Scope (design, financing, build) 2. Organization (delivery system) relationship between contracting parties 3. Type (payment mechanism) form of payment 4. Award method of assignment § The definition above applies to both contracts between private law subjects and for those between public entities and privates (public work contracts) § The combination of the 5 components allows, in theory, a wide range of contractual systems (typical of Anglo-Saxon reality) § The European legislation and the Italian jurisdiction, in practice, limit these possibilities especially in terms of public procurement Contract organization - Scope FINANCING DESIGN BUILD Contract organization - Scope § The scope of a contract can be segmented into: § Financing § securing a pre-spending, such as a short-term loan, and a subsequent long-term financing to develop the project, to be reimbursed with operational profits § Design § a process to detail the project scope, from broad concept, to technical specifications and construction drawings § Build § the performance of works, including preliminary activities (such as site preparation) and physical implementation Content Project delivery systems Delivery systems § Four possible scenarios: § Traditional § the contractor is only responsible for the physical construction of the specified project § Integrated § the contractor takes responsibility for both design and construction of the facility § Turn-key § the contractor is also asked to contribute to short-term funding § BOT § build-operate-transfer arrangements, where the contractor provides the whole scope, including life-cycle financing Delivery systems Owner Contractor 1. Traditional Design-Bid-Build 2. Integrated Design-Build Financing Financing Design Design Build Build 3. Turn-Key 4. Build Operate Transfer Financing Financing Design Design Build Build Delivery systems The delivery system dictates the risk allocation: the more the Contractor has to do, the more he is considered competent, and, skilled in doing the portion of the scope the Owner should leave risk on Contractor’s shoulders, as better fitted to deal with uncertainty 100% Owner Traditional RISK / KNOW HOW AGENCY CM CM at RISK Design/Build Turn-key BOT 100% Contractor Delivery systems - Traditional PROs Well known method Contractual Communicational Projectual flexibility Relationship Relationship Budget defined during tender Owner contractual protection Simple tender procedure OWNER Trust relationship with A/E Good system if uncertainty is mainly in the design General Design Firm CONs Contractor A/E Low constructability No fast-track Subcontractor Few interactions between parties Subcontractor Aggressive offers market(maximum downward auction) Subcontractor Difficulty in obtaining innovative forms of financing Very conservative design strategies High price of construction changes Not proper for high complexity projects Delivery systems - Pure / Agency CM PROs The involvement from the planning stages allows to: determine the budget early reduce the design risk cantierability and value engineering fast-track OWNER Selection of CM on a reputational/quality basis CONs Design Firm Fast-track C/M A/E could lead to redesign/rework extra costs Potential conflicts with other parties Trade Trade Trade designers contractor contractor contractor subcontractors general contractor (where applicable) Delivery systems - Pure / Agency CM Duties preconstruction suggesting to engineering company cantierability, value engineering, costs estimation, projectual options, schedule, financing, management and coordination, direction, etc. field supervision QA, monitoring and control, cash flow management, coordination and direction, change orders and claims, etc. “Agency” CM is refunded as “fixed fee on top of costs” operates as a professional Client-CM fiduciary relationship Deals with relationships with designers, GC, customer Acts as mediator in conflicts Delivery systems - Pure / Agency CM PROs Great flexibility for changes Reduction of subcontrating costs usually up to 5-8% savings per direct contract with subcontractors, rather than going through GC Reduction of operational responsibilities for customer Few conflicts between client and CM Low financial risk for PCM CM is the only point of reference Possibility to expel not suiting subcontractors CONs Low incentive for CM to reduce the price and time The client is the only one to assume the financial risk High risk of reputational losses for CM All parties must be involved from the beginning Delivery systems – CM at risk PROs CM usually offers a guaranteed maximum price (GMP) to ensure the customer that the project won’t exceed the budget: usually defined when the design is at 95% fee 10-15% Reduction of customer financial risk ( risk on GMP contractor contractor contractor Too late -> little value added on pre-construction CM no longer impartial, risk of conflicting relationships Changes, claims Contract hardly renegotiable (high change orders cost) Delivery systems – Design / Build PROs Exploitation of contractor’s design skills Cantierability maximization Fast-track Good system for high complexity projects Excellent internal coordination OWNER single centre of control and accounting Flexibility and agility for change management Customer risk reduction D/B Entity Construction Design CONs Function Function Lack of mediator The interests of DB usually prevail Subcontractor Subcontractor Subcontractor Low quality for DB profit maximization Customer must check quality Errors and nonconformities often revealed during final testing (reworks and disputes) Fast-track could lead to redesign/rework extra costs Delivery systems – Design / Build Customer Develops performance/functional specifications, needs framework, feasibility study / basic degin Stipulates the design and development/construction contract integrated with the design- build subject Contractor The subject can be an EPC company or an ATI/consortium (joint-venture) between design companies and construction companies Design-build uses subcontractors Also called EPC contract (engineering, procurement and construction) Delivery systems – Turn key Like DB but funded by the contractor at the end of the project It is also called “purchase of future thing” Widely used in Power and oil plants Lump-sum payment at final commissioning Often with initial coupled payment or some milestone payments Allows the customer to recover financial resources during the development of the project postpone the investment Delivery systems – BOT Funding by the contractor who realizes the investment against a long-term management fee Often “project financing” through vehicle societies (special purpose vehicle SPV company) Customer retains the ownership but resigns the management rights for 15-99 years, depending on the period required to guarantee MARR End users or the customer himself pay for the use Used for 𝑃 ! public-private-partnerships examples: EuroTunnel, Highways The buyer receives: Working plant Staff training Products in the predefined quantities, times and quality The relationship also involves the production (manufacturing) company and/or presupposes complex and prolonged collaboration forms Content Project payment schemes Payment schemes § Contractors are often highly risk averse § Recall risk premiums: Contractor willing to “pay” owner (charge less for contract) if owner takes on risk – if have to § For risks that contractor can’t control, may be willing to pay a risk premium to owner to take over § Contractor here will lower costs if owner assumes certain risk (essentially, paying the owner a risk premium) § For risks that contractors can control, cheaper for a contractor to manage risk than to pay a risk premium Payment schemes – Time and material The client pays the contractor the price agreed in the contract of: Labour employed Materials used and assembled Capital goods and construction site accessories The risk of higher costs is on the client Example Labour Developer 75 €/h for 50h Tester 50 €/h for 100h Materials Tools rental € 500 Training expenses € 300 20% of general business expenses recognized on the materials value Price paid to the contractor 75 # 50 + 50 # 100 + 500 + 300 # 1 + 0.20 = 9,710 Payment schemes – Unit pricing Once works are defined, unit prices are agreed for each individual category of work In situations of advancement at pre-established deadlines (generally monthly) the client pays the quantity of work categories actually made by the contractor The pricing regime can be fixed or subject to revision according to various parameters (inflation, etc.) Example Categories of work Foundation works 80 €/sqm Supply and installation of prefabricated plinths 1,550 €/each Total expected quantity: Foundation 100 sqm Plinths 9 Price paid to the contractor 80 # 100 + 1550 # 9 = 21,950 Payment schemes – Cost plus fixed fee Example: Cost Plus Fixed Fee Estimated cost 100’000 € Negotiated fixed fee 8’000 € Expected return on costs for contractor 8% Price paid, consuntive Case A Actual Cost 90’000 Price = 90’000 + 8’000 = 98’000 € ROC = 8’000 / 90’000 = 8.9% Case B Actual Cost 110’000 Price = 110’000 + 8’000 = 118’000 € ROC = 8’000 / 110’000 = 7.3% Payment schemes – Cost plus fixed percentage fee Example: Cost Plus Fixed % Fee Estimated cost 100,000 $ Fixed % fee 8% Contractor’s Return on Cost ROC = 8% Actual contract value at completion Situation A Actual cost 90,000 $ ROC = 8.0 % Price = 90,000 *(1+8%) = 97.200 $ Situation B Actual cost 110,000 $ Price = 110,000 *(1+8%) = 118,800 € ROC = 8.0 % Payment schemes – Target cost plus incentive fee Example: Target Cost Plus Incentive Fee No GMP Target cost 100’000 € Negotiated fixed fee 8’000 € Expected return on costs for contractor 8% Percentage on losses/gains 30% Price paid, consuntive Case A Actual Cost 90’000 Loss/Gain = 100’000 – 90’000 = + 10’000 Price = 90’000 + 8’000 + 10’000 * 0.30 = 101’000 € ROC = (8’000 + 11’000)/ 90’000 = 12.2% Case B Actual Cost 110’000 Loss/Gain = 100’000 – 110’000 = - 10’000 Price = 110’000 + 8’000 – 10’000 * 0.30 = 115’000 € ROC = 5’000 / 110’000 = 4.5% Payment schemes – GMP Example: Guaranteed Maximum Price GMP 112’000 € Estimated cost 100’000 € Negotiated fixed fee 8’000 € Expected return on costs for contractor 8% Percentage on losses/gains 30% Price paid, consuntive Case A Actual Cost 90’000 Loss/Gain = 100’000 – 90’000 = + 10’000 Price = 90’000 + 8’000 + 10’000 * 0.30 = 90’000 + 8’000 + 3’000 = 101’000 € ROC = (8’000 + 3’000)/ 90’000 = 12.2% Case B Actual Cost 110’000 Loss/Gain = 100’000 – 110’000 = - 10’000 Price = 110’000 + 8’000 – 10’000 * 0.30 = 110’000 + 8’000 - 3’000 = 115’000 € > 112’000 € ROC = (8’000 – 3’000 – (115’000-112’000)) / 110’000 = 1.8% Payment schemes – Fixed price Firm Fixed Price Suitable for professional services, usually well-defined or predictable Used for execution only contracts of works Fixed lump sum, paid: For partial deliveries (service orders only) On progress of works, generally monthly (construction) Lump-sum Turn-key Payment Flat rate, often upon delivery of the work, but they can be advance payments and interim payments agreed upon achievement of partial milestones System made "ready“ to work The contractor is the manager of all phases of the project – EPC Engineering, Procurement, Construction - and it is the only one interlocutor of the client The price generally has the possibility to be revised Payment schemes VS risk

COMPETITIVE BID (greater downward price) CAP (best technical offer and additional options a for a fixed price) NEGOTIATION (negotiation or tender based on the best offer) Design + Price proposal (best technical-economic offer) Time + Price proposal (best economic-time offer / financial) Bidding A contractor is selected by the lowest price proposal, in market competition Fixed price - low bid is win-lose Typically associated with lump-sum contract Qualifications are critical Variants: multi-parameter bidding Low bid plus arithmetic combination of other factors Low bid divided by ranking of other factors Bidding teade-offs Time provided to bidders to review documents Too long: Construction delayed Too short: Bids low-quality because too little time to review contract docs (incorporate high risk premium or unrealistically low) Few bidders willing to participate Bid count Too many bidders: Scare away best contractors Too few bidders: Bid not competitive Bidding process A/E oversight typical Publicity (specifies qualification requirements) Provide bid documents Typically include fair cost estimate, sample contract Answer RFIs Pre-bid conference Explain scope, working conditions, answer questions, documented in writing) Private VS public bidding Public Bidding Must be publicly advertised (posting in newspapers, public building, etc.) Qualification occurs after submission of bids Private Bidding May be by invitation only Qualification occurs before submission of bids Bidding - qualifications Common items for qualifications Bonds/Insurance (bid, performance, payment) Safety record Reputation Financial strength Total/Spare capacity Licensing Background in type of work Experience in local area/labor market Management system (QA, planning, estimation, control) Interest, adaptability shown Cap A fixed price (lump-sum) is set by the owner against which contractors propose a level of quality and options for the project Negotiation Typically selected based on reputation, qualifications Typically used for two cases Very simple Use trusted, familiar party Very complex/big Get contractor involved in design, start work early Requires relatively savvy owner Evaluate proposals, monitor performance Important even for DBB for post-bid changes Negotiation considerations Can get win-win because of differences in Risk preferences Relative preferences for different attributes Goal is to find a Pareto optimal agreement Key skill in negotiation: Ability to find win-win options Project contracting - Summary Separate Design and Scope Construction
