2007 Standard Specifications for Road and Bridge Construction
General Style – Voice & Mood Use active voice and imperative mood for instructions to the Contractor. Example Old: Concrete shall be thoroughly consolidated against the faces of all forms and joints, including concrete in a previously constructed lane of pavement, by means of vibrators inserted in the concrete. New: Consolidate concrete against all form faces, joints, and previously constructed pavement using insertion type vibrators.
General Style – Voice & Mood Use the active voice for responsibilities of the Department. The Department will inspect the forms. Use the indicative mood when stating a fact. Approximate areas are shown on the plans.
General Style – Format Standard four part format for Div 200 to 800 ###.01 Description ###.02 Materials & Equipment ###.03 Construction ###.04 Measurement & Payment
General Style – Scope of Work – The Department will make payment for the elements of work described under the “Construction” or “Procedure” subsection under the corresponding Item in the “Measurement and Payment” Subsection. The Department will not make additional or separate payment for work or portion of work unless specifically provided for in the “Method and Measurement” Subsection.
Division General Information 102 Bidding Requirements and Conditions 103 Award and Execution 104 Scope of Work 105 Control of Work 106 Control of Material 107 Legal Relations 108 Prosecution and Completion 109 Measurement and Payment
Section Terms If the term is capitalized, it is capitalized in the Specifications Contract – includes permits, boring logs, pavement core records day – definition unchanged, but use of business day or calendar day has been deleted from the specifications, except where required by State statute. Utility vs. utility – Utility is a company, which provides services/ utility is a facility owned by the Utility. Work vs. work – Work is the entire project/ work is any portion of the Work. RE – term RE replaces Resident Engineer, with few exceptions other representatives with the Department are simply referred to as the Department rather than by unit or division.
Section Changes Quantity Increases/Decreases – bid prices hold only for increases and decreases that are within 25% of proposal quantity. Outside that, prices may be renegotiated. “Proposal quantity” does not include quantities designated on the Plans as “if and where directed.” IF AND WHERE DIRECTED quantities should almost never be used. It can be used with the SME’s concurrence, where we specifically want to insulate the Department from risk.
Section Changes IF AND WHERE DIRECTED items – Fertilizing & Seeding + 10% Traffic Control Items Prime Coat Tack Coat Construction Driveway Excavation, Test Pits Traffic Stripes Removal of Traffic Stripes RPM HMA Patch Sealing of Cracks and Joints Rumble Strips Flexible Delineators HMA paving items +10%
Section Working Drawings Table is provided for which drawings are certified and which are submitted for approval Ensure that the revised working drawings are submitted to the RE within 30 days of receipt of the conditional certification… The Department will require 45 days for review and approval or rejection and return of working drawings Special Provisions should revise the required # of days to review drawings if the project will have a # of drawings that the designer may not be able to handle.
Section Utilities Contractor required to send all Utilities within the project limits an initial notice when beginning construction operations. Contractor required to provide protection of Utility facilities as required by Utility (Designer’s should identify support requirements identified by Utility in design) Work by Utilities – the contractor is responsible for providing the Utility with advance notice as required in Special Provisions. (Must show durations for utility stages)
Section Environmental Protection Do not use treated timber products in shellfish areas and other environmentally sensitive areas. Use non-polluting materials such as fiberglass composites in these areas. Before using treated timber products in areas other than those specified in the Contract, obtain the Department's approval
Section Proprietary Items If material or equipment is specified using a proprietary item or the name of a particular supplier, the Contractor may propose a substitute except when the Special Provisions state that no substitution is permitted Designers must document the criteria for evaluating a proprietary item
Section Subcontracting Requirement for subcontractor prequalification with NJDOT procurement eliminated. Technical qualifications can still be identified with the Special Provisions (under the item of work). e.g. segmental bridge, drilled shafts, blasting.
Section Commencement of Work When a Request for Authorization Form for the New Jersey Pollutant Discharge Elimination System 5G3 – Construction Activity Stormwater General Permit (NJG ) is specified, the Contractor must not perform land disturbance activities until 35 days after the submission of the Request for Authorization Form to the Department (this should be identified on the designer’s construction schedule)
Section Maintenance within Project Limits Project Limits (area) defined in Contractor’s maintenance responsibilities for Project Limits: – Picking up and disposing of trash and debris – Keeping the roadway clear of dust, soil – Maintaining a safe and unobstructed passageway through the construction area including escape ramps at the edges of pavement. – Maintaining surface drainage – Removal of ice and snow from bridge sidewalks open to pedestrian access. – discuss with operations other sidewalk areas for which the DOT has ice snow removal requirement. Must be amended in the Special Provisions, when the project does not involve a fixed area (Operations Service Contracts).
Section Modifications to Contract Time If excusable noncompensable delays exceed 180 days, the time in excess of 180 days will be excusable, compensable. – Consider amend this to 90 days or less for projects with durations of less than 1 year Extreme Weather - Time extensions for weather only granted if controlling activity on critical path is delayed due to weather and the cumulative delay due to weather exceeds the number of days specified in Table for any month ( Designer’s Progress schedule should be based on normal # days workable for a given month. If an aggressive schedule is being provided – the table may need to be tailored for the project.)
Section Default Fails to begin construction operations within 40 days of execution of the Contract. ( Designer should amend this if start of work is restricted )
Section Measurement and Payment Measurement of Quantities Measured Items vs. Proposal Items. The Department will designate Items as Measured Items or as Proposal Items by having a suffix of P or M in the Item number. The Department will not measure quantities for Proposal Items, except quantities designated on the Plans as “if and where directed,” for payment. The Department will measure quantities for Proposal Items that are designated on the plans as “if and where directed” for payment when the RE directs work using the “if and where directed” quantity.
