Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
Also called caissons, drilled shafts, drilled piers, cast-in-drilled-hole piles (CIDH piles) or cast-in-situ piles, a borehole is drilled into the ground, then concrete (and often some sort of reinforcing) is placed into the borehole to form the pile. Rotary boring techniques allow larger diameter piles than any other piling method and permit ...
Commissioning procedures require a collaborative team effort and 'should' begin during the pre-design or planning phase of the project, through the design and construction phases, initial occupancy phase, training of operations and maintenance (O&M) staff, and into occupancy (for warranty and future re-commissioning).

Design–bid–build (or design/bid/build, and abbreviated D–B–B or D/B/B accordingly), also known as Design–tender (or "design/tender"), traditional method, or hardbid, is a project delivery method in which the agency or owner contracts with separate entities for the design and construction of a project. Design–bid–build is the ...
The construction industry has suffered from a productivity decline since the 1960s [4] [5] while all other non-farm industries have seen large boosts in productivity. . Proponents of Integrated project delivery argue that problems in contemporary construction, such as buildings that are behind schedule and over budget, are due to adverse relations between the owner, general contractor, and
The Construction Specifications Institute (CSI) is a United States national association of more than 6,000 construction industry professionals who are experts in building construction and the materials used therein. The institute is dedicated to improving the communication of construction information through a diversified membership base of ...
Virtual design and construction technology may be used by contractors to maintain a tight construction time. There are three main advantages to a design-build contract. First, the construction team is motivated to work with the architect to develop a practical design. The team can find creative ways to reduce construction costs without reducing ...
