Real estate class at UT Arlington II

When Ridgement company project introduction like Southlake and Turtle Creek project, we discussed bid invitation, estimate bidding and change order. The company uses electronic database bidding system for inviting the contractors. General contractors and subcontractors easily download the plans to calculate estimation online. Since some years ago, they have used timber line software which let them manage all change orders and accounting numbers for more efficient working. We discussed several documents for the bid , construction and contract documents. Contract form, condition of contract, specifications, drawings, addenda and contract modifications are for the contract documents with bidding requirement are for the construction documents and without contract modifications are bid documents. Construction documents are prepared by the architects and must understand the propose of these document. Specifications are complements of the drawings. They are written documents regarding quality, method and techniques of installation and desired performance. The CSI Master format is developed and published for the construction specifications. It is consisted with 16 divisions and each section is divided by General, Material and Execution. The contractor’s required insurance coverage are included contractual liability insurance, worker’s compensation insurance, liability insurance, personal injury insurance and automobile & property damage insurance. The contractors are usually required to obtain products and operations coverage after work completed. All amounts are specified in the supplementary conditions and must be purchased before starting construction work. Liens give the worker, contractor or material supplier the right to force the sale of an owner’s property in order to satisfy for payment. Without clear title, an owner may be prevented from transferring the property through sale. At the presentation time, I researched the process of shop drawings. Generally, shop drawing is prepared by contractors, subcontractors, material supplier or fabrication companies with graphically indicating the fabrication and installation of particular product. (AIA General Condition A201). Shop drawings are typically required for pre-fabricated components. Contractors need to verify actual materials and measure dimensions at field. The architect reviews contractor's shop drawing to match construction documents.
