Procurement

What is procurement?
1. The overall process of acquiring construction woks or services?
Factors affecting the selection of the type of procurement
1. Scope of wk: size, complexit
2. Programme: start/ finish dates
3. Client Brief: commercial/ public sector etc.
4. Risk. priority: time, cost, quality
5. Current mkt: inflation, financial stability, availability of specialists skills etc.
Types of Procurement
1. what are the main procurement methods?
  1. Design and Build
    1. Design and Build procurement
      1. what is it?
        where the MC is responsible for the design, planning, organisation, control and construction of the works to the employer
        the Emp. sends out a set of ER & the MC responds with Contractors Proposals which inc the price 4 the wks
      2. how does it work?
      3. when might it be appropriate
        where there is a need 4 an early start on site: can overlap design & construction
        where Emp wishes 2 min risk: MC take on resp 4 design
        Tech complex prj: benefit of using MC expertise
      4. what contracts can be used?
        JCT
        D&B
        MP
        Not so much
        SBC +CD
        IFC +CD
        MW + CD
        NEC
        Options C/D/E/F
        FIDIC
        Conditions of contract 4 plant & Design & Build
      5. Advantages?
        Single Pt Contact
        Earlier commence on site
        Early price certainty
        use of MC expertise
      6. Disadvantages?
        clnt find it hard 2 prepare good ERs
        clnt commit 2 design really early
        variations from orig brief r difficult 2 arrange & £££
        Harder 2 compare tenders; hard 2 determine Value 4 £
        ease of fabrication may be priortised by aesthetic qual
        Maybe less real comp due 2 fewer d&B firms
      7. how much design input will the contractor have?
        dep on amount of design wk emp already done at tender
        can range from full design (design & dump) 2 production info and coordination only
      8. who carries out design for the contractor?
        can b outsourced 2 a seperate design comp (MC retain resp);
        MC might have in-house designers
        OR Clients team novated
        what is novation?
        a new contract that transfers the rights& obs of one contractural party 2 a new 3rd party i.e. design rights & obs of arch 2 MC
        if Client DT novated: - make sure there r Collateral Warranties in place 2 give remedies 4 breach of contract
      9. if the design team is novated, what should the client put in place ?
  2. Traditional/ general contracting
    1. what is traditional procurement?
      1. design completed by the clients design team b4 competitive tendering
      2. MC builds what the designers have specified
      3. Appointment of a contractor is commonly by competitive tender, but less usually by negotiation
      4. The client has control over design, quality. Generally there is no design responsibility on the contractor.
      5. design and construction are separate sequential processes
        programme for the project tends to be relatively long
      6. certainty on construction costs
        contract figure is usually known at the outset
      7. risks are balanced as between the parties
      8. e traditional lump sum approach in terms of cost, design and quality is a relatively low risk procurement option for the client
    2. when might traditional procurement be appropriate?
      1. If emp has design prepared
      2. f design is substantially completed by time of contract selection
      3. client wishes 2 retain control over design & spec
      4. cost certainty at start of site is important
      5. the shortest overall programme is not the clients priority
    3. what contracts might be used with traditional procurement?
      1. JCT
        SBC - Q/XQ/AQ

      2. Competitive fairness & transparent procedure
        Inc value 4 money
      3. Control over design & materials
      4. Price certainty b4 commencement
      5. well known procedures

      7. Programme commitment from MC b4 entering in2 contact
      8. LAD recoverable if delays
      9. early cost/ time commitment
    5. Disadvantages of traditional procurement?
      1. needs 2 fully detail design b4 tender
        if not complete b4 tender - cost, time cert reduced
      2. Pro duration may b longer than other types -its a sequential process
      3. no input into design and planning from MC
      4. strategy based on price competition
      5. dual point of responsibility - DT for design & contractor 4 construction
  3. Construction management
    1. What is it?
      1. Emp: direct contract with each trade contractors (TC) & utilises expertise of a construction Manger who act as a consultant 2 coordinate contract
    2. how does it work?
      1. TC: carry out wrk
      2. The construction man (CM) supervises the construction process & coordinates DT
      3. CM has no contractural link with TC ir DT
      4. CM role: prep of prog; determine req 4 facilities; b.down proj in 2 wrk pack; get tenders; co-ord & supervise wrks
    3. when is it appropriate?
      1. large/complex proj where ads of Cm r put 2 good use e.g. upfront buildability knowledge; prog advice; specialist input from TC;
      2. early start on site is KEY
      3. Flex in design, procurement, construction strategy
      4. where price certainty b4 commencement is NOT KEY
      5. where client is EXPERIENCED in construction
    4. what contracts can be used?
      1. JCT
        CM/A
        CM/TC
    5. Advantages?

    6. Disadvantages
      1. Price certainty not achieved until last trade package let
      2. changes 2 later packages may affect earlier packages - £££

        Man C is emp 2 contrib their exp 2 design & 2 manage construction and is paid a fee
        inital fee and staff costs paid throughout wrks
      2. How does it work?
        C. manager responsible 4 wrks & programme
        MC responsible 4 con wks BUT all physical wrks completed by SC
        Contracts between SC and Man. C
        Design developed by client consultants & construction commences b4 design is complete.
        final costs only determined when last pck let
        MC selects SC through competitive open book tenders
        Client reimburses cost of these packages 2 MC + fee
        MC role if low risk: gets a prime cost + fee

        MC contrib 2 design & planning process
        chg can b accommodated in packages as not yet let if they have no further impact
        wks let competitively @ current prices on a firm price basis
      6. Disadvantages?
        £ 4 wks not received until last package let
        chg 2 design in later pack many affect pack already let

        all members of a professional team become involved in the partnering process at the design stage (inc MC)
        Ownership of risk is spread between the parties and a collaborative approach is encouraged to delivering the solution and overcoming problems
        strategic partnering?
        A long-term relationship for a number of prj/works that will last over a long period of time. Framework agreements allow this and are then implemented on a project/project basis.
        Framewrok agreement - an agreement between MC/suppliers/emp. it provides an agreement to fix the T's & Cs for future purchases. subject 2 inflation
        key characteristics of partnering

        better predictability of time & cost
  5. Measured Term
    1. in the case where there will not be a tender amount or Contract Sum so the FA will need to b built up from zero amount to an 'Ascertained Final Sum' detailing measured and valued areas of the project
  6. Serial Contracting
    1. A new procurement strategy which provides an incentive to the contractor based on performance through KPI achievement as set out in the Contract. The Contractor will be awarded with an incentive project if project KPIs are met and project completed ahead of time.
Financial Basis of Procurement
1. Lump Sum
  1. contract sum is determined before construction work is started
  2. JCT Contracts ‘with quantities’ are priced on the basis of drawings and firm bills of quantities.
  3. JCT ‘Without quantities’ means a contract priced on the basis of drawings and usually another document, such as a specification or work schedules.
  4. synonymous with traditional procurement methods
  5. common law: contractor is entitled 2b paid lump sum when it completes the works (Construction Act gives contractors right 2 payment by installment)
2. Re-measurement
3. Reimbursable
4. Target Cost
  1. AKA: share gain/pain
  2. if cost exceed the GMP the contractor and emp share the extra cost of the overspend and likewise share the saving is below.
  3. INCENTIVE based 4 MC 2 manage effectively tendering & construction process & agree of account with subbies
5. Guaranteed or Agree Max Price
  1. A lump sum contract under which there is no adj of tender price unless SCOPE req. by client chgs.
  2. the MC inc add risk involced in design dev process in tender price
  3. ADVANTAGES:
    1. greater price certainty; MC takes risk of design dev & unforeseen occurances
    2. greater control of overspending - MC interest 2 alert the team to expensive items of Design Dev
    3. Quicker settlement of FA
  4. AKA: cost-type contract (also known as an open-book contract)
  5. What is it?
    1. contractor is compensated for actual costs incurred plus a fixed fee subject to a ceiling price
    2. contractor is responsible for cost overruns, unless the GMP has been increased via formal change order.
  6. DISADVANTAGES
    1. CLEINT pay 2 much - MC risk allowance may be higher than in reality
    2. Scope change are V. £££
    3. Can b adversarial - trying 2 decide whether changes are design development or scope cahnges
