6.1 Changes to the original scope of work may only be made by one of the following: Bulletins issued in numerical order before award. Addenda issued in numerical order after award. Construction Change Orders (CCOs) issued in numerical order after the contractor is on-site [referred to as Construction Change Requests in Europe (CCRs)].

6.2 The contractor is not authorized to proceed with any work beyond the original scope of the contract without written authorization by the Purchaser representative.

7. GENERAL

7.1 The purchaser sets high goals in safety and quality, and all work performed according to this specification shall comply with safe and quality-conscious practices.

7.2 For the complete responsibilities of the contractor under the purchase order contract, all relevant drawings, specifications, and associated documents as listed in the purchase order contract shall be read in conjunction with this document (for example, 4WCE-670200 for piping erection). The contractor shall undertake all work according to the contract drawings, drawing notes, standards, and specifications referenced herein. The contractor shall only employ personnel trained and competent in the work they are being asked to do. Equipment and plant shall be serviceable and shall be inspected with suitable certification. The contractor’s employees shall at all times use best trade practices in the work being performed.

7.3 The contractor shall be aware that the intent is for the scope to be fully inclusive of all activities necessary to complete the erection of the facility from receipt of equipment to handover ready for commissioning. Where the contract is awarded on a bills of quantity basis, the contractor, as an experienced contractor, shall ensure that their offer is fully inclusive and the contractor shall identify any activities they consider omitted from the bills of quantity activity listing and include the price for these accordingly in an appropriate rate within the bills of quantity. The scope of work, any bill of quantity, and drawings/specifications shall be viewed as a whole so that the contractor shall ensure that all scope/work identified, even if not identified as an explicit item in the bill, is priced within the general rates.

7.4 The contractor shall procure all gases for use at site, whether required in bulk form or cylinders, from Air Products or Air Products subsidiaries. This condition is subject to such gases being made available by Purchaser as and when required at no premium over local rates from other sources.

7.5 The contractor shall ensure that they make the best use of the free issue material provided. Adequate material has been provided for cutting allowances. For Monel materials or other exotic materials, no spare fittings will be provided and absolutely the minimum excess piping will have been provided. Under special conditions the Purchaser will provide extra material for welding qualification if requested by the contractor. The contractor will replace any equipment, materials, pipe, or fittings damaged or lost by the contractor. Within four weeks of receiving the final drawings and materials lists, the contractor shall confirm that sufficient material is being provided.

7.6 The contractor will be required to work alongside other contractors and often where there is limited space. Coordination between contractors shall be their own responsibility on a day‑to‑day basis. The Purchaser relies on the contractor to ensure that adequate communication occurs. The Purchaser will only adjudicate when contractors have discussed issues and are unable to resolve a conflict. The Purchaser shall not be liable for any failure by any contractor to adequately coordinate their work.

8. SCHEDULE

8.1 For this contract, time is of the essence. Failure of the contractor to complete the work within the scheduled completion and interim milestone dates specified in the contract documents shall constitute grounds for default of this contract.

8.2 The contractor shall furnish an outline bar chart schedule with the contractor’s bid according to the key date schedule and any specific form included with the bid documents. The contractor’s schedule shall be activity based, if specified, using any breakdown provided in the tender/bid documentation. It shall clearly indicate weekly manpower loading for direct, indirect, and subcontract labor and the scheduled start and completion dates for each item.

8.3 For the execution of the contract, the contractor shall generally develop a critical path network (CPN) for the project. In the United States within two weeks after contract award, Purchaser themselves, with the assistance of the contractor, will prepare a detailed construction schedule (based on the contract and pre-award agreements) to be issued to the contractor for review. Interim, milestone, completion, and commissioning dates detailed in 600.002 will be used as the basis for development of this schedule.

8.4 When not done by the Purchaser, the contractor’s schedule shall be at an activity-based level of planning with a suitable method of progress measurement agreed with the Purchaser representative. The following paragraphs outline the expected method of planning a mechanical-based contract; however for other disciplines, a suitable equivalent shall be used (for example, numbers of terminations, loops, cables pulled, concrete poured). For a mechanical-based contract, this should indicate the interfaces between prefabrication, blast and prime painting, erect, weld‑out, support, punch-out, and test. The activities shall be resource loaded with durations to enable the production of a resource requirement histogram. After resolution of any necessary changes and final agreements, the contractor shall sign the original copy of the schedule. This signed and agreed-to contract schedule shall be binding with all requirements of the contract documents.

8.5 The contractor’s bid shall be based on the industry standard working week at the jobsite location, and shall comply with local labor laws. When not specified or controlled the preferred workweek is 40 hours ordinary time, preferably consisting of five 8-hour days. An alternate work schedule may be proposed for Purchaser acceptance provided that the contractor will furnish the labour, equipment, supervision, and other services required.

8.6When the contractor’s bid is based on the use of premium time to meet the schedule requirements specified in the project-specific key date summary, the bid must be specific as to where, when, and how much premium time is required and the incremental costs involved. Excessive overtime has proven to decrease safety awareness and increase incidents and to reduce efficiency. The normal scheduled workweek shall not exceed 60 hours or six days per week without approval from Purchaser management. Short unscheduled overtime will be left to the Purchaser representative’s discretion and approval.

8.7 All schedules must allow for inclement weather at the job site locale that might cause work delays or stoppages during the specific time of the year that the work is to be performed. No extensions to schedules will be granted by Purchaser unless unusually abnormal weather occurs and can be documented as such to Purchaser satisfaction. The contractor shall, therefore, include in the contractor’s bid, when appropriate, sufficient provision for accommodations (such as temporary shelter, heaters) that may be required to successfully complete the work in cold, wet, or inclement weather.

8.8 The contractor shall furnish sufficient workforce, supervision, and equipment and shall work such hours (including overtime, weekends, and holidays) as might be necessary to ensure completion of the work, as well as any established interim milestones following the agreed-to contract schedule.

8.9 Progress will be closely monitored regarding the contract schedule and if it becomes evident to Purchaser that the actual progress of the contractor is not in compliance with the contract schedule because of slow progress, delays in securing materials, insufficient or unqualified labor, incompetent supervision, negligence, or any other such cause within the contractor’s control, the contractor shall take prompt and adequate action to bring the work in compliance with the schedule and eliminate any interference with the progress of other contractors or production schedules. The contractor shall not be entitled to any additional compensation for additional labor, equipment, materials, overtime, or other methods that are required to maintain the agreed-to schedule.

8.10 The General Conditions assume that the contractor will be expected to perform extra work beyond the base contract work and within the original contract schedule. The provisions are detailed in the general and project-specific Terms and Conditions.

8.11 Failure by the contractor to comply with the requirements of these paragraphs resulting in additional costs incurred by Purchaser or other contractors (whose work is dependent on the successful completion of work by this contractor according to the agreed-to contract schedules) shall constitute grounds for backcharge to the contractor for these costs.

8.12 Fabrication Control and Reporting

8.12.1 The contractor shall develop a proposed fabrication sequence on a spool-by-spool basis, which shall be used to develop progress S-curves for spool fabrication. The contractor shall also determine the total numbers of spools to be prefabricated and quantity of welds.

8.12.2 The contractor shall report weekly on fabrication progress on both tabular and S-curve formats, split for each material type and summarized overall for the week period.

8.12.3 The report shall list the number of spools complete for the weekly period and cumulatively, the quantity of welds complete, and the percentage progress. All these shall be measured against planned progress.

8.12.4 The contractor shall also provide a similar report for blast and prime painting of spools based on the number of spools complete, and the contractor shall maintain a marked-up bar chart to be reviewed weekly, showing the progress of each spool through the fabrication process, including buildability status.

8.13 Site Erection Control and Reporting

8.13.1 The contractor shall develop a detailed erection plan based on the CPN that shall detail the installation of all materials, including installation of equipment, build-up of compressors, erection of piping, weld-out, support, punch-out, and testing to handover. When planning the work, contractor shall take into account the presence of other contractors who may be working on site at the same time. Purchaser cannot guarantee contractor free, uninterrupted access to work areas.

8.13.2 This plan shall be in bar chart form and shall be mounted on the conference room wall and marked up on a daily basis; a string cursor shall indicate “time now.” The progress against this plan will be reviewed in the formal weekly progress meeting.

8.13.3 The contractor shall develop and implement an effective method of allocating work to his field supervisors and of accurately monitoring progress.

8.13.4 From four weeks before the handover of the first systems, planning reports shall be available based on test packs/systems.

8.13.5 The contractor shall cooperate to the fullest extent with Purchaser, Purchaser customers, and other contractors and shall not be granted schedule extensions or additional compensation for any effect on contractor performance caused by other contractors executing their normal work in the same areas simultaneously.

8.13.6 Any overtime required for other reasons at the request of Purchaser will be authorized by issuing of a CCO. Only the premium portion of the overtime will be compensated to the contractor by Purchaser. It is the contractor’s responsibility to ensure that he obtains Purchaser approval for these CCOs and that timesheets are signed by Purchaser representative.

8.14 Phased Handovers

8.14.1 The contractor’s execution strategy shall allow for the phased start-up of the plant, which means that various process systems will need to be handed over in advance of overall mechanical completion. These handovers will form key milestones in the contract execution.

8.14.2 Accordingly, the contractor’s planning system shall be able to report on both “by area” and “by system” basis. The contractor shall also ensure that their field execution strategy will also enable this change of emphasis during the construction period.
