ACH 231 Lecture 08 (Submittals And Shop Drawings) Part 1

  1. 1. Project Submittals what are submittals, shop drawings & mock-ups? review and approval process their role in the construction contract submittal management
  2. 2. Project Submittals PART 1: what are submittals, shop drawings & mock-ups? review and approval process
  3. 3. <ul><li>The working drawings and specifications prepared by the architect and engineers, although adequate for bidding and general construction purposes, are NOT suitable for fabrication and production of many trade-related construction systems. </li></ul>
  4. 4. <ul><li>Manufacture of the necessary project materials and equipment requires that the construction documents be amplified by detailed fabrication drawings and data that supplement, enlarge and clarify the contract design. </li></ul>
  5. 5. <ul><li>Such descriptive technical submissions are prepared by the producers/fabricators of the materials and are submitted to the general contractor and thence to the architect/engineer for approval before the items are ordered, fabricated and installed. </li></ul>
  6. 6. Basic Premise: <ul><li>Submittals are apart of the quality control process in the construction. </li></ul><ul><li>Submittals DO NOT become apart of the construction contract documents. </li></ul>
  7. 7. What are Submittals? <ul><li>Contains information concerning products and equipment that are to be furnished in the project. </li></ul><ul><ul><li>Product literature/data, samples, details, and colors </li></ul></ul><ul><li>Presented by the contractor to the architect for approval prior to the ordering and installation of any system or material </li></ul><ul><ul><li>A/E checks for conformance with the con. docs. </li></ul></ul><ul><ul><li>Confirms dimensions, colors, texture, sheen, pattern, details and installation procedures </li></ul></ul>
  8. 8. What are Submittals? <ul><li>Provides a means by which the architect and owner can confirm the intent of the design </li></ul><ul><li>General rule: everything that is installed into the facility requires a submittal </li></ul><ul><li>Goes through a lengthy approval process </li></ul>
  9. 9. Submittals are typically required for: <ul><li>Reinforcing steel </li></ul><ul><li>Precast concrete </li></ul><ul><li>Structural steel </li></ul><ul><li>Duct work </li></ul><ul><li>Electrical equipment </li></ul><ul><li>Manufactured roofs </li></ul><ul><li>Window treatments </li></ul><ul><li>Masonry construction </li></ul><ul><li>Fire protection systems </li></ul><ul><li>Millwork </li></ul><ul><li>Casework </li></ul><ul><li>Metal doors </li></ul><ul><li>Curtain walls </li></ul><ul><li>Permanent fixed furnishings </li></ul>
  10. 10. Submittal Package <ul><li>Transmittal to recipient </li></ul><ul><li>Product Data Sheet (Cut Sheet) </li></ul><ul><ul><li>model name and number </li></ul></ul><ul><ul><li>Performance characteristics </li></ul></ul><ul><ul><li>Manufacturer’s product specifications </li></ul></ul><ul><ul><li>Testing and performance data </li></ul></ul><ul><li>Shop drawings (or fabrication drawings) </li></ul><ul><li>Materials samples </li></ul><ul><ul><li>Color, texture, sheen, finish </li></ul></ul>
  11. 11. What are Shop Drawings? <ul><li>A supplemental drawing to the construction documents (plans & specs) that detail: </li></ul><ul><ul><li>Fabrication methods </li></ul></ul><ul><ul><li>Materials used </li></ul></ul><ul><ul><li>Models of product/system </li></ul></ul><ul><ul><li>Installation associated with product/system </li></ul></ul><ul><li>Include details, dimensions, and configurations of the item to be fabricated </li></ul>
  12. 12. What are Shop Drawings? <ul><li>Typically prepared by the subcontractor/vendor </li></ul><ul><ul><li>Then submitted to GC for review </li></ul></ul><ul><ul><li>GC forwards them to A/E for approval </li></ul></ul><ul><ul><li>Then drawings are sent back to GC to given to sub-c/vendor </li></ul></ul><ul><ul><li>Depending on action taken by A/E, fabrication usually begins or material order is placed </li></ul></ul>
  13. 13. Shop Drawing Example: Planter locations and Irrigation requirements
  14. 14. Shop Drawing Example: Hardscape details
  15. 15. What are Mock-ups? <ul><li>Physical models or small samples constructed to allow the A/E and Owner to review the appearance and function of: </li></ul><ul><ul><li>Materials </li></ul></ul><ul><ul><li>Colors </li></ul></ul><ul><ul><li>Textures </li></ul></ul><ul><ul><li>Other aesthetic features </li></ul></ul><ul><li>This is done prior to the inclusion in the physical construction </li></ul><ul><li>Can also be required for testing of systems </li></ul>
  16. 16. What are Mock-ups? <ul><li>Not always practical for every system to be included in building </li></ul><ul><li>Very useful when the expectation for quality cannot be easily conveyed in writing (specs) </li></ul><ul><li>Contract docs will specify the requirements for mock-ups </li></ul><ul><ul><li>Size, composition </li></ul></ul><ul><li>Contractor is encouraged to construct mock-up when it is not required in the con. docs. </li></ul>
  17. 17. Dry stack stone will be installed per the mockup wall on the right side of the expansion joint. Center for Integrated Nanotechnologies Los Alamos, California
  18. 18. A mockup of the exterior wall systems is being constructed to demonstrate how the systems will be integrated. Center for Integrated Nanotechnologies, Los Alamos, California

  20. 20. Submittal Review Process Vendor/Sub-Contractor prepares submittal package If Vendor prepares submittal, Sub-C will review package Sub-Contractor submits package to Contractor Contractor reviews submittal package and records information into submittal log Contractor forwards submittal package to Architect/Engineer
  21. 21. Submittal Review Process Architect reviews submittal for compliance with Construction Documents Architect will forward to Engineer if submittal is required to be reviewed A/E will comment on submittal (approve, revise, reject) A/E returns submittal to Contractor Contractor will record returned package into submittal log
  22. 22. Submittal Review Process Contractor will return submittal package to sub-contractor Depending on A/E Comment, the following actions take place: If submittal was approved by A/E with no comments Subcontractor will place order for materials/ equipment with vendor If submittal was approved as noted by A/E Subcontractor will place order for materials/ equipment with vendor with noted exceptions If submittal was marked “revise and resubmit Subcontractor has vendor make corrections and submittal process starts all over again
  23. 23. Submittal Review Process If the submittal was rejected A review of the construction documents takes place by subcontractor and vendor Usually a meeting with A/E is in order to rectify the problem Sub-C/Vendor will correct the problem, redo submittal And submittal process starts all over again
  24. 24. Submittal Review by A/E <ul><li>Architects will stamp submittal packages (including shop drawings) and note review </li></ul><ul><ul><li>Approved </li></ul></ul><ul><ul><li>Approved (as noted) </li></ul></ul><ul><ul><li>Revise and Resubmit </li></ul></ul><ul><ul><li>Rejected </li></ul></ul><ul><ul><li>Submit Specified Item </li></ul></ul>
