- 7. 7 ECI EVOLUTION History ofECI in Langdon & Seah • In the early 1990s, our management foresaw the importance of early engagement of contractors especially during the pre-tendering stages • Attributed to the persistent shortcomings posed by the traditional procurement method whereby the contractors are engaged only after the designs have been finalised which resulted in unnecessary cost and time overruns
- 8. 8 ECI EVOLUTION Early Objectives •Early Start – rising land cost (and financing cost) • Better Construction / Pricing – more capital for land bids • More buildable solutions – enhance speed of construction
- 9. 9 ECI EVOLUTION Procurement Methods •Early Start – Forward Planning • Piling commence within 3 months after Building Agreement was signed (compared to 9 months in normal case) Better Construction / Pricing • Developers agree building construction costs prior to land bid – either with selected contractor lump sums or Unit Costs per GFA • Contractors will offer the best in terms buildable and constructable designs, easier / faster methods and sequence of construction etc. which will translate to both time and cost savings
- 10. 10 ECI EVOLUTION A Reflectionof Earlier Approach on ECI… ECI through Initial Engagement with Contractor to agree on construction cost on lump sum basis or unit cost per GFA … Earlier Approaches have not harnessed the full benefits of ECI and the initial engagement is not a full ECI process. What is ECI ??
- 11. 11 What is ECI? EarlyContractors’ Involvement ECI is a project delivery method whereby contractors are engaged mostly during the earlier stages of design (i.e. concept design or schematic design stages) To engage the Contractors early and to effectively tap their expertise especially in the areas of buildability, constructability, construction scheduling and planning, value management or value engineering and the latest construction technologies or methods

Model ECI AdvantagesDisadvantages 1 Design & Build (D&B) • Single point of responsibility • Allows Builders’ full inputs into design • Potential cost savings due to Builders’ inputs • Potential time savings due to shorter construction period, albeit a longer tendering period • Employer has to have a strong in- house project management team. Otherwise, Employer has to engage external consultants to assist in the development of design brief, preparation of tender documents and administration of the contract. • Complex evaluation of tender as design proposals submitted vary according to respective Builder (Tenderer). • Employer has no control of design as consultants are engaged by Builder 15 4 MODELS OF ECI Different Contractor Inputs for the Various Models Source: BCA ECI Guide

Model ECI AdvantagesDisadvantages 2 Design Development & Build (DDB) • Single point of responsibility • Employer retains control of architectural concept design • Allows Builders’ inputs into design (explore better and more effective technical solutions upfront) • Potential cost savings due to Builders’ inputs • Potential time savings due to shorter construction period, albeit a longer tendering period • Builders’ inputs in C&S and MEP aspects are restricted 16 4 MODELS OF ECI Different Contractor Inputs for the Various Models Source: BCA ECI Guide
- 17. Model ECI AdvantagesDisadvantages 3 Design Bid Build with Early Contractor Involvement (DBB-ECI) • Employer retains control of full design (for base tender) • Allows Builders’ inputs into design via alternative design solutions at tender stage, rather than after award of tender • Potential cost savings due to Builders’ inputs • Potential time savings due to shorter construction period, albeit a longer tendering period • More involvement from Employer and their consultants during tender period. • Builders’ inputs are further restricted as compared to D&B and DDB. 17 4 MODELS OF ECI Different Contractor Inputs for the Various Models Source: BCA ECI Guide

Hence, their inputs are further restricted as compared to D&B, DDB and DBB- ECI. Source: BCA ECI Guide

- 23. 23 ECI PRE-Q • Priorto ECI being put in place, it is recommended to have a Pre-Qualification exercise (Pre-Q) to select the most suitable contractors to tender for the project • For Public Sector projects, Pre-Q is conducted through open tender (2nd stage Pre-Q during subsequent ECI tender not allowed) • The Pre-Q process to be carried out should cover the following criteria:- • Financial Strength, • Resources & Capabilities, • Relevant experience, and • Current project commitments • It is recommended that the shortlisted number of tenderers for ECI be limited to between 3 to 5.

Substitution of Material is not Alternative Design. 4) Consultants are to evaluate Alternative Designs thoroughly. 5) Consultants are to follow up and close out on items that requires clarification from tenderers. 6) Alternative Designs should also result in improvement in productivity, safety and quality, buildability, Greenmark certification etc. 7) Unsatisfactory Alternative Designs should be rejected early. 8) Evaluation must be as objective as possible.

- 81. 81 ECI PROs &CONs Items ECI Tenders Conventional Tenders Demands on Time Dedicated timing; in the case of ECI, the intensity of the tender activities necessitate a dedicated team The fluidity of the closing dates provide time for introspections in between Commitment of Tenderers Because of the demands on time, it requires more commitments from tenderers Tenderers' commitments can be patchy; hit and miss Tendering Costs Costly; opportunity cost is also higher as tenderers have to give up other tenders to cope with this intensity; UK experience involves only one tenderer, with cost compensation if not successful Less costly, as tenderers can shift their interest between tenders accordingly Integrity of Proprietary Information Concern; as tenderers are expected to share their information with the other stakeholders; ECI usually seen as a front to mine information from tenderers and some may view the process with suspicion Relatively good, as tenderers may divulge proprietary information depending on the circumstances Interchanging of Information Good especially when presentation goes with the release of information by the Employer / Consultants; Consultants are accountable for the depth of information released Consultants' accountability will be sporadic and their input could be inconsistent and sometimes lack depth Timing of Design Input Both parties are encouraged to bring up the levels of details; Consultants have to be on their feet Lack of design details are usually translated into pricing of design risks by the tenderers resulting in higher prices; laggards galore Early Confidence The 'hand-holding' will encourage tenderers to be more confident about the project and therefore put in a more serious and robust price Tenderers of all ilk will put in a price basing on their own perceptions Construction Time Growing confidence could result in a more realistic construction programme Lack of interchanges of information could result in more risk-taking Last-minute Surprises Less last-minute surprises Tenderers can spring last-minute surprises whether it is construction methodology or interests Risk Management Better risk management Relatively less risk management

- 85. 85 RECOMMENDATION • ECI shouldonly be considered for bigger size projects e.g. S$200 million and above, or very complicated projects. • The number of tenderers shortlisted for the ECI should only be between 3 to 5. • Evaluation criteria must be as objective as possible inparticular in Design and Build ECI. • Confidentiality of tenderers design or alternative proposals must be maintained and protected. • Honorarium should be considered for unsuccessful tenderers in view of the efforts put in by them.
