and Drawings?
LOA is prioritised alongside PTC’s and VE
2 LOA, PTC schedules, VE 3 CoSC, 4 Spec, 5 Dwgs, 6 BQ 7 Any other
Note:
1 Subcontract agreement (not used on OZ)
Opt A - Redesign high cost items:
Did I propose this option to Client?
No, discussion with PM as time issues
The tenderers are requested to comply B2B with main contract, why is this?
B2B terms benefits MC
- Monthly administration of multiple packages
- Known risk allocation, can pursue at B2B costs
Did you consider D+B procurement route?
For early start on site
but the compromise is quality
Fixed as Traditional FPLS in the PS expenditure guidelines
Note:
Agreed before my time
Ignoring design development creep, the DD cost plan was 2017, do I think accurate if tendered now?
If tendered today, TPI may be cheaper re Covid
Notes: Tender Price Index (TPI) - Cost to Client - Inflation from the estimate to TR date - Tender Returns
Okay, so the ID was not developed since SD - what level of detail would you expect at DD?*
DD Specs, dwgs, door schedules
Enough to prepare a priced BQ (PTE) on
Enough to tender (not use PS)
Note:
- Detailed measurement of finishes (for schedules)
Is it really schematic if it’s just a general arrangement plan with no specification? Is this not more concept?
Agreed.
It is more akin with Concept. However, the drawings were titled as SD
I spoke with ID Consultant, who said its more SD, hence I used the term in my report
Why not wait for full design for Tower B ID?*
Client eager to early appointment of Contractor, and commence structural works
PS used to overlap design and construction.
Note:
- I appreciate it is best practice to await full design
- “General construction process i.e. certain packages always lag behind, for example, there’s little point developing ID to DD until structure is frozen. That’s why you’ll find nearly always, ID, MEP and landscaping are less developed and often end up being provisional sums”
Opt C - VE:
Can you provide an example of cost cutting?
Stone to cheap vinyl in resi corridors.
Note:
- Stone to carpet in resi corridors
- WLC - I advised carpet is cheaper but consider replacement costs over 20 years
How is this case study different to your daily activity on tender return overbudget, what makes it a ‘critical’ analysis/ case study?
Time critical
- No time for PTE
- On the critical path (of its Sectional Completion)
- Could of delayed tender process
Is MC entitled to loss of profit if PS reduced?
No. The Main Contract states that Prov Sums “may be used in whole, in part, or not at all”
Opt C - VE:
What is the VE process on OZ/ Tower B?
The tenderers submit proposals in PTC stage (without samples)
I collate and issue consolidated unpriced VE register to SC for tech review
Agreed VE implemented into award amount (and LOA - prioritised above Spec and dwgs)
Preparation - The ITT (invitation to tender) consisted of?
- General project details
- tender docs
- key contractual terms,
- project duration
- deadlines (TQ and tender return)
Note:
To receive the ITT the subbie has already been prequalified
Budget per m2 for residential apt?
AED 2,400/m2
Note:
=(AED 107m / 45 floors @ 1000m2 per floor)
What happens if discrepancy between mine and MC tender report numbers?
Happens. I discuss with Contractor and detail changes in my tender report
Why was single-stage tendering strategy chosen, for procuring Prov Sums?
We now have full structural design
employer can control design with the ID consultants engaged, who are developing design
Note:
- two-stage not require MC design development
- negotiation would be harder to achieve and demonstrate value
What is Dutch auctioning?
Unethical way to reduce tenders
Approach each bidder and say another tenderer will do it for X, can you beat this
You mention IFT was late, when was it due?
Resi fit out IFT - due Nov 18 (few months before)
Note:
- DD budget - approved Nov 17
- Resi fit out IFT - received Jan 19
Opt C - VE:
Definition of Value Engineering?*
Obtain best value, without impacting
- quality/ aesthetics
- performance/ functionality
- may be cost increase (but last longer LCC)
Reactive - corrective decisions when over budget
Notes:
Consider WLC - may cost more if e.g. high performance vinyl over cheap as specified
How many PS in Contractor’s initial procurement strategy?
57
Didn’t you have time to do a PTE after the tender docs were issued, prior to the tender return date 6 weeks later?*
Would of took me several weeks, at expense of other packages being procured
However, would of only shown cost overrun estimate. No time for redesign. Delay procurement.
So better to tender, confirm cost overrun, then have VE expertise on board to streamline process.
Note:
If IFT and Contractor BQ ready, I can and did PTE some packages
What are the risks of provisional sums?
Cost certainty
For undefined
- not priced in Contractor prelims
- no time allowed in programme
Recommendation - Package value started at, and end at?
Start AED 108m,
ended at 99m
= 9% saving
Opt C - VE:
Examples of VE in Tower B?*
expensive marble floor for a lower cost marble floor (e.g. Europe quarry to China) AED 3m
12mm to 10mm thick low iron glazing (balustrades, partitions)
cementitious ceiling boards to gypsum
Note:
- carpets to lower quality (similar look)
- In other packages, for example the Misc Metalwork, VE for hot dip galv ladders in BOH areas, from SS spec (as not seen)
Is the Tower B a defined or undefined PS?
Not stated in OZ contract as either, but..
Defined as MC allowed for time and prelims in tender.
Note:
- Defined is MC allowed for programme, planning and prelims
- Undefined is MC entitled to prelims and EOT as PS was complete unknown previously
You mention you were anticipating variations stemming from VE coordination issues, did you make a risk allowance for this and how was it calculated?
No risk allowance as unaware of ‘anticipated’, if I knew the coordination issues I would advise Supervision Consultant
Impact is lower for fit-out works e.g. thinner marble = more screed
Note:
- Assess on a case by case basis
What % of the contract value was the Tower B PS?
3%
Note:
99m/3.39bn
Analysis - Technical departures are dealt with by?
Contractor and Supervision Consultant
Captured in TQ’s and T-PTC schedules
Preparation - Was i involved in the prequal process?
No, Contractor led.
Prequal notes:
- P+L (financials) are requested.
- Ability to deliver local projects/ experience
- H+S record
- CV’s of staff/ organisational structure
How was the PS value set with no PTE?
/Do you know how the prov sums were calculated? If you had been tasked with them how would you have gone about it?
PS value based on DD cost plan (Nov 2017)
Contractor submitted their PS procurement strategy, and the cost plan costs were attributed to the Contractor’s packages accordingly
Opt C - VE:
Is it right to share the tenderers VE?
I discussed with Director and we approached Client, but Client instructed this, as per their procurement and tendering department rules
Aware it shouldn’t be default position
Opt C - VE:
What design stage would I suggest to undertake VE review?
earlier the better
- as more scope for change
- can track costs against cost plan drivers (e.g. if blockwork was assumed lightweight, and later designed as high density, VE opportunity)
Even if no cost overspend, you can realise further value
Note:
Generally at cost planning stage if overbudget
Why use PS in MW contract. What’s the advantages?
Expediate award and commence structural works
Flexible, can expand ‘in full, in part, or not at all’
Overlap design and construction phases
Recommendation - My role in the final negotiations at Employers office?
Employer led,
I know the package intimately and recommend the award amount - I provide rate analysis, Appendix A background and adjustments
Analysis - Do the tenderers have separate general requirements?
Yes BQ1.
Note:
However, it is not mandatory but helps administer variations
What did MC tender on with AED 2bn PS?
In competition for whole general requirements, structural works, PS mark-ups
Note:
- PS only architectural and MEP
- Large value as not fully designed, but enabled early MC award and start on site
Opt C - VE:
You acknowledged that each tenderers VE proposal should remain confidential and be to their commercial advantage. In this case, how you would have obtained uniform tenders? How would you carry out the Tender analysis?
If remained confidential, all would have been appraised individually
Up to the tenderer to put more effort into good VE proposals
What type of fit-out for the rental office?
Shell and core
Notes:
- Only fit-out to common areas - reception, lifts, WC’s
- Cat A Developer office - Basic MEP, suspended ceilings, floors
- Cat B is fully fitted office
Between the budget set in Nov 17 and resi fit out IFT of Jan 19, what typical factors could lead to additional costs in addition to design development?
TPI
- market conditions
- Contractor availability
- supply chain effect (e.g. covid)
Notes:
Design development - Agreement of spec (Between Client + ID consultant)
What do the PS and new rate % mark-ups cover for the subbies?
OH+P
for administering the change
