sheets required . When incorporating an extra space or modifying an existing space , a separate drawing must be created to showcase the design option . This requires an additional number of sheet variations for one design and the rework is time-consuming .
2 . Open space issues – In a few cases , there is the lack of space to accommodate design options . This leads to a complete redesign of the home to provide space for this additional design option . To redesign a home to incorporate changes requires optimal utilisation of space . For instance , given the size of the home design within the site , adding a garage or porch may not be possible , which typically results in a complete redesign .
3 . Taking into consideration the building code requirements – There are basic building code requirements which must be considered when incorporating design options , such as standards for placement , structure , size , usage , floor assemblies , wall assemblies , location of rooms , roof structures and assemblies , stairs , railings , mechanical , electrical , plumbing , drainage , lighting , fixtures and energy efficiency standards . As there are other elements in the design which are impacted when redesigning a space , the building code requirements must be considered . For instance , increasing the living room space could reduce the width of a staircase which may not be within the building code requirement . Another instance could be a change in roof slope based on weather conditions which could translate to a complete redesign of the home to meet building code requirements .
4 . Difficulty in changing 2D drawing sets – Drawing sets are still produced in 2D , making it difficult to coordinate and detect flaws compared to when working on a 3D model . For the model to be accurate , the 2D drawing must be correct . To provide design options , changes must be made in 2D drawings with accuracy otherwise it could cost in terms of time and money invested .
5 . Lack of skilled resources – To incorporate design changes , experienced and skilled designers are required . A team of Revit technicians and designers that have the relevant knowledge in home design would be suitable for identifying the best possible method of dealing with changes in design and providing home design options in an efficient and costeffective manner .
6 . Keeping up with new building trends and requirements – There are new building trends and requirements in the industry , from energy saving to home automation requirements . Several home design options require designs which include new building requirements such as designs built to accommodate home automation devices or designs which are low in energy consumption and high on efficiency . Accommodating such home design options requires a knowledgeable team of designers that would be able to design options based on new building requirements .
Given the challenges , some ways in which to deal with design option changes in construction drawings include managing libraries to incorporate changes , using database-driven applications to facilitate accuracy , utilising a skilled and experienced team and involving key project stakeholders .
How to Deal with Design Option Changes in Construction Drawings
Homebuilders may have several plans , and there could be changes or requirements to showcase several design options . Here are some of the ways in which design option changes in construction drawings for houses can be dealt with :
1 . Manage libraries to incorporate plan updates – One of the ways in which home design options can be accommodated is by managing libraries of residential construction drawings
