Lump Sum – Building where design is complete
Measured – Infrastructure work or ongoing work where the scope is known but not quantity
Cost Reimbursable – Early start required e.g. emergency works
Design and Build – Partial design where contractor takes over responsibility
Management – Trade packages are managed directly (no MC) – early start
Only EA (no QS role D&B) Undertake valuations L&E Final Account Value variations
Only EA D&B Chair meetings Instructions EoT Issue Certificates Certify Completion
CA – SBC EA – D&B
EA typically also undertakes QS duties but this is not assumed contractually i.e. could be different party but no formal QS role under D&B
Clearly outlines key discussion; agreements or issues, actions by when and by who
Intro’s actions from previous contractor report progress & issues change future meetings
Completion certificate – ensure time is not at large
Interim valuation certificate – Confirm agreed valuation between EA and MC
Gross valuation, less retention, less previous payments.
Agreed with the contractor and issued as “RfP” to the client (only “advice”) by EA/CA.
Implications; Rectification period begins - Half retention released - Client insures - LDs are not applicable
Employer must accept building early if it is actually complete
Take meeting minutes
Issue Instructions
Issue Certificates
Certify Completion
I undertook QS duties as well
Re-fitting of guttering pipes to adjacent delipated building as water was seaping onto the site and not into drain
Outline of works inc. rates & quantity#
Any impact on programme . date for instructions
UPS steps
D&B 14 days of instruction
Employer has 10 days to instruct
Contractor can object e.g. H&S issue
Employer pays for design work if not instructed
21 days SBC (14 days D&B)
Employer 7 days to instruct (10 D&B)
The employer can employ someone else to undertake the work:
Non- completion notice – ensure time was not at large to allow the client to issue LD’s if needed
States that on the date of the contract completion the works was had not satisfied the completion requirements
I considered both parties perspectives:
Contractor representative was faced with a difficult situation as it was clear he was not being provided with sufficient resource to complete project
Client – Had not issued LD’s and had aided the MC with the project but was not seeing much improvement
How does D&B differ to SBC contractually?
Contractor responsible for design No listed subcontractors, No architect/CA/QS (EA only), No clerk of works, No payment certification – contractor applies and employer decides how much
Roles/Responsibilities of: Client COntractor QS CA EA
Client - Pay, Possession, Insure, Not obstruct, Pay Less if does not agree/LDs
Contractors – Complete Work & Design, Comply, Inform EA of discrepancies
QS – Only EA (no QS role D&B), Undertake valuations, Confidential, L&E, Final Account, Value variations
CA – Only EA D&B), Chair meetings, Inspect work, Instructions, EoT, Issue Certificates, Certify Completion
EA – As CA but for D&B, typically QS but contractually is assumed as different party
