Bid, Construction and Contract Documents

    We had a class at Ridgemont Commercial Construction in Irving Texas. The purpose of the class was learning field experience and discussing what we learned last week. Ridgement has diverse experience of commercial, hospital and residential construction.
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.
After 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.    After lunch, we went to sprouts farmers market job site at Hebron in North Dallas. With tilt up wall prefabricated system, they save time and materials at field. As reinforced concrete wall, they precast on the ground floor slab of the building and lift with a crane to its position. Since the connections of tilted up walls buildings are critical, embeds in panel and slab-on-ground are connected together through weld plates.
   Then we went to single family houses at Highland Park. With concrete and steel materials, the house was made with flexible custom design with the pool at second floor. In the living area, transparent glass makes outdoor yard as part of indoor space. However, many segmented spaces make people feel restricted and confused to find directions.
